Q: Do you have any advice on the best soil composition for a bonsai tree indoors?

A: Several “tree-like” indoor plants can be trained to have the classic bonsai look. Jade plant, ficus and Norfolk Island pine are prime candidates. As such, they don’t need anything more complicated than commercial potting soil. But one factor to keep in mind is that your plants will be growing in the same container for several years. As time passes, the soil will become compacted and resistant to water passing freely through it. Make a note on you calendar to repot your indoor bonsai with new soil every couple of years.
