It’s just there for coolness factor. Note #2: Think saguaros won’t grow in New Mexico? Better think again! Check out my Dec. 2019 column, “ Here Today, Gone Saguaro ,” for the full story.

Thomas, Farmington Answer: While the right amount of water and really good drainage are probably the biggest hurdles for plant parents, once you get those figured out, optimal lighting and microclimate are the next major concerns. These seem simple, but they’re particularly tricky in the winter months when the sun sits lower in the sky, days are shorter, and heater vents emit dry warm air. A medium-light plant, like cyclamen, might flourish all summer

Question : I have a very large mulberry tree that offers great shade on the west side of my house in the summer. Last spring, I hired someone to cut back the limbs over the house and carport where they were dragging on the roof and the electrical line. There is an area of branches that are thick and will be hanging over the driveway by mid-summer this year. I have talked to a tree trimmer who is willing to do a minor trimming, but said that eventually I will need to cut the tree back significantly, down by about half. He said it will be healthy, leaf out, etc., and be better for the tree. He also said he would not cut it back once it begins to bud out. Does a mulberry tree this size need to be cut back by half now or in the future for its health or safety? I am thinking I may just not prune this year until I know more and

Photo credits Roger L. Question: Last October, we saw a beautiful plant blooming in an open lot in Corrales. Any ideas what it might be? The flowers in the second photo dry to become delicate triangular structures about 3/4 inch diameter in the last photo. I have a few seeds and am considering propagation. - Roger L., Corrales Answer: Firstly, thank you for taking the time to confirm that the plant you saw is one we want to grow in New Mexico before propagating it from the seeds you saved. Lots of weedy species have remarkably beautiful flowers—I’m looking at you field bindweed ( Convolvulus arvensis ) and puncturevine ( Tribulus terrestris , aka goatheads). We’d be in even bigger trouble if we started saving those s

Question: I’m wondering how to best care for the yerba mansa plants in my garden. After planting them in the spring, they took really well and looked healthy throughout the hot summer. Now the dried leaves and flower stalks are reddish-brown. Is it better to remove last year’s growth or leave it be?                                                 - Lin Y., Los Lunas Answer: I’m glad you asked because I have wondered the same thing, and I welcome the chance to learn more about this interesting plant. If you’re unfamiliar with yerba mansa ( Anemopsis californica ), this is a great opportunity to join the fan club. Here are some onboarding details for new fan club members: Famous for its medicinal properties, yerba mansa is endemic to western North America, from Oklahoma up to Oregon
