I started out gardening 30+ years ago and religiously used the Park's Seed germination chart. Then I found others and forgot about it. However, it is wonderful and I will now use it again.
Winter sowing makes things easier; but last year we had snow on the ground for 90 days right through the putting out for cold treatment. This
spring and summer I am using lights to start my perennials for next year.
I am just nuts about seeds.
