How To Apply Fertilizer On Geraniums

Fertilizing geraniums can be tricky because they require total attention. Geraniums cannot bloom well when over-fertilized. They benefit from slow-release fertilizer that ensures nitrogen leaching does not occur during heavy rains. 

Slow-release fertilizers further ensure steady nitrogen supply to the growing plants. The fertilizing method for indoor and outdoor geraniums is quite distinct, as shown below. 

Fertilizing Indoor Geraniums

Indoor grown geraniums require low fertilizer. Ideally, for new potted geraniums, fertilization is not essential for the first 2-3 months. Therefore, you should pot them in a nutrient-rich soil mix and do not add any fertilizer until the plant is established. Once established, they require fertilization approximately 4-6 weeks in spring and not more than 8 weeks during winter.

Fertilizing Outdoor Geraniums

Outdoor geraniums require completely dry fertilizers. You should apply dry fertilizer at a rate of 2 pounds per 100 square feet of soil, and they must be watered into the land.

Tips For Growing Geraniums

Sunlight provision

Geraniums are sun-loving, and they also love well-ventilated spaces. They should, however, not be exposed to full sun for long. You can leave them for 4-6 hours in the sun, especially during morning hours then give them light shade in the afternoon.

Avoid excess watering

Geraniums can survive longer in dry soil than where the soil is extremely wet. When you overwater them, they either die, or the leaves turn yellowish. Therefore, you should adjust how you water your geraniums depending on how the soil retains water.

Deadhead geraniums

Deadheading refers to the removal of the past blooms, usually by cutting off the bottom of the stem that sustains the flowers. You can also remove the yellow leaves to leave your plant in good shape. 

Protect from pests

Generally, geraniums may be attacked by pests. The most commons pests are caterpillars, aphids, and whiteflies. Apart from the caterpillars that may require you to purchase a pesticide, the other pests can be controlled by using homemade solutions.
