Plant Manual for Royalton™ Sweet Cherry

To the left, you'll find all the topics covered in this Plant Manual. Select a topic to read its information.

Plant Description

The biggest — and some say the best! This variety bears mouthwatering, 1¼" dark purple-red cherries that are rivaled only by Bing. Crack-resistant, even after heavy spring rains. The tree is a beautiful standout in any landscape during cherry blossom time. An excellent pollinator for other sweet cherries. Ripens in mid June. Best pollinator: another sweet cherry variety. A licensed variety of Cornell University. May be covered by U.S.P.P. #11107 or other patents.

Location

The best way to succeed is to plan before you plant. Let’s discuss location: Do you know where you want to plant your new trees? Avoid many future problems by considering all aspects of the planting spot, such as:

  • Cross-pollination
  • Sun and good soil
  • Check out the surroundings
  • Space wisely
  • Leave space for future planting

Cross-Pollination

Is a pollinator variety present? Cross-pollination by a different variety, of the same type of tree, is key to the success of many fruit trees. In most cases, its absence is why trees don’t bear fruit or produce poorly. Since insects and wind carry pollen from one blossom to the other blossoms the trees should be planted fairly close together, within 50 feet.

Sun and Good Soil

Your tree would love a sunny place with well-drained, fertile soil. But it will be quite satisfied with six to eight hours of sunlight. Good drainage is required to keep your trees “happy.” If your soil has high clay content, use our Coco-Fiber Potting Medium or add one-third peat to the soil at planting time. We do not recommend planting fruit trees in heavy, pure clay soils.

Even if your yard isn’t the most ideal location, take heart. Fruit trees are very adaptable and respond well to fertilizers, so they can get along well even where the soil is nutritionally poor. Just steer clear of sites with extremely heavy soils or very poor drainage.

Surroundings

If you’d like your tree to become a landscaping asset, choose the planting place with this in mind. Imagine it as a full-grown tree and check everything out: Wires overhead? Sidewalk underneath? Does it obstruct something you want to see? Can you keep an eye on it from the house? Will other trees be in the way, allowing for their additional growth in the meantime?
Even a year or two after planting, your tree will be very difficult to transplant. So take the time to plant it in just the right place.

Space Wisely

First-time fruit tree growers often ask about recommended planting distances from patios, sewer lines, water pipes and so on. Ordinarily, patios will not be a problem because the soil beneath them will be dry and compacted. Therefore, the roots will not grow into this area as much. It’s still recommended, however, that you plant at least 8-10’ away from patios, water pipes and sewer pipes. You might not expect sewer and water lines to be affected since they are buried so deeply. But, since sewer and water lines tend to be wet, roots will grow to them and around them if the tree is planted too close. By planting your trees far enough away from these items, you can avoid this problem.

Space for Future Plantings

Once you’ve found out about fruit growing goodness firsthand, you’ll want to expand your home orchard. It’s important to plan for tree spacing so that the future growth areas will be ready when you are.

Spacing between trees:

Dwarf Sweet, 8-10'
Semi-Dwarf Sweet, 15-18'
Standard Sweet, 18-25

Dwarf Sour, 8-10'
Semi-Dwarf Sour, 12-15'
Standard Sour, 15-18'

Planting

Successfully establishing a young fruit tree in your yard starts with your planting site and method. Once a fruit tree is established, it needs little assistance to grow and bear fruit; but you’ll want to make sure you give your trees the right foundation.

Fruit trees require fertile soil for good growth, so before you plant, check your soil pH. Contact your local County Extension Office for information about soil testing in your area, or purchase one of our digital meters for quick and accurate results. If the soil pH where you plant your tree is 6.0-7.0, you’re in good shape. Take a look at the established trees and plants around the site. If they look healthy and are growing well, just follow the recommended fertilization program for your fruit trees. Steer clear of soils that are extremely heavy or poorly drained.

