When watering zonal geraniums, soft water that is slightly acidic or neutral will have fewer minerals in them. Appropriate soft water includes things like lake, river, and rainwater. After storing the water for a day or two, certain minerals precipitate, and the water’s temperature will be closer to room temperature, making tap water suitable for watering the plants.


After autumn, maintain only three to five robust main branches that are evenly spaced and close to the base, depending on the growth of the zonal geranium. Remove the remaining weak and slender branches straight from the root.

On the branches, only robust lateral buds should remain; the others should be removed. After pruning, fresh, tidy branches will sprout and eventually bloom in about five days.

Apply Fertilizer

Fertilize zonal geranium plants once before they bloom, and then again when the blooms have withered. Granular fertilizer should be buried at the edge of the flowerpot and kept a suitable distance from the plants, whereas liquid fertilizer can be irrigated immediately. You can also apply fertilizer with a slow release.

After applying the fertilizer, track the growth for six to nine months.

Clean the soil after combining several culture medium, and then add the proper quantity of calcium superphosphate and organic fertilizer that has broken down. It is best to maintain the pH level at roughly 6.0. Water buildup should be prevented, and the soil should be damp but not completely dry.
