Tips for caring for acidophilic plants

Apart from the care mentioned above in each case, here are some tips to take care of plants for acidic soils or acidophilic plants :

  • Acidophilic plants need a special substrate for them whose pH is low, usually never above 7, since they do not grow in alkaline or high pH soils.
  • The substrate for acidophilic plants can be found easily in specialized stores. Always used to ensure that your plant has a soil with a pH between 5 and 6. These are generally made with a base of peat moss, perlite and vegetable compost.
  • By preferring pure water, we advise you to take advantage of rainy days to irrigate naturally.
  • To prevent the leaves of acidic soil plants from turning yellow, it is important that you use iron sulfate to acidify the soil . For this you only need to dissolve between 1 and 3 grams of it and dissolve it in approximately one liter of water. 1 gram dissolved in 1 liter of water.
  • We can also use citric acid to acidify the irrigation water and make sure it will help lower the pH.
  • Try not to place them in full sun if the summer is humid and in half shade if it is too hot. This will prevent the leaves from drying out.
  • Always use specific fertilizer for acidic plants. Some of the we recommend are worm castings or organic compost.
  • You can create your own homemade compost for acidophilic plants using apple cider vinegar . You only have to pour a tablespoon of vinegar for each liter of water.
