Now is the Time to Sow Perennials
Seeds of most perennials, whether home-saved or purchased, is best sown as soon as possible after it ripens. Sow the seed in vermiculite or in a mixture of one-half sifted pentmoss and one-half sand. If you choose the latter, rub the peatmoss through a sieve made from wire screen and an old flat.
Measure off equal quantities of the sifted peatmoss and coarse builder’s sand, and mix them thoroughly – by hand if your quantity small (above, right) or with a shovel if you are going to use a lot. Place an inch or so of broken pots in the bottom of a seed pan for drainage and fill to within an inch of the top with the peatmoss-sand mixture and firm it gently.
Home-saved seed, if fairly coarse, can be placed in a paper trough and pushed out slowly with the index linger to insure even distribution over the surface or, if fine, place it in a small envelope and tap the envelope gently so that the seed pours out very slowly. Cover the seed to the proper depth, depending on its size, with the pentmoss-sand mixture; if the seed is extremely fine, however, it is safer not to cover it but to press it down with a small wood block.
Water the pans by letting them stand in water up to within an inch of the top until the surface is ‘Moist; then – sink them to the same depth in a cold-frame, where they should be kept moist, but not soaking wet, by very gentle overhead watering. Some seeds will germinate soon; when they have formed their second set of leaves they can be transplanted directly into the coldframe, where they will remain until next spring – thus giving them a jump on spring sown seed. Some, however, will lie dormant until next year.
