Farnklin Y on Mar 23, 2020
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: My pawpaws stayed tiny for years as well. It required a lot of patience, I don't think we got any fruit until year six. Planted along with a Wells Pawpaw tree, now I have a gigantic harvest (I'm guessing we're at year eight or nine now). I think the trees spend the first few years working on the root system, so I wouldn't worry if your trees look dinky. When they finally take off, you'll be amazed at how fast they shoot up. The branches bend under the weight of all that fruit!
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.
what spray products and schedule should I use on some freshly planted semi dwarf, bare root, apple trees?
Ray H on May 1, 2019

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
I am looking for an organic fertilizer to use on Apple trees at planting, any suggestions?

David C on Sep 19, 2016
BEST ANSWER: It would be considered a synthetic fertilizer.
Hi. Can you use this on a October Glory Red Maple transplant? About 6 feet tall. Thank you in advance.
Chris T on Sep 2, 2018
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 used Stark Tre-Pep as directed until July 1, and plan to wait till spring to use it again for the semi-dwarf apple trees I planted this past spring and a semi-dwarf peach planted in 2015.. Before I moved to my current location, I had older fruit trees and I would fertilize them each fall with a slow-release fertilizer that I sprinkled in a circle near the outside edges of the branches, where I've been told the roots will have reached. Once these trees are a bit larger, I will likely do that again.
when is the best time to fertilize a dwarf peach tree ??
Silveraggie on May 8, 2016
BEST ANSWER: Peaches like good fertilizer and respond well to good stuff. Watch the color of the leaves. I like to use it every 2 weeks to keep the color a good green and not a light color.
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: //
Can this be used on grape vines ?
Bulldog on Jun 12, 2017
BEST ANSWER: Yes it can be applied to grape Vines
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.
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.

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!
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
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.
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:
Should Tree Prep fertilizer be used if tree is planted in the autumn?
HollyB on Sep 1, 2017

Is this product for newly planted fruit trees?

meant to improve the soil so the trees can pick up the nutrients. It is not a harsh chemical fertilizer.

When do I fertilize this spring?
Robin R on Mar 31, 2019
BEST ANSWER: If you live in an area where the ground freezes, wait until it is fully thawed.
We just fertilized our trees and like to do so before they begin to bloom.
The roots are always active but it seems to us that fertilizing now gives the trees a nice start and the results are evident in healthy blooms and leaves. Hope this helps.

Doug M on Feb 12, 2019

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!

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.

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.

Good Product
We have been using TrePep for several years with favorable results. We will continue to use it now living in a different state.

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.
