How I Root Cuttings in Sand

I used to overthink this. Special seed-starting mix, humidity domes, the whole production. Then I started sticking cuttings in a cheap bag of coarse sand, and honestly, more of them lived.

Sand sounds wrong if you grew up being told plants want rich soil. That's the point. A cutting doesn't need lunch yet. It needs air around the stem and water that doesn't sit there and rot it. Sand does both.

Get the right sand

Coarse sand. The stuff that still has a little grit and tiny pebbles in it. Builder's sand, paver sand, silica sand, even pool filter sand if that's what the hardware store has.

Skip the play-sand bag. That stuff packs down like wet flour and holds water. You'll come back to mushy stems and a smell you don't want in the kitchen.

How I actually do it

Nothing fancy. A pot or tub with real drainage holes, sand at least five inches deep so the cutting can sit without falling over.

• Cut a piece about four to six inches long. Longer than that and the top wants more water than the stem can pull.

• Strip the lower leaves. Leave a couple up top so it can still make food. Too many leaves and it wilts before it ever roots.

• If you can't stick it right away, keep it cool and recut the end before it goes in. A dried-over cut is lazy about growing roots.

• Poke a hole with a pencil if you're using rooting hormone, so you don't rub it all off on the way in. Then firm the sand back around the stem. It should stand up on its own.

• Keep the sand moist, not swampy. If water is pooling in the saucer, you're overdoing it.

Bright light helps. All-day sun is fine for a lot of outdoor stuff if you can keep them from drying out. On a windowsill, bright and a little sheltered is enough. I don't baby them with a plastic bag unless the house is desert-dry.

How long, and how you know

Soft stuff like coleus or basil can show roots in a couple weeks in warm weather. Roses, figs, rosemary, and hardwood cuttings take longer. Sometimes a month. Sometimes more if you started them in the cold.

Give it a gentle tug. If it tugs back, it's working. Don't yank it out every other day to check. That's how you start over.

When it is rooted, pot it into real soil. Sand got it started. It will not feed it forever, and that's fine. You weren't asking it to.

When it goes wrong

Brown, slimy stems usually mean it stayed too wet or the sand was too fine. Wilting with dry sand means you walked away for too long. A cutting that never moves might be the wrong plant for the season, or you let the cut sit around and seal over.

I still lose some. That's the deal. Sand is cheap, though, and you can stick a whole pot full at once. One tray in summer and suddenly you have more basil than anyone asked for.

If you've been buying starter plants every spring, try this once with something easy. Coleus. A piece of pothos. A rosemary tip. The first time a cutting you stuck in a bucket of sand shrugs and starts growing, you get why people get hooked.
