My monkey gross is looking bad on the ends. The ends are yellowish brown with brown spots. It is this way in several beds. Any thoughts as to what the problem could be?
Most likely it either needs fertilizer or it is getting too much water.
How do I get rid of weeds that grow in my monkey grass?
Your best bet would be to hand pull as much as you can and then add mulch to keep weed growth to a minimum. However, you could also try sprinkling corn meal in the area, which has a chemical in it that acts as a pre-emergent on plant seeds preventing them from germinating. Sprinkling corn meal will not harm plants but will keep weeds from growing.
A friend gave me some Monkey grass this week. I have already planted it around my trees. I am wondering if I can cut it back to come out new this year since she gave me untrimmed plants. I don't want to kill them.
Yes, you can cut it back to within 3 inches without harming the plant. In fact, this will actually help with its regrowth. Here is an article that you may also find helpful: https://www.gardeningknowhow.com/ornamental/groundcover/monkey-grass/pruning-monkey-grass.htm
