Radicchio is a wonderful early spring or fall green that is easy to plant in the garden. Below are the simple steps one will need to follow to grow the best radicchio that you can.
The first step in this process is to prepare the garden space. Radicchio likes a well-drained soil in a sunny location. Once the garden space has been found, the next step is to increase the soil’s fertility. The easiest way to do this is to add well-seasoned compost. There is not a clear cut amount that you need to add but you will need to incorporate it to a depth of 5 to 6 inches. This can be done with a garden fork or a tiller.
After the compost has been incorporated into the garden space, the next step is to make your rows. Radicchio likes to have 24 inches of space between rows. The easiest way to make these rows is by either drawing lines in the soil or running a string from one end of the garden to the other. Utilizing the latter approach will help you plant in a straight line.
Since the seed of this plant is small, the easiest approach is to sprinkle the seed along the rows that you have created in the soil. Top the seed with ¼ inch of soil. At this point, you will need to water but do not just pull out the garden hose. You will need to simply mist the soil and in doing so you will need to attach the sprinkling attachment to the gardening hose before watering. Once that is done, gently water the soil. Keep the soil evenly moist until the seeds begin to germinate.
This green should germinate in about a week. After the seeds have germinated, keep the soil evenly wet. Once the seedlings have reached 1 inch in height, the next step is to thin them out.
Radicchio likes to have some space, which means you will need to space the seedlings so that they are 8 to 15 inches apart.
The last step in this process is mulching. The mulch itself is simply straw and should be placed around the thinned out seedlings. While the mulch will conserve moisture, it also helps control weeds and keeps the roots of the green cool.
To produce the best radicchio, continue to monitor the soil moisture and water often but do not water deep.
