The weather this week was very rainy and stormy, with a just few hours of sun.
Until now, the vole which burrowed in the soil and damaged the stems of all three plants, did not came back, after I refilled the tunnels with compost and set up a rodent repeller.
Nevertheless, my neighbors informed me that despite setting up a rodent repeller too, some of their herbs were completely destroyed last night. Maybe I have to think about further ways to protect my plants so they wont get damaged again in the next days.
I believe because of the recent stress, all three plants are now showing some little preflowers. The good thing is, that all flowers are actually female.
