Chrysanthemums, also known as mums, are vibrant and stunning flowers that require specific light conditions to thrive. Understanding the light requirements of chrysanthemums is crucial for ensuring their healthy growth and abundant blooms.


Chrysanthemums thrive in full sun conditions, making it essential to provide them with at least six hours of direct sunlight each day. This exposure to sunlight is vital for their photosynthesis process and overall development. When exposed to adequate sunlight, chrysanthemums produce the fullest plants and most beautiful blooms.

While chrysanthemums can tolerate some partial shade, they truly flourish in full sun. By placing them in an area that receives ample sunlight, you can promote their healthy growth and encourage more abundant flower production.

To provide sufficient sunlight for your chrysanthemums, choose a location in your garden that offers unobstructed access to the sun for most of the day. Avoid areas that are heavily shaded or receive only dappled sunlight, as this may hinder their growth and affect their ability to produce vibrant blooms.

Chrysanthemum Watering

Proper watering is essential for the health and vitality of your chrysanthemums. These lovely flowers prefer evenly moist soil, so it’s important to pay attention to their water requirements.

Chrysanthemums should be watered when the top 1 inch of soil feels dry to the touch. This ensures that the plants have enough moisture for optimal growth without becoming waterlogged.

When watering your chrysanthemums, it’s important to focus on the soil level and avoid watering the blooms directly. Watering the blooms can lead to diseases, so it’s best to direct the water towards the soil instead.

Remember to water the chrysanthemum plants until the soil is moist, but be careful not to overwater and make the soil soggy. Overwatering can lead to root rot and damage the plant’s overall health.

If you are growing chrysanthemums in pots, it’s important to water the surface of the soil until moisture begins to drain from the bottom of the pot. This ensures that the roots receive enough water and excess moisture can escape.

  • Water chrysanthemums when the top 1 inch of soil feels dry.
  • Avoid watering the blooms directly to prevent diseases.
  • Maintain moist but not soggy soil to prevent root rot.
  • For potted chrysanthemums, water until moisture drains from the bottom of the pot.

Chrysanthemum Fertilizing

Proper fertilizing is crucial for the healthy growth and abundant blooms of chrysanthemums. These vibrant flowers benefit from regular fertilization, especially during their vegetative phase.

When planting and during the vegetative growth period, it is recommended to use a 20-10-20 fertilizer, which contains essential nutrients to support their development. This balanced formulation ensures that chrysanthemums receive the right blend of nutrients for optimal growth.

Once the chrysanthemums are established, you can switch to a 5-10-5 liquid fertilizer. This type of fertilizer provides the necessary nutrients in a readily available form.

Start fertilizing your chrysanthemums after the danger of frost has passed, typically in early spring or late winter. Always refer to the product label instructions to determine the correct amount of fertilizer to use for your specific garden. Over-fertilizing can be detrimental to the plants, so it’s important to follow the recommended dosage.

However, it’s crucial to stop fertilizing established chrysanthemums after July. This helps prevent damage from potential frost and allows the plants to transition into their natural dormancy period.

Incorporating these fertilizing practices into your chrysanthemum care routine will provide the essential nutrients necessary for healthy growth and the beautiful blooms that these flowers are known for.

Chrysanthemum Potting

Repotting chrysanthemums is essential for their healthy growth and development. When it comes to chrysanthemum potting, here are a few steps to follow:

  1. Choose a pot that is slightly larger than the original container. This will provide enough space for the roots to spread and grow.
  2. Fill the bottom of the new pot with potting soil. This will ensure proper drainage and aeration for the chrysanthemum plant.
  3. Gently break up any tangled roots before placing the chrysanthemum plant in the new pot. Be careful not to damage the roots during this process.
  4. Position the chrysanthemum plant in the new pot, making sure that the soil surrounds the roots completely. Avoid burying the stem too deep.
  5. Water the chrysanthemum thoroughly until water drains from the bottom of the pot. This will help the plant settle into its new environment.

Chrysanthemum Propagation

Chrysanthemums can be propagated through division and cuttings, making it easy to expand your chrysanthemum collection and share them with others.


Division is the simplest and quickest method of chrysanthemum propagation. If you already have established chrysanthemum plants in your garden that are at least two years old, you can divide them to create new plants.

To divide chrysanthemums, carefully untangle the roots of an existing plant and gently separate them into multiple clumps. Replant each clump at the same depth as the original plant. Ensure that each new division has its own set of roots.

This method allows you to create multiple plants from a single mature chrysanthemum, guaranteeing healthier root systems and increasing the chances of successful growth.


Another method of propagating chrysanthemums is through cuttings. This method involves taking a stem from a healthy chrysanthemum plant and encouraging it to grow roots.

Start by selecting a healthy stem with at least two sets of leaves. Make a clean cut just below a node (where the leaves attach to the stem) using a sterilized knife or shears.

Dip the cut end into a rooting hormone to encourage root growth, then plant it in a container filled with moist potting mix. Make sure the cutting is inserted at least an inch into the soil to provide stability.

Place the container in a warm location with bright, indirect light. Mist the cutting regularly to maintain humidity and prevent the soil from drying out. After a few weeks, the cutting should develop roots.

Once the roots have grown a few inches in length, transplant the young chrysanthemum outside into a prepared flower bed or container.

Chrysanthemum Growth and Development

Chrysanthemums, like any other plant, require proper care and maintenance for optimal growth and development. Here are some essential tips to ensure your chrysanthemums flourish:

1. Pruning and Pinching

Pruning and pinching are crucial for promoting compact growth and encouraging more abundant blooms in chrysanthemums. Pinch the plants back periodically throughout the summer until July 4th to stimulate branching and stockier growth. This practice helps create a fuller and more robust plant, resulting in a profusion of beautiful flowers.

2. Spring Pruning

Pruning in the spring is essential for chrysanthemums as it removes old stems and promotes new growth. It is best to prune around early to mid-spring, before new growth begins. By removing any dead or damaged stems, you encourage the plant to focus its energy on healthy new growth, resulting in stronger and more vibrant blooms.

3. Chrysanthemum Propagation

Chrysanthemums can be grown from seeds, but to ensure the desired characteristics of the parent plant, it is recommended to use purchased seeds or propagated plants. Division and cuttings are common methods for chrysanthemum propagation. Division involves untangling the roots of an established plant and replanting them at the same depth as the original plant. Cuttings can be taken from stems, dipped in rooting hormone, and planted until roots develop.

4. Healthy Soil and Fertilization

Chrysanthemums thrive in well-draining soil enriched with organic matter. Regularly fertilize the plants during their vegetative growth phase to provide the necessary nutrients for healthy development. Use a balanced fertilizer according to the instructions provided, and avoid over-fertilization, as it can lead to excessive foliage growth with fewer blooms.

5. Adequate Watering

Proper watering is essential for chrysanthemum growth and development. Keep the soil evenly moist, but not waterlogged, as excessive moisture can lead to root rot. Water at the soil level rather than directly on the blooms to prevent diseases. Aim to water when the top inch of soil feels dry to the touch.
