In The Garden: Raided in a Bed
Tuck plants in for an extended season.
If you’re thinking of building a raised bed in your yard, urban gardener Tara Nolan has the answers to all of your questions. Nolan is an authority on this subject, and with all the changes in the business of gardening over the recent years, it’s great to have a comprehensive, go-to book on this very popular topic.
Early autumn is the perfect time of year to get handy and build a raised bed to plant in for this season, or in preparation for spring.
There are caveats to the raised bed phenomena. The roots of winterhardy plants are exposed to excess cold in the depth of winter. With this in mind, choose plants that are hardy in a planting zone one above your own. For example, plant winterhardy plants that are rated for Zone Five in a Zone Six Toronto garden.
Raised beds also tend to dry out more quickly than ground level beds. On the positive side, this can decrease the likelihood of over watering, which is at the root of 90 per cent of all plant problems. However, you do have to be vigilant about watering especially during hot, dry weather.
Tara Nolan is a Canadian writer. Her book is a comprehensive treatise on the subject, with a third of the book dedicated to DIY raised bed projects.

Why build a raised bed?
In her book, Raised Bed Revolution – Build It, Fill It, Plant It…Garden Anywhere, Nolan dedicates 12 pages of reasons as to why you might want might to build a raised bed for your veggies and ornamentals. Here are some of my favourites.
- Season extension
- Start earlier, harvest later. The soil in a raised bed warms up quicker come spring. If you have a glassedin structure around a raised bed, or use white Reemay cloth, you can extend the season for several weeks.
- Control soil quality
- People frequently ask me what they should do with clay soil. They’re never happy when I advise them to dig out 30 to 40 centimetres of the clay soil and replace it with 50 to 60 centimetres of new triple mix. When you build a raised bed in your yard, you don’t have to dig down and remove the soil. Fill the raised bed with the best quality, weed-free soil that you can get your hands on.
- At Wind Reach Farm (a centre designed to meet the needs of individuals with a variety of disabilities in Ashburn, Ontario), I saw some of the most practical, and handsome, raised bed gardens for wheelchair gardeners. If this is a consideration, be sure to design a wheelchair garden with a wraparound feature for the plants on the left, and a shelf for shallow rooted plants on the right, so that the gardener can belly up to the garden with their legs safely nested underneath.
