In my garden, this is the time to plant Swiss chard. It grows slowly in summer heat and gets a new lease on life in the fall, which is when I start eating it. It goes dormant for the winter, and then in spring it emerges again and gradually progresses to making enormous leaves over a foot long. These early spring leaves are very thick and meaty, and have a taste that has the umami elements of meat, but is mild and clean. These early spring leaves are the ones that I eat, in huge quantities. They are great cooked, and this is the only time of year that I love chard as a salad green. As soon as the plant starts to bolt to seed, the leaves of the elongating stalk acquire a rather dreadful dirty taste. Interestingly, the large thick leaves at the base retain their mild delicious flavor for a while, so once the central stalk starts to form, you still have a week or two to collect leaves. Then the chard season is over, and in my yard the rest is cut and goes to the goat. When the last chard plant has been cut, I know it is time to plant more for the following fall and spring. ‘
So plan ahead, plant now, and love your chard in its best season.
