Question
Hi,  I have 2 of thes for 3 years -  in a bonsai pot.  Had a problem with fungus gnats and finally transplanted both.
One is doing fine (although I still see some fungus gnats.
The other lost about 1/2 of its leaves. What should I do?
Thanks


Answer
Betty,

You should be watering these like cacti and they should be planted in very sandy cactus soil. Water them, an hour later empty the drain tray under them and do not water them again until they have been dry for at least 5 days. The pot they are in should be no larger than twice the diameter of the bulb. In other words if the bulb is 3 inches across the pot should be no more than 6 inches across. I suspcet you have them in too large of pots and in standard potting soil and you are giving them too much water so the roots are rotting and that is attracting the fungus gnats. Carefully move them to smaller pots and use sandy soil then put them in the sunniest location possible. In the summer put them outdoors in full sun on your patio table and they will be very happy. They love being root bound. They love dry. During the winter I only water mine every 2 weeks, in the summer once a week.  Good luck.
