How to Plant Seeds Outdoors Make a sketch of the garden area. Draw in roughly where you want to plant each type of seed. The seed packet will tell you whether sun or shade is required for each plant you grow. Most plants flowers and vegetables grow best in sun. Choose a sunny area where the soil drains well after a rain.
Full sun means an area that receives sunshine all day, without shadows falling over it.
In spring, wait until the soil has dried enough so that a clump of soil pressed in your palm falls apart when you release your fingers. This is called the clump test. If you dig in soil that is still too wet and sticky, it can damage the soil structure and cause growing problems for your plants. So wait the soil will be a little warmer, too, which is good for the seeds. The soil test will tell you whether any nutrients or adjustments are required, and how much to add.
