Sustainable Farming with Cover Crops

Cover Crop in the Vineyard 

While the vines are dormant and quiet for the Winter, a tractor bust les down the rows showing that there is still work in the vineyard. To start the year off right at Parrish Family Vineyard, we focus on sustainable vineyard practices such as cover crops. 

What is a cover crop? 

Cover crop is vegetation that is planted between the vineyard rows to benefit the soil as well as provide other positive improvements to the growing season for the year. Generally a blend of grasses, legumes, and brassicas are selected. The cover crop seed is spread by tractor, but cover crops can even be utilized by personal gardners to protect soil in raised beds over the Winter. 

What are the benefits of utilizing a cover crop?  

Improve Soil Health: The cover crop improves the soil structure and increases water permeation during the important months of rain. Furthermore, it helps maintain organic matter and add nitrogen to the soil, while the vines are at rest. It is a way to prepare for the growing season ahead. Once we mow the cover crop, the soil is ready for the vines to go through budbreak. 

Increase Beneficial Insects: When you plant cover crops, it welcomes beneficial insects that will protect vines from things like mites. 

Assist in Weed and Erosion Control: Cover crops can help decrease the growth of weeds in between rows which leads to herbicides not being used. The cover crop helps protect the soil from eroding. With the storms, rains can wash away the important topsoil, but cover crops reduce this activity. 

The 2026 Cover Crop 

Currently, we have a cover crop that has sprouted from last year’s sowing as we allow our cover crops to go to seed for regeneration. After a wonderful amount of rain during the holidays and the first few days of January, the soil was left with moisture for the seeds. Since it is Winter, we selected a cold tolerant seed mix of plants such as brown flax, nitro radish, rapeseed, barley, black oats, forage pea, lentil, faba beans, sweet clover, and spineless safflower. Our Vineyard Assistant, Mason, then took a drill with a seed cup, disk opener, hopper, and press wheel down the rows of the vineyard with a tractor to distribute the seeds. By Spring, we will have more cover crop sprouting and aiding in soil health as well as pest management. This annual process is necessary for sustainable farming success and we are so thankful to be applying this practice to our vineyard in Paso Robles.
