Aquilegia 'Cardinal'

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water in dry periods

Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.

Spring-Autumn · Planting

Trim dead flowers to prevent self-seeding

Note on self-seeding: If you do not want this plant to set seed it is necessary to promptly remove the spent flowers as they fade.

It's possible to carefully remove the seed heads, complete with seed, and then place them in areas where you would like new seedlings to grow.

Compost · Planting

Multi-purpose compost

Use a good quality peat-free multi-purpose compost when growing in pots and containers.
