I received 2 baby guava plants recently and planted them in my backyard, they had roots and everything, very healthy, they come from Cuba. One is doing great, but the other one the leaves are drying up and I don't know what to do because I am watering it good and it gets plenty of sunlight. Here is the healthy one http://i149.photobucket.com/albums/s49/locoboy0712/DSC002842.jpg
and here is the sick one vvv
Maybe root rot.
Is the plant well drained?
Yes it is, it's garden soil mixed with sand.
Check for tunnels around the roots, air can dry it up, and voles/moles may be hungry, but tamp and ck the roots are IN soil.