Planting Steps

  • Before planting: soak tree roots in a tub or large trash can of water for one to two hours to keep its roots from drying while you dig. Do not soak more than six hours. DO NOT expose roots to freezing temperatures while planting.
  • Dig the hole deep and wide enough so the root system has plenty of room. (Keep the topsoil in a separate pile so you can put it in the bottom of the hole, where it’ll do the most good.)
  • Roots grow better in soil that’s been loosened, so mix in our Coco-Fiber Potting Medium into your pile of topsoil. You can also use dehydrated cow mature, garden compost or peat moss (up to 1/3 concentration).
  • Fill the hole, putting the topsoil back in first. You can avoid creating air pockets by working the soil carefully around the roots and tamping down firmly.
  • Create a rim of soil around the planting hole 2” above ground level. This allows water to stand and soak in. (In the fall, spread soil evenly around tree to prevent damage from water freezing around the plant.)

Post-Planting

  • Water your new tree. Deep, thorough soaking is best, with a solution of Stark® Tre-Pep® Fertilizer. (If planting in the fall, wait to fertilize until spring for best results.) This effective starter fertilizer helps trees and plants grow quickly and vigorously. After watering, if soil compacts, be sure to add enough soil to fill the hole to ground level.

Grafted Trees

Grafted trees need special planting attention. All Stark Bro’s fruit trees are grafted or budded, the only methods for growing true-to-name planting stock. You can see where the fruiting variety on top is joined to the root variety on the bottom by a bump in the bark, change in the bark color or a slight offset angle. For certain dwarf trees, it’s very important to keep this graft above the ground. Otherwise, roots could develop from above the graft; then your tree could grow to full size by bypassing its dwarfing parts.

Most Stark fruit trees are budded to specially selected clonal rootstocks. For dwarf, semi-dwarf and colonnade apple trees, the bud union should be planted 2-3” above the soil line. Standard size apple trees as well as our Custom Grafted trees should be planted 1-2” deeper than the soil lines from the nursery row.

For dwarf pears, peaches, nectarines, apricots, cherries and plums trees the bud-graft line should remain at or above the ground and for standard size trees they will do better with a slightly deeper planting.

Potted Trees

Stark trees that are grown and shipped in bottomless pots are part of our continuing quest for producing better and stronger trees for the home grower. By following these simple instructions, you will be assured of getting your young tree off to the best possible start.

  • Before planting: When your tree arrives, carefully take it out of the package, making sure not to damage any of the branches. The potted tree has been watered prior to shipment and should arrive moist, but it does need another drink when it arrives at your home. Be sure the container is moist clear through. If you can’t plant your tree immediately upon arrival, keep the pot moist until you can plant it and keep the tree in a sheltered location. DO NOT place your potted tree in a bucket of water. This could cause the roots to rot, and kill your tree.
  • Your tree is ready for planting as soon as it arrives at your home. Then, simply grasp the sides of the container and carefully slide the tree out. The potting soil should remain intact around the tree’s roots. You will want to keep this soil with the tree and plant it, soil and all, into the prepared hole.
  • Fill the hole with soil and water thoroughly with a solution of Stark® Tre-Pep® Fertilizer.
  • Your potted tree may have come with a bamboo stake, which helped straighten the baby tree as it grew in the pot. We recommend that you keep the tree staked when you plant the tree, as we recommend staking for all young trees of any type. You may remove the stake and replace it with a different style if you prefer. Tree Stake, the perfect strapping system for Stark Bro’s trees, comes with a sturdy fiberglass rod, and a revolutionary flexible strapping system that allows for movement and growth, available from Stark Bro’s.

One final point: Please be sure to remove the name tag from your tree. As the tree grows, this small piece of plastic can choke off its circulation, damaging or killing the tree. If you’d like to keep the tag on your tree, retie it loosely with soft twine.

