Planting Chrysanthemums

Growing chrysanthemums is easy and rewarding, especially with the right planting techniques. Below are the essential steps for planting chrysanthemum flowers.

Selecting the Proper Location

Chrysanthemums grow best in a location that receives at least six hours of direct sunlight a day. Choose a spot in your garden that offers full sun, and make sure it has well-draining soil. Avoid planting chrysanthemums in areas that are prone to standing water or where the soil is heavy.

Preparing the Soil

Before planting, prepare the soil by digging down at least six inches and removing any rocks, roots, or other debris. Mix in organic matter or compost to improve soil quality and drainage. If the soil is heavy and dense, consider adding sand or perlite to improve aeration.

Planting the Chrysanthemums

Once the soil has been prepared, it’s time to plant your chrysanthemums. Dig a hole that is slightly wider and deeper than the root ball of the plant. Place the plant in the hole, backfill with soil, and gently pat the soil down around the base of the plant. Water thoroughly.

When planting multiple chrysanthemums, space them at least 18 to 24 inches apart to allow for proper air circulation and prevent overcrowding.

Caring for Newly Planted Chrysanthemums

After planting, water your chrysanthemums regularly to help them establish their roots. Keep the soil moist but not waterlogged, and avoid overhead watering, which can damage the plants and promote the growth of fungal diseases.

Fertilize your chrysanthemums once a month with a balanced fertilizer to promote healthy growth and abundant blooms. Follow the instructions on the package for the correct amount of fertilizer to use.

By following these planting tips, your chrysanthemums will be well on their way to growing strong and beautiful throughout the season.

Watering and Fertilizing Chrysanthemums

Proper watering and fertilizing are essential for the healthy growth and abundant blooms of chrysanthemums. Follow these tips to ensure your plants receive the right care:

Watering Schedule

Chrysanthemums require regular watering, especially during hot and dry weather. Water them deeply once a week, providing enough water to saturate the soil to a depth of 6-8 inches. Avoid overwatering, as it can cause root rot and other health issues.

It’s important to water your plants early in the day to allow the leaves to dry before nighttime. Wet foliage at night can promote fungal growth and diseases.

Fertilizing Chrysanthemums

Chrysanthemums require regular fertilization to provide them with the nutrients they need to thrive. Use a balanced 10-10-10 fertilizer every two to three weeks during the growing season, starting in early spring and ending in early autumn.

Alternatively, you can use a slow-release fertilizer at the beginning of the growing season, which will provide nutrients gradually over several months. Follow the instructions on the fertilizer package for the appropriate application rates.

Avoid overfertilizing, as it can lead to unhealthy growth and reduced bloom production. Always water your plants well after fertilizing to ensure the nutrients reach the roots.

Providing Adequate Sunlight and Temperature

Chrysanthemums require ample sunlight and the right temperature to thrive. These plants prefer full sun exposure for at least six hours daily and grow well in temperatures between 55 and 70 degrees Fahrenheit.

Make sure your chrysanthemum plants are not exposed to extreme temperatures, as this can cause leaf scorch and damage to the plant. If the temperatures are too high, move the plants to a shaded area to prevent sunlight from burning the leaves.

Conversely, if the temperature drops too much, your chrysanthemums may not bloom properly. To protect your plants from frost, cover them with blankets or garden fabric, or move them indoors to a warmer place.

Providing Shade

If your chrysanthemums are in areas that receive full sunlight throughout the day, they may require a little shade to prevent sunburn. Consider using a shade cloth or planting taller plants nearby that can provide shade for the chrysanthemum plants.

Optimizing Soil Temperature

The temperature of the soil also plays a vital role in the growth and development of chrysanthemum plants. To maintain optimal soil temperature, you can cover the ground with mulch or black plastic to keep the soil warm during colder months. You can also use a shade cloth or add a layer of organic mulch to keep the soil cool during hot summer months.

By optimizing sunlight and temperature, you can ensure that your chrysanthemum plants grow vibrant and healthy, with plenty of colorful blooms to brighten up your garden.

How to Grow and Care for Chrysanthemum Flowers: Pruning and Pinching Chrysanthemums

Pruning and pinching are crucial techniques for maintaining the shape and encouraging bushier growth in chrysanthemum plants. These techniques involve removing unwanted growth and maintaining the desired shape of the plant.

Pinching is the process of removing the tip of each stem, which stimulates branching and leads to a fuller, bushier plant. This should be done when the plant is about 6 inches tall and repeated two or three more times throughout the growing season.

Pruning involves removing old, weak, or dead growth to promote new growth and improve the overall health of the plant. Prune your chrysanthemums in the spring when new growth appears and throughout the growing season as needed.

Always use sharp, clean pruning shears or scissors to prevent damaging the plant. When cutting, make clean, angled cuts just above a leaf node or bud.

