Frost Damaged Citrus-Best Way to Fix
I've had an improved Meyer Lemon in the ground for almost a year. I planted it just before fall last year. Even though I covered it, it lost its leaves in the frosts. It hasn't started to leaf out yet, but the stems are green and mostly flexible.
I was really worried that it wasn't recovering, so I dug it up and put it in fresh soil in a 15 gal black plastic pot. I'm going to keep in indoors at night and put it out in the sun during the day. I still get frost on the ground in certain spots in my yard.
Is there anything in particular I should do to help it leaf out and recover from what I think is frost damage? Fertilizer? Nitrogen? Any and all suggestions are welcome. I don't want to buy another lemon tree.
