Another way I let loose is to get my hands dirty in the garden. I haven't done very much permanent gardening at my current house because I rent. However, I did get outside this afternoon and plant some garlic and onions. I get really ambitious once spring fever sets in so I have to be careful that I don't plant more than I can take care of. It doesn't help that I am gone to Washington 5 weeks out of the summer and come back to the excruciating heat of late July or August.
The backyardgardener has some nice tips on what can be done in our specific USDA plant hardiness zone, central Oklahoma is 7a (from the National Arboretum).
