Jonathan’s Vineyard Blog - July 2025
A consequence of warm, dry Summers (such as 2025) is the prevalence in English vineyards of a disease called ‘powdery mildew’; unchecked it can devastate the entire grape crop and so vigilance is required in order to prevent it taking hold. It thrives in humid weather and especially where airflow between the vines is limited.
Powdery mildew infection appears as a white, powdery coating on leaves, stems, and fruit. If left untreated it can stunt growth, reduce fruit quality, and even affect the flavour of the wine.
Of the two varieties which we grow at Godstone the most at risk from mildew is Bacchus due to its dense canopy of foliage. Our other variety, Seyval Blanc, is fairly resistant to mildew.
The best thing to do in order to prevent mildew from taking hold is an enhanced programme of canopy management, especially leaf stripping - which significantly improves air flow around the grapes, combined with reducing the amount of foliage.
We rely upon a loyal group of friends who kindly offer their services voluntarily on several days throughout the Summer in order to help us with our canopy management and we are eternally grateful for their help.
Our vineyard will be open on three Saturdays during July and, if you would like to visit, please kindly reserve your spaces using the links below:
SATURDAY 12th JULY

We hope to see you during July!
Kind Regards
Jonathan
