There are many benefits to planting perennial flowers in your garden. Perennials are less maintenance than annuals, typically heartier, and can bring a variety of shapes and colors to your garden plot or greenhouse. It’s important to understand the differences between perennials and annuals before mapping out your dream garden. Explore important facts about perennials below to get started growing this year.

Perennials vs. Annuals

Perennial plants can be planted from seeds or bulbs. They are defined as plants that grow for more than one season, in comparison to annuals that will die after one growing year. Perennials typically blossom in the springtime, although this varies depending on the specific type and variety. They also usually bloom for less time than annuals do. However, because perennials come back year after year, they are often heartier, with stronger stalks and root systems. These root systems allow some perennials to be great at conserving water through times of drought, and they’re often able to survive periodic dry spells.

Tips for Healthy Perennials

When growing perennial plants, there are several things to consider.

  • Dig a hole that is twice as wide as the pot, and 6” (15cm) deeper.
  • Incorporate TERRA Plus 3 Mix with the soil you dig out of the hole.
  • Place about 6” (15cm) of this soil mixture back into the hole.
  • Water your plant thoroughly and remove it from the plastic pot.
  • Loosen the roots gently with your fingers if they appear crowded.
  • Place your plant in the hole.
  • Fill in around the root ball with your soil mixture.
  • When you are done, the soil that the plant was grown in should be even with existing ground level.
  • If your new plant is in a burlap sack or fibre pot – do not remove. Simply place the plant and pot directly into the hole following these directions:
  • If your plant is in a burlap sack, untie the twine from around the trunk of the plant, and fold back the top 1/3 of the burlap. Cover with soil.
  • If your plant is in a fibre pot, cut the top 1/3 of the pot away and fill the hole in with soil.

 

  1. After initially planting your perennial plants, water them significantly. Then, add a layer of approximately 3 inches of TERRA Plus 3 soil around the roots of your new plants. This will allow them to retain some of the moisture longer.
  2. You may need to consider giving your taller perennial plants some additional support in the form of a plant stalk. If you’re on a budget, make your own stalk out of an appropriately sized stick and simply tie a loose string around it and the stem of your perennial.
  3. Be sure to consistently dead-head your plants. This simply means taking off the top of a specific flower on your perennial that has gone by. By dead-heading, your plants will re-grow stronger and more healthy flowers.
  4. After your growing season has ended, consider laying a layer of mulch down over your perennials. Perennials don’t typically require special care at the end of the season, but it doesn’t hurt to give them additional protection from snow and other elements.

Now that you have explored the perennial plant definition above, as well as tips for growing healthy perennials, you’re equipped to start planning your perennial garden! Visit TERRA Greenhouses for additional information and growing tips for successfully growing healthy perennials.
