Organic Gardening How To | Soil Temperature
Knowing your soil temperature is an important organic gardening how to before you plant your vegetable gardens. Your soils temperature is one key factor related to seed germination. Other factors include soil moisture and exposure to light.
If you plant your seeds too early when the soil is too cool, the seeds will germinate too slowly and will likely create a plant with a weak root system. I know that spring has just arrived and we are all anxious to get our gardens started, but it’s important to consider what you’re going to plant. Different vegetables germinate best in different soil temperatures.
Kale, radish, lettuce, pea, and spinach are considered cold-weather plants and germinate best when the soil temperature is slightly above 40 degrees Fahrenheit. To test your soils temperature, insert a soil thermometer into the ground to a depth of about three inches. Allow the thermometer to remain there for about one minute to get an accurate reading.
Cool-weather plants include carrots, broccoli, cauliflower, cabbage, onions, leeks, and beans. These plants germinate best when the soil temperature is 60 degrees Fahrenheit or above.
Corn, tomatoes, peppers, squash and cucumbers are warm-weather plants. They like warm soil and warm air and germinate best when the soil temperature is 70 degrees Fahrenheit or above.
Don’t germinate your plants indoors and place them in the outdoor soil too soon. Placing plants in soil that is too cool for them will shock them and stunt their growth.
Another organic gardening how to is to keep in mind that you can help to increase you soil’s temperature by covering your garden area with black plastic before you plant your seeds. The black plastic will absorb the sun’s warmth and help to heat the soil beneath it.
One last thing to remember and to be cautious about is frost. Your soil may have reached the desired temperature level for seed germination, but don’t plant your seeds if you might still expect frost. Frost may kill your young plants. You can check with the National Climatic Weather Center to help you find when the last chance of frost is for your area.
Yes, spring is here and we’re all anxious to get started. I hope this organic gardening how to will help you grow a terrific organic garden.
