Growing

Easy to grow seeds
*You can direct sow straight into the soil outside after the frosts have done their worst….about mid May. This your seedlings to about a foot and a half apart.
*Or sow some earlier in modules….I sow some at the beginning of April….then plant them out six weeks later.
*Only lightly cover the seed…don’t sow too deep.
