Alyssum is a great plant for several different reasons. One reason is the fact that it is self seeding. What in the world does this mean? Well, what it means is after you plant it for the first time, it will come back without you lifting a finger.
The other reason I really like this plant is the fact that it blooms from spring to fall. This means less work for me but how do you plant alyssum?
While you can plant the seeds inside, I really like to just go ahead and plant them in their new home. To begin this process, I have to wait a little bit. What I mean by this is I have to wait until my local frost free date. Once that date has arrived and my soil has had time to warm, it is time to start planting.
To begin this process, one must first choose the location. Alyssum does best in a sunny, well-draining location but if you cannot find that do not worry. This plant can tolerate partial shade.
Now that you have your location selected, you will then need to prepare it. Remove any weeds from the area and loosen the soil. To aid the percolation rate of the soil, mix in a good amount of well-seasoned compost. Once that is done, smooth out the soil with a garden rake.
The next step is to begin planting the seeds. This can be done in two different ways. One way is to just open the seed packet and begin sprinkling the seeds on the ground. The second way requires you to pull out the ruler and lay it on the soil. This ruler will give you the measure by which you need to follow if you do not want to thin out your plants. The planting space for the seed is 4 inches. If you choose to just broadcast your seed, you will need to thin them once they reach 2 inches in height.
Regardless of which technique you pick, you will need to top your planted seed with 1/8 of soil and then mist with water.
In 8 to 10 days, you should see little green dots appear in the area by which you planted. Continue to monitor the soil moisture until the seedlings become established. After that, back off on the watering but do not let the soil get dry.
