How To Grow Tomatoes in Canada | Food Bloggers of Canada

One of the most rewarding moments in gardening is when you enjoy your first vine-ripened tomato picked straight from the plant, still warm from the sun. A tomato grown by you. And in that moment as you realize how amazing homegrown food tastes, you vow to double the amount of plants you'll grow next season. Growing tomatoes in Canada isn't hard - it just requires a little planning and care.

There are so many different tomatoes to choose from. Different varieties are used for different applications — some are better for saucing while others are preferred for canning or juicing. We'll take a look at the different varieties and what they're best suited for.

What Are the Tomato Growing Basics?

Choosing and Prepping the Site For Your Tomatoes

Tomatoes like it hot so be sure to place them in a hot, full-sun location; a minimum of eight hours of sun exposure a day is best.

Work the planting site well and add amendments to the soil like compost and peat moss for long-time feeding and to lighten the weight of the soil, which is especially helpful with container grown tomatoes. If growing in containers use at minimum a four-gallon sized pot for each plant.

When To Plant Tomatoes

Also make note of the days to maturity on the seed packages or tomato seedlings and buy according to your growing zone and frost dates. For the very best results you want to get varieties that are best suited to your growing location. To get an extra early start on the season you can start the seeds weeks before you plan on moving them outdoors.

Support Tomatoes

Tomatoes like support, so be sure to get tomato cages at the garden centre. They're inexpensive and last for many years. They help hold the weight of the tomatoes and prevent the plants from falling over. They also allow for light to reach the inner parts of the plant.

It's best to set the cages early on in the season so the plants can grow into the cage. Trying to cage larger plants often results in damaging the plants in an effort to make them fit.

Tips For Watering Tomatoes

Be sure to water well and if you are growing in containers, water often. The water needs for growing tomatoes is high and you'll need to water container grown tomatoes daily during hot weather.

Feeding Your Tomatoes

A regular feeding schedule will help improve yields. There are fertilizers on the market specifically for growing tomatoes. Alternately you can feed them using compost from your own composting efforts at home.

What's the Difference Between Determinate and Indeterminate Tomatoes?

Tomatoes have two growth patterns:

  • Determinate tomatoes bloom and set fruit all at once and then die as their season is over; and,
  • Indeterminate tomatoes grow and produce fruit constantly and only die once frost arrives.

This information helps you better plan for the season. For example, if you'd like to do a large canning marathon, you'd be better off growing a selection of tomatoes that will ripen at the same time. Though be sure to grow both kinds to have a fresh supply of tomatoes the entire season.

What Are Some Common Varieties of Tomatoes?

Roma Tomatoes

Roma tomatoes are a type of plum or paste tomato. They're oval or egg shaped and are the preferred tomato for sauces and pastes as they're drier, meatier and have less seeds. Their texture is perfect for cooking because of the low moisture content, so they require shorter cooking and processing time.
