Greenhouse Production Of Perennial Plants

Consider greenhouse production of perennial plants for growing  strong, healthy perennials. Once established, you'll plant them once and enjoy a gorgeous flowering garden for decades!

greenhouse production of perennial plantsPerennials are plants that live three years or longer. Perennials are grown for their beautifully colored flower blooms, and are commonly planted as borders. Many are perfect for cut flowers.

Greenhouse production of perennial plants has been on the rise in recent years, with good reason. If the perennial will survive winters in your planting zone, it is said to be "hardy" to that zone.

If the perennial plant is not hardy in your zone, they are said to be "tender" perennials. These tender plants can be wintered in your greenhouse by digging up their roots and storing them at cool temperatures.

Perennial flowers all vary as to their needs. It's a good idea to group your perennials as needing:

  • full sun

  • sun and partial shade, or

  • full shade

As you start perennials from seeds or as seedlings, they may not be established enough to take much freezing. This is one instance when resorting to greenhouse production of perennial plants has been a real boost to gardeners.

When To Apply Greenhouse
Production of Perennial Plants

Some perennials need cold winter temperatures, while others do not. Keep your greenhouse temperature around 40°F (5°C) or even a little lower while you're establishing them over the winter months. This will give them the cold they need, which helps their blooms.

If your local temperature rises above freezing during the winter months, a good option for perennials is a greenhouse with roll-up sides. This feature allows the perennials to be kept at the same temperature inside as it is outside.

Begin by heating the greenhouse to 50°F until all of your plants are well rooted. Slowly lower the temperature to 35°F. This cool, above-freezing temperature during the winter will improve plant development and flowering during the growing season.

The longer days of spring get perennial plants growing again, so the sooner in the fall you can give them cool temperatures, the better. Keep them fairly cool even when they start growing, otherwise they might grow too fast, or bloom before you can safely set them out.

Perennials come up year after year, as long as conditions for their blooming are favorable. Find out more about greenhouse production of perennial plants - and learn how easy it is to get started growing plants in a greenhouse.
