June garden jobs

Direct sow cucurbits once soil genuinely reaches 15-16C, not before.
Mulch after the soil has warmed to conserve moisture through July and August.
Start succession sowing salad and beans every two to three weeks.
Stake and support tomatoes now, while the plants are still small.
Take advantage of long daylight — June growth is the fastest of the year.

Common June mistakes

Mulching before the soil has warmed, which locks in the cold.
Sowing cucurbits into cold soil rather than waiting or using plastic.
Planting a single large sowing of lettuce that all matures at once.
Underestimating how fast growth is in June and letting supports fall behind.

Frequently Asked Questions

What can I plant in June in Canada?

Cucurbits, beans, corn and succession salad everywhere, plus fall brassicas started indoors in the long and medium bands.

Why does my garden grow so fast in June?

Day length. Northern Canada gets 16-18 hours of daylight in June, which drives very rapid growth and partly compensates for the short season.

Is it too late to plant tomatoes in June?

Early June is still workable in most of the country if you use transplants rather than seed and choose a short-season cultivar.
