  • the substrate surface should always be allowed to dry out
  • if fertilized weekly from May to September, the strong herb is satisfied

With regard to the dosage of watering water among amateur gardeners often uncertainty. If yellow leaves appear, put the pot in 5 centimeters of water. Due to the capillary action, the basil will draw the required amount into the root ball. If the thumb test reveals a slightly moist soil surface, watering is complete. If you administer only organic fertilizer, overdosing is excluded in this point.
