Victoria plum tree
I've recently bought a young Victoria plum tree, and I plan to plant it into large pot. I've read around online on appropriate application of fertilizers for newly-potted plums, and so far I am still unclear.
I plan to plant using a multi-purpose compost that already has a pre-added 4 month feed that I purchased. Is that a bad idea? Some posts I have read said you should avoid fertilizing at an early stage as it risks foliage overgrowth and stunt the fruit/flower development and to consider a 10-10-10 (high potash) fertilizer only in March-ish.
So what is the best thing to do?
