There are three main seasons for planting in the Growing Dome. The time to begin planting is in the spring, round about mid March, when the soil is warm enough for the seeds of the warm weather plants to germinate.
To ensure proper germination, the soil needs to have an average temperature of 60 degrees Fahrenheit. This is the most important time to sow seeds for your summer crops for example: tomatoes, peppers, cucumbers, squash, beans, basil, and other heat loving crops.
The next period for sowing seeds in your dome is the middle of September. These are the seeds for your cool hardy, winter crops, which will keep you going throughout the winter. Some examples of these are: cabbage, broccoli, arugala, lettuce, leeks, onions, swiss chard, spinach carrots, beets etc.
At this time the summer crops are in full bloom, so it may seem as if you have limited room in the dome to grow. However, you will notice that most of the summer crops now have large foliage, higher up in the Growing Dome. This actually leaves bare patches of soil, where you could now sow the seeds. At this time, you sow the seeds of the winter root vegetables directly in the bare soil, as they do not transplant well, ie: turnips, beets, radishes, carrots, etc.
The leafy vegetables can be sown in flats, which could be located on the cross bar of the water tank if you need the extra room, or don’t have sufficient room for your flats. These seeds will be ready for transplanting to their final location, about mid October. This will ensure a timely supply of veggies all winter.
If you sow the seeds in November, when you pull out the summer crops, these plants would not be well enough established to give you winter veggies.
The third season of sowing is in February, and again you would want to sow a second round of cold weather seeds at this time. Generally speaking the winter greens are starting to go to seed in February and March so using this strategy you will be able to have continuous greens available until May or June. HAPPY GROWING!!!!
