Laxmann's Milk Vetch

Laxmann's Milk Vetch (Astragalus laxmannii var. robustior) should be watered thoroughly about every 2 weeks in the spring and summer. During these seasons, the plant should receive 1 inch of water per week. If the soil is light and sandy, more frequent watering (roughly every 5 days) is advised. In the autumn, the watering should be reduced to about every 3 weeks. During winter, Laxmann's Milk Vetch should be watered only once per month, or less often if the soil is not completely dry. The soil should also be kept slightly moist between waterings, but should not be soggy.

Laxmann's Milk Vetch (Astragalus laxmannii var. robustior) requires 6-8 hours of direct sunlight every day. Sunlight should be direct and intense for optimal growth. The best time of day for providing sun for this species is during the mid-morning and late afternoon hours, avoiding too much exposure during the hottest part of the day (roughly between 10 am and 4 pm). This species is tolerant of partial shade, but will not produce as much growth and blooms under those conditions.

Laxmann's Milk Vetch (Astragalus laxmannii var. robustior) should be pruned regularly throughout the growing season, from late spring through late fall. Pruning should be done selectively, focusing mainly on dead or damaged branches and any suckers that arise. Prune back stems to reduce height if desired, cutting back to healthy buds or to a side branch. Pruning can also encourage branching out for a denser, bushier look. Winter pruning is not necessary for this species, but if desired, wait until late winter or early spring before cutting back any frost-damaged foliage. Pruning at this time should not impact flowering, since Laxmann's Milk Vetch blooms on new growth.
