If you want free plants by summer, March is your moment. As light levels rise and sap begins to stir, a select group of shrubs and perennials are perfectly primed for propagation – quick to root, eager to grow, and ready to bulk up borders, pots, and back yard beds before the heat of high summer slows everything down. Miss this window and you will wait another year.
The trick is knowing which plants respond best right now and taking cuttings before they harden off or flower too heavily. With a sharp pair of pruners, fresh potting mix, and a little patience, you can turn one plant into many and fill gaps in your yard for nothing more than the price of compost.
