Essential Gardening Equipment
Soil pH Testing
You need to make sure that you accurately test your soil to give your plants the best chance. This Apera kit has ±0.1 pH accuracy, see the star ratings over at Amazon.
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. Check the specs of the MXIC over at Amazon.
A trusted spade is a gardener’s best friend, it helps you do the work. A long-handled spade is the most effective type and this DeWit with a lifetime guarantee is our favorite – see the quality at Amazon.
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 and we like this well-designed set with super reviews at Amazon.
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. The Exaco 116 square foot with safety glass is ideal at Amazon. On a budget see the poly tunnel at Amazon.
One of the issues people have is that their crops produce all at once. The best way to overcome this is with a dehydrator so you can store your food for years and the flavor is amazing. The best one on the market is the Excalibur with a 10-year guarantee, see it at Amazon.
