Where can I find more info online about planting lots of wildflower seed?”
One clear advantage of fall planting, particularly in cold areas, is that it gives you bloom earlier than spring-planted seed. For example, if you plant a mixture in, say October, you will see growth and bloom about 2-4 weeks earlier the following spring than if you had waited to plant your seed in May. In this respect, wildflower seed performs like grass seed; everyone knows a lawn seeded in fall is usually better established in spring than one seeded in spring. Your site may determine the time of year you plant. If it is a flat site, you can plant any time you like. If it’s at all steeply sloped, you should probably choose spring. This is because fall-planted seed is subject to “washouts”, since it has to lie there all through late fall and winter, while spring-planted seed has only to wait until it sprouts. The dangers to fall planting on a slope are obvious. If you decide to plant in fall, wait until after killing frost. The timing is roughly the same as when tulip bulbs are plante
