Specialty cut flowers are one of the most profitable field crops you can grow. Lynn Byczynski, editor of Growing For Market newsletter (see Resources section), estimates a value of $25,000 to $35,000 per acre for field-grown cuts. The most basic requirements are at least half an acre of open, arable land, a rototiller, and, of course, time and effort. This publication is directed to those new to market gardening, but commercial vegetable growers, tobacco farmers, and young people interested in summer income are all potential candidates. Even grain and livestock farmers have increased profitability in their operations by adding cut flower production. For many greenhouse and nursery operations, mid-summer business is slower, relative to spring. A field-grown cut flower business is a viable option to fill in the summer production and cash flow gap.

Background: Hops were grown in Virginia even in the days of Thomas Jefferson, but production eventually shifted away from the east coast in favor of the Pacific Northwest. For the past few decades, hops have not been grown commercially on a substantial level in Virginia. However, beginning several years ago when the craft brewing industry surged, renewed interest in hops production led to a rapid increase in the number of hobby and commercial hops growers. A fall 2014 survey showed approximately 50 growers in the state, but as of 2015 many new growers have been added to the ranks. Much of the production is clustered in Northern Virginia and the I-81 and I-64 corridors, but growers can be found in all regions of the state stretching from Southeast to Southwest Virginia.

Food safety is a hot topic for hop growers and brewers. With multiple acronyms for various practices, standards, and regulations: GAPs, FSMA, PSR, PCR, and more; the confusion is understandable. Let’s examine where the small-acreage hop grower fits in. This fact sheet serves as an orientation to these standards,regulations, and practices as they may apply to hops; it is in no way a complete set of guidelines or substitute for training.

Have you ever wondered if it is possible to enjoy the beauty of bulbs in the middle of winter? The answer is definitely yes! Many people are familiar with the hourglass-shaped vase filled with water and topped with a hyacinth bulb, or a low bowl filled with several Paper White narcissus, and the popular boxed amaryllis bulb as a welcome winter holiday gift. Most bulbs can be forced but additional planning is required in order to have a successful period of blooms.

According to the 2017 Census of Agriculture, U.S. greenhouse vegetable farms more than doubled from 2012 (USDA 2019). Virginia fell within the top 10 states for acreage of vegetables and berry crops grown under protected culture. Protected culture includes greenhouses and structures like high tunnels. With close to two and a half million square feet devoted mostly to tomatoes, vegetables, herbs, and strawberries, the value of Virginia greenhouse sales in 2017 was over 31 million dollars! A lot of this increase in square footage was due to the addition of large operations coming into Virginia.

With the increasing number of controlled environment agriculture farms, Virginia Cooperative Extension is working closely with specialty crop growers to address the challenges of establishing and managing hydroponic greenhouse operations. Growers interested in producing food crops in controlled environments can use several different types of hydroponic systems. One of the most common types of hydroponic systems is called nutrient film technique (NFT).

One common type of hydroponic system is known as a media system and utilizes some type of containerized media to grow plants. This media or substrate is used primarily to anchor the plants while nutrient solution is delivered to the plants via sub-irrigation or top-irrigation. The terms media and substrate will be used interchangeably in this publication.

This factsheet is part of a series of seven factsheets targeting beginning farmers growing edible crops using hydroponic greenhouse systems. There are also five videos that are related to the factsheets and included in the numbering sequence.
