How to Care for Geraniums in Summer?

Geraniums, also known as "Wood Begonia" or "Day Wax Red," symbolize the remembrance of beautiful past memories and gratitude for present happiness. Given the high temperatures in summer, how should we care for geraniums during this season? Let's find out.

How to Care for Geraniums in Summer?

1. Stop Fertilizing: Geraniums enter a dormant period in the summer and should not be fertilized during this time. Fertilizing during their dormancy can stress the plants and cause nutrient imbalances. When the weather becomes slightly cooler, typically in late summer or early fall, you can start applying potassium fertilizer. This is especially important because autumn is the blooming season for geraniums, and additional nutrients will help the plants bud and flower, ensuring a vibrant display of blooms.

2. Reduce Watering: Although summer temperatures are high, watering should not be frequent. Ensure the soil is not too dry but avoid overwatering, as it can lead to excessive foliage growth and hinder flowering. If there is too much water, ensure proper drainage.

3. Provide Shade: Geraniums thrive in cool, moist environments. Excessive sunlight can cause the leaves to dry out and fall off. During summer, place the plants in areas with ample indirect light, such as indoors near a south-facing window, to protect them from strong sunlight.

4. Prune Regularly: Regular pruning of geraniums is essential. After the blooming season, promptly remove the flower stalks to concentrate nutrients on new growth. Summer heat can promote bacterial growth, so it is crucial to trim the branches and leaves to maintain plant health.

5. Prevent Pests and Diseases: Ensure good ventilation for geraniums during summer. In hot and humid weather, spray Bordeaux mixture regularly to prevent pests and diseases. Remove any diseased leaves immediately upon discovery.

These are the key points for caring for geraniums in summer. Adequate sunlight aids in blooming, but avoid direct sunlight when temperatures are too high. Monitor the temperature closely and provide appropriate care to ensure the health and beauty of your geraniums.

How Do You Keep Geraniums Blooming All Summer?

Geraniums are a popular choice for gardeners due to their vibrant colors and long blooming season. With the right care, you can keep your geraniums blooming all summer. Here are some tips to help you achieve continuous blooms.

1. Choose the Right Variety: Select geranium varieties known for their long blooming periods. Zonal geraniums and ivy geraniums are excellent choices for summer-long blooms.

2. Provide Adequate Sunlight: Geraniums thrive in full sun. Ensure they receive at least 6-8 hours of direct sunlight daily. If you live in a region with intense afternoon sun, provide some afternoon shade to prevent leaf scorch.

3. Watering Properly: Geraniums prefer well-draining soil. Water them thoroughly when the top inch of soil feels dry. Avoid overwatering, as it can lead to root rot. Ensure the pots or planting beds have good drainage to prevent waterlogging.

4. Fertilize Regularly: Feed your geraniums with a balanced liquid fertilizer every 2-4 weeks during the growing season. A fertilizer high in phosphorus will promote blooming. Avoid over-fertilizing, as excessive nutrients can lead to more foliage growth at the expense of flowers.

5. Deadhead Spent Blooms: Regularly remove spent flowers to encourage the plant to produce more blooms. Pinch off the dead flowers along with a bit of the stem to stimulate new growth.

6. Prune and Pinch Back: Pinch back the stems of your geraniums to encourage bushier growth and more flowers. Regular pruning helps maintain the plant's shape and prevents it from becoming leggy. Remove any dead or yellowing leaves to keep the plant healthy.

7. Pest and Disease Control: Keep an eye out for common pests like aphids, spider mites, and whiteflies. Use insecticidal soap or neem oil to control infestations. Ensure good air circulation around the plants to prevent fungal diseases.

8. Mulch and Soil Care: Apply a layer of mulch around your geraniums to retain soil moisture and suppress weeds. Use well-draining soil with plenty of organic matter to keep the roots healthy and promote blooming.

9. Provide Support: For varieties that grow tall or have heavy flower heads, provide support with stakes or cages to keep the plants upright and prevent damage.

By following these tips, you can enjoy a vibrant display of geranium blooms all summer long. Consistent care and attention to their needs will ensure your geraniums remain healthy and continue to produce beautiful flowers.

Can Geraniums Take Full Hot Sun?

Geraniums are popular for their vibrant blooms and ease of care, making them a favorite among gardeners. However, when it comes to their light requirements, especially during the hot summer months, there are specific considerations to keep in mind. So, can geraniums take full hot sun? Let's explore this question in detail.

Light Requirements for Geraniums:

Geraniums thrive in bright light conditions and typically need at least six hours of sunlight each day to promote healthy growth and abundant flowering. However, the intensity and duration of sunlight they can tolerate depend on several factors, including the climate and time of year.

Can Geraniums Handle Full Sun?

Geraniums can indeed handle full sun, but this is more applicable in regions with moderate summer temperatures. In areas where summer temperatures soar, prolonged exposure to the full hot sun can stress the plants. Here's how to manage geraniums in hot, sunny conditions:

1. Gradual Acclimation: When transitioning geraniums to full sun, gradually acclimate them by increasing their sun exposure over a week or two. This helps prevent sunburn and shock to the plants.

2. Midday Shade: In extremely hot climates, provide some midday shade to protect geraniums from the intense afternoon sun. This can be achieved by placing them under a shade cloth or in a spot that receives filtered sunlight during the hottest part of the day.

3. Consistent Watering: Hot sun can quickly dry out the soil, so ensure geraniums receive consistent watering. Water deeply and regularly to keep the soil moist but not waterlogged. Mulching around the base of the plants can help retain soil moisture.

4. Heat-Tolerant Varieties: Some geranium varieties are more heat-tolerant than others. If you live in an area with intense summer heat, consider choosing heat-tolerant geranium varieties for better performance.

5. Container Considerations: If growing geraniums in containers, be aware that pots can heat up quickly in the sun, potentially damaging the roots. Use light-colored containers to reflect heat and consider placing them on stands to improve air circulation.

Signs of Sun Stress in Geraniums:

Even with proper care, geraniums may show signs of sun stress if the conditions are too harsh. Look out for the following symptoms:

• Wilting or drooping leaves despite adequate watering

• Leaf scorch or sunburn (brown or crispy edges)

• Stunted growth or reduced flowering

If you notice these signs, consider providing additional shade and adjusting your care routine to better suit the hot conditions.

In conclusion, while geraniums can take full sun, they require careful management in hot climates to avoid stress and damage. By providing gradual acclimation, consistent watering, and midday shade, you can help your geraniums thrive even in the hottest summer months.
