Caring for Your Polystone Decorative Pots & Planters
Polystone decorative pots and planters are designed to provide years of reliable outdoor use. With a little routine care, they'll continue to look their best season after season.
Whether you've chosen black, white or grey planters, this guide explains how to clean, maintain and protect your pots to keep them looking their best.
Polystone Care Guide
Cleaning Your Polystone Planters
Clean your planters regularly using warm water, a soft cloth or sponge and a mild detergent.
Remove dirt, dust and algae as required, avoiding abrasive cleaners or wire brushes that could damage the finish.
Caring for Black Polystone Pots
Black polystone planters naturally absorb more sunlight than lighter colours. Over time, exposure to UV rays and the elements can cause the surface to appear lighter or chalky.
To obtain a rich and deep black finish, the manufacturer recommends to on delivery applying a suitable matt stone sealer or light mineral oil designed for outdoor decorative stone surfaces.
White & Grey Polystone Pots
White and light grey polystone planters generally require less colour maintenance and will retain their appearance with routine cleaning.
Use of a mineral stone oil once a year is more then adequate to retain the planters surface lustre.
Simply wash occasionally with warm soapy water to remove dirt and algae.
Planter Planting Guide
To ensure your planter looks its best and your plants thrive, we recommend following these professional planting steps:
- Foundation: Place the planter on a firm, level surface; use stone pot feet for improved airflow.
- Drainage: Keep drainage holes clear for outdoor use; ensure the plug is secure for indoor use.
- Base: Add a 1/4 layer of hydroclay pebbles or broken crock for water management.
- Soil: Use free-draining potting soil mixed with perlite or vermiculite to prevent compaction.
- Planting: Firm the root ball into the soil to ensure roots establish effectively.
- Finishing: Apply a top layer of potting bark or decorative stones to retain moisture and suppress weeds.
Important Warranty Notice:
Please follow these guidelines carefully. Failure to adhere to the manufacturer's recommended planting and maintenance advice may void your product warranty.
Polystone Planter Repair & Maintenance Guide
While polystone is highly durable, minor surface scuff damage can often be repaired by following these steps:
- Sanding: Using a light 120–240 grit sandpaper, gently polish out the damaged area using long, even strokes.
- Clean: Wipe the area clean with a microfibre cloth to remove all dust and residue.
- Seal/Blend: Apply a stone sealer or mineral oil to the full surface of the planter. This helps the repaired area blend seamlessly with the rest of the finish.
Please Note:
Repair results can vary depending on the depth and nature of the damage. Additionally, please be aware that colour plays a role in the finish: repairs on Charcoal Black planters may remain more visible than on Light Grey and White finishes. While the appearance of the mark will be significantly reduced, the material's interaction with natural light may mean some signs of the repair remain visible on darker-coloured surfaces.
Frequently Asked Questions
Discover expert advice on cleaning, maintaining and protecting your polystone decorative pots and planters, including winter care, colour restoration and long-term maintenance.
Why has my black polystone pot turned lighter?
This is a natural result of prolonged exposure to sunlight and weather. Applying a suitable stone sealer or light mineral oil will help restore the deeper black appearance.
Can I leave my polystone planter outside all year?
Yes. Polystone planters are suitable for year-round outdoor use, provided good drainage is maintained and water is not allowed to freeze inside the planter.
How often should I apply a sealer or oil?
This depends on exposure to sunlight and weather conditions. For black planters in full sun, checking the finish once or twice a year is generally sufficient.
What products should I avoid?
Avoid abrasive cleaning pads, bleach, strong solvents and pressure washers, as these may damage the surface finish.
