lupine

Lupine (Lupinus 'Manhattan Lights') is a hardy, attractive perennial that can flourish in most soils. Watering for this plant species should be done regularly, but in moderation. The soil should remain slightly moist but never saturated. During the summer months, water your Lupinus 'Manhattan Lights' at least once a week, though more frequent watering may be necessary if there is an extended period of heat or winds, or if the plant is planted in a container. During the cooler months, reduce the frequency of watering to once every 2 weeks. Avoid over-watering or letting the soil become soggy, as both can lead to root rot. Wilting leaves may be a sign that too little water is being provided.

Lupines need full sun to partial shade to thrive. This particular variety, 'Manhattan Lights', should receive at least 6 hours of daily direct sunlight for optimal growth. For best results, the plant should receive direct sunshine during the morning hours and be shaded from the hot afternoon sun. If the plant receives too much direct sunlight, it can burn and the blooms may suffer. When in full sun, Lupinus 'Manhattan Lights' should be watered regularly.

Pruning Lupinus 'Manhattan Lights' should be done annually in late winter or early spring before new growth begins. Pruning should be minimal, as this particular species of lupine has an attractive shrub form that should be maintained. Any overly long or unsightly stems should be pruned, and any dead, damaged, or diseased stems should be removed. Overly-crowded areas can also be thinned to encourage fuller, healthier growth. For aesthetic purposes, minor shaping can be done to create a more uniform appearance. If pruning is done regularly, the bloom size and quality should be improved.
