What To Know
- The best time to plant chrysanthemums outdoors is in the spring after the last frost.
- Plant the chrysanthemums at the same depth they were growing in their containers, ensuring the crown (where the stem meets the roots) is slightly above the soil line.
- Apply a layer of mulch around the base of the plants to protect their roots from frost and cold temperatures.
Chrysanthemums, with their vibrant blooms and diverse colors, are a beloved addition to any garden. But can these cheerful flowers truly thrive outside? The answer is a resounding yes! While chrysanthemums are often associated with indoor displays, they are perfectly capable of flourishing in outdoor environments. This comprehensive guide will delve into the specifics of growing chrysanthemums outdoors, covering everything from choosing the right varieties to ensuring their optimal growth and care.
Understanding Chrysanthemum Varieties
The first step to successful outdoor chrysanthemum cultivation is selecting the appropriate varieties. Not all chrysanthemums are created equal when it comes to their tolerance for outdoor conditions.
- Hardy Chrysanthemums: These varieties are known for their resilience and ability to withstand colder temperatures. They are ideal for planting in gardens where they can endure frost and winter conditions. Popular hardy chrysanthemum varieties include ‘Clara Curtis’ and ‘Pink Floyd’.
- Non-Hardy Chrysanthemums: These varieties, often labeled as “annuals,” are typically treated as seasonal plants. They thrive in warm weather but may not survive harsh winters. Examples of non-hardy chrysanthemums include ‘Apricot Apricot’ and ‘Red Velvet’.
Choosing the Perfect Location
Once you’ve chosen your chrysanthemum variety, selecting the right location is crucial. Chrysanthemums thrive in sunny spots with well-drained soil.
- Sunlight: Aim for a location that receives at least six hours of direct sunlight daily. This will encourage robust growth and abundant blooms.
- Soil: Well-drained soil is essential for chrysanthemums. Avoid areas with poor drainage, as this can lead to root rot. If your soil is prone to compaction, consider amending it with compost or other organic matter to improve drainage.
Planting Your Chrysanthemums
The best time to plant chrysanthemums outdoors is in the spring after the last frost.
- Spacing: Allow adequate space between plants, typically 12-18 inches, to prevent overcrowding and ensure good air circulation.
- Planting Depth: Plant the chrysanthemums at the same depth they were growing in their containers, ensuring the crown (where the stem meets the roots) is slightly above the soil line.
- Watering: Water your newly planted chrysanthemums thoroughly after planting to help them establish themselves.
Providing Optimal Care
Once your chrysanthemums are in the ground, consistent care will help them flourish.
- Watering: Water regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged.
- Fertilizing: Feed your chrysanthemums with a balanced fertilizer every few weeks during the growing season. This will provide them with the nutrients they need to produce abundant blooms.
- Deadheading: Deadheading, or removing spent blooms, encourages the plant to produce more flowers. Regularly remove faded blossoms to prolong the blooming period.
- Pinching: Pinching, or removing the growing tips of the stems, promotes bushier growth and more flowers. This technique is especially helpful for varieties that tend to grow tall and leggy.
Protecting Your Chrysanthemums
While chrysanthemums are relatively hardy, they can be susceptible to certain pests and diseases.
- Pests: Common pests include aphids, spider mites, and whiteflies. Regularly inspect your plants for signs of infestation and treat promptly with insecticidal soap or neem oil.
- Diseases: Common diseases include powdery mildew and rust. These diseases can be prevented by ensuring good air circulation and avoiding overhead watering.
Enjoying Your Outdoor Chrysanthemums
With proper care, your chrysanthemums will reward you with a dazzling display of vibrant blooms. Enjoy their beauty throughout the fall season, and consider bringing some indoors to brighten up your home during the colder months.
Beyond the Blooms: Chrysanthemums in Your Garden
Chrysanthemums are not only beautiful but also beneficial to your garden ecosystem. They attract beneficial insects, such as ladybugs and lacewings, which help control garden pests. Their dense foliage also provides shelter for small animals, creating a welcoming habitat for wildlife.
The End of the Blooming Season: Winter Care
For hardy chrysanthemum varieties, winter care is essential for their survival.
- Mulching: Apply a layer of mulch around the base of the plants to protect their roots from frost and cold temperatures.
- Pruning: In late fall, cut back the stems to about 6 inches above the ground. This will help prevent damage from winter winds and snow.
A Lasting Legacy: Propagating Chrysanthemums
Chrysanthemums can be easily propagated through cuttings. This allows you to create new plants from your existing ones, ensuring a continued supply of these beautiful flowers.
