We are now into the New Year and by the time this reaches your mailbox we will be only weeks away from the next growing season. Early March is the typical last frost so Valentine’s Day is the earliest best time to trim plants. Bush roses can be cut back by about half but do not trim climbing roses until they have bloomed.

You may have noticed a white, cotton-like growth on neighborhood nopales the past few months. This is caused by a parasitic scale insect called cochineal (Dactylopius coccus) – but don’t be alarmed! Normally the insects do not harm the nopales. The cochineal lives its life sucking on the pads of prickly pear cacti, producing carminic acid, which, when mixed with aluminum or calcium salts makes carmine dye, also known as cochineal.

This deep rich color and its resistance to fading made cochineal one of the Americas’ most important exports.
