I think a steady fertilization program is best. I don't know the numbers, but I would fertilize at least once a month. Regularity is the biggest thing to be sure of.

This is just my assumption. I'm no expert, but that's what I've done with my berries and so far it seems to be working fine.

Ann: The reason it hasn't been done is that there are many variables and most fruits under most conditions don't require a lot of fertilizer. In fact, too much fertilizer can be just as bad or worse than not enough. Too much nitrogen can lower fruit eating quality and cause excessive vegetative growth. In general, if your trees are as big as you want, have good foliage, and reasonable growth each yr; then they don't need more fertilizer. A soil test is always a good place to start but if you can read what your trees are telling you, then you don't need that.

Many people apply a good organic mulch and find they don't need much else. If you apply a chemical fertilizer then early spring and early fall are good times for application.

Yes: Soils vary in mineral content, even on the same property. You don't want to buy and apply fertilizers that will supply too much or not enough of what you need to improve results on your particular soil.

Check the USDA Cooperative Extension Service network covering your area for information about having your soil tested. I would try searching "maryland extension" to see if that leads to it.

Thank you so much for your help!! My trees and berries all look very happy right now...I just want to make sure they stay that way. I'll test my soil and add compost and watch my plants!
