Gardening is a gamble in many ways. You need the right weather and you need to have good timing when you plant your crops. If the weather is good and you plant your crops at the right time you will have a good crop.
Tilling or working up the soil is very important to have a good crop. Sometimes it can be hard to know when to work up your soil. The sooner you can work up your soil the sooner you can plant and the sooner you will get a crop. But if you work up the soil too soon the dirt may be too cold, too wet or too dry for the seeds you plant.
You need to wait until the frost is out of the soil before you till it up. Once the frost is out you need to wait until the soil is dry enough to work it up properly. Soil that is too wet will be clumpy when you work it up. Clumpy wet soil is not the ideal planting soil.
When trying to determine if your soil is ready to work up take a handful and squeeze it in your hand. If it feels like mud it is obviously too wet to work up. If it is somewhat crumbly when you squeeze it then it is idea to work up your soil and plant it with seeds. If the soil is dry you can work it up but it may be hard to do. Dry soil can be hard for a tiller to bite into and it can be hard to dig up with a shovel.
Soil that is too dry can be worked up and planted with seeds. When you are done planting the seeds you need to give the garden space that you planted a good watering. You will need to keep your garden moist after you plant the seeds until the seeds sprout and grow into hardy plants. Then you will still need to keep your garden properly moist so your plants will grow the best they can and give good produce.
It is always a good idea to work up the soil in the fall after you have harvested all the vegetables. When winter comes and the snow melts the water from the melt can soak into the garden space easier then if you do not work up your garden in the fall.
