I am not sure if these are related:
- Two days ago it rained fiercely and at some point there was also hail.
- The basil plant had a neigbhour plant that had mealybugs.
- At the bottom of the stem, it appears some balls attached to the stem. I have no idea if these pests eggs. [
In addition, there is no snails in the vicinity of the plant. I checked the surrounding of the plant and there was no snails.
