Pls can you identify the plant in the photo

Question

Two of these plants were planted outside in the garden. In March we got a gardener in who advised that these plants can grow successfully inside the house. He planted them for us in two new pots with fertiliser and an effective drainage system. He advised that we should water with 1 litre of water once per week. Well I did that for the first week but a lot of the water drained right through. So I sunctioned it out as I did not want the roots to rot. From there on I watered with just 500ml per week. One is doing reasonably well, however the other developed mould in the centre. I have since moved it outside and removed all the mouldy leaves. Please can you advise how I should proceed from now on. Should they be inside or outside? How much do I water them and also identify the plant for me, so that I can do my own research. Your assistance is greatly appreciated.

Answer 1

You're correct that the plants should not be overwatered. However, what's happening in the center of your plant may be due to a fungus. I would repot the plant in a clean pot with fresh potting soil. A treatment of neem oil or insecticidal soap will help, as well. Here's an article that will help you decide how to treat your ailing plant:

The plant may be from the dracaena or diffenbachia family, but the leaf shape and trunk don't match up exactly. If this is a native plant in your region, your local garden center or agricultural service can help you identify it more precisely.
