Frequently Asked Questions about Growing Roses in a Greenhouse
Many people who want to try growing roses in a greenhouse environment have some common questions. Here are answers to some of the most frequently asked questions:
What type of greenhouse is best for roses?
Roses do best in a glass greenhouse rather than plastic sheeting greenhouses. Glass allows more light transmission and holds in heat better during colder months.
Should I grow roses in containers or directly in the greenhouse soil?
Container growing allows more control plus you can move the pots around. But in-ground culture works too if you have very good greenhouse soil and drainage. Make sure to use pots large enough for the rose’s root size.
When is the best time to plant roses in a greenhouse?
The ideal times are early spring or fall. This gives plants time to establish roots before the main growing and flowering season.
How much space do roses need in a greenhouse?
Leave 18-24 inches between mini roses, 2-3 feet between floribundas and patio roses, and 3-4 feet between hybrid teas and grandifloras. More space needed for climbers.
Should I use grow lights for greenhouse roses?
Yes, grow lights are great for supplementing natural light, especially in winter. LED grow lights work well for roses. Provide 14-16 hours per day of combined natural and supplemental lighting.
What temperature is optimal in the greenhouse for roses?
Aim for temperatures around 75°F during the day and 60-65°F at night. Raising the temperature to 80°F or more can boost flowering.
How humid should the greenhouse be for roses?
Between 40-60% relative humidity is ideal. Use a humidifier or pebble trays to raise humidity if needed. Proper airflow will also help manage moisture levels.
Should I fertilize roses grown in a greenhouse?
Yes, fertilizing is important. Use a balanced organic rose fertilizer according to label directions. Apply monthly through the growing season.
