However, some common problems that they may face include:Aphids: These small, soft-bodied insects can suck the sap from the leaves and cause stunted growth and distortion. Control them with insecticidal soap or neem oil.Spider Mites: These tiny, spider-like pests can cause yellowing and stippling of the leaves. Control them with insecticidal soap or horticultural oil.Fungal Leaf Spot: This disease causes circular, brown or black spots on the leaves. Control it by removing infected leaves and applying a fungicide.

Habitat
