Re: What tropical fruits can I root cuttings of?
Not familiar with all of these. I have grown lychee from seed. With citrus, grafting is probably the most desireable method, as you can use the rootstock that is best suited to the particular situation. Using Poncirus trifoliata as a rootstock will give you a dwarf tree. There are also cold tolerant, and nematode resistant rootstocks, etc. However, they can be rooted from cuttings and, with the use of rooting hormones, they're not too difficult. Most of the ones sold in airport gift shops, and other touristy places, are rooted cuttings.
