Q.Brown edges on leaves
I understand it is a watering issue but do I trim the brown edges off?
It's usually a good idea to remove any dead foliage from any plant, but you might want to remove them completely only if the leaves are entirely brown. If only the edges are brown, the leaf may still continue to grow and may even end up healing itself. Keep in mind that brown leaves are also part of some plants' life cycle, so depending on the plant, it really may or may not be a watering issue. It could also be due to the soil content.
