Speaking of all the things you have to keep track of. Since I have a couple greenhouses now I have been trying to grow some tropical plants. We live in Zone8 and the greenhouse gives us a +1 zone. So with a little extra heat in the winter I hope I can keep them alive throughout the winter. I have some Mango, Avocados, Lemon and Lime trees.
As far as pollination goes, I just found out that my single apple tree hasn’t’ been producing because I need a “Pollinator” tree, of a different variety planted semi close to it. I’m glad I found out about that since I was thinking of chopping it down.
And the Tropical plants have very specific Pollination techniques. you should look up Avocado Pollination, they have male and female flowers but they open at different times of the day Morning and Afternoon, so to get the best results you have to have another Tree which has the male and female flowers that open at opposite times of the other tree. A/B vs B/A. Lots to learn.
I learned about apple tree pollination when we planted a wee orchard. LOTS of reading and thinking went into picking those trees! I also wanted baking apples and apples that would store well. So I got 3 different varieties. And a self-pollinating almond and 2 hazelnut trees. I can’t remember now, but the pear, peach, and apricot must be self-pollinating...I only got one each of those.
If they all produce, I will be overwhelmed, LOL!
We had lemon, orange, and avocado trees in CA - and just got lucky because they were all highly productive. But we only had one of each, so a neighbor must’ve had some. Lucky you - it is SO nice to have fresh lemons! Our lasted throughout the winter - I would just go pick one when I wanted it. And avocados are so expensive! Funny thing about those - we had a possum living with us for a while, and get got fat on avocados until we found out he was living in the shed!
