You can grow the tree indoors/greenhouse. It will be a valuable tree once your graft takes. Most online nurseries sell what they claim to be a true seedless finger avocado tree for $100 if you're lucky to find it. This is my find of a lifetime as far as avocado varieties goes. Also, second place would be the Hawaiian Russel avocado tree I have. Once I verify the size of that Russell fruit, then I will be sharing scions maybe next year..
Greenhouse isn't an option, but I could try indoors. Having this fruiting in my living room would be lovely.
No tree to graft onto currently though. :\ Would be up for getting one that's pre-grafted unless more scions are available later, but I may get a store-bought seed going to graft onto myself.
Does this one have more of a dwarfing habit or is it full size?
