I bought a crown of thorns plant from a plant sale 3 weeks ago for $2. It was in sad shape when I got it, even though it is over a foot tall and densely branched. Most of its leaves had fallen off. The woman who sold it to me said it had been over watered, so not to water it for a few weeks. It still has very few leaves, though there is some new growth and a few new leaves have grown at the top of the plant.
Should I water it now? How often does it need to be watered and how much? Nowhere it my house gets much direct sunlight-- will that be a problem? Is there anything else I can do for it to make it perk up? Thanks.
