Question -
I bought a couple of large yukka trees from an auction in july, and until a couple of months ago they were fine, now the lower leaves are very droopy and turned a very pale green, mostly yellow and I think they are dying.  I pulled the dead leaves off originally, but if I keep doing that I will have no plant left.  Could it be due to the central heating?  The plants are by the window and I water them when they dry out,about twice a week.  I hope you can help as I love these trees, and they don't look well.
thankyou

Shelley,

How tall are your yucca plants?  What direction does the window face ? How often do you water them? Let me know and I will answer your questions.

One is about 7 foot, and the other about 3 foot.  one is facing north and one is facing south, i water them twice a week, when they do not have any water left.  

Answer
Shelley,

These are dessert plants. They like sun and dry. Stop watering immediately and do not water for at least 2 weeks then only water when the soil feeels bone dry and the plant is light weight. In the summer they can go outdoors but need to go into a semi shady location so they don't get sunburned. Pull off the lower withered leaves and if they get plenty of sun they will grow more new green leaves. Good luck.
