Product Description
PLANT!T Vermiculite is a firm favourite with avid gardeners, due to its excellent water retention properties, and ability to be added to any growing media. Vermiculite is a natural, sterile, soft mica mineral with great water holding and insulation properties. It also offers a high cation exchange capacity which means it will slowly release nutrients back to your plant which it has absorbed during watering.
Vermiculite can also aid propagation when used as a top layer, as it reduces evaporation and can help ensure the seed case is lost. Using Vermiculite also reduces plant stress in extreme weather conditions due to its insulation properties.
Vermiculite is safe to handle, odourless, lightweight and easy-to-use.
Key Benefits:
- Improves air balance
- Increases water retention
- Helps to maintain an even temperature
- Holds and makes the available nutrients readily available for plants due to ‘cation exchange’ properties
Vermiculite can be used:
- Alone as a seed starting medium or mixed with compost at 50/50 rate
- For seed germination, pricking out, potting-on and plants in containers or tubs
- Used for pricking out or potting on
- In larger pots and containers to decrease the weight and improve water retention

How to Get the Most Out of Your Herb Garden
Few things lift everyday cooking quite like fresh herbs. A handful of basil torn over pasta, rosemary crackled onto roast potatoes, or parsley snipped straight into a salad can transform a meal in seconds. Yet many of us share the same frustrating experience: a lush supermarket basil plant that looks perfect on Monday and is completely dead by Friday.


Soil Types: What Works Best for Each Seed and Plant Variety
Soil is arguably the most important part of your garden. With healthy soil, you will get healthy plants, and with poor soil, your plants will struggle to thrive. The type of soil you have will determine the kind of plants you can grow in it. While a lot of plants are very adaptable, if you grow plants suited to the conditions in your garden, they will always find it easier to thrive.
