How To Plant Chrysanthemums Outside: A Guide For Beginners To Create A Vibrant Garden

Chrysanthemums, often referred to as “mums,” are beloved for their vibrant hues and prolonged blooming period, extending from late summer to early winter. Whether you’re an experienced gardener or a novice looking to add color and life to your outdoor space, learning how to plant chrysanthemums outside is a rewarding endeavor. This comprehensive guide will provide you with step-by-step instructions, essential tips, and troubleshooting advice to ensure your chrysanthemums thrive and flourish.

Choosing the Right Chrysanthemum Varieties

With numerous chrysanthemum varieties available, selecting the ones that suit your climate, soil conditions, and personal preferences is crucial. Consider these factors when making your choice:

• Climate: Chrysanthemums generally thrive in USDA hardiness zones 4 through 9. Choose varieties that are suitable for your specific zone to ensure optimal growth and performance.
• Soil Conditions: Chrysanthemums prefer well-draining, fertile soil with a slightly acidic pH level. If your soil is not ideal, consider amending it with organic matter or using raised beds to improve drainage and fertility.
• Personal Preferences: Chrysanthemums come in a wide range of colors, shapes, and sizes. Select varieties that align with your aesthetic preferences and desired garden aesthetic.

Preparing the Planting Site

Before planting your chrysanthemums, it’s essential to prepare the planting site adequately to ensure they have the best chance of thriving. Here’s how to do it:

1. Choose a Suitable Location: Select a spot that receives full sun for at least 6 hours daily. Chrysanthemums need ample sunlight to produce abundant blooms and maintain their vibrant colors.
2. Prepare the Soil: Test your soil’s pH level using a soil test kit. If the pH is not slightly acidic (between 6.0 and 6.5), amend it with sulfur or lime to achieve the desired pH range. Till the soil to a depth of 12 inches to loosen it and incorporate organic matter, such as compost or well-rotted manure, to improve soil structure and fertility.
3. Improve Drainage: Ensure the planting site has good drainage to prevent waterlogging, which can lead to root rot and other issues. If necessary, install raised beds or create mounds to elevate the planting area and improve drainage.

Planting Chrysanthemums Outdoors

Once you’ve chosen the right varieties and prepared the planting site, it’s time to plant your chrysanthemums outdoors. Follow these steps for successful planting:

1. Spacing: Space your chrysanthemums according to their mature size. For standard-sized varieties, leave 18 to 24 inches between plants. For compact or dwarf varieties, space them 12 to 18 inches apart.
2. Digging Holes: Dig holes that are slightly larger than the root balls of your chrysanthemum plants. The holes should be about 6 to 8 inches deep.
3. Planting: Gently remove the chrysanthemum plants from their containers, taking care not to damage the roots. Place each plant in a prepared hole and backfill with soil, ensuring the root ball is covered and the soil is firm around the base of the plant.
4. Watering: Water the newly planted chrysanthemums thoroughly to settle the soil and help them establish roots.

Caring for Chrysanthemums

Proper care is essential to keep your chrysanthemums healthy and blooming beautifully throughout the season. Here are some essential care tips:

• Watering: Chrysanthemums need regular watering, especially during hot and dry weather. Water deeply and infrequently, allowing the soil to dry out slightly between waterings. Avoid overwatering, as it can lead to root rot.
• Fertilizing: Feed your chrysanthemums with a balanced fertilizer, such as a 10-10-10 NPK fertilizer, every 4 to 6 weeks during the growing season. Avoid fertilizing in late summer or fall, as it can stimulate new growth that may not have time to mature before frost.
• Deadheading: Regularly deadhead spent blooms to encourage new growth and flowering. Simply remove the faded flowers from the plant, cutting back to the nearest set of leaves.
• Pinching: Pinching back the tips of young chrysanthemum plants can help promote bushier growth and more blooms. Pinch back the growing tips when the plants are about 6 to 8 inches tall.

Troubleshooting Common Chrysanthemum Problems

Despite your best efforts, you may encounter some common issues with your chrysanthemums. Here are some common problems and their solutions:

• Pests: Aphids, spider mites, and thrips are common pests that can infest chrysanthemums. Use insecticidal soap or neem oil to control these pests.
• Diseases: Powdery mildew and botrytis blight are common diseases that can affect chrysanthemums. To prevent these diseases, ensure good air circulation and avoid overhead watering. If diseases occur, apply appropriate fungicides.
• Wilting: Wilting can be caused by various factors, including drought, root rot, or disease. Check the soil moisture, inspect the roots for signs of rot, and treat any underlying issues.

Overwintering Chrysanthemums

In colder climates, it’s essential to protect your chrysanthemums from frost and freezing temperatures. Here’s how to overwinter chrysanthemums successfully:

• Mulching: Apply a layer of mulch, such as straw or compost, around the base of your chrysanthemum plants to insulate the roots and protect them from the cold.
• Covering: In areas with severe winters, you may need to cover your chrysanthemums with a frost blanket or burlap to provide additional protection from the cold.
• Bringing Indoors: If you live in a very cold climate, you can dig up your chrysanthemum plants and bring them indoors for the winter. Keep them in a cool, bright location and water them sparingly.

The Chrysanthemum Companion: Enhancing Your Garden with Complementary Plants

Chrysanthemums can be beautifully paired with other plants to create a stunning and cohesive garden display. Here are some companion plants that complement chrysanthemums well:

• Asters: Asters are another fall-blooming flower that pairs well with chrysanthemums. They come in a variety of colors, including purple, blue, and white, and can add height and texture to your garden.
• Ornamental Grasses: Ornamental grasses, such as maiden grass and feather reed grass, can provide a backdrop for your chrysanthemums and add movement and interest to your garden.
• Sedum: Sedum is a low-growing succulent that can add color and texture to the foreground of your chrysanthemum display. It also attracts pollinators, such as bees and butterflies.
