Common sorrel: when to prune it?

In May–July: cut off the flower stems as soon as they appear and cut the plant back in summer for new leaves.

What else to prune in those months? May · June · July

Cut flower stems off at the base, before the flowers open.
After a heavy harvest or in July, cut all the leaves back to 5 cm above the ground; fresh, tender leaves regrow.
Remove yellowed or damaged leaves throughout the season.
In February–March you can clear away last year’s dead leaves.

Common sorrel flowers in May–July, when it attracts butterflies.
If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
As a native plant, it feeds more insects than a non-native species.

Caution: Sorrel contains oxalic acid: use it in moderation in the kitchen. If you leave the flower stems, the plant seeds itself freely.
