My Backyard Vineyard: Season 3: Episode 4: Bloom & Petiole Analysis

Bloom to fruit set is a critical time for grapevines. Many things can affect pollination and fruit formation: the weather, irrigation, disease and the mineral nutrition. In this video I describe bloom, the development of the clusters through fruit set, and the mineral nutrition of my grapevines at this time in my backyard using petiole analysis.

Very interesting to hear about the deficiencies that you are facing. I am growing my vines in ground that was transported here. An analysis was done in the neighbourhood and we had excess of Boron, Arsenium and heavy metals. I stopped with fertilization last year as I got too much Nitrogen. It is stabilizing now. I had lots of aphids last year and much less this year. Also less inflorescences, but I rather have the present situation. Less aphids but also less fruits. Our winter and spring are extremely wet with record rainfall and I check regularly on signs of fungal decease and bugs. Birds are my greatest friends. Your videos are very informative and help me to make right decisions.

@@grantcramer I have been battling weird nutrient issues that are like chasing gremlins you fix one then another crops up that looks like another and I keep trying various nutrients because im a professional winemaker and know a bit about viticulture not as much as someone who grows grapes 100% for a living but its been frustrating fixing one to find out another pops up or having 2 that look identical and trying to figure out whats causing it.

Yes, it takes time to get a handle on it. Be patient and keep working at it. I am sure you can resolve the issue eventually. Soil is really just a physical structure to house the nutrients, you can eventually replenish it with proper nutrition. Hydroponics proves that!
