From one plant to many — growing cuttings on a windowsill

You do not need a greenhouse to grow plants from cuttings. A bright windowsill, a clear cover for humidity, and a little patience turn a single stem into a whole shelf of new plants. This guide keeps it practical: what to cut, what to root it in, and how to tell whether it is working.

We focus on the plants most people actually keep — pelargoniums, coleus, petunias, herbs and easy houseplants — and on the cheap, low-tech methods that root them reliably without special equipment.
