My wife acquired a hay bale from our gardener on Saturday and on Monday began to spread it around the tomato growing grounds in the back yard.
We like hay spread around the grounds around the tomato plants and elsewhere. Hay keeps the ground temperate and more moist. And over time it just degrades into the soil. The only downside we've found is that cutworms like the environment under the hay as well.
My wife watered all the tomato plants yesterday. She spent about five hours yesterday spreading hay and watering.
