Once established, it can withstand moderate drought periods due to its adaptation to its native habitats. However, a deep watering regime in summer helps to maintain the plant's appearance and resilience in the garden.
Fertilizers: This plant can survive without fertilizers, but a light application of organic fertilizers helps maintain healthy growth.
Propagation: Conostylis candicans can be propagated by division, seed, or tissue culture. The best time to propagate this plant is during early autumn or early spring, where there is adequate warmth and moisture.
Cultivation methods for Conostylis Candicans
Conostylis Candicans grows well in sunny and well-draining soils. It is a hardy plant that can survive in different soil types, including sandy soils, clay soils, and loamy soils. It is also drought-tolerant, and that is why it is a perfect plant for xeriscaping. To grow Conostylis Candicans, ensure you plant them in areas where it can receive enough sunlight.
Watering Needs for Conostylis Candicans
Water Conostylis Candicans regularly especially during the growing seasons. However, it is essential to note that this plant is drought-tolerant, and it can survive long periods without water.

Fertilization of Conostylis Candicans
Conostylis Candicans does not require regular fertilization, but you can apply a slow-release fertilizer once a year during the growing season. Use a balanced fertilizer that has equal amounts of nitrogen, potassium, and phosphorus. Over-fertilization can lead to excessive foliage growth at the expense of flowers.
Pruning of Conostylis Candicans
Conostylis Candicans does not require intensive pruning since it is a low-maintenance plant. However, you can deadhead the flowers to encourage more blooms. You can also trim the foliage once in a while to keep the plant tidy and to remove any dead or damaged leaves. Avoid pruning during winter since this is when the plant is dormant.
Propagation of Conostylis Candicans
The Conostylis candicans, also known as grey cottonhead or grey velvet, is a beautiful plant with a stunning display of silver-grey foliage and bright yellow flowers that bloom between August and October. If you plan to expand your garden, you can reproduce this plant through propagation.
Propagation through Division
The division is the most common method of propagating the Conostylis candicans. You can divide the plant every two to three years. The best time to divide the plant is during the spring, once new growth starts to appear.
You can start the propagation process by removing the plant from the pot or garden bed and shaking off excess soil. Then, you have to gently divide the plant's roots with a clean, sharp knife, ensuring that each division has a healthy portion of the root system and foliage.
Once you have divided the roots, immediately pot or plant each division in a well-draining soil mix. For potted plants, use a pot that is slightly larger than the root ball to accommodate for future growth.
Propagation through Seed
Propagation through seed is another option for the Conostylis candicans. The best time to harvest the seed is during autumn when the flowers fade, and the seeds start to dry and turn brown.
Once you collect the seeds, you have to prepare them for planting by removing the husks and any chaff. Then, plant the seeds in well-draining soil, burying them at a depth of about two times their size. Keep the soil surface moist and ensure that the seed tray is in a warm, well-lit location.
After the first set of true leaves emerge, it is time to transplant the seedlings into individual pots or garden beds. Make sure the new location provides well-draining soil, plenty of sunlight, and enough space for future growth.
Propagation of the Conostylis candicans through division and seed are both reliable methods of expanding your collection. By following these propagation methods, you can enjoy the beauty of this plant and enjoy it for years to come.
Disease and Pest Management for Conostylis Candicans Plants
Conostylis Candicans, also known as the grey cotton head plant, has a reputation for being relatively disease and pest-resistant. However, the following are some of the common disease and pest problems that affect the plant and ways to manage them:
Diseases
Fungal diseases such as leaf spot, rust, and root rot are the most common diseases that affect Conostylis Candicans plants. These diseases result in yellow, brown, or black spots on the leaves and stems, wilting, and in severe cases, death of the plant.
To manage fungal diseases, start by removing the affected leaves and stems. Then, applying a fungicide that contains copper oxychloride, mancozeb, or thiophanate-methyl on the healthy parts of the plant can help stop the spread of the disease.
Pests
Conostylis Candicans plants are susceptible to attack by mealybugs, aphids, and spider mites. These pests feed on the sap of the plant, causing stunted growth, yellowing of leaves, and eventually, death of the plant.
To manage pest infestations, start by washing the affected parts of the plant with a strong jet of water to dislodge the pests. Then, apply insecticides that contain neem oil, pyrethrin, or insecticidal soap to eliminate any remaining pests.
Regularly inspecting your plants for any signs of diseases or pests, and taking prompt measures to manage them, is the best way to keep your Conostylis Candicans plant healthy and thriving.