Soil Preparation

Preparing your soil before you plant will greatly improve your plant’s performance and promote healthy, vigorous growth. It is a good idea to have your soil tested to determine if it is lacking in any essential minerals and nutrients. This can be done through your County Extension Office or with one of our digital meters.

The goal of soil preparation is to replenish vital minerals and nutrients, as well as break up and loosen any compacted soil.

When To Prepare Your Soil

Soil preparation can be done at any time that the ground is not too wet or frozen. Your trees may be planted even when temperatures are quite cool. If a hard frost is expected, it is advisable to delay planting for a while until temperatures become more moderate. Generally, as long as your soil is workable, it is fine to plant.

How To Prepare Your Soil

  • Roots grow faster when they’re spread out. Dig the hole deep and wide enough so the root system has plenty of room to easily expand. Keep the topsoil in a separate pile so you can put it in the bottom of the hole, where it’ll do the most good.
  • To loosen the soil, mix dehydrated cow manure, garden compost or peat moss (up to 1/3 concentration) into your pile of topsoil. Make sure the peat moss you get is either baled sphagnum or granular peat. You can also add our Coco-Fiber Potting Medium or 2 or more inches of organic material and work in evenly with the existing soil.

Your lawn can provide you with ideal organic materials such as grass clippings and shredded leaves. Not only will the grass and leaves break down to provide soil nutrients, but they will help loosen the soil as well. You can gather these in the fall with spring planting in mind.

Common soil amendments:

  • compost
  • sand
  • manure
  • lime
  • peat moss

Adding organic materials, such as our Coco-Fiber Potting Medium and compost will improve most every soil type. Organic materials bind sandy soil particles so they retain moisture and nutrients better. They also break apart clay and silt particles, so that water can infiltrate and roots can spread.

Soil Types

  • Clay and silt soils are made of very small particles. They feel slick and sticky when wet. Clay and silt hold moisture well, but resist water infiltration, especially when they are dry. Often puddles form on clay or silt soils, and they easily become compacted.
  • Loam soil is a mix of sand, silt or clay, and organic matter. Loam soils are loose and look rich. When squeezed in your fist, moist loam will form a ball, which crumbles when poked with a finger. Loam soils normally absorb water and store moisture well. Loam soils can be sandy or clay based, and will vary in moisture absorption and retention accordingly.
  • Sandy soils contain large particles that are visible to the unaided eye, and are usually light in color. Sand feels coarse when wet or dry, and will not form a ball when squeezed in your fist. Sandy soils stay loose and allow moisture to penetrate easily, but do not retain it for long-term use.

Fertilizing

Fertilizing is an excellent way to replenish the natural nutrients in your plant’s soil, especially nitrogen. Nitrogen encourages hardy green growth, which is exactly what you want to promote before your tree reaches its fruit-bearing years.

Fertilizing Tips

  • For a perfectly balanced fertilizer, use Stark® Tre-Pep® Fertilizer on all fruit trees at planting time.
  • Always follow application instructions on the product label.
  • If your new trees fail to put on 8-12 inches of new green growth each year, fertilize with Stark® Tre-Pep® again in spring.
  • You can usually withhold fertilizers until your trees begin bearing fruit (about 2-4 years).
  • After your trees start bearing fruit, apply Stark® Orchard Fertilizer regularly.
  • To prevent any chance of chemical burn, do not fertilize past July 1st.

Insects and Diseases

Every fruit tree has the future potential for disease and insect damage. Factors such as location and weather will play a part in which issues your tree encounters. Disease-resistant trees are the best option for easy care; and for all trees, proper maintenance (such as watering, fertilizing, pruning, spraying, weeding, and fall cleanup) can help keep most insects and diseases at bay.

Pruning

Pruning is a very important part of proper fruit tree care, but many people find the task overwhelming. It doesn’t have to be! Keep these things in mind:

  • You can have confidence in knowing that not everyone will prune the exact same way (including the “experts”).
  • It is definitely best for your tree to do some pruning versus no pruning.
  • There are three main reasons you should prune your tree: its survival, stimulation and shaping.
  • If a fruit tree is left unpruned, it will not grow well— and in some cases, may not grow at all.

