Can some one tell me why the leaves are turning black and what i could do to help stop it?Also if you know what the second plant is can you tell me?Thank you!

Answer 1

Take the leaves with spots off. Are you letting the jade plant dry out a bit between waterings? You should be.

Answer 2

That looks like either a fungus or a mold.  Take a specimen to your local county extension office (local university) and they will be better to tell you.

Take a jade leaf and stick it in a different pot (your soil may be contaminated) and soon a new plant will grow.  This way you save a part of the ailing plant for now.

Answer 3

The second plant is a hoya

You are watering too much, they thrive on neglect

Answer 4

gosh I think what you have here are two kinds of jade plants.  one green and one variegated.

if you have been growing these plants a long time and this is a sudden problem I would suspect insect attack.  maybe mites or something tiny.

disease is also a possibility.   I find I have lots of problems with succulents if I overwater them.  

one other thing could be sunburn if you have just gotten them or just moved them to a sunnier spot.

it is pretty hard to tell from your photos, I am afraid.

Answer 5

it appears to be either too much water or too little water - take one leaf to the local garden store or florist shop- they will be able to tell u whether u have something serious like mold or fungus on the plants.  good luck
