Even better!
Would you be able to prune the house? I don't know the layout of your place, but that might make more room. Otherwise, the neighbour's land is always an option.
That's awesome. Please post back with an update on how it goes! Would you ever get fruit from the mulberries, or do the birds eat them all where you are?
Yes, convert that lawn! Two plants worth considering are Prunus persica 'Kernechter vom Vorgebirge' and Amelanchier × lamarckii. I've heard great things about them, but they were growing in SW Germany, so do your own research first. What do you use for a ground cover? Clover can be a valuable ally in the fight against the grass.
That is an impressive agroforestry system. :) Which chestnut species do you grow?
You have a ton of potential in South Florida! (Until sea level rise floods everything, of course.) Will you add more fruit trees? The nurseries in your area have some amazing options. Which mangos and avocados do you grow? I'm curious about the quality of 'Monroe' and 'Oro Negro' avocados.
It's strange what's happening with your avocados. Do you know if the bloom timing of avocados in your area has changed at all? If they were previously getting pollinated by trees that now bloom at different times, then that could explain the lack of fruits.
If it's a choice between banana and grass, I recommend banana 100%. Pine Island and Excalibur both sold Dwarf Namwah last I checked, and that should be very productive. Excalibur also sells FHIA-18, which doesn't taste so much like banana. I recently posted about it here, though the linked PDF is in spanish.
Off to a good start! Do you know what else you want to add? Forelle pear might be worth considering for your area, but do your own research.
Sounds like you've got a great thing going! Maintaining fertility by mulching with cut vegetation and composting "waste" is really important. How big is your fruit forest? Do you plan to diversify further and fill up the field? How small do you plan to keep the trees? I've found that pruning tall trees with a pole saw is really tedious and exhausting. Do you have a particular method that's easier?
Nature is a horrible place, but every animal deserves to be free. Perhaps it's the concept of freedom that people have trouble accepting. Until someone manages to design an improved version that functions without hunger and disease and predation, natural forests are still the superior habitat.
Yeah, I hate when the temperature falls below 18 degrees Celsius! There have been times when I've gotten so uncomfortable that I've had to put some pants on. It's possible to survive it, for sure, but it sucks.
Is there no chestnut blight in your area?
