Thanks everyone for your comments.
Regarding the burying process. There really isn't too much to it. I will post pictures for you in the next month or so when I bury my trees.
This is what I do: I've dug a hole - 8' long, 4'wide and 3' deep. Keep in mind that the initial digging of the hole is somewhat labor intensive so you need some good friends and a case of beer to make it easier on your back. But once dug, I use the same plywood to cover it for the summer. I've also put a piece of astro turf on top to protect the wood and for it to be pleasing to the eye....otherwise my wife wouldn't be happy.
I have supported the sides with large cement patio stones, which I secured with rebar to keep them in place, so that it doesn't collapse. After the leaves fall off the trees, I prune them to fit the hole. I will tie up the large tree with rope to fit the width of the hole. I dig out one side of the fig tree, under the root ball so that I can bring the tree down. It's almost like a hinge. (In the spring, I replenish this dirt to support the tree) Since I have another tree on the other end of the hole, I put the larger tree down first, and then the smaller one on top. I then cover the hole completely with a 4x8 sheet of 3/4" plywood. I then use a plastic pool cover, looks like a huge bubble wrapper, to cover the plywood. I then shovel dirt all along the edges of the plastic cover to ensure a good seal. I don't get carried away with the dirt around the edges...just ensure that it's a good seal.(Only cuz I have to dig it all up in the spring!) My tree is over 20 years old and I've trimmed it year after year, but it's still a VERY large tree. Because of this, and also the fact that I'm not a spring chicken any longer, I use a come-along ratchet lever to bring it up every spring. Now some of you are probably saying..."Wow! this is way too much work!" but in reality, it takes me 2 hours in the spring and 2 hours in the fall....and I do it by myself. In the end...I have a beautiful tree with great figs...which I love! And I'm sure you know....there's nothing like walking up to your fig tree, first thing in the morning and enjoying fresh figs for breakfast!
The main crop usually ripens about 70 - 85% depending on the summer. This summer has been very unusual for us and hardly any of the main crop has ripened. The weather the next few weeks should be what we expected during the month of August so we'll see how many of them ripen.
Regards!
