Light Requirements
Helichrysum rutilans is a sun-loving plant that thrives in maximum sunlight. This plant requires full sun exposure to grow and flourish. A minimum of 6 to 8 hours of direct sunlight is essential for its growth and development. It is recommended to plant Helichrysum rutilans in an unobstructed location where it can receive maximum sunlight throughout the day.
Temperature Requirements
Temperate climate and moderate temperatures are ideal for the growth of Helichrysum rutilans. It is a plant that can tolerate extreme heat to some extent. The best temperature range for this plant is from 20°C to 30°C. Lower temperatures of around 15°C can slow down its growth. This plant cannot survive temperatures below 0°C or frost, and hence, it is not suitable for regions with colder climates.
Soil Requirements
Helichrysum rutilans prefers growing in well-draining, moderately fertile soil. The soil should have a neutral to slightly acidic pH ranging from 6 to 7.5. It can also grow in sandy and loamy soil types. However, the soil should not be too compact as it can lead to poor drainage, which is not suitable for this plant's growth. The soil should have a good amount of organic matter that can provide the necessary nutrients essential for the plant's growth. It is also recommended to avoid heavy clay soils as they retain water for too long.
Cultivation Methods
Helichrysum rutilans (L.) D.Don, also known as the sticky everlasting or the red everlasting, is a perennial plant that is native to Argentina, Bolivia, and Chile. To cultivate this plant, it is essential to provide it with well-draining soil and full sunlight. The soil should be loamy and slightly acidic, with a pH range of 6 to 6.5. It is advisable to mix the soil with organic matter such as compost to improve its fertility and soil structure. The plant can be propagated through seeds or cuttings. Sow the seeds in early spring or fall when the temperature is around 68-77°F. The seeds take about 2 to 3 weeks to germinate. Alternatively, you can propagate the plant through cuttings. Take a 3 to 4 inches of a healthy cutting from the parent Helichrysum rutilans plant, remove the lower leaves near the stem, and plant it in moist soil. The cutting should root in 3 to 4 weeks.Watering Needs
Watering the Helichrysum rutilans plant can be tricky. The plant requires moderate watering; it should neither be too wet nor too dry. Water the plant deeply once or twice a week, depending on the soil's moisture level. It is advisable to measure the soil moisture level regularly using a moisture meter or by sticking your finger into the soil. If the top inch of the soil is dry, then it is time to water the plant. Additionally, Helichrysum rutilans is susceptible to root rot, so avoid over-watering. Ensure that water does not accumulate near the plant's roots, check that the pot or garden bed has proper drainage.Fertilization
Fertilize the Helichrysum rutilans plant every four weeks during the growing season, which is usually from spring to summer. Use a balanced fertilizer, such as 10-10-10, at half strength, as the plant does not require too much fertilizer. Also, Helichrysum rutilans is sensitive to high levels of nitrogen, so avoid using nitrogen-rich fertilizer. If you are growing Helichrysum rutilans in pots, use slow-release fertilizer that can feed the plant for up to four months. Ensure that you follow the manufacturer's instructions when applying the fertilizer.Pruning
Prune the Helichrysum rutilans plant regularly to maintain its compact growth habit and encourage bushy growth. It is best to prune the plant after it has completed its blooming cycle. Cut back the plant by 1/3 of its total height. However, if the plant is getting too leggy or has dead or damaged stems, you can prune it at any time. Use a pair of clean, sharp pruning shears to remove the unwanted parts of the plant. Avoid pruning the plant too much as it can affect its blooming ability. In conclusion, Helichrysum rutilans is an excellent addition to any garden. With the proper care and cultivation, it produces beautiful, long-lasting blooms that can brighten up your yard or home.Propagation of Helichrysum rutilans (L.) D.Don
Helichrysum rutilans (L.) D.Don, also known as the strawflower, belongs to the Asteraceae family and is native to South Africa. It is a perennial plant that is commonly grown as an annual. To propagate a Helichrysum rutilans plant, there are various methods available that can be used with ease.
Propagation Methods
1. Seed Propagation: This is the most common method used to propagate Helichrysum rutilans. The seeds are small and should be sown thinly in seed trays during early spring (March - April) in good quality seed compost. Cover the seeds lightly with compost, keep the soil consistently moist, and place the trays in a warm and bright area, but not in direct sunlight. Germination usually takes around 14-21 days. Once the seedlings have grown sufficiently, they can be transplanted into individual pots or trays filled with potting soil.
2. Stem Cuttings: Stem cuttings can also be used to start up a new plant. Cuttings taken from healthy plants should be around 7-9 cm long, and the leaves should be stripped away from the bottom half of the stem. Dip the cut end in rooting hormone before planting in well-drained soil. Keep the soil moist and cuttings in bright but indirect light till they take root. Once they have rooted, they can be moved to their own pots.
3. Division: This is an uncommon method of propagating Helichrysum rutilans but is easier than the other two methods. In the spring or fall, divide an established plant by gently separating it from the clump and planting it into another pot. Ensure that the root system is kept moist to avoid the shock of division.
Apart from these methods, Helichrysum rutilans can also be propagated through layering. It can take anywhere from a few weeks to a few months for the new plant to root. Regardless of the method, Helichrysum rutilans requires bright, indirect light and consistent moisture for optimal growth.
