  • Tidbit
  • Always test your soil to find out if it is alkaline, neutral or acid using a soil kit from a Garden Centre before buying plants. You will save yourself a lot of money in the long run. Otherwise plants may die or struggle to survive or you will have to buy a lot of compost to create special beds.
