How To Combat Common Problems When Growing Sage For A Healthy, Happy Plant

A resilient and aromatic herb loved by gardeners for its culinary and medicinal uses,  Sage (Salvia officinalis), although a hardy plant, can run into trouble. If your sage is looking like it's seen better days, don't despair. Many of its most common problems have simple fixes, and with a bit of care, you can bring your sage back to life.

One of the first signs of trouble is yellowing leaves. This can often be traced back to overwatering or poor soil drainage. Sage is a Mediterranean herb whose roots prefer a dry, well-drained environment. If your plant looks soggy and sad, check the soil. If it feels damp, cut back on watering and ensure the pot or garden bed has proper drainage. Another culprit could be root rot, which is caused by waterlogged conditions. If root rot sets in, you might need to remove the plant from its soil, trim away the damaged roots, and replant it in fresh, airy soil.

Another issue gardeners face is powdery mildew, a white, dusty fungus that often strikes when air circulation is poor. Sage does best in sunny, open areas with plenty of room for its leaves to breathe. Avoid crowding your plants; always water them at the base to keep the foliage dry. Get rid of powdery mildew in your garden by treating the leaves with a natural fungicide like a neem oil spray or a homemade mix of baking soda and water. Pruning any affected leaves can also help prevent the spread.

Pests are another challenge for sage growers, with aphids, spider mites, and slugs being frequent troublemakers. These tiny invaders can sap your plant's vitality, leaving it wilted and stunted. To keep pesky aphids and spider mites off your plants, a gentle spray of water or an insecticidal soap can work wonders. There are kitchen scraps that can rid your garden of snails and slugs, like eggshells or nutshells. You can also wrap copper tape or mesh around the base of your plant, as the slugs and snails don't like the static electricity it gives off.

Sometimes, sage can grow tall and leggy, especially if it's not getting enough sunlight. Sage loves full sun, so ensure it's planted in a spot that gets at least six hours of sunlight a day. If your plant is stretching out too much, a good pruning can encourage bushier growth. Trim each stem of the crown back by a third, avoiding new growth. Regular pruning not only keeps sage compact but also helps to stimulate new growth.
