Providing your garden with good air flow is just as important as sunshine and water. Being outdoors generally means better airflow than indoors, but problems can arise in either scenario.
When air flow is limited, the garden can remain moist and damp for extended periods of time, leading to prime conditions for fungal diseases like powdery mildew and damp soil for slugs and fungus gnats to make a new home in.
Having good air flow helps to minimize damage from insects as well as stimulate the plants to grow strong and robust stalks and limbs. Keep a close eye if your garden is at the bottom of a hill or valley or sheltered behind tall buildings or fences.
Indoors, we suggest running a fan in the room either directly on the plants or indirectly to ensure good air circulation in the room.
