How We Trial & Select Varieties for Growing in Greenhouses, Hoophouses & High Tunnels
Greenhouses and tunnels of every imaginable type are cropping up everywhere, as growers around the globe discover the many advantages of protected culture: season extension, better yield and quality, protection from adverse weather and pathogens, and more.
Growing within a protected environment does carry its own set of challenges, though â including limited space, more intensive plant maintenance, and increased risk of diseases specific to greenhouse conditions, such as leaf mold. Crops need to perform particularly well to deserve placement in the valuable real estate of a greenhouse or hoophouse.
The research team at Johnny's Selected Seeds is committed to breeding, trialing, and selecting crops well-suited to the greenhouse environment. In the process we've learned a lot about how to identify the top performers, and what distinguishes them from varieties best grown in the field. Here are some findings from our greenhouse breeding and trialing team, so you know what to look for, along with some recommendations for varieties we think will perform well in your greenhousesâ¦

[Disease Resistance, Habit & Recommendations]
While it's possible to grow virtually any tomato with success in a high tunnel, some perform better than others â primarily because of their particular disease resistances, but also their habit.
Here are the top 15 from our field line-up, along with a select few from our greenhouse performers, to help you choose varieties that yield well, taste great, and bear up well under the conditions and disease pressures common in hoophouses and tunnels.
We'll start with a quick overview of disease resistances you'll want to look for in this type of tomato culture...

[Hanging String Trellising]
[Trellising & Crop Support Systems]
[Advantages, Main Types & How to Set Up]
The advantages of trellising make it a popular technique for use with many vining and heavy-fruited crops:
⢠Growing the vines on a trellis will keep them out of pathways.
⢠Trellising makes fruit easier to find, speeding and improving the ergonomics of harvest.
⢠Trellised vines can be grown at a higher density than vines that are sprawled, since they can make use of the vertical space over the plant, instead of growing into each other â which optimizes yield.
These are just some of the reasons why taking the time up-front to choose and set up a trellising system pays off in the long run. An additional plus is the improved airflow between plants that makes them less susceptible to disease pressures, and the resultant cleaner, premium-quality fruit they produce.
Here's a primer on the main types of trellising, how to determine which system to use, and all you need to get set up, so your crops â and what they yield â can climb high.
