I have a few growing as novelty bonsai that are several years old. I overwinter under good lights & in humidity from 55 - 65% with no difficulties. Pests have never been a problem. I suspect that a cool & sunny window sill would be just the ticket. They don't particularly like to be kept dry, preferring an evenly moist soil with good drainage. Mine do very well in a very coarse bonsai mix, but I grow all my house plants in some variation of bonsai soil, usually with somewhere around a 1/3 organic componant & the rest of the ingredients inert. Never an overwatering or root rot issue that way. Fertilizer frequency depends on how fast your soil drains & how much water flows through the soil at each watering, but in your northern latitude, minimal amounts of fertilizer would be preferred as to much N will produce weak growth with long internodes that will spoil the appearance of the plant & need to be removed in spring anyway. Use foliage color as an indicator & fertilize with N only when leaf color showes the beginnings of yellowing. If you have access to a 0-10-10 fertilizer, it's a good choice for overwintering this plant.

If you'd like to see a picture of one as bonsai, send an e-mail. I'll do a little pruning on one & send a pic out this weekend.

Kristen, I also live in Wa. and over winter mine by cutting them back to around (6) inches and hanging them in my cooler greenhouse I water them sparingly thru the winter months,then in early spring i bring them into my warmer greenhouse and give them a good soaking,with Peters added to the water at 1/2 strength.And away they go again:)***Suzanne

I appreciate the feedback, thanks much! One last question, though - if I want to transplant these into different containers I assume they would prefer it done in spring rather than now?
