Transvaal daisy

Robert geranium should be watered when the top inch of soil feels dry to the touch. Water gently, being careful not to get the leaves wet. It’s best to apply water to individual plants and near the base of the stem. Avoid overhead sprinklers. Avoid watering during the hottest times of the day. Water deeply, providing enough so that water runs out the bottom of the pot. A good rule of thumb is to water about 1 inch of water per week. Water less in the winter when the plant slows down its growth.

Robert geranium (Geranium robertianum) thrives in full sunlight. It should be placed in a location where the plants receive at least 5-6 hours of direct sunlight each day. In areas with hotter temperatures, however, Robert geranium can do well in part sun or partial shade as long as it receives at least 3 hours of direct sunlight daily. Watering needs are minimal as Robert geranium prefers the soil to dry out between waterings. When watering, ensure to thoroughly water the soil around the base of the plant.

Robert geraniums should be pruned lightly in mid- to late spring. These plants are quite hardy and can handle a moderate amount of pruning. Start by removing any dead or diseased stems. Then, soften the shape of the plant by pruning back a few of the longest stems by 1-third of their length. This will help keep the plant shape and reduce any legginess. After that, lightly trim off any tips of stems that appear damaged. Finally, pinch off any leggy flowers. Pruning Robert geraniums too heavily can damage the delicate blooms or result in the plant not producing flowers.
