watering in polytunnel

[Ros]

we are only watering our polytunnel once a week at the moment – only when we have loads of mature plants like tomatoes, peppers etc do we up it to twice a week during hot weather. We find that if we water well each time then the roots go down to find the water and make better plants than if we watered more frequently and the roots do not go so deep and plants more likely to suffer if the watering ever gets missed. We make sure we water even where things are not planted at the moment and then the moisture builds in the soil.
