I have young paw paw trees that have been planted for 2 years now but not growing much..... they leaf out and look good during the season but are not growing "up" much at all. Any recommendation on how much and how often I should put this on my trees? I presume I would just soil drench the root ball with the mixed solution?
PawPawLover on Mar 23, 2016
BEST ANSWER: The fertilizer label recommends 10-day intervals as needed (and don't fertilize beyond July 1). Pawpaw trees grow best in partial shade during their first few years of life. It is a remnant of their nature as an understory tree. When they reach their fruiting years, full sun helps to ripen the fruit. A temporary structure with shade cloth can provide this without needing to move/disturb the tree.
How often should you use this on new trees? Older trees?
Irish17 on Feb 20, 2016
BEST ANSWER: Thank you for your question. The fertilizer can be applied every 10 days beginning in early spring up until June 30. We recommend a high nitrogen fertilizer once the tree reaches bearing age.
I just planted my dwarf apple tree, can I use this product now or should I wait a year or two to use this product?
Evelyn R on Mar 6, 2016
BEST ANSWER: Dear Evelyn, I use the Stark TrePep Fertilizer as part of the planting process. It gives the new tree a "pep". I plant the young tree and water well. Then about 1 week later, I feed the tree with TrePep. If you wait a year or two, you will have missed giving the plant the food that it needs to grow large and strong. Good Luck. Sharon

Can this be used on blue berry bushes?
Carolyn W on Feb 23, 2017
BEST ANSWER: I have used it on new blueberry plants that I got from Starks however Stark's sells blueberry fertilizer that is made specifically for mature blueberry bushes and I have used that also with great results!
Is this for 18 year established grapes?
Fritz H on Feb 14, 2017
BEST ANSWER: On the back of the product it states the following: "Later Applications:
May be applied at 10 day intervals at any time during the growing season for a quick feeding of trees and other outdoor plants."
So I would say yes it would be fine for feeding your mature grape vines. It is 22-24-12 so it is high in nitrogen and phosphate, so it would be a quick 'pick me up' for a nutrient starved outdoor plant. This would be good to use for an established plant before putting out some compost for an immediate feeding to the plant roots, allowing time for the compost to feed.
How can I raise the PH level in the soil ? Can wood ashes from a fireplace help ?
ROBERT W on Jan 18, 2017
BEST ANSWER: If your soil is already low/acidic, then you should be able to raise your soil pH using a garden lime or similar type product. Wood ash is also used as a liming agent (to raise soil pH) due to its high calcium content.
If i use this product do I have to use calcum or potassium in addition for my garden?
Ali ha on Apr 22, 2016
BEST ANSWER: Hello, If the soil is acid ,lime then calcium fertilizer as calcium nitrate should be added,and potassium fertilizer as potassium sulfate or nitrate in the late season of fertilization if crops with high demand of potassium such fruit trees or oil,tuber and some leaf crops are growing .
Best wishes . Falah
Hi. Can you use this on a October Glory Red Maple transplant? About 6 feet tall. Thank you in advance.

BEST ANSWER: Yes, you can use it for that. Just make sure you mix the fertilizer in water first so that you do not burn up the roots.
Is Tre-pep good for strawberries or rhubarb?
Susan J on Jun 21, 2018
BEST ANSWER: It's fine, but it's not nearly as good for strawberries as the Strawberry Food, which really focuses on developing the fruit. It really does make a noticeable difference in the size and number of berries you get. Here's a link to that if you're interested: https://www.starkbros.com/products/tools-and-supplies/soil-additives/stark-strawberry-food/
Should Tree Prep fertilizer be used if tree is planted in the autumn?
HollyB on Sep 1, 2017
BEST ANSWER: It's really better to wait until spring. You don't want to encourage tender new growth that will get frostbitten and stress/damage the tree.

