Thank you, dr.dawg, I will get a heater w/ an automatic thermostat. I have used dormant oil before on all my fruit trees so I guess I will also use it on my citrus trees.
I have another question n may you or someone else can help. Last spring my ponderosa lemon n Meyer lemon bloomed, but they're in a lanai covered w/ a screen so I tried to pollinate them manually but the Meyer lemon lost all its booms,while the ponderosa lemon kept most of its booms n I do have 3 huge lemons that survived the very hot weather this year. My question is this: r some citrus plants self pollinating ? Is the ponderosa lemon one of them? Thank you!
