Geraniums will grow and flower best in full sun, but they require some attention now and then.
Here are some suggestions:
- Snip off spent and withered blooms (dead-heading). This will keep the plants clean and attractive and prevent formation of seeds, thus encouraging full development of new buds.
- Provide adequate moisture. Plants in the open ground, such as in massed beds, should be watered to a depth of 5" - 6" to foster deep root growth. Do this at regular intervals when soil is dry. Watering is best done early in the day - outside plants should not go into the evening hours and a dropping temperature with water on the leaves and blooms.
- Check moisture frequently in window boxes, hanging baskets and other container gardens which may need daily watering on excessively hot or windy days.
- Fertilize plants lightly when setting them out and again in mid-July. Apply the nutrients only when the soil is moist.
- If the plants become leggy, pinch out the tips or terminal buds to encourage better branching.
