Planting Calendar
Plant Corms
7 Feb – 9 AprPlant corms around 7th February - 9th April, with the growing point just below the surface in firm, well-drained soil. Space them apart and water in thoroughly straight after planting.
Water to Establish
9 Apr – 7 JunKeep the soil evenly moist for the first 9th April - 7th June while the corms root in. Give a deep soak in dry spells, then ease off once new growth is strong and the clump is settled.
Deadhead Spent Stems
24 May – 3 OctFrom 24th May, remove faded flower stems as they finish to keep the plant tidy and encourage a longer display. Cut each stem back to the base once the last flowers on it have gone over.
Cut Back Old Growth
19 Sept – 2 NovAfter hard frost has blackened the leaves, cut the faded foliage to the base during 19th September - 2nd November. Leave any green leaves in place until they die back naturally, because they are feeding next year's growth.

Why companion planting matters
Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.

Basil
Basil is a fragrant, tender herb whose leaves are a staple of summer cooking. Native to tropical regions, basil is treated as an annual in temperate climates like the UK because it cannot tolerate frost. It thrives in warm, sunny conditions and can be grown in garden beds or pots for a steady supply of fresh, flavourful leaves throughout the summer.
Brussels Sprouts
Brussels sprouts are a hardy winter brassica (cabbage family) that form sturdy, leafy stems often around 60–90cm tall. They produce edible mini-cabbage buds along the stem from autumn through winter. Thanks to their cold tolerance, sprouts remain productive into late winter, and frost actually improves their sweetness.
Calabrese
Calabrese (broccoli) produces a large central head of tightly-packed green buds, followed by smaller side-shoots after the main head is cut. It’s a cool-season brassica crop. Grow it in full sun with fertile, well-drained soil and keep plants watered during dry spells. Harvest the heads while firm, then leave the stem in the ground to allow side-shoots to develop.
