Least Bladdery Milk Vetch

The least bladdery milk vetch (Astragalus microcystis) is a drought-tolerant, perennial herb that grows in sunny, dry sites. This species requires minimal and infrequent watering. Most soil types are acceptable as long as the soil is well-drained. Water the plant deeply but infrequently, every 3-4 weeks during the growing season. In autumn, stop watering unless the plant is in an area that receives little rain. Reduce watering even further in winter and withhold entirely during periods of extreme cold. If grown in containers, monitor the soil moisture and water as needed if the soil starts to dry out. Over-watering can cause root rot and lead to plant death.

Least Bladdery Milk Vetch (Astragalus microcystis) is a sun-loving annual plant species and requires 6-8 hours of direct sunlight each day to be able to thrive and flower. It is best to place this species in a location that receives full sun in the morning and afternoon, with some light shade providing protection from the direct rays of the sun during the hottest midday hours. This species prefers to be grown in a sunny spot with at least 6-8 hours of full sun each day and should be given some afternoon shade. It is important to watch out for too much hot midday sun as this can be damaging to the foliage of this species. With the right location and adequate sunlight, Least Bladdery Milk Vetch will produce abundant flowers.

Least Bladdery Milk Vetch (Astragalus microcystis) should be pruned in late winter or early spring, when the plant is still dormant. Pruning should be limited to removing dead, dying, or damaged branches, and thinning out the canopy to encourage better air circulation and light penetration. Avoid excessive pruning, as it can damage the plant's root structure and lead to poor growing conditions. If necessary, add a light fertilization program to promote strong growth.
