Plant Spring Torch Heather in well-drained, acidic soil with full sun to partial shade. Space plants about 18-24 inches apart. Water regularly to keep the soil consistently moist, especially during dry spells. Fertilize in early spring with a balanced, slow-release fertilizer. Prune lightly after flowering to maintain shape and encourage bushiness. Protect from harsh winter winds and extreme cold with a burlap wrap if necessary.
