I read the article on potting in the FAQ. Very interesting, but I am looking for some information more specific to my scenario. If this has already been addressed in another post, I apologize for the redundancy and would appreciate a nudge in the right direction.
This March, I took some cuttings from the old family fig tree, originally brought from Sicily in 1942. After a few months of struggles, I now have 9 thriving trees about three feet tall each. Most of these will be planted in the ground on my own property, but I want to gift a couple of them to my sisters. They both live in Orange County, California within a mile or two of the beach (no frost). They don't have room to put them in the ground, so I bought some large terra cotta pots - about 36" diameter.
1) The pots are unglazed; Should I seal them?
2) What type of soil should I use? My property has beautiful decomposed granite. I was considering just mixing some of my soil with compost, vermiculite and perlite.
3) Should I use some sort of reservoir and/or filler tube?
Any other suggestions would be appreciated. These trees are of great sentimental value to myself and my family. So, I want to prepare them to them in a way that will give them the best chance of success considering that neither of them are into gardening or growing things.
