How to Grow Fire Weed

Overview

Fire weed (Epilobium angustifolium), also called rosebay willowherb, is a perennial wildflower with smooth leaves and delicate pink flowers. Fire weed grows from 2 to 5 feet tall and does best in full sun and moist soil. This plant becomes dormant during very hot weather, making it ideal for regions with cooler growing seasons. Fire weed gets its name from the tendency it has to grow in recently disturbed soils, such as sites of wildfires or volcanic eruptions.

Step 1

Prepare the planting site by removing all large rocks, weeds and grass. Use a garden fork to loosen the soil to a depth of 3 to 4 inches.

Step 2

Amend the soil with 2 inches of organic compost. Dig a hole that is 2 inches deep. Place the roots of the fire weed plant into the hole and replace the soil. Tamp down firmly and add enough water to moisten the soil well.

Step 3

Continue to water the new planting whenever the soil feels dry. Once the plant is established, watering is only necessary during very dry conditions.

Step 4

Fertilize every two weeks with liquid fertilizer mixed as instructed on the package.

Tips and Warnings

  • Fire weed spreads quickly once established, so it's wise to keep a close eye on it in the garden to keep it from spreading too widely and interfering with the growth of other plants.
