Frequently Asked Questions

What fertilisers do you stock?

We stock a range of liquid and granular fertilisers including Seasol, Nitrosol, lawn food, orchid food, and general-purpose plant food suitable for vegetables, flowers, natives, and lawns.

What is the difference between Seasol and a standard fertiliser?

Seasol is a seaweed-based soil conditioner and plant tonic that improves root development, soil health, and plant resilience — it is not a fertiliser. Standard fertilisers like Nitrosol provide nitrogen, phosphorus, and potassium to directly feed and promote plant growth. Both can be used together for best results.

Do you stock potting mix for specific plant types?

Yes. We stock premium potting mixes formulated for general use, indoor plants, native plants, vegetables, and orchids. Using the right potting mix for your plant type improves drainage, aeration, and nutrient availability.

How do I test my soil pH?

We stock soil pH test kits that allow you to test your garden soil at home. Most vegetables and flowers prefer a slightly acidic to neutral pH (6.0–7.0). If your soil is too acidic or alkaline, you can adjust it with lime (to raise pH) or sulphur (to lower pH).

What plant ties and supports do you stock?

We stock bamboo stakes in a range of heights, soft plant ties, flex ties, jute twine, and plant clips for training and supporting seedlings, climbing plants, tomatoes, and other vegetables without damaging stems.

They have a good selection of incandescent light bulbs. They are getting harder to find and they helped me pick a good type. The incandescent bulbs are much healthier. I saw it on hubermans channel.
