How to Cut and Multiply Sage Plants
Salvias, or sage, are beautiful late-flowering plants that make a great addition to any mixed border. Many are, however, tender, so it's a good idea to take cuttings as an insurance policy.
How to Take and Propagate Sage Cuttings
Cuttings are best taken in August or September. Here's how you do it.
- Collect your cutting material first thing in the morning. This is important as your plants will be best hydrated in the morning, giving you the best chance of success.
- Select a healthy stem, which is not flowering. Flowering stems are much less likely to strike than non-flowering ones. (If you have a particularly floriferous plant, this might be tricky!)
- Pop your cuttings in a plastic bag as you go around the garden; this will further help to trap the moisture in the stems.
- Bring your semi-ripe cuttings immediately back to your work area and prepare them.
- Aim for cuttings to be between two to three inches. From the tip of the stem, travel down on your cutting until you have reached about three inches. With a clean, sharp secateurs, snip just below the nearest of leaves. You may discard the portion of the stem below your cut. Remove the lower leaves from your cuttings, leaving a maximum of two each.
- Fill a 4-inch pot with a gritty potting mix. My mix has 40% to 50% horticultural sand in it, but you can use grit or perlite instead of horticultural sand.
- Dip each cutting in a rooting hormone mix and plunge it in your potting mix. Be careful not to damage the soft stems. A 4-inch pot can typically fit 5 to 8 cuttings.
- Water your cuttings once and cover them with a plastic bag. This will help trap moisture in.
- Keep your cuttings at room temperature, around 68˚F (20˚C), until they strike.
- Overwinter your cuttings frost free.
Next summer, you can expect lots of colorful salvias to brighten up your flower beds. Happy growing.
