Chrysanthemum Care

Temperature - Although chrysanthemums can tolerate a large range of temperature, they are happiest with a constant temperature in the range of 65-70° degrees F. Use your own sense of temperature as a guideline for your plants. If you are comfortable, your mums will be comfortable as well.

Location - Avoid placing your chrysanthemum in direct sunlight or deep shadows. A location in a nice bright room is ideal. A minimum of 12 hours of light daily will greatly increase the longevity of your potted mum.

Fertilization - Your chrysanthemum should not require any additional fertilizer while in the home. Commercial production of potted chrysanthemums is a very specialized process resulting in optimum levels of nutrition in both the leaves and the soil of your plant. There is more than enough nutrition available to your potted mum to see it through its useful life in a home environment.

Watering - Chrysanthemums require a good amount of water to maintain optimum health. Allowing the plants to dry to the point of wilting will decrease longevity considerably. There are several " rules of thumb" to use when applying water in a home environment:

    1. Gauge the weight of the plant after an irrigation. In a few days, lift the plant again. If the pot feels much lighter than previously, it is usually a good indicator that the plant needs another irrigation.

    2. Place your finger on the top layer of soil and press down slightly. If the soil feels dry to the touch, it is probably a good idea to go ahead and water again.

    3. If the leaves begin to droop slightly and they feel soft to the touch, the plant is beginning to wilt. It is very important to apply water immediately at this stage.

    4. When irrigating your potted plant, irrigate thoroughly. Wet the entire root ball and allow the excess water to leach through the holes in the bottom of your pot. This will help to maintain healthy roots, while eliminating any excess fertilizer salts that may be accumulating near the bottom of your pot.

    5. Never allow your pot to sit in a container of water. This is one of the quickest ways to destroy your roots. Once the roots are gone, the top of the plant will soon follow.

If you would like to place a saucer under your pot, try placing a half inch or so of pea gravel or large aquarium gravel in the bottom. Place your chrysanthemum on top of the stones. This will keep your pot off the bottom of the saucer and away from any harmful salts or excess water. A small amount of water in the saucer can help to increase the humidity around the plant as well.

Decorative Wraps - If your chrysanthemum was purchased with a decorative wrap, consider the following options when irrigating:

    1. Remove the pot from the wrap, irrigate until no excess water drains from the bottom of the pot and then replace the pot in its decorative wrap.

    2. Poke a few holes in the bottom of the wrap to allow excess irrigation water to escape.

    3. Remove the decorative wrap completely.
