Essential Gardening Equipment
Soil pH Testing
You need to make sure that you accurately test your soil to give your plants the best chance.
We use and recommend this 4 in 1 hygrometer to measure soil moisture, pH levels, nutrients, and light conditions at the same time.
Seeds
Here’s a list of more than 150 seeds that are customer favorites for Zone 9.
Germination
The best way to germinate your seeds so that they have a great start is with a germination kit. Seeds that are grown this way produce greater results.
Spade
A trusted spade is a gardener’s best friend, it helps you do the work. A long-handled spade is the most effective type.
Gardening Tool Set
For the finer work in the garden, we need those handy tools to help us cultivate. One that you can carry around in the garden is best.
Greenhouse
Every advanced gardener has a greenhouse and with so many benefits how can we do without. The acceleration and growth rate when using a greenhouse is worth the cost.
