47+ When To Repot Juniper Bonsai
Background. Younger bonsai should be repotted every three to five years. Chinese junipers are tolerant of tight root masses.
I'm starting with some indoors bonsai and will probably try some outdoors once i get some experience (and figure out an outdoors setup that offers the right amount of sun and shade). Once your japanese juniper is pruned, prepare its container. Repot the juniper bonsai approximately every two years or as needed.
It is best to move the bonsai outside in the spring after minimum night temperatures exceed 40ºf and return it indoors in the fall before the first hard frost.
Just when you think it's spring, it can be blizzarding and below zero. You can repot juniper any time during its growing season, but withhold fertilizer for 30 to 60 days afterward. Juniper bonsai trees flourish in full sun as long as the soil does not dry completely. For the majority of species, there it is well known (and is frequently referred to in the species guides at bonsai4me.com) that bonsai should be repotted 'when the buds start to extend', but, what exactly does this mean and exactly when does this happen?
