When to plant Weigela?

Weigela florida thrives in full sun or partial shade, though flowering is most abundant in a sunny position. It tolerates a wide range of soils but performs best in loam or clay that retains some moisture without becoming waterlogged. Before planting, dig a hole roughly twice the width of the root ball and fork over the base to improve drainage. Work in a generous amount of well-rotted compost or manure to enrich the soil, especially if it's poor or sandy. Plant bare-root weigelas between March and May or in September and October; container-grown specimens can go in at any time during these windows, though autumn planting allows roots to establish before the growing season. Space plants 160 cm apart to allow for their mature spread of up to two metres. Set the shrub at the same depth it was growing in the pot or nursery—planting too deep can lead to stem rot. Backfill with the excavated soil mixed with compost, firming gently as you go to eliminate air pockets. Water thoroughly immediately after planting, even if the soil feels damp, to settle the roots. Apply a 5–7 cm layer of mulch around the base, keeping it a few centimetres clear of the stems to prevent rot. If planting in spring, water weekly for the first growing season during dry spells. Autumn-planted weigelas need less attention but should be checked during prolonged dry periods in late autumn. Staking is not usually necessary unless the site is very exposed.
