How to Clone Plants: Turning One Plant Into Ten

Cloning is just taking cuttings, and it's the cheapest way to multiply a garden. This is exactly how I propagate the cuttings I sell — what works, what kills cuttings, and how to do it for free.

A cutting is a piece of a plant that grows roots and becomes a whole new plant — genetically identical to the parent. It's not complicated, it's not new, and it's how gardeners have shared plants over the fence for centuries. It's also how I produce most of the rooted cuttings I mail out. Once you can clone, you stop buying plants you already own.

What clones well (and what doesn't)

Soft-stemmed herbs and houseplants are the easiest entry point. Woody plants are slower but doable. Things grown from a single taproot — carrots, most trees from seed — don't clone from stem cuttings.

The four ways to root a cutting

  1. Water rooting — stick the cutting in a jar of water on a windowsill. Easiest for mint, pothos, basil. Change the water every few days.
  2. Soil/medium rooting — stick it in moist perlite or a light mix under a humidity dome. Stronger roots, better for the long haul.
  3. Division — for clumping plants, just pull the root ball apart into pieces, each with roots and growth. Instant new plants.
  4. Layering — bend a low branch to the ground, bury a section, and let it root before you cut it free. Great for woody plants that resist cuttings.

My exact cutting method

1

Pick the right stem

Take 4–6 inches of healthy new growth, not old woody wood and not the soft tip. Cut just below a node — the little bump where leaves attach. That's where roots form.

2

Strip the bottom

Remove leaves from the lower half. Too many leaves and the cutting loses water faster than it can drink; too few and it can't photosynthesize.

3

Dip in hormone

Dip the cut end in rooting hormone powder. It's optional for easy plants, a big help for woody ones.

4

Stick and cover

Push into moist perlite, firm gently, cover with a clear dome or a cut soda bottle to hold humidity. Bright indirect light, never direct sun — you'll cook it.

5

Wait and check

Roots come in one to three weeks depending on the plant. Tug gently; resistance means roots. Then pot up into soil.

Jordan’s tipThe number one killer of cuttings isn't lack of water — it's too much. Soggy medium rots the stem before it can root. Moist, not wet. If you can squeeze water out of the medium, it's too wet.

Why I prefer cuttings over seed for some plants

A cutting is a clone, so it's true to the parent — same flavor, same color, same vigor. Seed can vary. If I've got a basil plant with perfect flavor or a tomato that shrugged off our heat, I clone it rather than gamble on its seed. It's also faster: a rooted cutting is weeks ahead of a seedling. That head start is part of why mailed cuttings establish so well.

Every plant in your garden is a potential ten. That's the whole secret to a cheap, abundant garden.
