Overwintering: simple protection, big impact
Most winter losses can be prevented with good timing and simple protection. Here we show you when to cover (trigger points), how thick the soil mound around the base should be, how to handle overwintering in pots, and when and how to remove the protection in spring. You’ll also get guidance on winter watering and typical mistakes. Is your rose planted out in the ground, or do you overwinter it in a container – and which risk is greater for you: frost, wind or drying out?

Quick principles
- Covering: in open ground a 10–15 cm soil mound around the base (in exposed, windy sites 20–25 cm).
- Material: compost, fine bark, dry leaves – leave 3–5 cm of clear space around the stem.
- In pots: frost-free, bright place or insulated container; only moderate watering.
- Timing: just before a period of persistent night frosts; in mild spells don’t cover too early.
- Spring: remove protection gradually, watching for the risk of late frosts.
Own-root plants – good ability to regenerate; heavy pruning in autumn should be avoided.

Timing & trigger points
- Start: when several consecutive nights of frost are forecast (≈ −2…−5 °C) and the soil surface is frozen.
- Not too early: if it’s too warm under the cover, the base can become airless and shoots may start too soon.
- Urban microclimate: in inner courtyards you can cover later; on exposed edges and corners, cover earlier.

Preparation (step by step)
1 Hygiene: remove diseased leaves around the base; disinfect tools.
2 Soil moisture: before frost, water moderately (don’t let water stand around the plant).
3 Material for mounding up: compost/bark, dry leaves; leave a free ring 3–5 cm wide around the stem.
4 Securing climbers: loosely tie in and secure long canes so the wind can’t whip them around.

Private garden
- Covering: 10–15 cm; in exposed, windy sites 20–25 cm.
- Ventilation: plastic sheeting should not touch the stems directly; avoid stagnant, humid air.
- Snow load: after heavy snowfall gently shake off the snow so branches don’t snap.
Positioning: Private garden • Spring pruning: Pruning.
Jump to pots/terrace →
Pots / terrace
- Place: sheltered, frost-free (−2…+5 °C), bright space; if the pot stays outside, insulate the container (jute, insulation material, decorative cladding).
- Raising the pot: lift the container onto pot feet or a grid so excess water can drain away.
- Watering: a little water every 4–6 weeks; the compost should not dry out completely, but there must be no standing water.

Public and green spaces
- Mulch: 6–10 cm long-lasting mulch; tidy edges, information pictograms.
- Salt and trampling stress: keep planting 60–100 cm away from road edges; after salting, flush with water if the weather allows.
- Protection: concealed drip lines, protective edging; regular checks for vandalism.

Winter watering
- Open ground: in frost-free periods, water moderately every 4–6 weeks if the soil is dry and conditions are windy and with little rainfall.
- Pots: a little water every 4–6 weeks; don’t leave water standing in the saucer.
- Timing: at +3…+8 °C in a frost-free window; don’t wet the foliage.

Removing protection in spring
- Gradually: first remove only the top layer of the cover; remove it completely only once hard frosts are over.
- Watch for frost damage: if cold nights are forecast, protect young shoots again temporarily.
- First steps: deep watering, then, depending on the weather, early spring pruning.
After this you can move on to starting feeding and preventive plant protection.
Jump to mistakes →
Common mistakes
- Covering too early and too thickly → airless conditions, early shooting.
- Plastic foil directly on the stems → rot, bark damage.
- Standing water around the base / in the saucer → roots suffocating.
- Removing all protection suddenly in early spring → frost damage to new growth.
Troubleshooting: improve ventilation, remove protection gradually, check soil moisture.

FAQ
When should I put the cover on?
Just before a period of persistent night frosts; in mild, wet weather wait to avoid stagnant, humid conditions.
Can I use only leaves for covering?
Yes, if they are dry; mixed with compost/bark the cover is more stable and less likely to slip.
Should I overwinter potted roses indoors or outdoors?
The safest option is a frost-free, bright place; outdoors only in an insulated pot, in a sheltered corner, with moderate watering.
