Fertilizing Lungwort

Fertilizing perennials like Lungwort supports a healthy growth rate. Plants need help getting the nutrients that are not always available in a manicured bed, mixed planting, or container. Lungwort plants prefer rich soil, and they respond well to a boost of nutrition via organic mulch. Fertilizing helps Lungwort growth, but too much plant food can be a problem. Overfeeding Lungwort plants can cause the plant to drop flowers or not bloom at all. Fertilizing is helpful, but learning when and how to fertilize Lungwort is essential to support healthy plants that thrive and bloom.


How to Fertilize Lungwort

When planting, the best way to support Lungwort is to amend the soil with manure or organic compost. In each year that follows, apply a layer of organic compost around the base of the plant to hold in moisture and give the plant some extra nutrition. Lungwort plants are not heavy feeders, but a water-soluble fertilizer is a great way to feed the plant easily. Slow-release fertilizers are another option and will deliver nutrition more slowly to the roots over several months or more.

Best Time To Fertilize Lungwort

Feed Lungwort in the spring to support new growth. Herbaceous Lungwort can be fed when new growth emerges from the ground. Evergreen Lungwort can be fertilized when buds appear on the plant. One annual feeding is enough to support Lungwort throughout the entire growing season. Overfeeding can be harmful to the plant.

Best Fertilizer For Lungwort

Use a balanced fertilizer for Lungwort. A product with an NPK ratio of 10-10-10 or similar is a good choice to support roots, foliage, and flowers. Water-soluble fertilizers can be applied when watering the plant for ease of use.
