Choosing the Right Chrysanthemum Variety

Before you even think about getting your hands dirty, the first crucial step is selecting the right chrysanthemum variety for your climate and preferences. Chrysanthemums are incredibly diverse, with thousands of cultivars available, each offering unique characteristics. Consider the following factors when making your choice.

Hardiness Zones

Chrysanthemums have varying degrees of cold hardiness. Understanding your USDA hardiness zone is critical to ensuring your chosen variety will survive the winter. Some mums are hardy in colder climates, while others thrive in warmer regions. Check the plant tag or online descriptions for the hardiness zone information.

For example, if you live in Zone 5, choose varieties rated for Zones 4-6 to ensure they can withstand the winter temperatures. Planting a variety outside of its hardiness zone can lead to winter kill and the loss of your plants.

Bloom Time

Chrysanthemums are categorized by their bloom time, which typically ranges from early summer to late fall. Choose varieties with bloom times that suit your desired display. Early-blooming mums can provide color in late summer, while late-blooming varieties extend the season into the colder months.

Staggering your choices with different bloom times ensures a continuous display of color throughout the growing season. Consider the overall aesthetic you want to achieve in your garden when selecting the bloom times.

Flower Type and Color

Chrysanthemums come in a vast array of flower types, including:

  • Single: Simple, daisy-like flowers with a single row of petals.
  • Semi-Double: Flowers with multiple rows of petals.
  • Double: Flowers with many rows of petals, often fully covering the disc.
  • Pompon: Round, ball-shaped flowers.
  • Spider: Flowers with long, tubular petals that curl at the ends.

The color palette is equally diverse, spanning the spectrum from pure white and sunny yellow to vibrant reds, purples, and bronzes. Consider the color scheme of your garden and choose varieties that complement your existing plants. You can also mix and match different colors and types to create a visually interesting display.

Size and Shape

Chrysanthemums vary in size and shape, from compact, low-growing varieties to taller, bushier plants. Consider the available space in your garden and choose varieties that will fit comfortably. Dwarf varieties are ideal for containers and small spaces, while larger varieties can be used as focal points in borders.

Also, consider the shape of the plant. Some mums have a more upright growth habit, while others spread outwards. The shape of the plant will influence its overall appearance in the garden.

Common Chrysanthemum Varieties

Here are a few popular chrysanthemum varieties to get you started:

  • ‘Sheffield Pink’: A classic, early-blooming variety with soft pink, daisy-like flowers.
  • ‘Coral Charm’: A semi-double variety with vibrant coral-colored blooms.
  • ‘Grandchild’: A popular, hardy variety with double, yellow flowers.
  • ‘Minngopher’: A pompon variety with compact, red flowers.

Research different varieties online or at your local garden center to find the perfect mums for your garden. The variety you select will significantly influence your success.

Preparing the Soil for Chrysanthemums

Proper soil preparation is paramount to the health and longevity of your chrysanthemums. These plants thrive in well-draining soil that is rich in organic matter. Before planting, take the time to amend your soil to create the ideal growing conditions. The key is to provide a nutrient-rich and well-drained environment.

Soil Testing

Before planting, it’s highly recommended to test your soil. Soil tests will reveal the pH level and nutrient content of your soil. Chrysanthemums prefer a slightly acidic to neutral pH, typically between 6.0 and 7.0. A soil test will also identify any nutrient deficiencies or imbalances that need to be addressed.

You can purchase soil testing kits at most garden centers or send a sample to a local extension office for a more comprehensive analysis. This information will guide your soil amendment efforts.

Soil Amendments

Chrysanthemums benefit from soil that is rich in organic matter. Incorporate the following amendments into your soil:

  • Compost: Adds essential nutrients and improves soil structure.
  • Well-rotted manure: Provides nutrients and improves water retention.
  • Leaf mold: Improves soil structure and adds nutrients.
  • Peat moss: Improves water retention and aeration. Use sparingly, as peat moss harvesting can be environmentally damaging.

Dig the amendments into the soil to a depth of 12-18 inches (30-45 cm). This will ensure that the roots have easy access to nutrients and water. Proper soil preparation is a critical step in learning how to plant chrysanthemums. (See Also: How to Plant Weed Seeds Outside: A Complete Guide)

Drainage

Chrysanthemums are susceptible to root rot, so good drainage is essential. If your soil is heavy clay, it’s crucial to improve drainage. You can do this by adding organic matter, such as compost and well-rotted manure, or by incorporating sand or perlite.

You can also consider planting your mums in raised beds or containers to ensure good drainage. Poor drainage can quickly lead to root rot and the demise of your plants.

Sunlight Requirements

Chrysanthemums thrive in full sun, which means they need at least six hours of direct sunlight per day. Choose a planting location that receives ample sunlight. Insufficient sunlight will result in fewer blooms and leggy growth.

If you live in a very hot climate, some afternoon shade may be beneficial to prevent the plants from overheating. However, ensure that the plants still receive at least six hours of sunlight.

Planting Chrysanthemums: Step-by-Step Guide

Now that you’ve chosen your varieties and prepared your soil, it’s time to learn how to plant chrysanthemums. Follow these steps for the best results.

Timing

The ideal time to plant chrysanthemums depends on your climate and the type of plant you’re growing. In general, there are two common planting windows:

  • Spring Planting: In cooler climates, plant chrysanthemums in the spring, after the last frost. This allows the plants to establish a strong root system before the heat of summer.
  • Summer/Early Fall Planting: In warmer climates or with established plants, you can plant in late summer or early fall, about 6-8 weeks before the first expected frost. This gives the plants time to bloom before the cold weather sets in.

Avoid planting chrysanthemums during the hottest part of summer, as this can stress the plants. The right planting time will dramatically improve your success.

Spacing

Proper spacing is essential to allow for adequate air circulation and prevent overcrowding. Space your chrysanthemums according to the plant tag instructions, typically 18-24 inches (45-60 cm) apart, depending on the variety.

Allowing enough space between plants will also help to prevent the spread of diseases. Adequate spacing is a key factor in how to plant chrysanthemums successfully.

Planting Procedure

Follow these steps to plant your chrysanthemums:

  1. Dig the Hole: Dig a hole that is twice as wide as the root ball and just as deep.
  2. Remove the Plant: Gently remove the chrysanthemum from its container, being careful not to damage the roots.
  3. Loosen the Roots: If the roots are tightly packed, gently loosen them with your fingers.
  4. Position the Plant: Place the plant in the hole, ensuring that the top of the root ball is level with the soil surface.
  5. Backfill the Hole: Fill the hole with the amended soil, gently patting it around the roots.
  6. Water Thoroughly: Water the plant deeply after planting to settle the soil and encourage root growth.
  7. Mulch: Apply a layer of mulch, such as shredded bark or straw, around the base of the plant to retain moisture, suppress weeds, and regulate soil temperature.

Following these steps will ensure your plants get off to a strong start.
