When should planters be put out?
As a rule, planters are frost-resistant. Your planters could therefore remain outside even in winter. Unfortunately, this does not apply to all potted plants.
If you have stored your potted plants in their winter quarters, you should put them out in early spring. However, this assumes that temperatures are above freezing and frost is no longer to be expected.
Which materials are suitable for outdoor planters?
An increasingly popular material for outdoor planters is a fibreglass material mix. Teak wood is also very popular, as the warm brown tone sets homely accents.
Modern planters with a concrete look are also particularly stylish. These are made of glass-fibre reinforced natural cement.
Polystone is also frequently used as a material. This is a synthetic stone based on stone powder and synthetic resin.
Plastic - sometimes glass-fibre reinforced - is also ideal for outdoor planters. Plant pots made of polypropylene are also unbreakable and resistant to frost and weathering.
Different materials for outdoor planters
Outdoor planters are also available in a mix of materials. The combination of teak and stainless steel is very popular. The stainless steel forms a successful, elegant contrast to the teak.
Not visually visible is the combination of glass fibre composite material as a base and a high-quality gelcoat coating. This technique is known from shipbuilding. Planters made of this material are impermeable to water even after years.
Which planters are frost-proof?
Most materials are frost-resistant nowadays. This applies, for example, to planters made of concrete, stainless steel, polyrattan and teak. Even planters made of fibreglass are weatherproof and frost-resistant - as long as the material does not contain any stone admixtures.
