Re: Re: HYB: long chill requirements?

I grew aphylla seeds by planting in the ground in late Oct. or just
before the ground froze. They always came up well in late May. But once
the ground freezes it stays frozen and snowcovered all winter, here. I
watered seedling rows during dry weather in spring until they emerged
and continued watering them if needed to get them established.

Aphyllas I tried grew well in gravely topsoil / clay subsoil. They
survive without cultivation for quite a few years competing with grass
in thin soils. I don't think aphyllas would survive on their own in rich
peaty clay soil at our new place. Grasses here grow 5' tall and would
overwhelm them.

The first time I grew an old local aphylla I treated it like a pet and
watered it all summer. It kept growing and blooming a little the entire
summer until frosts / late Sept. I never watered it again and it never
bloomed all summer again.

Aphyllas put on a good display here in late spring when cultivated. They
don't grow much in dry summer weather, don't flower much if left
uncultivated.
