Growing Weigela in a pot
For balcony, patio or terrace — Weigela florida
weigela grows well in a pot of at least Ø 70 cm (269 L capacity), in a position with full sun or partial shade. Watering: every 2 days in summer, once every 2 weeks in winter.

Choose a generous pot with good drainage — small pots restrict root development.

Always use a pot with drainage holes. Water dries out faster in pots — or the plant drowns. Check weekly with your finger: only water when the top 2 cm of soil is dry.
Pot care
Weigela has moderate water needs and tolerates short dry spells once established, but performs best with consistent moisture during the growing season. Water deeply during prolonged dry periods in spring and summer, especially while the shrub is flowering and putting on new growth. Reduce watering in autumn and winter; established plants rarely need supplemental water during the dormant months. Avoid overhead watering, which can encourage fungal issues on the foliage. Feed in March and again in April with a general-purpose balanced fertiliser such as blood, fish and bone or a controlled-release granular feed, scattering it around the base and watering in if the soil is dry. Alternatively, apply a mulch of well-rotted compost or manure in early spring, which feeds the soil and helps retain moisture. Avoid high-nitrogen feeds after May, as soft late growth is more vulnerable to frost damage. Weigela is fully hardy across temperate Europe (zone 4a–8b) and requires no winter protection. Mulch around the base in autumn to insulate roots and suppress weeds, but keep it clear of the stems. Common pests include aphids, which cluster on soft new shoots in late spring; a strong jet of water or an insecticidal soap usually controls them. Leaf spot and powdery mildew can occur in humid conditions or on congested plants—good airflow through annual pruning minimises the risk. Remove and bin any affected leaves. Maintenance is otherwise minimal; weigela is a robust, undemanding shrub that rewards basic care with a reliable display of pink or red flowers each year.
Pot-specific tip: add slow-release fertiliser pellets in March — potting soil exhausts much faster than open ground.
Heads-up — large plant: this weigela grows up to 200 cm tall. A 60-70 cm pot works for the first 3-5 years; after that the rootball outgrows it. Plan to transplant into the garden, or pick a compact cultivar for permanent pot culture.
