4. Warmth and Sunlight
When it comes to growing asparagus it is important to make sure that you plant your crop in an area that gets plenty of sunlight. They will need at least six to eight hours of sunlight every day.
The plants need this much full sunlight each day in order to grow well. If the asparagus is in the shade too much they may not grow as well as they should. Asparagus is a warm-weather plant, which means that they do best in soil that is warm.
You can increase their growth by laying some black plastic over the garden soil several weeks before you are planning to transplant your seedlings. This will help to keep the ground warm and will lead to much better growth. You can also mulch around the asparagus with some dark compost, which will help to heat the ground more and keep the soil around the plants at the temperature that they desire.
