My trident maple bonsai went into dormancy entering winter. I repotted It, carefully removing some large roots and pruning for radial roots.
Bonsai soil mix of peat, leca, stone, bark. Extremely well draining. The pot is currently taking 4 days to dry out. Temperatures are 18-21 Celsius and not much wind. Its outside under a shade cloth area. I would say it's a little darker than it should be.
I pruned a few branches back.
After a few weeks, as I saw some life emerge, I fertilized with 5 3 1 and treated it with systemic as there were signs of aphids on my willows a few feet away.
Spring arrived and it pushed out leaves very quickly. However I have 30% of the leaves are curled and not flat and open. They have dark spots in the recesses of the leaves. Have I overwatered, fertilized or is there a known condition I could try treat? Also should I remove these leaves or leave them on the tree?
