Mustard in the Vineyards
Mustard Plants
It must be Spring! Just look at the bright yellow fields full of mustard blooms in the vineyard. While the weather may still seem winter-like, Mother Nature is telling us otherwise.
The Andis Vineyards have never looked so beautiful with the ground cover throughout. As mentioned in my previous blog, ground cover or cover crops can be beneficial in replacing nutrients. But what about mustard plants? While mustard plants do not return vine nutrients back to the soil, they do provide biofumigation, which suppresses various soil pathogens.
Typically mustard plants are used in vineyards to suppress nematodes, a microscopic worm that infects vine roots. Nematode infection will ultimately lead to low grape production and severe vine damage. Mustard plants produce a biofumigant called glucosinolate that deters damaging nematodes.
Later in Spring, the cover crops are turned giving beneficial mulch to the soils.
So come visit us at Andis Wines and enjoy the beautiful view of our yellow vineyards while you can!
