Dracaena marginata bicolour |
Dracaena marginata bicolour leaf - closeup |
I took the above photographs outside as it is a warm day and I wanted to repot the plant as it was outgrowing it's pot. It's now safely indoors.
From what I can gather, the temperature required for Dracaena marginata is ideally 15C minimum and 29C maximum. I think that's about 65-85F - do check for yourselves (external link). They like to be in plenty of humus or peaty soil but grow slowly and only require repotting every 24 months or so. They enjoy bright morning or late afternoon light or mid-shade and grow to a height of about 5ft or 60 inches. If they grow too tall you can simply cut them down and they will throw out stems from around the cut; the same applies to side shoots.
On the down side, they can be prone to insect attack - blight, mealy bugs - but I will deal with that if it happens. You are looking for a PH level of about 6 - 6.5
Allow them to dry somewhat between waterings, use tepid water, and avoid water with fluoride. I propose to try and collect rain water.
