Othonna Capensis Little Pickles Plant Care
Othonna Capensis Size & Growth:
The size, shape and growth rate of Othonna plants vary. This succulent groundcover spreads quickly and easily in its hot, dry native environment.
Most plants grow no more than two inches tall and spread to be about eight inches wide. This is a quick growing plant.
Little Pickles Ruby Necklace Flowering & Fragrance:
For the most part, “Little Pickles” plants produce very small, dainty, yellow daisy flowers.
The yellow flowers stand above the foliage on long, slim stems. Sometimes the flowers may be purple or white.
The fragrant blossoms are attractive to a wide variety of pollinators including butterflies, bees and other insects.
Flowering time may vary from one location to another, but generally speaking these plants bloom from late in the spring to early in the autumn (May through October).
Othonna Foliage & Growth Habit:
Othonna capensis has very succulent leaves and grows in a spiral pattern around long, slim pink, purple or red stems.
Depending on the setting and nutrients available, leaves may vary in length from a quarter-inch to four inches long. The green leaves are fingerlike (or pickle like if the plant’s common name is to be believed) and blue-gray in color.
What Light Conditions & Temperature Does Othonna Capensis Grow Best In?
Capensis plants do well in lighting ranging from partial shade to full sun. However, the Othonna plant does not like extended exposure to very hot sunlight, but does well in the morning sun.
The succulent Othonna little pickles are recommended to grow outdoors year-round in USDA hardiness zones 9a through 11.
The leaves remain stiff and blue-gray when growing ruby necklace plants in full sun or in only partial shade. Too little sunlight causes the leaves to become greener, very thin, stretched, and floppy. Capensis also does well under a grow light.
Watering Needs & Feeding of String Of Pickles Plant
Highly drought tolerant, these water-wise plants, like most succulents, prefer occasional deep watering. Allow the soil to dry almost completely between waterings.
Water throughout the growing season and reduce watering during the plants’ dormant time.
Fertilizer is optional. If you do fertilize, use a very weak solution of a liquid cactus or succulent formula.
Soil & Transplanting Othonna:
The Ruby necklace does very well in a sharply well-draining soil mix. A good mix for Othonna consists of equal parts coarse sand, vermiculite, and organic material.
Little Pickle Plant Grooming & Maintenance:
Deadhead flowers on “little pickle” plants regularly throughout the blooming season to encourage more blossoms. Trim and pinch back the stems to maintain the shape you prefer. Remember to save cuttings to grow new plants.

How To Propagate Little Pickles Succulent
Cuttings are the easiest way to propagate the capensis plant. The plant grows rampantly in its native setting, and growing it from stem cuttings is quite simple.
You can literally pinch a cutting from a ruby necklace, poke it into the soil of a neighboring pot and wait.
Little Pickles Succulent!
To grow from seed, start the seed on the surface of a well-draining soil in the springtime when the temperature is reliably 64° to 70° degrees Fahrenheit.
As with most succulent seeds, keep the growing medium slightly damp and protect the seedlings from extremes in temperature and exposure until they become well established.
Pest or Disease Problems On Ruby Necklace Plants
Othonna is carefree and establishes itself quickly in almost any soil that provides sharp drainage. Poor drainage is sure to cause root rot and problems with disease.
Like most succulents, when kept as a houseplant Othonna is susceptible to pests that are common to succulents, such as:
- Spider mites – How does spider mite infestation damage my succulents?
- Fungus gnats
- Mealybugs – What signs should I look for on a succulent infested with mealybugs?
- Plant Scale – What damages does scale cause to succulents?
Follow “Best Practices”, such as:
- Keeping new plants in quarantine
- Avoiding overcrowding and overwatering
- Provide good ventilation
- Use appropriate insecticidal products as needed to keep these pests at bay.
Is Othonna Succulent Invasive?
In its native settings, Othonna capensis plants grow with wild abandon. If you live in areas where the plant is winter hardy, be careful not to allow Othonna to ramble off freely. It has a rapid growth rate.
Naturally, in settings where the ruby necklace will die back during the winter it is not invasive. Likewise, if you keep it as a houseplant it will not have the opportunity to be invasive.
