Longtime Thorvin Enthusiast


It was a profound pleasure to visit Jack Bostic and see his homestead farm. It was immediately apparent that this man has a vast amount of experience in, and knowledge of, growing and caring for plants. He uses Thorvin for Plants – Foliar and Thorvin’s kelp meal very successfully on his four acres of organic gardens and orchards. Jack was happy to share how he does it, and his sense of humor really makes you feel at home. When asked how he applied foliar spray, his reply was priceless: “I use a sprayer, of course! …any time I spray anything, I throw some seaweed into it. I use surfactant to make it stick to the leaves. I started out using natural soaps or real mild detergent, but for several years now, I’ve been using a natural surfactant made from yucca.”

Jack has over 100 apple and pear trees and estimates that he grows between 50 and 75 different varieties of apples. He’s been adding seaweed to his soil mix before planting for over 40 years. When asked how often he sprays Thorvin for Plants – Foliar, Jack says it varies depending on crop, season and if the plants are stressed or not. Typically, he sprays 2 – 3 times per season.

It was a treat to have a tour of his orchard, gardens and root cellar and a pleasure to enjoy samples of many of his crops, including more varieties of apples than you’ll find in any supermarket.
