Jones can adapt to different soil types, but it does best in loam or sandy loam soil. Before planting, it is recommended to amend the soil with compost or aged manure to improve its structure and fertility.
Iva nevadensis M.E. Jones can be propagated by seed or through division. If starting plants from seed, the best time to sow is in the early spring. After seed germination, thin out the seedlings to allow them to have enough space to grow. When propagating through division, do so in the fall or early spring before new growth begins.
Watering Needs
Iva nevadensis M.E. Jones is a drought-tolerant plant, and as such, overwatering can lead to root rot. Watering should be done only when the soil is dry to touch. During the plant's growing season, water deeply once a week. In winter when the plant is dormant, water sparingly to prevent the soil from completely drying out.
Fertilization
Iva nevadensis M.E. Jones will benefit from light applications of fertilizer during its growing season, which is from spring to summer. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer at half strength to avoid over-fertilization, which can lead to leggy plants and reduced flowering.
Pruning
Pruning Iva nevadensis M.E. Jones is not required, but it can help to maintain the plant's shape and promote bushier growth. Cut back the plant by one-third of its height in the early spring before new growth begins. Deadhead spent flowers to encourage the growth of new flowers.
Propagation Methods of Iva nevadensis M.E. Jones
Iva nevadensis M.E. Jones, commonly known as Nevada greenthread or Nevada feverfew, is a native herbaceous perennial plant found in the southwestern part of the United States. The plant is drought-resistant and can tolerate a wide range of soils, from sandy to clay loams. Here are the propagation methods for Iva nevadensis M.E. Jones:
Seed Propagation
Propagation by seeds is the most common method for Iva nevadensis M.E. Jones. The plant produces numerous small, cylindrical seeds that are dispersed by wind and insects. Seed propagation can be done indoors or directly in the field.
To start the seeds indoors, you need to clean the seeds and soak them in warm water for a few hours. After that, fill a seed tray with a good quality potting mix and sprinkle the seeds on the mixture's surface. Lightly cover the seeds with more potting mix and water gently. Place the tray in a warm and bright location but out of direct sunlight. The seedlings can be transplanted outdoors when they reach four to six weeks of age.
In the field, you can sow the seeds after the last frost date. Prepare the soil by removing weeds and debris and loosening it to a depth of at least six inches. Sow the seeds by broadcasting them on the soil surface and lightly covering them with soil. Water the soil and keep it moist until the seeds germinate and establish.
Vegetative Propagation
Iva nevadensis M.E. Jones can also propagate vegetatively by cuttings. Take cuttings from the plant's healthy and mature stems and remove the leaves from the bottom two-thirds of the stem. Dip the stem's end in rooting hormone powder and stick it in a potting mix. Water the soil and keep it moist and warm until the cutting roots. After rooting, transplant the cutting to a larger pot or directly outdoors.
Overall, Iva nevadensis M.E. Jones is relatively easy to propagate either by seed or vegetatively by cuttings. With proper care and attention, you can propagate and establish a beautiful and drought-resistant plant in your landscape.
