Air flow and the benefits of aeration on tomato plant leaves
We could all do with a gentle breeze when the weather is hot! However, tomato plants need plenty of air movement to help keep them from disease and to help them absorb the nutrients they need.
Here are a few of the benefits:
- Good airflow reduces condensation and the risk of fungal disease both in the greenhouse and outside.
- Leaves also dry more quickly in a gentle breeze.
- Plants perspire (transpire) a bit like humans but through their leaves. This enables them to replace moisture and nutrients through their roots.
- Good aeration encourages evaporation of moisture through leaves, and therefore, increases moisture and nutrient uptake.
- Slight movement caused by good airflow encourages strong stems.
When Sowing Too Early
One of the big problems with sowing too early is that plants become leggy and have stems that are too thin. A gentle breeze created by a fan, if growing indoors or in a greenhouse, helps to prevent leggy seedlings.
Disease and Insect Attack
Also, if plants are too close together or have lots of wet decaying leaves around their base, the lack of airflow will leave them exposed to fungal attack and it’s a good place for insects to gather and lay their eggs.
Remove decaying and yellow leaves from around the base of both tall and bush varieties to allow the air to circulate
Helps Absorb Carbon Dioxide
Tomato leaves need to absorb carbon dioxide from the air around them. Without a good airflow, their intake of carbon dioxide is reduced and plants will grow more slowly.
So, get the air circulating, keep your plants healthy and watch them grow!
