Organise the framework before new growth; shorten long side shoots selectively after a flowering flush.

Guidance for Germany and Central Europe. Position, weather, species and cultivar shift these windows; indoor and container plants also depend on their winter conditions.

Your seasonal care plan

  • Check moisture

    Jan · Feb · Mar · Apr · May · Jun · Jul · Aug · Sep · Oct · Nov · Dec

    Water thoroughly during warm active growth and let excess drain. Check the upper compost before watering again; use much less in cool winter quarters without letting the root ball dry completely.

  • Feed active growth

    Apr · May · Jun · Jul · Aug · Sep

    Account for existing nutrition and root condition. Exact dilution and application limits are given with the linked product. Dilution: 5 ml per 1.5 litres of water. Every 1–2 weeks during active growth. April–September.

    View product dosage and application →

  • Prepare the root space

    Mar · Apr · May

    Choose timing by species and growth, checking medium and drainage. Follow the full instructions for the linked growing medium.

  • Care through winter

    Oct · Nov · Dec · Jan · Feb · Mar

    Move to bright winter quarters before frost; reduce watering but keep checking root-ball moisture.

Highlighted months are guidance, not fixed dates. Observe the plant, root ball and weather; water, feed and repot according to actual need.

Fruit & harvest

Fruit and seed formation

The colourful papery structures are bracts, not fruits. The true flowers are small; pollination can produce an inconspicuous narrow dry fruit.

Harvest and use

Not normally harvested for food. Container cultivation focuses on the colourful bracts. Seed set is unnecessary for continued growing; vegetative propagation is used to retain cultivar characteristics.

Plant knowledge at a glance

Position, benefits & character

Position & soil

Sunny, warm and sheltered. A freely draining pot and aerated medium make moisture easier to manage.

Distinctive features

Showy colour comes from bracts. The small true flowers often occur in groups of three.

Benefits

A flowering trellis creates a strong colour accent on a terrace or balcony.

Partners & symbioses

The small flowers can feed insects. Normal container culture does not require adding a particular symbiotic partner.

Pruning & growth habit

Retain strong main shoots on the support and identify crossing or dead growth.

  1. 1. Choose a framework

    Retain strong main shoots on the support and identify crossing or dead growth.

  2. 2. Direct side shoots

    Cut back to a suitable branch with clean tools, taking care of the thorns.

  3. 3. Keep light in the centre

    Tie new shoots loosely and avoid a congested tangle; allow weakened plants to recover first.

Nursery forms

This overview explains nursery supply forms. It does not indicate current availability in the GREEN24 shop.

Bare-root

Ask a specialist nursery

Bare-root availability depends on species and season. Protect fresh roots from drying before planting.

Root-balled

Ask a specialist nursery

Root-balled stock mainly for larger woody plants; keep the ball together until planting.

Container-grown

Common form

Rooted pot or container stock; inspect plant and root ball before buying.

Young plant

Common form

Young plants allow early shaping but need time to establish.

Shrub

Common form

Choose bushy multi-stem forms according to natural habit and available space.

Feathered tree

Ask a specialist nursery

Low-branched or feathered trees only where appropriate for the woody species.

Half-standard

Ask a specialist nursery

Half-standard with a distinct crown, depending on species and availability; check stem and crown attachment.

Standard

Ask a specialist nursery

Standard forms need enough room and suitable stability.

Topiary

Ask a specialist nursery

Topiary needs regular species-appropriate maintenance; the shape is not a species name.

Propagation & grafting

Propagation

Semi-ripe cuttings can root in warm, protected conditions; seed does not reliably preserve cultivar traits.

Grafting

Usually propagated vegetatively. Multi-coloured grafted plants are possible; check the label and graft unions.

Species & cultivars

Bougainvillea glabra

Smaller leaves; often used for container and bonsai forms.

Bougainvillea spectabilis

Vigorous growth, often noticeably hairy leaves; allow enough room.

Hybriden

Colour, vigour and flowering habit vary; retain the cultivar label.

Pests & diseases

These signs support an initial assessment. Different causes may look alike; choose a treatment only after identifying the problem.

Position & water first

Sunny, warm and sheltered. A freely draining pot and aerated medium make moisture easier to manage.

Recognise pests

Check young shoots for aphids and leaf undersides for mites or scale.

Assess damage

With persistent wetness, inspect roots and drainage; extra feed is not a treatment for soft dark roots.

Hardiness · USDA

USDA describes climate using long-term winter minima, not a safe frost limit for an individual root ball.

Bougainvillea
USDA 9b–10bSpecies example; account for cultivar, age and site.

USDA zones describe long-term average winter extremes. Containers, young plants, wet soil, wind and late frost need separate consideration.
