How to Start It
★ Recommended for beginners
Yellow sweet clover handles frost, so sow it about 4 weeks before your last spring frost, or in late summer. Scatter the seeds over raked soil, rake them in about 1 cm deep and water. They sprout in 3 to 7 days. Rubbing the seeds lightly between two sheets of sandpaper first helps the hard ones sprout.
Yellow sweet clover is grown to feed the soil and the bees: its deep roots break up hard ground and add nitrogen (a plant food). It is not a low lawn clover but grows into tall, bushy plants, and it can spread into wild places, so cut it down before it drops seed.

Growing Tips
- 1Grow yellow sweet clover in full sun.
- 2It grows in poor, dry soil, even soil with lime in it, and needs no compost.
- 3Water only until the seedlings are growing well.
- 4Skip feeding, since its roots make their own plant food.
- 5Cut the plants down when the first yellow flowers open, before seed forms, and leave the stems on the soil as mulch or dig them in to feed the next crop.
- 6Pests rarely bother it, and bees love its honey-scented flowers.

How to Harvest
- 1Cut yellow sweet clover when the first flowers open, using shears or a string trimmer.
- 2Chop the stems into short pieces and leave them on the soil as mulch, or dig them into the top of the bed.
- 3Wait about 2 to 3 weeks before sowing or planting into that soil, so the stems can break down.
- 4If you leave some to flower for the bees, cut it down before the flowers fade and seeds form.
Step 5
Saving Seeds
How to Save Seeds
Yellow sweet clover usually flowers and makes seed in its second summer, then dies. Bees carry its pollen, but it does not cross with your garden plants. Let a small patch flower and wait until most of the tiny pods turn brown, then cut the stems into a paper bag and let them dry for a week. Rub the pods to free the small yellow seeds and store them labelled in a cool, dark, dry place, where the hard seeds keep for many years. Cut down every other plant before it seeds, since dropped seed can come up for years.
