I have a random question! Maybe someone who has a little bit more experience with growing trees could help. I have a friend who has Excelsa cedars, and they are wondering what the best way to fertilize them would be (they are mulched and in pots). They want them to grow really well, and I honestly don’t know too much about growing trees. I told them manure might be the way to go, but if anyone has any tips at all, that would be great. They want to use them as a hedge eventually once they are big and strong enough!

Thanks!

little late for the answering party but; compost/manure can be a good way to go, though in general slow-release granular fertilizers will do (in spring/summer though, not now or in autumn it’d just cause them stress).

There’s evergreen specialized fertilizers sold but I think in general you could get away with any standard granular fertilizer so long as its a 50-50-50 balance blend imo.

Also if they become rootbound at any point of their development before planting they should have their roots cut/pruned, as all the kinks in the roots will do is slow development/health of well beyond their establishment phase.
