I have had 2 red yuccas planted in my yard for about 2 years now. The 1st yucca was not in bloom when I purchased it and I planted it in the ground. It has grown new offsets, but has never bloomed. I live near Canyon Lake which is between San Antonio and Austin, Tx.

The second yucca was purchased last summer. It was in bloom when I purchased. I kept it in a pot for some time, then planted it next to the other yucca. When the bloom dried up, I cut it off. Is this a bad thing to do?

All of the other yuccas in the area are blooming like crazy. I have even seen yuccas blooming in the shade in New Braunfels! Is there anything special I need to do to get mine blooming?

Does yours receive at least a half day of afternoon sun? Hesperaloes bloom better in full sun, but my Mother's only receive half day afternoon sun and are doing great. Since yours are established plants, they do not need much water in your area. They are very drought tolerant. My Mother's have received no supplemetal water for the past 3 years. If there has been no rain, try watering them only when they start to turn more of a grayish-green than normal or look like they need water because they start to droop. In the winter, they usually do not need to be watered if it rains frequently. If it hasn't rained for a couple of months in the fall and winter, give them a deep drink. They do not need to be fertilized. If you do, fertilize lightly only in the spring. When they are overfertilized, they receive too much nitrogen which promotes leaf growth but not blooms. Perhaps the soil is too rich for them and they are putting out foliage and offsets without blooming. Also, the soil should be very well drained. Cutting off the bloom stalk is okay and it is recommeded if you do not want it to produce seeds. Remove the dead foliage at the base also if the plants have any. I hope that tis information has helped some.

Thanks for the info. I may have been watering too much, and although we just went through a dry spell (which ended in torrential rain Memorial Day weekend), we have experienced more rain than usual for our area throughout the past 2 years. I'll try to monitor the sun exposure as well. Thanks again for the info.

red yuccas also like to be in an alkaline soil, so maybe you should add some lime to the area around your yucca....Good luck!
