Fertilizer for Potted Geraniums

Geraniums are most often in pots about 12″ to 16″ (30-40 centimeters) in diameter. In this case, it is advisable to fertilize potted geraniums in the spring-summer season. In addition, there will come a time when there will be no need to repot geraniums since they are relatively small plants and won’t develop long roots.

As for the fertilizer, for potted geraniums, we can choose between a solid and liquid fertilizer. The ideal is to start applying fertilizer at the beginning of spring, although it can also be done throughout the summer, with a frequency of once a month. These are some types of fertilizers recommended for potted geraniums:

  • Organic fertilizers. Any can be used for geraniums: compost, humus, green manure, guano, manure…. Just pour a handful per plant and mix it with some more soil.
  • Fertilizers (chemical fertilizers). They are used to make geraniums bloom. It is recommended to use one per plant, and that it is, above all, specific for geraniums. It is important to always read well the label of each fertilizer to know how many doses to apply.

Fertilizing potted geraniums is very important for proper care of potted geraniums and flowering. For years, we’ve relied on a 15-15-15 NPK fertilizer for our geraniums, consistently yielding excellent results.

How to Prune Geraniums

Geraniums tolerate pruning well. You should cut back branches at any time of the year to fix their shape. Cutting off the end of a branch will cause it to send outside shoots and form more stems and more flowers.

In late winter or early spring, you should prune your potted geraniums almost to the ground when the plants have no vegetative growth. This is a good way to rejuvenate old potted geraniums or try to save plants affected by the geranium butterfly.

Most Common Potted Geraniums Pests and Diseases

Some pests can affect potted geraniums quite badly:

African butterfly (also geranium borer). These insects are usually found in warmer seasons, with an average temperature of about 68 °F (20 °C). The main problem of this butterfly is that its invasion is silent. Indeed, it does not cause direct damage, but, if it deposits its eggs, caterpillars may appear and affect the stems. In this case, the first thing to do is to remove the damaged and invaded parts of the geranium and apply a specific insecticide. A trick: to prevent the appearance of these pests is to use preventive insecticides, to take care of geraniums.

Geranium whitefly: these insects damage the leaves with their bites (very visible due to the intense greenness of geranium leaves). Another way to detect this pest is if the underside of the leaves has white cottony dots, which are the larvae of the whitefly. They can be removed by hand or using neem oil, which is organic.

Spider mite: this pest feeds on the sap of geranium leaves, which produces small yellow spots, causing the leaf to curl and then dry out. To avoid this pest, it is best to apply an insecticide during the colder months.

Geranium rust: this disease causes yellow spots to appear on the leaves, similar to pustules. These, after 15 days, burst, releasing a series of spores that eventually kill the plant. To prevent it, use a fungicide and get rid of the plant before the pustules open to avoid affecting other geranium bushes.

Leaf spot: With this disease, you will see watery, blister-like spots on the older leaves of your geranium that spread across the leaves. To solve it, remove the infected leaves and apply a chemical treatment with fungicides.

Gray rot (botrytis): this fungus appears in conditions of excessive humidity. You will notice it if the tissues begin to soften with gray and bluish spots. To treat it, apply a fungicide.
