Chrysanthemums are among the so-called heavy consumers and have a high water and nutrient requirement. The substrate should not dry out, but autumn flowers do not like feet that are too wet either.

Water at intervals
Plants rarely die from drought, more often because inexperienced gardeners have literally watered them to death. This even applies to such thirsty specimens as the chrysanthemum, which, if possible, should not be allowed to dry out. Therefore, make sure that the plant is in well-drained soil that allows excess irrigation water to drain away. In addition, overwatering can be avoided by watering at intervals. It is better to give smaller quantities several times in a row than one large gush. You can easily determine whether the plant still needs water by doing a finger test.
tips and tricks
Chrysanthemums, especially when they are cultivated in pots, often need additional watering even after a rain shower. Due to the dense growth, rainwater cannot always reach the root area, which is why it then remains dry.
