Light Requirements
Liatris ohlingerae requires full sun to partial shade for the best growth. Full-sun exposure is recommended for at least 6 hours daily, which allows for optimal flowering and fruiting to occur. However, this species can tolerate partial shade and still produce flowers but in smaller amounts and with less intensity.
Temperature Requirements
The optimal temperature range for Liatris ohlingerae growth is between 60 and 80 degrees Fahrenheit. This species can tolerate a wide range of temperatures, including short periods of frost, provided the ground does not freeze. However, it is not recommended to cultivate this plant in areas with frequent or prolonged periods of temperatures below 25 degrees Fahrenheit.
Soil Requirements
Liatris ohlingerae prefers well-draining, moist, and fertile soils. The ideal pH range of the soil should be between 5.5 to 7.5. The plants can grow well in sandy, loamy, or clay soils, provided they are not waterlogged. This species does not require consistent watering, but the soil should be kept moist to aid growth during times of dry dates.
Cultivation Methods
Liatris ohlingerae is a hardy perennial plant that thrives in full sun and well-draining soils. To cultivate this plant, you need to start by preparing the soil. Dig up the soil to a depth of about 6 inches to loosen it and remove any debris. If the soil is heavy or compacted, consider adding organic matter such as compost to improve aeration and drainage.
Plant Liatris ohlingerae in early spring or early fall when temperatures are mild to allow the plant to establish before the heat of summer or the cold of winter. The plant grows from a bulb, so make a hole twice the size of the bulb and plant it at about two inches deep and six inches apart from each other.
After planting, water the bulbs well to help them settle in the soil. Liatris ohlingerae requires minimal care once established, and it can self-seed and naturalize in your garden if left undisturbed.
Watering Needs
Liatris ohlingerae is drought-tolerant and thrives in well-draining soils, making it a low-maintenance plant. Water the bulbs immediately after planting to help them settle in the soil. Thereafter, water sparingly and only when the soil is dry to the touch. During periods of drought or extreme heat, consider watering the plant regularly to keep it healthy and happy.
Fertilization
Liatris ohlingerae is not a heavy feeder, and you can manage without fertilizing the plant. However, if you wish to boost the plant's growth, you can apply a balanced fertilizer once a year, ideally in early spring before the plant comes out of dormancy. Use a slow-release fertilizer that will gradually release nutrients over several months, helping to prevent over-fertilization or burning of the leaves.
Pruning
Pruning Liatris ohlingerae is an optional task. Deadheading the spent flowers helps to promote prolonged blooming and improve the plant's appearance. Trim the stem with a clean and sharp pair of pruning shears above the nearest bud or leaf. Prune back the foliage in late fall when it starts to die back naturally; this helps to prevent any disease or pest infestations and prepares the plant for the next growing season.
Propagation of Liatris ohlingerae
Liatris ohlingerae (Blake) B.L. Robins., commonly known as Ohlinger's blazing star, is a herbaceous perennial plant that belongs to the Asteraceae family. This plant is native to the United States and grows well in regions that experience moist, well-drained soil and partial to full sun exposure. Liatris ohlingerae is generally propagated by seeds, root division and stem cuttings.
Propagation by seeds
Propagation of Liatris ohlingerae by seeds is an easy, inexpensive way to propagate this plant. The seeds of Liatris ohlingerae require stratification for successful germination. The process involves chilling the seed in the refrigerator for a few weeks, which simulates the natural wintering process. After stratification, the seeds should be sown in well-drained soil and kept moist until germination takes place. Germination can take between 20 and 30 days, and the seedlings should be transplanted after they have developed at least two true leaves.
Propagation by root division
Propagation by root division is another effective way to propagate Liatris ohlingerae. To propagate Liatris ohlingerae by root division, dig up an established plant in early spring or fall and divide the root ball into several sections. Each section should contain a portion of the root system and a stem. The divided plants should then be replanted in a prepared bed with well-drained soil. Water the plants thoroughly after replanting and continue to keep the soil moist until the plants become established.
Propagation by stem cuttings
Propagation by stem cuttings is also possible with Liatris ohlingerae. The best time to take cuttings is in the early spring when new growth appears. Take a 4-6 inch cutting and remove the bottom leaves. Dip the cut end in rooting hormone, then plant the cutting in a pot with a well-draining soil mixture. Water the cutting well and cover it with a plastic bag to create a humid environment. Place the pot in a warm, bright area with indirect sunlight and keep the soil moist. In about 4-6 weeks, the cutting should have enough roots to be transplanted to a permanent location.
Disease Management for Liatris Ohlingerae
Liatris ohlingerae is known for its resistance to various diseases, but it is still susceptible to some common fungal and bacterial diseases.
One of the most common diseases that affect this plant is powdery mildew. This infection is seen as a white or gray powdery coating on the leaves. To control the spread of powdery mildew, it's important to maintain good air circulation around the plant. If the plant is already infected, fungicides can be used as a last resort.
Anthracnose is another disease that can affect Liatris ohlingerae, causing brown spots on the leaves. To prevent this disease, avoid overhead watering and remove any affected leaves and stems immediately.
The bacterial disease, Xanthomonas, can cause yellowing and wilting of leaves, as well as stem cankers. There is no effective treatment for this disease, so it's essential to remove any infected plants and disinfect garden tools.
Pest Management for Liatris Ohlingerae
Liatris ohlingerae is relatively resistant to pests, but some common garden pests can still damage the plant.
Aphids are one of the most common pests that affect Liatris ohlingerae. They are small, green or black insects that can cause yellowing and curling of leaves. To control aphids, blast the infested plants with a strong jet of water or use an insecticidal soap solution.
Spider mites are another pest that can affect this plant. They are tiny, red or brown insects that thrive in hot, dry weather. To control spider mites, spray the plants with water regularly or use a miticide.
The Liatris ohlingerae root weevil is a pest that can damage the roots of this plant. This pest can cause wilting, yellowing, and stunted growth. To prevent an infestation, apply a soil drench with imidacloprid in the spring and fall.
