What should I do with my geraniums in winter?

Store your geraniums over winter Keep your geraniums in a cool, dry location, at about 50 to 60 degrees F. Check for mold about once a month and remove dried leaves from the bag or box. At the same time do a quick check of the stems — they should be firm. If you find shriveled, dried-out stems, throw them away.

How do you keep geraniums blooming in the winter?

Place the plants under fluorescent lights. Illuminated for 16 hours per day, I can tell you that zonal geraniums will bloom in winter almost as well as they do in summer. Once the plants are growing, I encourage bloom with a high-phosphorous, low-nitrogen plant food.

When should I fertilize my geraniums?

Fertilizing Your Geraniums You can feed your geranium once in spring, using a time-release fertilizer, or in spring and summer, using an all-purpose granular fertilizer. However, you won’t need to feed your plant at all for the first few weeks if the potting soil has fertilizer built-in.

What is the best fertilizer for geraniums?

The recommendation for constant feed fertilizing of geraniums is generally 200 to 250 ppm of nitrogen. Experience suggests nutrient problems are minimized when a constant fertilizer program is used. Fertilizer types: 15-15-15 (Geranium Special), 15-16-17 Peat-lite, and 20-10-20 Peat-lite.

Do you water geraniums in winter?

Geraniums will often survive a drought, but will not thrive. People growing show plants are careful to ensure their plants’ roots are moist but never wet during the winter. Ventilate as often as possible to keep the atmosphere around your plants dry.

What happens if you over fertilize geraniums?

Considerations. Geraniums planted in sandy soil require more frequent fertilization than geraniums planted in more organic-type soil. However, excessive fertilizer can result in decreased flowering. Fine tune your fertilization program based on your soil type and the overall health of your geraniums.

Do geraniums need fertiliser?

Healthy geraniums need regular fertilising. The best fertilisers are either a controlled-release fertiliser when planting or a water-soluble fertiliser every third time you water for a healthy plant.

Why are the leaves on my geranium turning yellow?

One of the most common causes of yellowing leaves is too much moisture or overwatering. Generally, on overwatered plants, the bottom portions of geraniums have yellow leaves. They may also develop pale looking water spots. If this is the case, you should immediately stop watering and allow the plants to dry out.
