Overwintering - How to make your planters weatherproof.

Planters are not automatically winter-proof and frost-proof. So if you want to avoid taking your heavy planters into the warm before each winter so that they are not damaged, you should make sure to choose high-quality containers when buying.

But what does winter festival actually mean?

An outdoor bucket should withstand the following weather stress:

  • Thermal influences

    Your planter must withstand heat, cold, frost and changes in temperature without cracking. Sun exposure must not cause any damage to the material.

  • humidity
    An outdoor planter needs to be waterproof. If the material absorbs water, it can freeze to ice and cracks appear in the bucket.

  • Mechanical load
    Wind stability is often used here. Since the wind not only hits the surface, but also exerts force on the whole bucket, the bucket should be stable and not fall over. However, since most planters are usually fully planted, this aspect does not play a major role.

  • Photochemical influences
    UV rays from the sun can break down organic compounds and destroy molecules. Therefore you should make sure that the outdoor tub is UV-resistant.

Buckets made of the material are particularly suitable here Fiberstone which consists of a combination of artificial fibers (glass fiber fabric mats) and natural rock flour. Thanks to the high stability of Fiberstone, frost and other weather conditions do not damage the material. Sustainability starts with the use of durable materials.

Packing outdoor tubs winterproof:

Why do I have to pack my bucket when the plants are winterproof? Every plant, no matter how hardy in our latitudes, needs water in winter too. Buckets that are not protected from frost would freeze permanently in the event of prolonged frost and the plant could not absorb water. The plants do not freeze to death, but rather they dry up. External factors such as wind and sun intensify this effect.

To make your outdoor planter winter-proof, you should pay attention to the following points:

  • Location: If possible, place your planter in a sheltered, shady location. It is best to place it close to a house wall so that the planter and the plants are less exposed to the weather.
  • Protective mats: Wrapping the planter with protective mats made of sheep's wool, jute felt or bubble wrap are good options and protect against the cold.
  • Hoods: Frost protection hoods also completely enclose higher plants and thus ensure optimal protection in winter
  • Cold from below: Wooden panels or polystyrene panels are suitable to prevent the roots from freezing.

tip: Before you pack your planters for winter protection, check the drainage holes in the bottom of the tub. If these have overgrown over the summer, simply cut off the protruding roots and drill the holes. No fear! - The plant does not mind that a few roots are damaged. A functioning drain is essential for wintering. We recommend our pot feet for this, with which the drainage of excess water is guaranteed.

Which types of plants are actually winter-proof?

Planting outdoor planters beautifies every garden, terrace and front door. So that the complex planting does not have to be renewed every year, hardy plants that survive the winter without any problems are suitable here. We introduce you to our top 10 winter container plants.

  • Lavender (Lavandula angustifolia)
    The evergreen lavender captivates in spring with its nectar-rich, wonderfully fragrant, violet flowers. It is robust and easy to care for.
