Mums, also known as chrysanthemums, are beloved for their vibrant blooms and ability to brighten any garden. However, summer presents unique challenges for these hardy plants. Knowing how to care for mums in summer ensures they thrive and continue to produce beautiful flowers throughout the season. This guide will help you keep your mums happy and healthy all summer long.

Watering Your Mums

How Often Should You Water Mums? Consistent watering is key, especially during hot summer months. Aim for deep watering, ensuring the water reaches the roots, about once a week, or more frequently during extended heatwaves. Check the soil moisture before watering; if the top inch feels dry, it's time to water.

Watering Techniques: Avoid overhead watering, which can lead to fungal diseases. Instead, water at the base of the plant, using a soaker hose or watering can. This delivers water directly to the roots and minimizes leaf wetness.

Signs of Underwatering: Wilting leaves, dry soil, and stunted growth are all signs your mums need more water. Address these issues promptly to prevent irreversible damage.

Fertilizing Your Mums for Summer Blooms

Choosing the Right Fertilizer: Use a balanced liquid fertilizer, such as a 10-10-10 formula, diluted to half strength. Over-fertilizing can harm your mums, so follow the package instructions carefully.

Fertilizing Schedule: Apply fertilizer every 2-3 weeks during the summer growing season. Avoid fertilizing during periods of drought or extreme heat.

Protecting Mums from Summer Pests and Diseases

Common Pests: Mums can be susceptible to various pests, including aphids, spider mites, and slugs. Regularly inspect your plants for signs of infestation.

Pest Control: Use insecticidal soap or neem oil to control pests organically. For severe infestations, consider using a targeted insecticide according to the label's instructions.

Disease Prevention: Good air circulation is crucial in preventing fungal diseases like powdery mildew. Space your mums appropriately and avoid overhead watering.

Pruning and Deadheading Mums in Summer

Deadheading: Regularly remove spent blooms to encourage more flowering. This prevents the plant from putting energy into seed production and promotes continuous blooming.

Pruning: Summer pruning is generally not recommended for mums as it can disrupt blooming. However, removing any dead or damaged stems is beneficial.

Providing Summer Shade for Mums

Protecting from Intense Sun: While mums generally tolerate full sun, intense summer heat can stress them. Consider providing afternoon shade, especially during the hottest part of the day. This can be done by using shade cloth or strategically planting taller plants nearby.

Monitoring for Stress: Watch for signs of heat stress, such as wilting, leaf scorch, and reduced flowering. Adjust watering and shading as needed to alleviate stress.

Preparing Your Mums for Fall

As summer transitions to autumn, the care for your mums changes slightly. This is the time to start preparing them for the cooler months ahead.

Reducing Watering: Gradually reduce watering frequency as temperatures cool. Overwatering in autumn can make plants more susceptible to winter damage.

Cutting Back: In late autumn, after the first frost, cut back your mums to about 6 inches from the ground. This promotes healthy growth the following spring.

Frequently Asked Questions (FAQ)

Q: My mums are wilting, what should I do?

A: Check the soil moisture. If it's dry, water deeply. If the soil is moist, the wilting might be due to heat stress. Provide some shade and ensure adequate airflow.

Q: How do I prevent powdery mildew on my mums?

A: Ensure good air circulation by spacing plants properly. Avoid overhead watering, which can create a humid environment conducive to mildew.

Q: When should I fertilize my mums?

A: Fertilize every 2-3 weeks during the summer growing season using a balanced liquid fertilizer, diluted to half strength.

By following these simple yet effective tips, you can ensure your mums thrive throughout the summer and continue to provide a stunning display of color in your garden. Remember that consistent attention to watering, fertilizing, and pest control will result in healthy, vibrant plants that will reward you with abundant blooms all season long.