is this appropriate to use on apple and pear trees also?
john D on Apr 5, 2016
BEST ANSWER: Yes - this fertilizer was recommended for the apple and pear trees I purchased from Stark Bros. Follow directions regarding timing for use. Hope this is helpful.
Does this work on blue, black, and raspberry's? Thanks
Michael L on Mar 28, 2017
BEST ANSWER: It is effective on berry plants, but you may want to take a look at the comments/reviews about the specialized berry fertilizers we have. They are specially formulated just for blueberries, raspberries and blackberries and will give you really premium fruit and lots of it. If you're interested, here is a link to a page with all of our specialty fertilizers: //www.starkbros.com/tags/stark-fertilizers
can you use this fertilizer on tomato and pepper plants?
Phyllis B on Mar 2, 2016
BEST ANSWER: Yes. It will help when transplanting trees, vegetables like tomatoes and peppers. I had 99 percent success in transplanting vegetables last year by using it. I don't use it as a fertilizer to support the plants through out the growing season because I like to incorporate products too like compost, earthworm castings and manure. I still have most of the contents of the bag and it last a long time if only used for distressed plants as an instant boost.
We planted dwarf fruit trees last spring, and now I am wondering if this fertilizer would be a good choice? It sounds like it is too late to use for this year, is there anything that we could use now or should we wait until spring?
stephanie h on Aug 6, 2016
BEST ANSWER: I don't recommend your fertilizing your fruit trees this late in the growing season. I do recommend that you commence fertilizing them as soon as they start putting leaves on next Spring. The Stark Bros. TrePrep Fertilizer has worked well with my peach trees that I planted in Spring, 2015 but I started fertilizing them in the early summer (I just got too tied up earlier to fertilize them sooner). I did fertilize them every 10 days according to the specifications on the package and stopped applying the fertilizer around July 1. They look great, have lots of growth and nice green leaves.
Hope this helps.
I have a dozen semi dwarf apple trees of different varieties that are about 4 years old. None of them have born fruit yet. They are 1.5 - 2" in diameter. They get good sun. Should I use Tre-Pep or would you recommend another fertilizer?
Peter on Mar 13, 2016
BEST ANSWER: I have had some dwarf apple trees as well that seemed to take an unreasonable time to bear fruit. I was talking to the wife while I was in my fruit tree garden last year and I told her that I was going to cut the tree down Because it never had any fruit. Say what you will about weather or not trees can understand what we say - but the next year there were apples everywhere. And my trees were at least 4" in diameter.
I do not think 4 years is an extremely long time for a tree to bear. Are the trees blooming at all ? If they are blooming but not bearing I would think it may be a weather related problem. I think the Tre-Prep fertilizer would be a reasonable coarse of action. Regardless of what fertilizer you use - I think they key to success is using the product as recommended.
I planted my plum trees a year ago, can I use this product now or should I wait another year to use this fertilizer?
Evelyn R on Mar 6, 2016
BEST ANSWER: Dear Evelyn, Wait until you see the leaf buds start to swell indicating that the plum tree is no longer dormant. Then feed the plum tree now and according to the package directions throughout spring and summer. Good Luck. Sharon
Is the tree Prep Fertilizer recommended for Hydrangea plants?
Louis on Jun 25, 2018
BEST ANSWER: This is an excellent all-purpose fertilizer, but it does not address the pH needs of plants like hydrangeas, which like acidic soil in order for the flowers to be blue. If you like pink flowers, Tre-Pep is perfect. If you like blue flowers, you need to add some soil acidifier: //www.starkbros.com/products/tools-and-supplies/soil-additives/soil-acidifier/
Can Tree Prep fertilizer be applied via a hose end sparyer to established plants, or will it burn foilage?
Lane B on May 29, 2018
BEST ANSWER: Yes, it works great in a sprayer. I've never had any issues with StarkTrePrep Fertilizer burning any of the trees, bushes or flowers I've used it on.
can product be purchased locally ?
Ray H on Apr 21, 2018
BEST ANSWER: I have only bought this through Starks nursery via the web. I live in Chesapeake Virginia and have limited number of nurseries.
Can I use a soaker water bag to apply this?
Steve W on Mar 4, 2017
BEST ANSWER: It should work, as long as you mix as directed on the package label and the mixture is fully dissolved before putting it into the bag. You should also thoroughly rinse the interior of the bags to remove any fertilizer residue after it has drained. This will keep the bags working efficiently. I would not recommend fertilizing every time you use the soaker bags, just fertilize as needed.
Its Aug 31st do I fertilize it zero when I receive peach tree?
Marilyn M on Aug 31, 2018
BEST ANSWER: Now is not a good time to fertilize, because you'll encourage tender young growth that will be damaged by frost/winter conditions. It's best to wait until bud break next spring.

Tre-pep and then some!
Soaked those bare roots and planted in big hole with top soil peat with coco-fiber and topped off with TRE-PEP twice a month until the 4th of July and those trees grew like crazy! I had a Red Haven crop the second year. Time for a big five pound bag!

Better than Miracle Grow
Been using this fertilizer for years and it's the best all-around fertilizer I've ever used. Every tree that I've planted using this fertilizer has not only survived but thrived. We live in Colorado and the climate here can be hard on plants and trees. One of the most difficult things to do is transplant wild Aspen trees from the mountains and successfully get them to grow in the city. We bought 10 Aspen trees from the Forest service that were 8 to 12 feet tall and planted them in Denver using Stark TrePep. They all survived the move and became beautiful mature trees! Also have used TrePep on all our houseplants with the same amazing results. Highly recommended!

Wonderful for apple trees
I purchased 4 apple trees, 2 years ago. 3 Fuji and 1 Gala. I used this fertilizer every 10 days, from the first week in April until the end of June. Within 1 year, 2 of the 4 trees had apples and all grew very well. This year (the third year), every tree has apples starting to grow.
I've used the fertilizer on 2 transplant trees and 2 ginkgo trees. It really does the job. I plan on purchasing it again next year when I run low. The 5 pound bag has lasted a long time and I'm very happy with my purchases from Starks.

Stark TrePep Fertilizer
I used this product to fertilize my fruit trees - Apples, Apricot and Santa Rosa Plum. The trees are doing well, and are nice and green. I like that I am able to mix the product with water and pour it around the trees rather than having to get down on my hands and knees to work it into the soil around the trees.

Great stuff!
I used TrePep on our new peach trees and by the third year we harvested just under 100 peaches from each tree. I also use this on our Heritage red raspberries and the yield has been tremendous.

I dissolve TrePep in five gallon buckets and then pour it around our young fruit trees and into our berry patches. Easy and efficient this way.

Tre-Prep
This fertilizer is the only one I have used and needed for several years, as it has met all of my fruit tree's nutritional needs during some highly variable weather, including four years of annual drought, when I used it sparingly to prevent burning.
