Hi. I’m very new to Bonsai. I have two plants that are one and a half year old, grown from seed. One is Pinus Aristata, the other is Jacaranda Mimisifolia. The Jacaranda is growing large and I feel I need to repot. I have two questions. Can I repot this time of year, and what soil should I use? My plants are indoors and I live in Houston, Texas. Thank you.
