Light Requirements
Ononis microphylla L.f. prefers full sun exposure to flourish. This plant can grow in partial sun exposure but may not develop its maximum potential. Full sun exposure provides this plant with the necessary energy to develop properly.
Temperature Requirements
This plant species grows well in a mild to warm temperature range. The optimal temperature range for Ononis microphylla L.f. growth is between 15-25°C. At temperatures below this range, the plant may not develop as well, while above it, the plant experiences leaf drop, reduced growth rate, and stunted development.
Soil Requirements
Ononis microphylla L.f. thrives in well-drained soils with a pH range of 6.0-7.5. The plant species prefers soils that are rich in organic matter and have good moisture retention, though they should have a reasonable drainage rate. Ononis microphylla L.f. can grow in a variety of soil types but prefers sandy loams and clay loams.
Cultivation methods
Ononis microphylla L.f. commonly known as little-leaved restharrow, is a perennial subshrub species. It's native to the Mediterranean region and North Africa. This plant species is a hardy and drought-tolerant species, which means it can grow in a wide range of soils. They are easy to grow and require low maintenance.
The ideal location to grow Ononis microphylla is in a sunny and well-drained spot, preferably in a sheltered position. When planting, ensure that the planting hole is twice as big as the root ball. After planting, water the plant thoroughly to help establish the roots.
Watering needs
Ononis microphylla requires minimal watering and can survive long periods of drought. However, it's essential to water the plant during the first growing season to establish the roots. Once established, the plant can withstand dry spells, and supplementary watering might not be necessary.
In case of drought, water the plant deeply and less frequently to ensure that the roots receive enough moisture. Avoid overwatering Ononis microphylla since this can lead to root rot and waterlogging.
Fertilization
Ononis microphylla doesn't require high levels of nutrients to thrive. For healthy growth, it's advisable to add mature compost or well-rotted manure to the planting hole before planting. This will provide the plant with enough nutrients to get established and grow healthy shoots.
It's also advisable to top-dress the plant with a nitrogen-rich fertilizer like blood meal during the growing season. This will encourage lush foliage growth and improve the plant's overall health.
Pruning
Pruning Ononis microphylla isn't necessary, but it's advisable to do so to encourage bushy growth and prolong its flowering period. The ideal time to prune the plant is during spring when new growth emerges.
When pruning, use a sharp and clean pair of shears and cut the stems back by about half their length. This will encourage the plant to produce new shoots from the base, thus promoting bushy growth. Deadheading the spent flowers will also encourage the plant to produce more flowers, thus prolonging the flowering period.
Propagation of Ononis microphylla L.f.
Ononis microphylla L.f. can be propagated by several methods, including seed, root cuttings, and layering.
Propagation by Seed
Seeds of Ononis microphylla L.f. should be collected when they are mature in autumn. The seeds can then be sown immediately into a well-draining seed compost and watered lightly. The seedlings should appear within a few weeks, and they can be transplanted into individual pots once they have developed their first true leaves. Once the seedlings are established, they can be planted into their final positions in the spring.
Propagation by Root Cuttings
Ononis microphylla L.f. can also be propagated by root cuttings. In late autumn or early winter, select a healthy stem and carefully dig around the base of the plant to expose the roots. Cut off a section of the root system, about 5-10 cm in length, and plant it in a well-draining compost. Water the cutting well and place it in a warm, sheltered spot. Within a few weeks, the cutting should start to produce new growth.
Propagation by Layering
Layering is another propagation method that can be used for Ononis microphylla L.f. Choose a flexible stem that is close to the ground and gently scrape the bark away on the underside of the stem. Bury the scraped area in soil, leaving the top of the stem exposed. Hold the stem in place with a U-shaped staple or a small stake. Keep the soil moist, and within a few months, roots should have formed at the buried area. Cut the rooted stem away from the parent plant and replant it in its new location.