Survival

When your tree is dug up from our fields to be shipped to you, the root ball loses many of its tiny feeder roots, which are needed to absorb moisture and nutrients. Pruning helps balance the top growth of your tree with the root system, giving the roots time to re-establish in your yard before spring growth.

When your Stark Bro’s bare root tree arrives, our professionals have already pre-pruned your tree for you. Because of this, you DO NOT need to prune them again when you plant. The only pruning done at this time would be any broken branches or roots.

Plan to prune your fruit trees during every dormant season. In Zone 6 and farther north, you should wait until late winter. A good reference book, such as Pruning Made Easy, can be invaluable for answering questions and guiding you through the pruning process.

Stimulation

In addition, cutting the tree back stimulates stronger, more vigorous growth from the remaining buds. After a single growing season, a tree you prune will be bigger than a matching unpruned tree.

Shaping

Even more important, your fruit tree needs to be shaped. The natural shape of a fruit tree is not always the best for maximum fruit production. Trees you receive from Stark Bro’s have been pruned in the nursery row for proper shaping, but correct pruning must continue at home. If you keep up with your pruning and shaping each year, you’ll make mostly small, easy-to-heal cuts.

Pruning Tips from the pros:

10 o’clock pruning angle.

  • Narrow, V-shape crotches are an open invitation to disastrous splitting later on, particularly when your tree is ripening with a large bumper crop. For your branches: choose wide 10 o’clock and 2 o’clock angles.

Pruning to a bud.

  • Make sharp, clean cuts close enough (about 1/4 inch) so you won’t leave a clumsy stub that’s hard to heal over. Stay far enough above the bud so it won’t die back. Slant the cuts and the new growth will develop beautifully.
  • Every branch has buds pointed in various directions. Since you want vigorous new growth to spread away from the center of the tree, make you cut above a bud that’s aimed outward. This helps your tree grow into a spreading shape.

Prune For Success

Fruit trees develop better if they’re pruned at the right times in the right ways. Here’s how:

Help the tree form a strong framework.

Remove weak, diseased, injured or narrow-angle branches, the weaker of any crossing or interfering branches, and one branch of forked limbs. Also remove upright branches and any that sweep back toward the center of tree. You want to keep your tree from becoming too thick and crowded; some thinning is necessary to permit light to enter the tree and to keep its height reasonable. All these objectives promote improved bearing, which is your overall aim. You’ll be pleased with the results.

Prune trees to Central Leader shape.

Trees do best when pruned and trained to a central leader tree. This type of tree has a pyramidal shape with a single upright leader limb as its highest point. This leader is the newest extension of a long, upright growing trunk from which all lateral branches arise. As with all strong growing branches, the leader should be headed at approximately 24-30” above the highest set of scaffolds branches. The uppermost bud on the leader produces a vigorous new leader, and no other shoot should be allowed to grow taller. Lateral limbs should be selected from shoots growing out from the central leader. These should be spaced vertically 4-6” apart, have growth that is more horizontal than vertical and point in different compass directions from the trunk. Any unbranched lateral branches should be headed back by approximately ¼ of their length to encourage side branches and to stiffen lateral branches. All laterals should have a wide branch angle.

Pruning Whips (Unbranched Trees)

Prune back to 28-36” above the ground at planting time. After the new branches have grown 3-5”, select a shoot to become the leader and scaffold limbs.

Off-season pruning

Sometimes pruning needs to be done even when the season isn’t the best. If a branch is broken by the wind or by a heavy load of fruit, emergency treatment is necessary. Prune back the ragged edges; making a smooth cut that leaves no stubby stump. Fast-growing “water sprouts” can be removed as soon as you see them rather than waiting until winter.