Chrysanthemum Gardening Tips

  • Pinch and prune regularly to encourage bushier growth and maintain the desired shape of the plant.
  • Remove spent blooms to promote continuous flowering.
  • Fertilize your chrysanthemums regularly, but avoid over-fertilizing, which can lead to leggy growth.
  • Water your plants deeply and regularly to keep the soil evenly moist, but avoid overwatering, which can lead to root rot.
  • Avoid crowded plantings, which can lead to poor air circulation and increased risk of disease.

Tips: If your chrysanthemums have become too leggy, you can cut them back to about 6 inches in height in the spring to encourage bushier growth. Also, be sure to remove any diseased or damaged growth promptly to prevent the spread of disease.

Propagating Chrysanthemums

If you want to expand your collection of chrysanthemums, propagating your plants is the way to go. There are three main methods for propagating chrysanthemums: division, cuttings, and seed propagation.


Dividing chrysanthemums is best done in the early spring or late autumn. Start by digging up the entire plant and gently separating the root ball into smaller clumps. Ensure each clump has its own set of leaves and roots. Replant the divided clumps in well-draining soil and water generously.


The best time to take cuttings from chrysanthemums is in the late spring or early summer. Select a healthy stem and cut it at a 45-degree angle just below a leaf node. Strip off any leaves from the bottom half of the stem and dip it in rooting hormone powder. Plant the stem in well-draining soil and water generously.

Seed Propagation

If you’d like to grow chrysanthemums from seed, start by sowing the seeds indoors about 8 to 10 weeks before the last frost date. Sow the seeds thinly on top of a good-quality seed compost and cover them with a thin layer of vermiculite. Keep the soil moist and place the tray in a warm, well-lit area. Once the seedlings have grown to about 2 inches tall, transplant them in individual pots and gradually acclimate them to outdoor conditions before planting them in the garden.

Dealing with Common Chrysanthemum Pests and Diseases

Proper chrysanthemum plant care involves preventing and controlling pests and diseases that can harm your plants. Here are some common chrysanthemum pests and diseases and how to deal with them:


AphidsSmall, soft-bodied insects that suck sap from leaves and stems, causing them to curl and distort.Spray plants with a strong jet of water to knock aphids off. Apply insecticidal soap or neem oil to kill remaining aphids.
Spider mitesSmall, reddish-brown pests that suck sap from leaves, leaving them speckled with yellow or white spots.Apply insecticidal soap or neem oil to kill spider mites. Keep plants well-watered to prevent infestations.
WhitefliesSmall, white insects that feed on plant sap, causing leaves to turn yellow and die.Hang yellow sticky traps around plants to catch adult whiteflies. Apply insecticidal soap or neem oil to kill immature whiteflies.


Leaf spotBlack or brown spots on leaves that can cause them to drop prematurely.Remove affected leaves and destroy them. Apply a fungicide to prevent further spread.
Powdery mildewA white, powdery coating on leaves and stems that can stunt growth and cause leaves to curl.Remove affected leaves and destroy them. Apply a fungicide to prevent further spread.
RustOrange or brown spots on leaves that can cause them to yellow and drop off.Remove affected leaves and destroy them. Apply a fungicide to prevent further spread.

Preventing pest and disease problems in the first place is the best strategy. Keep your chrysanthemum plants healthy and vigorous by providing adequate sunlight, water, and nutrients, and maintaining good hygiene practices, such as removing dead plant material and avoiding overcrowding. Early detection and prompt treatment are also key to preventing pest and disease infestations from getting out of control.

Overwintering Chrysanthemums

Chrysanthemums are hardy perennials that can survive through the winter months, but they need some extra care to ensure their survival. Follow these tips to help your chrysanthemums make it through the cold months.

Preparing for Winter

Before the first frost, it’s important to prepare your chrysanthemum plants for winter. Cut back the stems to about 6 inches above the ground. This will help prevent snow and ice from breaking the stems. Remove any dead or diseased leaves and mulch around the base of the plant to protect the roots.

Providing Adequate Protection

Chrysanthemums need protection from the cold temperatures and harsh weather conditions of winter. Cover the plants with a thick layer of straw or evergreen boughs to insulate them. This will help keep the plants warm and prevent the soil from freezing.

Watering and Fertilizing

While chrysanthemums don’t need much water during the winter months, they do need to be watered occasionally if the weather is dry. Check the soil regularly and water if it feels dry to the touch. Avoid fertilizing your chrysanthemums during the winter as this can stimulate new growth, which is vulnerable to frost damage.

Spring Care

In the spring, remove the protective covering from your chrysanthemum plants. As the weather warms up, you can gradually increase the amount of water they receive. Fertilize your plants with a balanced fertilizer to promote new growth and healthy blooms.

By following these simple steps, you can help your chrysanthemums survive the winter and thrive in the spring. Remember to always provide proper chrysanthemum plant care throughout the year for the best results.
