July garden tips:

Crusted Soil:
Heavy summer rains can cause bare garden soil to form a crust. Lightly scratch the soil with a long-handled cultivator to loosen the soil and allow air and moisture to pe*****te. Mulch can become matted and should be loosened as well.

Propagate Shrubs with Cuttings:
Take softwood cuttings of shrubs such as buddleia, weigela, rose-of-sharon and roses. Place them in pots of moist sand or potting soil, then cover them with a plastic bag, glass jar or large plastic pop bottle, creating a mini-greenhouse. When strong roots have formed, move to a protected spot in the garden.

Do Not Fertilize Your Perennials:
At this time of year, most perennials neither need nor want to be fertilized. An exception would be delphiniums which will appreciate a feeding after their first bloom period. Use a balanced organic, water soluble fertilizer.

Moisture + Heat:
The combination of lots of moisture followed by heat will cause w**d and flower seeds to germinate quickly and prolifically. Pull the w**ds and unwanted seedlings when they appear. The garden will look tidier for your effort and the unwanted seedlings won’t be taking nutrients away from your plants.

Check out our newest youtube video on How to identify and remove Creeping Bellflower (Campanula rapunculoides) - an invasive plant in Ontario.

Creeping bellflower (Campanula rapunculoides) is an invasive garden plant that can spread through underground roots and seed. In this video, we show how to identify creeping bellflower and share practical approaches to managing it in a garden setting. Understanding how this plant grows can help gardeners make informed decisions about how to handle it over time.

Invasive plant awareness - creeping bellflower (Campanula rapunculoides)

This bellflower has purple flowers and will eventually take over flower beds, crowding out other perennials, and then spread into the lawn. This plant spreads via both seed and rhizome. It is impossible to keep it from spreading.

The best way to get it out is to dig it out entirely (including all roots), but in some areas this is not possible. It can be cut as close to the ground as possible (before going to seed) to inhibit spreading.

This invasive plant is included on the Ontario Invasive Species list and you can find other alternatives (if you like the purple flowers) that are not invasive on the Grow Me Instead website.

Use two hands or a pair of secateurs when picking peas and beans. The top should come off with the bean/pea rather than being left on the plant. Pulling the beans/peas off with one hand will often result in breaking a branch off the plant or pulling the entire plant out of the ground. Pick often to encourage the plants to continue to produce fruit.
