Dencil B on Jul 8, 2017
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.
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

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.

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 specializied 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: //
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
Can this be used on grape vines ?
Bulldog on Jun 12, 2017
BEST ANSWER: Yes it can be applied to grape Vines
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.
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 .

How do I use Tre Pep Fertilizer on my Chicago Hardy fig tree in an 8 cft. planter?
Thomas Buehler H on Apr 12, 2017
BEST ANSWER: Just follow the directions on the package and use it the same way you would as if the plant were in the ground. Be careful not to overfertilize and try to keep the container outdoors in warmer months so that it gets some natural rainfall vs. tap water.
How often do I use this for a new pear tree?
Justin S on Mar 28, 2017
BEST ANSWER: A soil test will be your first step to determining fertilization needs on trees growing there. Looking at the growth rate of your trees starting in spring is your second step. If the new growth develops at a rate that is less than 6 inches and you're well into the warm weather there, then you may want to fertilize. According to this product's label, you can use this fertilizer as frequently as every 10 days during the growing season (as needed).
star tre-pep fertilizer can I use it on my lemon,olive and fig trees?
elizabeth z on Mar 19, 2017
BEST ANSWER: A soil test will be your best guide for what nutrients to look for in the fertilizer you use. If you find that your trees are a little low on nitrogen and phosphates, then this is a great choice. Because this is a water-soluble fertilizer, it reaches the roots faster for trees growing in containers than granules/pellets.
I have 40 Lombardy hybrids that are 2 years old from bare root start, can I use the tree pep on them this spring?
jackson on Mar 2, 2017
BEST ANSWER: Absolutely. TrePep is a great all-around fertilizer for trees and plants.
Can the tree pep be used on citrus trees?
snowbird on Feb 16, 2017
BEST ANSWER: yes, treepep can be used on citrus trees
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 I use both the tree prep and the stark fertilizer?
Dallas C on Feb 13, 2017
BEST ANSWER: This fertilizer is ideal for getting new plantings established. You can continue to use it on more mature plants and trees as well. The Orchard Fertilizer is a nitrogen fertilizer, which is useful for mature trees that may require more vegetative growth to support a fruit crop. You could use both, but it is most likely not necessary. Let your soil test be your guide.
I have two mango trees and a mexican lime tree. Mango trees are about 5 years old and my mexican lime is about 6 months.

Do you recommend this product on these types of friit trees?

If so do I follow your standard feeding every 2 weeks from spring till july?
Romel on Feb 8, 2017
BEST ANSWER: This is a great all-around fertiilizer for all trees and plants, young an mature. Do follow the package directions for best results, and stop feeding at the beginning of July.

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!

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.

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.
