Calendula Flowers

Today is officially the first of December which means that the cooler months are finally here but as the weather cools down we can continue to have a beautiful colorful garden that can continue to flourish during this time of the year. A plant that can keep your South Florida garden colorful is calendula, this garden beauty is native to Southwestern Asia, Macaronesia, Europe, and the Mediterranean. Calendula is a short-lived herbaceous flowering plant that’s in the daisy family Asteraceae and is in a genus of about 12-15  annuals and perennials.

What I love about calendula is these flowering beauties will attract pollinators (butterflies and bees) as a bonus to your South Florid garden, which can get things going. Below we will show you how to grow calendula successfully.

Planting Location

Calendula thrives best in cool conditions during early spring and fall but will not withstand the summer’s heat, water calendula regularly until the flowers are established. If the soil dries out then water thoroughly. Make sure that calendula gets sufficient water. The soil should be somewhat moist at all times and not waterlogged.

The Soil Type

Calendula will thrive in soils that are ordinary but will perform their best in organic nutrient-rich soil.

Proper Spacing

When sowing calendula in your garden plant seeds in rows and give a spacing of 5 inches between seeds. At maturity, calendula can reach heights of 1-2 ft tall and 1-2 ft. wide

Watering Methods

Make sure that your calendulas are watered regularly because prolonged periods of drought will cause flowers to wilt followed by flower drop.

Fertilizing Methods

Fertilizer applications will provide nutrients for your calendula however too much nitrogen will encourage more leaf growth and less flower production, for the best results read and follow the manufacturers.

Mulching Methods

Once you have planted your calendula it’s time to mulch, the addition of mulch will help to keep weeds down, conserve soil moisture, and beautify, and as mulch breaks down will add nutrients to the soil. A layer of hay or natural black mulch will work wonders.

Garden Insect Pest Issues

Calendula has its share of garden insect pests, as soon as insects are spotted control measures should be put in place, here is what to watch for when doing your inspection.

A pesticide that will bring control is insecticidal soap, before using this soap spray read and follow the manufacturer’s directions for the best results. Be warned however that insecticidal soap can also negatively impact beneficial insects if they come in contact at the time of application. If beneficial insects are present don’t apply, wait for them first to move away from ( garden pests)  infested plants.

The beneficial insects that calendula attracts are hoverflies, ladybugs, and lacewings, these beneficials will control garden pests. Slugs also find calendula a delicacy, if slugs are spotted, hand-picking and throwing them in a container of soapy water will bring elimination. To limit or keep snails free from eating your calendula don’t overuse mulch and keep your garden free of debris which will encourage their presence. If slug infestation is high then consider using snail bait.

Cabbage loppers are another pest, these garden pests are small caterpillars but can do huge damage. Control measures include the use of Bt thuringienis or encouraging songbirds into your garden. If using Bt thuringienis read and follow the directions for the best results or if songbirds are desired here is what you can do.

Grasshoppers may be seen at times as well, if grasshoppers are spotted the presence of birds will bring control also consider using nosema Locustae bait. To apply simply broadcast this bait over your garden and the surrounding areas. The bait can be applied in early spring before the baby grasshoppers hatch and emerge.

Disease Issues

A crowed plant bed and wet conditions will encourage powdery mildew, to discourage powdery mildew clear crowed beds to encourage proper circulation. Treat powdery mildew with fungicides including sulfur, neem oil, copper, and potassium.

The Benefits of Pinching Calendula

Pinching will encourage flower plants to produce more flower blooms when removing faded or spent flowers pinch the spent blossoms at the base of the stem or behind the bud. This will encourage new growth.

Pruning Methods

If calendula is growing too vigorously then you may have to prune or trim them back a bit.

Growing Calendula as a Potted Plant

Container-grown calendula is another great way to grow these garden beauties,  containers that are used should have drain holes for water to drain once plants receive sufficient water. And organic potting soil is ideal for growing calendula from containers. Give calendula a regular feeding with a balanced fertilizer for example 20-20-20. The removal of spent or faded flowers by pinching will encourage a fuller plant with an abundance of flowers.

Bonus Just for You

  • Mature seedlings can be planted in a deck planter or transplanted and grown in window boxes.
  • Before sowing seeds spreading a layer of compost in your garden will encourage healthy growth.
  • The flower colors calendula are red, yellow, pink, orange, and white.
  • A hard frost will kill calendula.

  1. Hey Oscar, good take on how to keep things colorful during the colder months. I’ve seen calendulas, but never knew them by name – nice option to have for tropical areas like South FL. Those of us in the higher latitudes have to get super creative in the winter. Thanks for sharing – I’m actually researching now what plants I could use for winter color in my area.
