I would check your adult plant that are shedding their leaves to see if it is caused by insects and also the soil that they are in. If you have not changed the soil for quite sometime, it may need to be replenished.
Are you wanting to take cuttings from your older plants to use for cuttings?
Using you seedlings for grafting and if so, how old are they?
The best time to do any grafting is when they are in active growth. Also, timing it so that once you have made the grafts that you will still have good weather for further growth. In the West Indies I would imagine that you would.
