Poinsettia Care

Amy Batog

As native grasses such as little bluestem (Schizachyrium scoparium and cvs., Zones 3–9) and prairie dropseed (Sporobolus heterolepis and cvs., Zones 3–9) increasingly gain traction in gardens, exotics such as miscanthus (Miscanthus sinensis and cvs., Zones 4–9) are losing favor because of their invasive tendencies. But not all exotic grasses are troublesome and need to be avoided. Feather reed grass (Calamagrostis × acutiflora and cvs., Zones 5–9) is a natural hybrid of C. arundinacea and C. epigejos, which are both nonnatives and prolific self-sowers, but the hybrid rarely sets fertile seed—a major plus for an exotic grass, right? So why are other reed grasses—‘Karl Foerster’ aside—so underused? To answer that question is to understand the phenomenon of ‘Karl Foerster’ feather reed grass (C. × acutiflora ‘Karl Foerster’).

How to Grow and Care for Braeburn Apple Trees Malus x domestica ‘Braeburn’

This species of plants originate in central China. The closely related species R. molle japonicum come from Japan. Both these deciduous varieties are relatives of the popular Ghent and Knapp Hill hybrids.

Windowsill orchids are a houseplant favourite and I repeat and update some tips given 3 years ago.

Nothing says Christmas more than a poinsettia (Euphorbia pulcherrima). Did you know that December 12th is known as National Poinsettia Day? Plant breeders have developed a wide range of colors in hues of white, purple, orange, and pink, but red poinsettias continue to be the most traditional color of the holiday season.

This North American native plant is a relative of the popular holiday poinsettia. Both plants are members of the euphorbia family. This plant is sometimes grown for the colorful green and orange bracts, but it is considered a weed.

Icon of the southwest, organ pipe cactus (Stenocereus thurberi) is one of the best known species of cacti in the United States.Reaching up to 26 feet in height and 12 feet wide, this slow

IF YOU ARE STILL USING any synthetic chemicals on your lawn, I hope you will stop. So does Paul Tukey. When he founded SafeLawns in 2006, Paul says, “It didn’t occur to people that their lawns could be dangerous.”“The sad reality is that we know that a lot of the chemicals used to grow the lawn (the fertilizers), or the chemicals used to control weeds or insects or fungal diseases—all  of these chemicals are designed to kill things, and they can make us very sick, and they make the water very sick, and the soil very sick, and the air very unhealthy.”Giving up chemicals doesn’t mean you have to pave over your front yard.“We will have lawns long after all these chemicals are banned in the United States, as they have been banned in Canada,” says Paul—explaining that more than 80 percent of Canadians cannot use weed and feed products, or glyphosate (the active ingredient in Roundup herbicide) because they are

Tip Number 2: CHRISTMAS CACTUS is another story altogether. I grew one plant for more than 20 years, a family hand-me-down, that only perished after literally falling apart because it got so big and brittle and I had to move it, sadly, which did it in.The plant’s requirements are simple: Though its name says “cactus,” this isn’t some desert creature inclined toward basking in blazing sun, but rather a tropical forest native and an epiphyte at that (a plant that in its native habitat doesn’t grow in soil at all but nested in trees). Bright indirect light is fine; full sun will burn its tissue, which sometimes reddens up first, as if slightly sunburned, like it’s trying to warn you you’re getting close to the danger zone.No drafty spots for Schlumbergera up against a winter window, nor any radiators (what plant really likes either condition?). It can withstand temperatures in the 40s, if need be, but not the violent blasts of hot and cold, hot and cold.

HOW ARE WE DOING in the effort to reduce tick encounters and the diseases that ticks carry and transmit to humans? The results from a multi-year study in Dutchess County, N.Y., one of the areas of the United States with the highest rates of Lyme disease, shed some light on that question.
