Product Information
Full details
Deco-Pak Chelsea Horticulture Alpine Grit is an essential soil amendment ideal for gardeners focused on cultivating alpine plants, rockeries, and container-grown specimens. Its primary benefit lies in its ability to significantly improve drainage and soil stability, preventing root rot and waterlogging in sensitive species. However, users should be aware that because it is a mineral-based product, it can slightly alter the pH balance of the surrounding soil, so it is best used in moderation for plants that prefer neutral to alkaline conditions.

FAQs
Can I use this for cacti and succulents?
Yes, it is excellent for cacti and succulents as they require sharp, free-draining soil.
Does this grit affect soil pH?
Being a mineral grit, it may slightly raise the pH, so it is best avoided for plants that require very acidic conditions.
How much grit should I mix into my potting compost?
A standard ratio for alpine plants is 1 part grit to 3 parts compost, though this can be adjusted based on the plant's specific needs.
Is this product reusable?
Yes, you can sift the grit out of old compost, wash it, and reuse it for new potting projects.
Can I use this for aquarium setups?
No, this is a horticultural product and may contain minerals or dust not suitable for aquarium ecosystems.
Troubleshooting
Water pooling on the surface of the pot
The drainage holes at the bottom of the container may be blocked; lift the pot and clear any debris.
Plant showing signs of nutrient deficiency
Grit improves drainage which can wash out nutrients faster; consider adding a slow-release fertilizer to your mix.

Setup, Compatibility & Care
Before adding the grit, ensure it is rinsed with water to remove any fine dust particles that could potentially clog drainage holes. For compatibility, it works seamlessly with standard potting composts and loam-based mixes. While the grit is inert and requires no special maintenance, you should check your containers annually to ensure the grit has not sunk into the compost, which may necessitate a fresh top-up layer. When working with the grit, always wear gardening gloves to avoid minor skin abrasions due to its abrasive, mineral surface.
