Brown stalks on Swiss chard
I have a 10' row of Lucullus Swiss chard that have matured to about 24". I harvested very healthy and delicious older stems for several weeks when the stalks began to turn brown. All but two plants now have dark stems. I experimented with two plants and removed the affected leaves, but the plants may have been too severely pruned and are not producing new sprouts. Is there a way to save these plants going into fall? Is it safe to eat the brown stems? It is too late to replant? Thank you.
You need to be careful not to damage the terminal bud when harvesting.
