I am going to try some new things with our lawn this year. The yard is a mix of dry hot sunny areas and deep shade. The soil gets compacted very fast. I'm thinking of aerating and sodding the backyard, which is mostly deep shade and the grass gradually peters out there a few years after sodding. I resod every 3-4 years and seed spring and fall the 2nd and 3rd years.
For the front yard, which is sunny and the grass does pretty well, I'd like to try over seeding with Dutch White clover. I read the clover will supply 1/3 of the nitrogen needs of the grass. And the bees will like the flowers. Dutch White is a low growing 1-6 inch clover. I am looking forward to trying this.
Interesting - if you google "lawn clover" the first entry is how to grow clover in the lawn, the second is how to get rid of it ....
