The first one is a clump of coffee plants, Coffea arabica, the plain old coffee beans you drink, planted and allow to grow into a green foliage plant.

It appears to me you've dried them out severely. They need constant moisture. They may recover with even watering, if not, they are easy to come by.

The second plant is Pan Am Pilea (P. cadierei 'Pan Am').

Thanks denninmi. The soil of the coffee plant is still moist, so I don't know if that's the problem, but I will try more water - deburn

Deburn, if the soil is still moist, don't add more water.

What size is the pot?
The soil looks soaked..is it?
Let the soil dry out, then water.
Another problem could be dry air. Shower/spray leaves once a day, without aiming at soil.

For now, what is pot size? Toni

Hi Toni, I did water the plant this morning :-(, so I guess the soil is soaked now. I've moved it closer to the window and will spray it tomorrow morning

The pot is 4" in size. It's the standard 1.98 plant from HD.

thanks,
deburn

Hi, the plant in the first two pics is still dying. Any suggestions would be most appreciated!

Deburn, your Coffee's leaves look dry. Are they crispy?
If they are, it's best removing them.
They need bright light, not full sun. Especially when young.
Spray or shower leaves daily. Water when soil feels/looks crumbly, not bone dry.
It took me years to conquer growing a coffee tree, they'd live less than a year then die. The one I have now is a little over five years..I left it outside, nights dropped in the 20's, and now my poor coffee looks terrible. Very few leaves are alive.
I hope yours makes it, Toni

Toni, the leaves of two stems were crispy, so I just removed them. I'll try the other things you mentioned, but it's not looking good!

Sorry to hear about your troubles - they are beautiful plants

Neither plant plant is getting enough light. The Pilea in particular has very elongated stems between the nodes, a sure sign of inadequate light. I suggest pruning back the stems to where the growth is more compact and then provide more light. New growth will be more compact, which is what you want with a Pilea.

The coffee plant appears to be in a pot that is too large and that means the soil is not drying out properly between waterings. Excess soil around the roots retains water for too long and causes root rot. Root rot symptoms often mimic excessive dryness symptoms because the roots are no longer absorbing water properly.

Thanks Will, I shall cut back the pilea and put the coffee in a smaller pot

Will, perhaps you didn't see Deburn's post..His Coffee is potted in a 4" pot.

Deburn, unless your Coffee's roots are extremely tiny, I'd keep in the 4" and let soil dry between waterings. Toni
