The tree is growing, but there is no sign of fertilizer.

That’s better. The sooner I can start fertilizing, the stronger I can make the tree by decandling time.
I enjoy seeing the male flowers on pine, despite the mess. Here is the tree from the back and sides.
I usually start with 1-2 units of fertilizer for small sized trees and 3-4 units for larger trees. I treat young and middle-aged trees the same.

While it’s more common to hold off on fertilizing deciduous varieties to avoid long internodes and large leaves, I make some exceptions.
My plum is the first tree to show signs of growth each year, and if I don’t start feeding quickly, the leaves turn yellow.
Why mention fertilizer so early in the season? Because the sooner fertilizing begins, the more vigor can be produced in a given year. While this can be important for all varieties, it’s especially important for pines that are to be decandled as there’s only so much time between repotting and decandling.
I usually wait three weeks after repotting to begin fertilizing. My standard fertilizers are fish emulsion and cottonseed meal, but this year I’m planning to use a greater variety of fertilizers to ensure the trees get a broader variety of nutrients.
Is it time to start fertilizing in your garden?
