Just a couple of days a go my coffee plants leaves started to turn a brown colour. It is only the newest growth leaves that are truning brown, i just started to take them outside so that might be the problem or i watered to much and they still aren't drying up. This is happening on all of my coffee plants at different levels, here are some pics.

If you had them inside & just set them out in direct sun it is sunburn. When you move plants outside, they need to be aclimated slowly. Putting them in direct sun after being inside your house for a long period will burn the leaves. The next set that come out should be normal...

Yep, sunburn is exactly what I thought, too.

Coffee is a shade plant, so I would be careful about putting them out in full sun. SB

What could i use to make a shade cover for my coffee plants so they don't get sun burn.

Whether coffes is considered a shade plant depends on what country you are talking about. Colombia does grow coffee under partial shade of taller trees, but most other countries grow coffee in full sun. Dr. Malcolm Manners posted to this fact approximately 4 months ago. (I take from my notes)....."Dr. Manners said....." Partial shade is fine, but coffee will bear more in full sun........ Dr. Manners also posted "Colombia does tend to grow shaded coffee. However, Brazil (the world's leading producer) grows theirs in full sun. The trees are fine". .... Millet

k thanks

Yes, coffee trees will take full sun just fine; however, individual leaves which developed in the shade will not adapt to full sun. So I agree that the symptoms seen here are sunburn. As the tree makes new leaves, they'll be adapted to the brighter light. But then when you move the plant back indoors, those leaves will not be adapted to shade, and may quickly fall off. So it would be wise to avoid large changes in light level. Placing the plants under a shady tree or under the eaves of the house should help.

At least from my own experience it appears you have 2 different problems. The leaf scald is the lighter brown from sun burn. Those leaves will be shed, but the plant will recover. The bigger problem are the dark brown rotting away of the leaf. If you turn the plant out of the pot, you will likely see that the roots are also brown and starting too rot. As you guessed, it indicates too much water and the plants need to dry quickly. They really do prefer a well draining soil and they love Florida sand. But it's just my opinion.
