Germination: Fill 4" pots with potting mix to within a 1/2-inch of the top and place a pair of seeds on top of the soil in each one near the center of the pot (having two is good insurance in case one doesn’t sprout. Pinch off the smaller, weaker of the two if they both sprout).

Cover them with a ¼-inch layer of soil mix and the compress the soil with your fingers. Good seed-to-soil contact is important for germination.

Sprinkle water on the seeds whenever the top of the soil mix appears dry. Don’t keep the soil soggy, however — the seeds may rot.
