Last spring I spread white and red clover seed. I had tons of clover plants and a lot of red clover blooming towards the end of summer. The white clover should go nuts next summer. I'll be spreading more seed in the spring.
We broadcast white dutch clover seed on roughly five acres of mowed lawn, trails and paths, including the perimeters of our many gardens. Seeded/planted/scattered when its raining lightly has worked out very well for us. The original planting was more than 20 years ago and we just planted some more 2 years ago. Cost to plant 5 acres was $120.00. Planted 5 acres of Buckwheat that same year for under $60.00 if memory serves but it takes some care (tilling, watering) hence we only plant occasionally.
Clover, being a tough perennial that spreads through its roots and seeds can survive many years under the right soil and growing conditions, and just gets more prolific with each passing year. If you don't mind a lawn filled with clover flowers its better than grass IMO. It does a great job of keeping quack grass at bay and blooms most of the summer once started. I just mow it when about half the flower heads have begun browning. Mowing at that point then seems to rejuvenate rapid growth, blooming and spreading. With this method I've convinced my wife that the lawn doesn't need mowing every week anymore :) a win, win, win considering the benefits also provided to our bees.
Dandelions are by far a favorite and we let them flourish making our lawn areas quite the site when in full bloom. An added bonus is that the dandelions don't seem to interfere with the progress and proliferation of the white clover and both keep quack from taking over. About the time the dandelions finish up the clover begins blooming.
Alas, Our mowed yard and paths are more likely to produce a bee sting than any of our hives :laugh:. Flip flops are worn at your own risk.
Oh, almost forgot. Plant CHIVES every where. We have about 15 Apple trees and all are surrounded by chives that we just let go. Our Bees, our Apples and Us all benefit from chives. Bees love them!
