I have a coffee plant.

Yours will do best if you plant them in the ground, about 1-2 yards apart. 5 in one pot is way too many for their deep root systems.

I planted seedlings a few years ago. They were in too much shade,so a dug them up a few days ago. Sure enough,like Salevene said- it had thick deep roots. Yet,they don't take drought at all. Funny.

They don't like a prolonged drought, but the coffee plant is quite strong and can resist period of low rainfall.

i still have my coffee plants in a pot, leaves are growing, stem not so much, I made a mistake and put some acid type food on it, so far seems ok, but I hope I didn't harm it.
