Protecting your Salvia Divinorum plants

Protecting your Salvia Divinorum plants

Aphids, slugs, caterpillars, thrips, spider mites, and scale insects can also damage your Salvia Divinorum plants. Root-rot and stem-rot can be problems. Fungal spots can appear on leaves. It is not known which plant viruses attack Salvia Divinorum, but probably some do, as many attack other sages. Aphids and scale insects can be removed with a cotton swab dipped in isopropyl (rubbing) alcohol. Slug damage can be reduced by growing Salvia in pots on a raised deck or palette. Some may still get by and attack your Salvia Divinorum plants. Keep an eye out for these slimy pests. One slug can eat an awful lot of Salvia! Beer can be used to attract and drown slugs. Set a saucer of beer in a slight depression in the ground; the surface of the saucer should be flush with the soil, so slugs can get in, get drunk, and drown. Spider mites can be controlled by dissolving Castile soap in water and spraying the leaves, including the underside. Repeat at two-week intervals for three applications. Caution: there have been some reports of soap damaging leaves, so don't use too much. Your garden hose is your best friend in fighting most outdoor pests. Spray the leaves hard enough to blow the pests away, but not hard enough to damage the leaves. Don't forget to spray the underside of the leaves too. A fine mist nozzle works best for this.

Propagating Salvia Divinorum plants

Salvia Divinorum is usually propagated by cuttings, not by seed. Cuttings may be rooted either in water or directly in soil. Here's how:

Rooting Salvia Divinorum in water

Cut off a branch (4-8 inches long) bearing some leaves. Cut off the leaves that are attached to the lowest node on your cutting then immediately place it in about one and a half inches of water in a small water glass. Only one cutting is to be put in each glass, so if rot develops in one cutting it cannot spread to another. It is best if the cutting is cut back to just below a node, since nodes are the places from which new roots are most likely to develop. While it is not necessary to make the cut here, doing so has the advantage that there will be no stem material dangling in the water below the node. This is important as the cut stem end is more likely to start to rot than is a node. Make sure the cutting is made with clean shears, or a knife, so the cut stem does not get attacked by germs and fungi that could cause stem rot. Place it where it will get some filtered sunlight. Change the water daily. It may be a good idea to use cooled boiled water. If your water is chlorinated, boiling will drive off chlorine. Non chlorinated water may be contaminated with plant disease germs, but boiling should kill these. Rooting in water is successful about 75% of the time (the rest of the time stem rot occurs and kills the cutting). In two weeks roots will start to develop. When they are about 1/2-1 inch long, transplant to potting soil in a well drained pot. Cover with a clear glass jar or clear plastic bag to serve as a humidity tent until the Salvia Divinorum plant establishes its roots in the soil and appears vigorous (usually 1-2 weeks). Then gradually wean the Salvia Divinorum plant from dependence on the humidity tent.

Rooting Salvia Divinorum in soil

Salvia can be rooted directly in soil. Materials needed:

• Potting soil.
• Two disposable plastic cups.
• Some Rootone® powder (this is a rooting hormone mixture that also contains a fungicide) it is available at any nursery.
• A 1-gallon thin, transparent polyethylene food storage bag.
• A rubber band.
• Water.

Punch some small holes in one of the cups for drainage. Fill the cup 2/3 the way up with potting soil. Using a pencil or a finger make a hole in the soil about 2 inches deep. The soil is now ready for your cutting. You must now prepare the cutting. With clean shears, cut off a length of stem from a healthy Salvia Divinorum plant. Leave a few leaves (small ones) on top. Harvest the larger leaves from the cut-off stem. Immediately after cutting the stem, place it in clean water. Cut it back to just below a node, as roots will develop from the node. Keep the cut surface wet. Place the cut surface, and the stem for about 1 inch above the cut, into the rooting powder. Shake off the excess. Rooting powder is somewhat toxic, so wash your hands after handling it. Place the powder coated cutting in the hole in the soil. Gently push the soil around the cutting, holding it in place while filling in the hole. Water the planted cutting until some water runs out the drainage holes. Place the cup with the Salvia Divinorum plant in it into the second plastic cup (which is there to catch any runoff water). You may want to put a small piece of wood or plastic in the bottom of the outer cup to act as a spacer. This allows enough space for excess water to drain. Place a 1 gallon clear plastic bag over the rooted cutting, using a rubber band to hold it in place. The rubber band should be outside the bag and the bag outside both cups. The Rubber band holds the bag against the cups. As the plastic bag acts to conserve moisture, frequent watering is not required. After several weeks you can transplant the now rooted Salvia Divinorum plant to a larger pot.
