The Light in Your Garden

by Chris Freeburn, Master Gardener

Growing any plant successfully in your garden depends on many factors and an important one is the amount of light you get throughout the day. Growing Hosta out in the blazing sunshine is fine when they first emerge in springtime, but most Hosta will fry with the hot summer sun all day long. A peony without enough sun will have lovely green leaves, but will probably not give you any flowers.

Take a day or two to notice when your flower beds are in sun and for how long. Full sun means at least 6 hours of sun a day. Full shade means no direct sun. Part sun should only be about 3 hours. Morning sun is the best as it is not harsh and hot like late afternoon sun, so if you have gardens facing east, you have the best light for most plants.

Knowing which direction your home sits is important too. Get your orientation fixed in your mind. Remember that trees and buildings will shade the gardens as the sun moves throughout the day. As the seasons change, the sun will move slightly in its orientation and where the sunlight comes from will change. Be prepared when you go plant shopping, read plant tags and talk to experts to be sure you are putting the right plant in the right place for the right light requirements.

Like growing just outside your garden growing zones, gardeners can also grow outside sun requirements. Hybridizing has enabled us to have plants that will grow outside their normal light needs. For instance, there are now Hosta that will take a lot of sun. Try to stretch the limits if you want that certain plant in that certain place, but remember to monitor it to be sure it is not being stressed and is performing at its best.

Lighting may change in your garden. If a big tree is removed, a full shade garden can become a full sun garden. As a tree grows in your or your neighbour’s yard, or if a new building goes up, it will become more shaded. You may find that you will have to relocate plants when this happens.

Spend more time in your garden, just watching. It is good for your education and good for your soul.
