What fertilizer do you you recommend for purple leaf plum trees

I think someone just asked this a week ago - and got an answer. Where do you live?

AWM has asked this question 3 times now. Don't like the answer? Don't know where to find the previous thread? Forgetful?

Well, let's be generous and answer again anyway - is this plum tree a baby in a pot, or a mature flowering plum tree in the ground?

For a potted plum, a soluble fertilizer might be the best way to go but a large tree in the ground should get any balanced, pelleted time-release fertilizer.
Something like Osmocote 14-14-14 would be fine. Depending where you are it may or may not last the whole growing season for you. Even though the package reads "lasts for 3 to 4 months" down here in the south it only lasts about 8 weeks because of heat, high humidity and heavy rain. So what fertilizer you use and how often you use it depends upon where you live.

Please would you complete your personal profile to let us know where (approx.) you live?

I suggested Ammonium Sulfate, the go-to for fruit farmers. Although Purple Leaf Plums are not "fruit" trees, blooms are still important. The rate is 1 cup per inch of trunk diameter sprinkled around the drip line and watered in. This is done in the early spring, early mid summer and early fall (too late in the season will cause growth that is destined to freeze off).

I never considered that this tree would be grown in a pot. But the measurements hold true for any size fruit tree in the ground.

Welcome to Garden.org, @AWM !

I hope you find your way back here and also find the above info helpful

Just out of curiosity how old is your tree? Many years ago I planted a purple leaf plum tree and shrub. The tree was a favorite for many years. Just stunning! It only lasted about 15 years or so though. Apparently they can be relatively short lived. The bush is still going strong.
