Perennials For Container Gardens

Perennials for container gardens and the best perennials for containers and planting perennials in a container, that is what this page is all about.

Growing perennials in containers for dressing up patios, decks or balconies is ideal, ecpecially if you don’t have any soil to plant them in beds.

I also like to place containers with perennials in beds and borders.

It adds an element of surprise, as well as forming great focal points that present seasonal and vertical interest.

Container gardening with perennials also permits you to grow plants that normally wouldn’t survive in your garden’s conditions.

Nearly any type of perennial flower can be grown in a container.

However, the best results come when you select those with a long season of blooms, or ones with attractive foilage when flowers fade.

TIPS FOR CONTAINERS

Check Out These Great Plant Containers by Plow & Hearth

Select containers that give perennial roots room enough.

Choose a minimum pot diameter of 12 inches, larger is better.

Wooden half barrels and stone, faux stone or concrete containers stand up to weather and are frost proof.

Extend the life of wooden containers by placing pieces of treated lumber beneath the planters to raise them above a constantly moist footing.

Terra cotta tend to crumble in regions with freeze-thaw cycles.

With large, heavy planters, situate the pot before filling it with soil and planting it.

I do recommend placing them on coasters with wheels, that way you can move them around easily.

Every container needs drainage holes in the bottom. Most plants will die if left standing in water.

If your container is lightweight, use a heavy item (gravel, rocks or brick) to prevent toppling during strong winds.


Perennial Design Pointers
Perennials For Container Gardens

The design principle of balance comes into play when selecting perennials for a pot.

A general guideline is that the mature plant height should not exceed mor than 1.5 times the height of the container.

So if your container is 18 inches tall, the perennials in it should grow no more than 27 inches tall.

Pay attention to the light needs (full sun, part shade, full shade etc) of perennials in containers so they have the same light.

Plan against winter damage by choosing perennials that are at least one zone hardier than your hardiness zone.

For example, if you garden in zone 5, plant perennials for container gardens that are hardy to zone 4.
