FAQ
What materials are these 100cm planters made from?
Our collection includes options in terracotta, resin, and ceramic. Terracotta offers a classic look and excellent breathability for plants, while resin provides durability and weather resistance, and ceramic is available in a range of decorative styles.
How heavy are the 100cm planters?
The weight varies considerably depending on the material – terracotta pots can be quite substantial (around 15-20kg), while resin and plastic options tend to be lighter, typically between 8-12kg. Check the product details for exact specifications.
What's the best way to prepare a 100cm planter for planting?
Before planting, ensure the pot has drainage holes – crucial for preventing root rot. Line the bottom with horticultural fleece or gravel to improve drainage further and add a layer of appropriate potting mix suitable for your chosen plants.
Can I use these planters indoors as well as outdoors?
Many of our resin and ceramic 100cm planters are designed to be used both indoors and out, but always consider the material’s suitability for the environment. Terracotta is best suited for outdoor use due to its breathability.
Do these pots come with any protective coatings?
Some of our ceramic and terracotta planters feature a sealant to protect against weathering. Resin pots often have UV protection to prevent fading, but always check the product description for specific details.
What size plants can I grow in a 100cm planter?
You can successfully grow a wide range of plants in these planters – from larger shrubs and perennials like Lavandula and Salvia to smaller trees depending on the pot’s material and your climate. Research the mature size of your chosen plant beforehand.
Are these planters suitable for raised beds?
While some resin and ceramic options could be used in a small raised bed setting, terracotta is generally not recommended due to its weight and potential fragility. Consider the overall dimensions carefully before placing them in a raised bed.
What potting mix should I use with these 100cm planters?
Use a good quality, well-draining potting mix specifically formulated for containers. A blend containing peat moss, perlite and compost is often suitable – always check the plant’s specific needs before adding amendments.
How do I clean my 100cm planter after use?
Clean your planter with a mild detergent and water to remove dirt and algae. Avoid using harsh chemicals that could damage the material; allow it to dry completely before replanting.
What's the typical lead time for delivery of these 100cm planters?
Delivery times vary depending on your location and the retailer’s stock levels. Check the Amazon UK listing for estimated delivery dates, which are usually provided at the time of order – standard delivery typically takes 2-5 working days.
