to grow chard is one of the most easiest things. you almost have to do nothing. you just have to sow the seeds in spring with a distance between the rows and in the rows of about 40 cm, to thin out the young plants, defend the chard against slugs and wait.
the young thinned out chard plants are delicious in a mixed green salad, so you don´t have to chuck them away.
the chard is growing so fast, that you don´t have to care about weeds normally.
and here is how to cook a delicious chard and feta cheese tarte flambée.
