Title: No blooms on Spineless Prickly Pear in Austin
Answered by: Mike Tomme
QUESTION:
I've had a spineless prickly pear planted in the shade for about 3 years. It has done just fine there, but has never bloomed. I recently moved it to a full sun location(I'm in north Austin) and covered the soil with decomposed granite, and know that it is in a bit of a shock and is rerooting now. I'm wondering when it might finally bloom, and what I might do help it along - will it finally bloom on its own after moving to proper conditions? Thanks!ANSWER:
There are three things required to produce blooms on Opuntia ellisiana (Spineless prickly pear):
1. Good sun
2. Well drained soil
and
3. Patience.
You have already taken an important step in moving it to a full sun location.
I hope the soil you planted it in is well drained and doesn't contain too much organic matter. When people have trouble growing this plant, the cause is usually lack of sun or root rot caused by waterlogged soil. Full sun and well drained soil are generally all this plant needs to thrive in central Texas. The decomposed granite is also a good idea. The granite could be amended with a liltte (very little) compost.
Now the hard part - the patience. It has been this Mr. Smarty Plants experience that it takes several years after being established for this plant to bloom and the ones I see blooming around town are generally pretty large indicating they've been there a while. I suspect your cactus is just not mature enough to produce blooms. Give it time.
