  • Avoid spraying baking soda on the plants during hot and humid weather conditions, as it can burn leaves.
  • It’s vital to measure the correct amount of baking soda, as too much can damage the plants’ stems and leaves.
  • Avoid applying baking soda to the plants’ flowers since it can cause discoloration or damage.
  • In case there is any irritation after exposure to the baking soda solution, rinse the affected area with water.
