Growing Liatris, also known as blazing stars, can add vibrant color and texture to your garden throughout the growing season. Proper fertilization is essential for healthy growth and abundant blooms. This month-by-month guide will help you optimize your Liatris care year-round.
Early Spring (March – April)
As new shoots begin to emerge, prepare your soil by adding a balanced, slow-release fertilizer. Incorporate organic matter like compost or well-rotted manure to improve soil fertility. This helps establish strong roots for the upcoming growing season.
Apply a light dose of fertilizer around the base of each plant, avoiding direct contact with the emerging shoots. This early feeding encourages healthy development and sets the stage for vigorous growth.
Late Spring to Early Summer (May – June)
As Liatris plants grow taller and begin to bloom, it’s time for a boost of nutrients. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. Apply every 4-6 weeks to support continuous flowering and strong foliage.
Ensure even coverage around the base of the plants and water thoroughly after each application to help nutrients penetrate the soil.
Mid to Late Summer (July – August)
During the peak flowering period, avoid over-fertilizing to prevent excessive foliage growth at the expense of blooms. Instead, apply a low-nitrogen fertilizer to maintain bloom production and plant health.
If your soil is rich, a simple side-dressing of compost or organic fertilizer can provide necessary nutrients without overwhelming the plants.
Fall (September – October)
As the growing season winds down, reduce fertilization frequency. Focus on helping the plants prepare for dormancy by ensuring they are healthy and well-nourished.
Apply a light layer of compost around the base to protect roots and provide nutrients for the following year. Avoid high nitrogen fertilizers late in the season, as they can encourage tender, frost-sensitive growth.
Winter (November – February)
During winter, Liatris is dormant. No fertilization is necessary. Focus on protecting the plants from harsh weather by mulching around the base if you live in a cold climate.
Resist the temptation to fertilize during dormancy, as this can stimulate unwanted growth that may be damaged by frost.
