Remove dead stems of deciduous species before new growth; treat evergreen species separately.

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

  • January

    Check standing water and vulnerable containers.

  • February

    Distinguish old stems from early new shoots.

  • March

    Tidy the border without damaging new growth.

  • April

    Plant suitable species and support tall perennials where needed.

  • May

    Check establishing plants and assess nutrient need.

  • June

    Adjust moisture care to weather and species.

  • July

    Check containers and new plantings more often in heat.

  • August

    Observe flowering, seed heads and possible self-seeding.

  • September

    Plan autumn planting of suitable hardy species.

  • October

    Check foliage habit and winter vulnerability by species.

  • November

    Keep container drainage clear.

  • December

    Record the planting and plan next year’s gaps.

  • Feed according to need

    Apr · May · Jun · Jul · Aug · Sep

    Well-nourished borders do not automatically need extra feeding. If required, use Perennial Fertiliser at 5 ml per 2 litres every 1–2 weeks in active growth. Account for nutrients already present; normal 100%, young plants 50%, seedlings with leaves 20% of the standard strength.

Care tips

  • Identify the species before buying or caring for it.
  • Match light and soil to the species.
  • Feed according to actual need.

Fruit & harvest

Fruit and seed formation

Fruit and seed forms differ between plant families.

Harvest and use

Do not assume ornamental perennials are edible. Collect seeds only from clearly identified plants.

Plant knowledge at a glance

Position, benefits & character

Position & soil

Match light, soil and moisture to the actual species. A group name cannot replace site requirements.

Distinctive features

Flowering perennials are not one botanical family. Some die back above ground; others retain foliage.

Benefits

Different flowering seasons and habits allow varied border designs.

Partners & symbioses

Flower visitors and seeds as food vary by species; do not promise a universal pollinator benefit for every cultivar.

Pruning & growth habit

Allow for mature spread and account for runners and competition when combining plants.

  1. 1. Check the growth habit

    Distinguish deciduous and evergreen species.

  2. 2. Cut selectively

    Preserve healthy new shoots when removing old stems.

  3. 3. Plan support

    Support tall species early when necessary.

  4. 4. Consider seed heads

    Account for seed ripening, self-seeding and winter structure.

Nursery forms

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

Container-grown

Common form

Potted perennials are the usual retail form.

Young plant

Common form

Young plants and small pots need time to establish.

Bare-root

Translation missing: en.g24_atlas.occasional

Some species are sold as dormant roots or divisions; check species and planting season.

Root-balled

Feathered tree

Propagation & grafting

Propagation

Seed, division or cuttings may be suitable, depending on species. Consider true-to-type reproduction and plant rights.

Grafting

Grafting is not a standard method for ordinary herbaceous flowering perennials.

Species & cultivars

Sonnenstauden / Sun-loving perennials

Choose the site for the actual species; flower colour does not indicate water needs.

Schattenstauden / Shade-loving perennials

Assess light, root competition and soil moisture separately.

Wintergrüne Stauden / Evergreen perennials

Do not routinely cut to ground level as if all foliage were deciduous.

Pests & diseases

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

Wetness and drought

Check the root zone before attributing leaf changes to nutrient deficiency.

Check feeding damage

Record species and damage pattern; do not choose treatment from one hole in a leaf.

Coatings and spots

Photograph affected leaves and the whole planting to identify the cause.

Hardiness · USDA

Species and cultivar dependent

There is no common USDA zone or minimum temperature for this group. Check individual plant hardiness and account for containers and winter wet.

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