PLACEMENT & CULTIVATION
Cheerful bells bloom along the tall stalks of this cottage garden classic. Bloom starts in early summer with columbines, foxgloves, lady's mantle, and other perennials that thrive in dappled sun. Cut back the flowering stems once flowering is over, but leave foliage over the winter months, tidying up in spring if needed. They suffer in prolonged heat and humidity but are cherished flowers for northern gardens or wherever summer nights cool down. Perfect for woodland edges and gardens that get some afternoon shade. Leave a few stalks to drop seed or divide in spring or after flowering every three years.
Watering Details:
These plants prefer evenly moist soil, so be sure to water if the ground becomes dry. About an inch of water per week, more may be necessary during particularly dry spells.
Soil pH:
Does best in a soil with a neutral to slightly alkaline pH level.
Fertilizer:
Prior to planting, mix a few inches of compost into the soil. Topdress annually.
Diseases & Pests:
Slugs or snails may occasionally be an issue, but a preventive application of pelletized iron phosphate or diatomaceous earth when these creatures are present will keep the plants safe. Avoid wet soils in winter, a well-drained soil helps avoid crown rots.
When to Cut for Bouquets:
Harvest when 1/2 of the flowers on a stem are open.
