Elder is very undemanding and grows almost anywhere. Ensure sufficient space as it grows large quickly. Raw berries are mildly toxic and should only be consumed cooked. Flowers and ripe berries are edible and versatile.

Pruning

Sambucus Pruning

renewal_pruning

Goal

renewal_pruning

Pruning timing

late_winter

FebMar

Basic pruning for shaping and rejuvenation, removal of old shoots. Before bud break, once the harshest frosts have passed.

summer

JunJul

Thinning and removal of excess growth, promoting air circulation. After flowering or after harvesting flowers, to avoid impacting berry formation.

Remove

  • Dead, diseased, or damaged branches
  • Inward-growing shoots
  • Competing shoots
  • Branches hanging too low

Preserve

  • Strong, well-positioned main branches
  • Young, fruit-bearing shoots

Avoid

  • Cutting back all shoots too severely at once, as this can reduce fruiting in the following year.
  • Pruning during frost.

Tools and hygiene

Clean and disinfect pruning tools before and after use, especially after cutting diseased branches, to prevent disease spread.

Health

Pests, Diseases

Pests

Aphids

Small, sap-sucking insects that colonize young shoots and leaves, weakening the plant. They can cause yellowed, deformed leaves and stunted growth.

Elder aphid

A specific aphid species that infests elder, causing shoot distortion and honeydew.

Spider mites

Small arachnids that appear in dry weather, leaving fine webbing on leaves. They suck plant sap and cause yellowish stippling.

Diseases

Elder rust

A fungal infection characterized by yellow-orange pustules on the underside of leaves and yellow spots on the upper surface. Can lead to premature leaf drop.

Powdery mildew

A fungal disease appearing as a white, powdery coating on leaves, stems, and flowers. Reduces photosynthesis and can lead to growth disorders.

Verticillium wilt

A soil-borne fungal disease that clogs the plant's vascular system. Leads to wilting shoots and leaf loss, often one-sided on the shrub.

Deficiencies

Iron deficiency

Causes chlorosis (yellowing) of young leaves, while the veins remain green. Often occurs on alkaline soils.

Magnesium deficiency

Leads to a characteristic interveinal chlorosis (yellowing between veins), usually starting on older leaves.

Plant health

FAQ

Are elderberries poisonous?

Raw elderberries contain sambunigrin and can cause gastrointestinal upset. They are safe and edible after cooking. Leaves, stems, and roots are toxic.

When is the best time to plant elder?

The best time to plant elder is in spring (March-April) or autumn (September-October), when the soil is moist but not frozen.

How do I prune elder correctly?

Elder benefits from annual renewal pruning in late winter (February-March), where about one-third of the oldest shoots are removed near the ground. This promotes new growth and fruiting.

Can elder grow in a container?

Due to its size and rapid growth, elder is not well-suited for container growing. It requires ample space for its roots and spreading canopy.

  5. Hygiene: disinfect pruning tools and remove and dispose of infected plant parts.
Monitoring
  1. Regular visual inspection of leaves, shoots, and flowers for signs of pests or diseases.
  2. Pay special attention to young shoots and leaf undersides.
  3. Check soil moisture.
Organic first response
  1. For aphids: water jet, beneficial insects, rapeseed oil, or soapy water.
  2. For spider mites: increase humidity, use a water jet, and introduce beneficial insects (predatory mites).
  3. For powdery mildew: baking soda or milk spray, plant-strengthening agents.
  4. For rust: remove infected leaves and ensure good ventilation.
Notes

Prevention is key to keeping elder healthy. A healthy, well-maintained shrub is more resistant to pests and diseases.

Diagnosis

Diagnosing problems with elder relies on careful observation of symptoms such as discoloration, wilting, leaf deformation, presence of pests, or fungal infections. The timing of occurrence and the affected plant parts are important indicators. In case of suspected fungal diseases like Verticillium wilt, accurate identification is crucial as they are difficult to control and often require plant removal.

Phenology
Stages
  1. Leaf-out: Spring (March-April)
  2. Flowering: Late spring to early summer (May-June)
  3. Fruit ripening: Late summer to autumn (August-October)
Notes

The exact timing of leaf-out, flowering, and fruit ripening can vary depending on the cultivar and site conditions.

Harvest
  1. Flowers: June-July
  2. Berries: August-October
Harvest details
Harvest frequency

Annually, as soon as flowers or berries are ripe.

Harvest indicators
  1. Flowers: Fully open, fragrant, harvested on a dry morning.
  2. Berries: Deeply colored (depending on variety), easily detach from the cluster.
Post harvest handling

Process or dry flowers immediately. Handle berries carefully as they are delicate. Store chilled or process.

Storage
  1. Fresh flowers: Short-term refrigerated (1-2 days)
  2. Dried flowers: Cool, dry, dark (several months)
  3. Fresh berries: Short-term refrigerated (1-3 days)
  4. Processed products (juice, jelly, etc.): According to processing instructions
Storage details
General storage category

Cool, dry, dark for dried goods; process fresh or refrigerate.

Storage life

Dried flowers: up to 1 year. Processed products: depending on type (e.g., syrup several months, jam up to 2 years).

Processing options
  1. Flowers: Tea, syrup, liqueur, fritters.
  2. Berries: Juice, syrup, jelly, jam, wine, liqueur, pie filling.
Kitchen usage

Elderflowers and elderberries are versatile in the kitchen. Flowers are used for syrup, jelly, liqueurs, and fritters. Berries are suitable for juices, jams, jellies, wines, and as pie fillings. Important: Only use cooked berries!

Safety and edibility
Edible parts
  1. Flowers
  2. Ripe berries (cooked)
Inedible or caution parts
  1. Raw berries (mildly toxic)
  2. Leaves
  3. Stems
  4. Roots
Toxicity notes

Raw elderberries contain sambunigrin, which can cause gastrointestinal upset. They are safe after cooking. Leaves, stems, and roots are toxic.

Raw consumption

Not recommended for raw berries. Flowers can be used raw in drinks or desserts, but are more commonly cooked or dried.

Seed saving

Seeds can be obtained from ripe berries. Seeds are small and require careful separation from the pulp. Germination is often irregular and requires stratification.

Seed saving advanced

For propagation, cuttings or young plants are usually preferred, as seed germination can be slow and unreliable. If seeds are used, cold stratification for several months is necessary to break dormancy. Cultivar characteristics are not guaranteed with seed propagation.

Notes

Elder is typically cultivated as a shrub or small tree and does not require a specific rootstock. Shaping is achieved through pruning.

Ecology
Pollinator valuehigh
Wildlife valuehigh
Biodiversity notes

Elder is an important food source for insects (bees, hoverflies) and birds (berries). It provides habitat and shelter for various animal species. Its flowers are a vital nectar source.

Practical notes

Elder is very undemanding and grows almost anywhere. Ensure sufficient space as it grows large quickly. Raw berries are mildly toxic and should only be consumed cooked. Flowers and ripe berries are edible and versatile.

Seasonal content
Spring

In spring, elder sprouts vigorously. This is the best time for planting and pruning for shaping and rejuvenation. An application of compost supports growth.

Summer

In early summer, elder flowers and attracts insects. The flowers can be harvested for syrup or tea. The berries begin to develop.

Autumn

In late summer and autumn, the berries ripen. They can be harvested and processed into juices, jellies, or wines. Birds appreciate the fruits as a food source.

Winter

In late winter, it is the ideal time for renewal pruning. The shrub is now leafless, and the cut surfaces are clearly visible.
