I am trying to introduce native wildflowers to a west facing hillside that is currently just pasture grass and weeds. I am pulling out the blackberries and thistles but don't plan to do anything with the grass. I have a conglomeration of seed - a couple canisters of western wildflower seed, some crimson clover, and numerous containers of seed I've gathered this past summer/fall. I plan to just mix them all together and scatter them on top of the existing grass.
Two springs ago, we did have the hill down to bare dirt and I scattered a lot of seed at that time, but relatively few of them actually came up - likely because I didn't water it regularly.
Any thoughts on fall versus spring?
