OK , so I planted mine , several years ago , in the ground and in the wrong spot , I looked at commercial plantation pictures and they were in full sun , so that’s what I did . I had a few fruits after 5 - 6 years . Flowered last year but no fruit , the 1.70 meter tree looked like it was gonna die , branches dried ...Now it is back to normal but so far this year no flowering . I’ll give it some Epsom salt.
Should I maybe put some shade cloth over it ?
Thank you Luke for this great Info .
well, those pictures are deceiving. What you'll find when you visit a commercial operation (I have) is that they're never put in full, baking sun--they are planted at an aspect which gives them gentle sun exposure, and the pictures that show the sun beaming down on them have been taken at a time during the day when that is happening. But they aren't ever exposed to that kind of heat all day. They can't handle it. Look at don's pictures in the fingerlime thread in the discussion boards--that's their precise natural conditions.
4 hours of gentle light is perfect if you can manage it, on either side of morning and dusk.
They are hard to get fruiting in the ground--well, prolifically anyway. You're much better off keeping them in a large pot filled with a gritty mix. Try to keep your PH around 4-4.5. I have tried a bunch of different fertilisers, cheap citrus granulated stuff is good, the best I've tried ( and still use) is a nutrient mix designed to work in coir, but it is expensive. I can't stress enough how important light, free draining soil is.
