Saving Seed
The document provides an overview of seed saving, focusing on tomatoes, summer squash, and beans. It discusses the importance of seed saving for local adaptation, genetic diversity preservation, and income generation. The key aspects of seed saving covered are seed purity, isolation techniques, plant reproductive biology, and post-harvest processing and storage methods. Proper identification of plant varieties and following best practices for parent plant selection and seed cleaning, drying, and storage are emphasized.
Spring Summer Production
Production of spring and summer crops begins in mid-December with seeding flats using seeds, growing media, and flats in a heated greenhouse with germination mats. Cherry tomatoes are set on May 2nd with other tomatoes and crops like bell peppers, cucumbers, zucchini, and mesclun growing in high tunnels. The main crops for spring and summer are tomatoes, peppers, cucumbers, summer squash, and mesclun.
Mesclun
Our mesclun beds are 42 inches wide with four rows of drip tape laid 10.5 inches apart. We densely seed different lettuce, kale, tatsoi, mizuna and arugula varieties to add color, texture and taste to our mesclun mix. For a 90 foot bed we would plant about 70 feet of lettuce and smaller sections of other greens. A common mesclun "recipe" includes several lettuce varieties that cost around $11.90 to seed a 45 foot bed. We can expect to harvest over 18 pounds the first cutting, worth at least $144.
Marketing
The document is an email from a farm providing an order form and details for their produce delivery service. It lists the various vegetables available for order such as mesclun mix, spinach, arugula, swiss chard, kale and includes pricing. A recipe for swiss chard is also provided. The email reminds customers of order deadlines, delivery windows and fees.
Ssawg High Tunnel Manage For Max
Managing a high tunnel for maximum crop production is challenging as it requires utilizing all available space, rotating crops in and out while being aware of each crop's specific timing and placement needs. The document provides advice on high tunnel crop management throughout the late winter and spring seasons to maximize production from multiple crops over multiple seasons and across multiple high tunnels.
Challenges To High Tunnel Growing
Challenges to growing in high tunnels include weeds, pests, and diseases. Weeds can be removed by hand when small but can overtake the space if unchecked. Common pests include hornworms, which can be eaten by predatory wasps. The disease Sclerotinia sclerotiorum affects crops. Strategies to deal with these challenges include using biological controls like Coniothirium Minitans, biofumigation using mustard seed meal, and solarization to heat the soil through the use of clear plastic sheeting to kill pathogens.
High Tunnel Intro
This document discusses using high tunnels for growing produce year-round at Au Naturel Farm. It describes the structure and materials used for high tunnels, and shows how the farmers are able to grow and harvest lettuce in the winter months when outside temperatures are near freezing. Photos also illustrate the growth of tomatoes, peppers, cucumbers, zucchini and other crops throughout the spring and summer months inside the high tunnels, extending the growing season compared to open field production.
Fall And Winter Production
This document summarizes the fall/winter production schedule for a Kentucky farm. It involves planning in June by buying seeds and seeding crops in flats. In August, beds are prepared and crops are transplanted and seeded with lots of irrigation. In September, mesclun and spinach are seeded and most brassicas are transplanted. Harvesting begins in November. The farm grows various lettuce varieties, kale, pac choy, tat soi, Chinese cabbage, turnips, radishes, Swiss chard, arugula, braising mix, spicy baby greens, onions, carrots, cucumbers, and summer squash during the fall and winter months.
