Plant Manual for Koralle Lingonberry

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

Plant Description

Grow nutritious berries on compact shrubs! Fruits are high in vitamin C and make tasty sauces, jellies, and wines. Small pink flowers bloom in spring and repeat in summer, followed by two crops of slightly tart, bright red edible berries — first in late summer and again in early fall. Growth habit is suitable for rock gardens or as groundcover. Grows 12-18" tall and wide. Requires low-pH, acidic soil. Cold-hardy. Ripens in mid-August and mid-October. Self-pollinating.

Acclimate

Plants grown in a greenhouse must be acclimated carefully before planting or placing them outdoors. This is especially true in hot or sunny locations. Many species should never be grown in full sun. Before purchasing a plant, learn about its sun requirements. Knowing the plants requirements can avoid any damage to the plant by incorrectly giving it the wrong conditions.

If your plant has been grown in a greenhouse, here are a few steps we recommend you follow:

  • After purchasing your plant, place it outside in a sheltered, shady spot or on your back porch.
  • Leave it there for 3-4 hours and gradually increase the time spent outside by 1-2 hours per day.
  • Bring the plants back indoors each night.
  • Water it regularly to keep the plant moist.
  • Occasionally spray the leaves with water.
  • After 2-3 days, move the plants from their shady spot into morning sun, returning them to the shade in the afternoon.
  • After 7 days, the plants should be able to handle the outdoor temperatures, if they stay around 50 degress F.
  • After 7-10 days, your plant is ready to be planted in its permanent location. Try to do this on a cloudy day and be sure to water the plant well.
  • Observe foliage daily. If any type of leaf discoloration occurs, put the plant back into filtered light and attempt this step at a later date.
  • Special care must be taken to avoid burning the leaves.

These are general guide recommendations. Some plants take longer than others to acclimate.

Planting

Few things are as delicious as homegrown berries, and the success of your harvest begins right with the planting site and method. For maximum growth and yields later on, give your plants the best foundation possible.

Before Planting

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. Ideally, your lingonberries need a soil pH between 4.5-5.5. To amend your soil, use a soil acidifier. Steer clear of soils that are extremely heavy or very poorly drained.

Planting Tips

  • Pick a site with partial shade to full sun.
  • Space your plants 10-12 inches and space rows 1 foot apart.
  • Amend the soil with organic matter such as dehydrated cow manure, garden compost, peat moss or our Coco-Fiber Potting Medium.
  • Don’t plant too deep. The planting hole should be wide enough to accommodate the roots without bending. The crown should be right at the soil level, with the roots just under the surface.
  • If your berries are potted, plant them at the same depth as they were in the pot.
  • If your berries have bare roots, plant at the same depth as they were grown in the nursery row.
  • Soak your new plants with a solution of Stark® Tre-Pep® Fertilizer. (If planting in the fall, wait to fertilize until spring for best results.)

Additional Notes

  • Lingonberries spread by underground runners called rhizomes.
  • The biggest pest of new plants are weeds, mulch to help minimize the problem.
  • Protect your crop from birds with a Garden Net.
  • No pruning necessary at planting time.

Fertilizing

Cranberries and lingonberries require little fertilizer. In early spring, use a small handful of fertilizer (such as 5-10-10) and apply in a circle around each mature plant. Use smaller amounts for plants up to three years old. Stop fertilizing by late June.

Insects and Diseases

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

Aphids

They are the size of a pin head and vary in color depending on the species. Clusters on stems and under leaves, sucking plant juices. Leaves then curl, thicken, yellow and die. Produce large amounts of a liquid waste called “honeydew”. Aphid sticky residue becomes a growth media for sooty mold.

Natural Control

  • Sometimes you can knock them off with a strong stream of water from your garden hose.

Other Control Options

  • Consult County Extension Agent

White Fly

Adults are tiny, white winged insects found mainly on the underside of leaves. Nymph emerge as white, flat, oval shapes. Larvae are the size of a pinhead. Suck plant juices from leaves causing them to turn yellow, appear to dry or fall off plants.

Natural Control

  • Traps

Other Control Options

  • Consult County Extension Agent

Mealybugs

Adults are 1/4” long, flat, oval shaped with a white waxy covering. Yellow to orange eggs are laid within an egg sac. Crawlers are yellow to brown in color. Over winters as an egg or very immature young in or near a white, cottony egg sac, under loose bark or in branch crotches, mostly found on north side. Damage is by contamination of fruit clusters with egg sacs, larvae, adults and honeydew, which promotes growth of black sooty mold.

Control

  • Consult County Extension Agent

Botrytis Blossom Blight

Usually begins on plant debris, weak or inactive plant tissue than invades healthy plant tissue cause spotting and decay of flowers and foliage and fruits or berries.

Natural Control

  • Fall cleanup is essential.

Other Control Options

  • Consult County Extension Agent

Bacterial Leaf Spot

First appears as small dark green, translucent spots that later enlarge and turn black. Usually scattered over the entire surface of the leaf.

Natural Control

  • Serenade® Garden Disease Control

Fruitworm

Adult is yellow to brown sawfly beetle, 1/4” long. Larvae are brown and white, 1/8” long. Adults make slits in flower buds and larvae feed on berries.

Armyworm

Newly hatched worms are white with black heads. Mature worms are light tan or dark brown with dark or orange back and side stripes. They feed on the leaves of plants.

Pruning

Pruning is an important part of proper edible plant 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 (even the experts).
  • It is best for your plant to do some pruning versus no pruning.

Pruning Tips

  • Lingonberries require very little pruning except for the occasional removal of dead and damaged shoots every spring.
  • After the plant begins bearing regularly (in mid-June through late July), cut back all but six to eight vigorous canes in early spring.
  • Propagate plants in spring by splitting and separating crowns and transplanting clumps, be sure to leave part of the rhizome attached to the clump.

Spraying

Spraying is important to the survival of your plants. To handle potential diseases and pests, reference the guidelines below to know what you should spray, and when you should use it.

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

Watering

Cranberries and lingonberries require an average amount of water. If you receive about an inch of rainfall every 10 days or so, your plants will be fine. If you have a really dry growing season, give your new plants a good, thorough soaking with a hose.

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.

When to Harvest

You can start picking your berries the second year in late summer or fall (late September and October) once the berries are firm and fully red. The berries will ripen over several weeks so plan to pick more than once.

In warm climates, the berries may produce two harvests: one in mid-summer and one in mid-fall. The first harvest will be very small berries. Lingonberries are usually harvested by hand but you can also use a berry picker.

The annual average yield per plant is ½ to 1 pound.

Storage

Refrigerate immediately after picking your berries they will keep for a couple of weeks or freeze for later use.
