Although it will grow in poorer soils, calendula prefers loose, fertile soil for maximum bloom and growth. When planting in flowerbeds, mix in generous amounts of compost to the planting hole to provide plenty of nutrients as it grows.

In Season Care & Maintenance – How To Grow Calendula

Water seedlings and transplants frequently until plants have established roots into the soil. As a drought-resistant herbaceous plant, calendula actually suffers more as a mature plant from over watering than under watering.

Once plants have established in beds, they will rarely if ever need watering except in extremely dry or drought-like conditions. Container plants will require more frequent watering, but be sure soil has dried out completely between watering.

Pinching back calendula when it first begins to grow will create bushier, more full plants. Once plants begin to bloom, deadhead the spent flowers to keep new blooms coming on strong.

When plants are young, pinching back the top growth a few inches will help to create thick, sturdy foliage. It will also help the plant to fill it’s entire canopy with blooms as it keeps it more compact.

Mulching plants will help to keep competing weeds at bay, but keep mulch a few inches away form the main stem to prevent rot.

Fertilizing – How To Grow Calendula

Calendula does not require a big dose of additional nutrients to have a continuous bloom cycle. In fact, in fairly rich and well draining soils, the plant performs well without much additional fertilizing at all.

A light monthly dose of all-purpose fertilizer is more than enough to power plants to full blooms. A simple side dressing of fresh compost can also be used to provide a bit of slow-release nutrients to plants.

Deadheading – How To Grow Calendula & Keep It Blooming

If there is one thing that will keep calendula from blooming all summer, it’s leaving old flowers on the plant. Regular deadheading is a must to keep new blooms coming on.

To save the seeds from year to year, allow a few calendula flowers to dry completely on the plant. Then, simply remove and separate the seeds from the flower shell.

When left in place, old flowers steal valuable nutrients from the plant. Nutrients that are vital to help the plant concentrate on forming new stems and blooms.

For maximum blooms, pinch or cut off old blooms and their flowering stems every few days. Remove as much of the stem behind the flower as you can down to the foliage canopy.

End Of Season Maintenance – How To Grow Calendula

With simple deadheading and minimal care, calendula will continue to bloom right up until the first frost. Although it is technically a perennial (Zone 9 through 11), for most areas, it can simply not survive the winter.

Plants can be covered to withstand a few late season frosts, but will eventually succumb to a hard frost or freeze. Once this occurs, plants can be pulled and composted.

You can easily save the seeds of calendula to plant again the following season. To save seeds, simply allow a few of the late season flowers to remain on the plant until completely dry.

Once the flower heads have dried out, simply cut the bloom free and remove the seeds by rubbing the flower head with your fingers. Simply store seeds in a cool, dark and dry area indoors, and then plant again the following spring.

Here is to growing calendula in your landscape, and experiencing the incredible beauty of this unique and versatile herbaceous plant. It truly is a great alternative to create a new look for your flowerbeds, containers and baskets!
