I’ve had my juniper bonsai for over a year and it hasn’t grown. It sits the same window with about 8 hours of bright indirect light daily. It’s next to a heat register, and I water it from the top and in the saucer beneath. The leaves started to brown on the end of the branches, so I trimmed the brown bits and changed the soil to bonsai soil about a week ago and made sure the roots had plenty of room to grow in the soil. But now the ends are starting to brown again. Any advice/ideas as to why the tips are browning and it’s not growing?