Spur pruning

Do not prune a spur tree as aggressive as a regular tree. Spurs allow fruit to form on each limb and bear from the trunk out. Spur type trees grow slower and develop many small spurs rather than long shoots, so fewer should be removed. Sometimes too many fruit spurs grow along a branch and will need to be thinned out to encourage bigger and better fruit on what remains.

Fruit Thinning

There are several reasons to thin fruit:

  • To reduce limb breakage
  • Increase fruit size
  • Improve fruit color and quality
  • Stimulate floral initiation for next year’s crop

Home gardeners thin fruit trees by hand. During May and June, many fruit trees will drop or abort fruit. This is a natural process that allows the tree to mature the crop load.
Trees may bear biannually, that is bear fruit every other year, bear heavy one year, then light the next year. Thin the heavy crop to correct bearing habit.

Apple Trees

The best time to thin apple trees is within 20 to 40 days of full bloom. Space each apple 6 to 8 inches apart on the branch. In clusters, leave the king bloom (the center bloom in the cluster of five flowers) as it will develop into the largest fruit.
On spur type varieties many fruit spurs grow along a branch and will need to be thinned out to encourage bigger and better fruit on what remains.

Pear Trees

Pear trees seldom require thinning. Remove small or blemished fruit as soon as they are seen. Leave two fruits per clusters to improve size.

Cherry Trees

These fruits are not thinned.

Spraying

A proper and consistent spray schedule is important to the survival of your fruit tree. From diseases to pests, many potential issues can be prevented with spraying before they even begin! To reap its benefits, spraying should be done consistently and thoroughly following the guidelines below.

Before you begin, read and follow all instructions on labels.

General Maintenance

Spray every 7 days with Bonide® Fruit Tree Spray as a preventative measure. Cease spraying 14 days before harvest. No more than 4 applications per year.

Spray every 7 to 10 days or after rain with Bonide® Citrus, Fruit & Nut Orchard Spray as a protective spray for fungal diseases. May be used up to day before harvest.

Watering

Unless you’re in an area where irrigation is usually needed for normal plant growth, you probably won’t need to water after the first growing year. Until then, follow these guidelines to get your new trees off to a great start.

General Guidelines

  • If summer brings about an inch of rainfall every 10 days or so, you won’t need to use the hose. But if it gets really dry, you can give your new tree a good, thorough soaking. The best way to do this is to let your garden hose trickle slowly. This gives the water a chance to soak in instead of running off. You can also use a soaker hose to water several trees at once. Give your tree enough water to soak the ground all around the roots.
  • It’s important to note that even if you’re in the midst of a brown-lawn drought, you don’t want to water too much. Once every 10 days or two weeks is plenty. Worse than dry, thirsty roots is waterlogged, drowning roots.
  • Although a little depression in the soil aids summer watering, it’s important to bring the soil around the tree up to the level of the surrounding soil for the winter. If not filled in, water could freeze around the trunk and injure the tree.

Harvesting

Are you ready to enjoy delicious homegrown fruit? Harvest is the time to enjoy the results of your hard work. Keep a few things in consideration as you reap the fruits of your labor: the best time to pick the fruit from your tree, and how to store the fruit.

Sweet cherry trees will start bearing fruit in 4-7 years under normal growing conditons with proper maintenance and care.

Sour cherry trees will start bearing fruit in 3-5 years under normal growing conditions with proper maintenance and care.

When to Harvest

One sure sign that red cherries are getting ripe is when the birds start visiting your tree for breakfast. But when it’s for lunch and dinner too, you’ll probably want to keep these freeloaders away. One way to do this is to cover your tree with lightweight nets. Our Garden Nets keep fruit safe from attack. They are easy to use and last for years. Thin tiny fruits within three weeks after bloom so your tree can produce large fruits you’ll be proud of.

Harvest season begins June thru July depending on the variety and location.
