Growing a Mango Tree

I have two tropical fruit trees a Mango and a Guava. They are still in pots. I have not planted them in the ground yet. I am waiting for at least 60 degrees at night.

I put them outside in daylight and bring into garage at night. I've wrapped the roots in black plastic to protect from a cold snap. Because it still goes down to 40 degrees at night here I use a plant light at night. I may have put too much Miracle Gro on them. The leaves are dying even though the stem is still green.

Hardiness Zone: 9a
