Prickly Pear Cactus

I have a prickly pear that is about 15 years old. In all the time I have had it, it has only bloomed once. It was covered with hundreds of yellow flowers. What am I doing wrong? I have taken a piece of it and started a new one a few years ago. I keep that outside year round, I live in Zone 6. The original I bring in every fall along with my night blooming cactus.

Please help and thank you

It may not be getting enough cold in the winter. They need cold, dry winters to bloom and in the house, it may not be cool enough or kept dry enough.

I would check to see what the exact zones are for your variety of prickly pear cactus. It may be able to survive outside year round where you live. If this is the case, in the fall, move it to a sheltered location, like under an eve, where it will not get too much water from rain or snow.

How does one treat a diseased prickly pear cactus in Albuquerque (westside) New Mexico? Half the tunas have rotted/deteriorated over the winter.

It sounds like your cactus has rot. It is typically causes by too much water during dormant seasons but that normally causes rot at the base, so I think yours is caused by a fungus as the rot is higher. Treat the plant with a fungicide, and if possible, remove any rotted areas.

Propagating Prickly Pear Cactus

Should the pads be placed in soil or set out to dry without soil? Any more information would be appreciated.

After the initial cut it is recommended to let the cut section dry for a day or so, then place it cut side down in sandy potting soil.

Prickly Pear in Shade

We have a garden area in a courtyard in Arizona that never gets direct sun. I’d like to plant an opuntia because of shape and texture. Can it survive, even if it doesn’t grow much there?

Prickly Pear Cactus does need a dry, full sun location.

Will it survive? It likely would survive but not thrive.

I might suggest Agave victoria, Agave porryi or a Euphorbia.
These would be nice specimen plants that would thrive in a shade location.

Grass Invading Prickly Pear Cactus

I have a patch of prickly pear cactus which I really like. The problem is the grass grows up with it and you can’t see thy cactus. Is there something that would kill the grass, but not harm the cactus or could I gently sprinkle rocks in until the rocks kill out the grass? Perhaps you know another solution.

The "best" way to get rid of your unwanted grass largely depends on what type of grass it is. If you're not sure, try vinegar. This article will explain how: https://www.gardeningknowhow.com/plant-problems/weeds/how-to-kill-grass-naturally-kill-unwanted-grass-in-your-yard.htm
