I have the same "problem". I think it is due to lower than ideal humidity. I could be wrong, however.

If it reassures you, the same thing happens to coffee plants outside in the ground here in winter--many will have either lots of yellowed leaves or leaves with brown on them. Lack of humidity and cold will bring that on.

Yellow/tired leaves also happen in August if plant is in a lot of sun even with high humidity and ample water and good soil.

You must have been reading my mind. Last spring I got a heck of a coffee plant (actually about 6 seedlings in one pot) via mailorder. I kept em watered and with filtered sun. They were doing just fine! Now, they are doing what yours are doing (but no yellow leaves, just browning at the edges). I think it's because of low humidity where I am at. It even put out a little bit of new growth this winter! Hopefully when I re-pot in spring it'll come back. It's not dead, just not happy looking.

I agree, probably humidity and seasonal. Mine are have filtered sun in the afternoon. Full sun almost killed them! The humidity around her has picked up the last couple of weeks and they are looking great right now.

My coffee tree - a 5 year old, 7 ft high - has been having the same issue.

It was moved from a western exposure to full southern sun in August, and soon after wards it started developing buds, blooming, and now coffee pods are growing.

However, around the same time, I started seeing a lot of lower/inner leaf yellowing and drop-off. This tree has never had an issue with browning tips even though our water is heavily chlorinated and the humidity in here is around 50%.

It is growing well, has grown around 2.5 feet in the past 8 months, actually! I recently potted up and it was pretty root-bound. I checked for root-rot and everything looked healthy. There hasn't been a change in the number of yellowing leaves.

It is on a regular watering schedule and never gets too wet or too dry.

I think they should be looking like this one.

I wish! I took "Cherries" from this plant near Kona and have grown a few. They are now awakening from the winter blues. Mine dropped yellow leaves etc during the winter, though nearly always humid here.

How often should a large coffee plant be watered and how much water should be given? Should plant be in filtered light? When and how much fertilizer should be given and what type?
I have a large plant that has lost a lot of leaves. It is about 8+ feet tall. When should I be worried that it will not recover?

I keep the soil moist with sharp drainage. I give it filtered light. Normal fertilzer or 'natural' for flowers. Leaf drop is common as long as the plant stays warm and healthy. Humidity above 40% and when in my greenhouse ocillating fan.

I have a young coffee plant, and I am wondering if anyone suggests putting it outside during the warm months zone 7 or in a glass greenhouse or is it best to keep indoors all year?

I'm in zone 9, central Florida. My trees also have brown spot and I'm here to hopefully find out why. I can suggest some things I know about growing coffee. If you live in a colder climate and have to bring them inside, they should be in an eastern facing window. Coffee is an evergreen and should not yellow and drop leaves. Maybe the yellowing is caused by too much water with poor drainage. Whenever I transfer my trees to a bigger pot I always remove most of the soil around the roots, (being VERY careful not to damage the "tap root" then plant in new organic soil. This way they get the benefit of new minerals.

All the leafs are brown on my coffee bean plant is it dead or what should I do to help my coffee bean plant it is pretty small to medium size right now it's in a pot any help I can get would be appreciated

I'm in dfw Texas area I'm not sure which zone we are in

If it was outside in DFW in winter temps,its probably dead. If its dropping leaf indoors,it most likely went too dry. NEVER let them go dry in the home. One good dry out will kill even large Coffee plants grown as house plants.

Water and see if buds sprout. Time will tell.
