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
Is this product natural ?
Marcia P on May 4, 2016
BEST ANSWER: It looks like blue koolaid so I doubt it. But it probably depends on your definition of natural. I also use manure and that is definitely natural.
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.
I am looking for an organic fertilizer to use on Apple trees at planting, any suggestions?
Joanna G on Apr 1, 2016
BEST ANSWER: Put whole uncooked baking potatoes in the bottom of the hole before planting. As the potatoes decompose, they slowly release potassium and nitrogen. It acts as a slow-release fertilizer. Be sure they are deep, under the tree, otherwise, they will sprout.
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.
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
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

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.

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.

Just started using it as I have just planted six young trees. Seems to be working just fine as my trees are blooming and new growth is starting. No sign of transplant shock has shown up.

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!
