Sowing and planting tomato
It’s best to consider that tomatoes can only successfully be planted outdoors after May 15th, and that it is useless to start sowing them too early.
If sowing tomato from seed
Sowing tomato seeds must be done at the end of the winter, towards mid-March, indoors and with a temperature of around 65°F to 70°F (18°C to 20°C).
If you don’t have seed growing equipment, or if you are growing tomato for the first time, start with small seedlings purchased in a nursery.
- Refer to our page on sowing tomatoes and start indoors in February-March.
This method takes longer, but it is very easy to accomplish and you’ll be rewarded with a unique, delicious taste in the fruits you will harvest!
Did you know you could grow tomato seeds from scraps?
Planting and growing tomato purchased in nursery pots
This is the best way to start growing tomatoes, or at the very least save all that seedling-growing time.
If you purchase tomatoes in nursery pots, it means you’ll have purchased them in spring.
- Plant them in a sun-bathed area, sheltered from stronger winds, once freezing is definitely over.
- Space each plant around 30 inches (80 cm) apart.
For better tomatoes, add organic tomato fertilizer once or twice a month.
- Humus-rich soils, preferably mixed in before planting.
- Being exposed to the sun as much as possible.
- Regular watering, but without wetting the leaves to avoid diseases.

Pruning tomato, here is what to do
It is important that fruits be exposed to sunlight for them to develop correctly.
- Remove growth (they’re called “suckers”) that may sprout where the leaves are connected to the stem.
These “suckers” tend to absorb a lot of sap, and this slows the growth of the plant.
- When the plant has reached its maximum height, prune the head off, leaving 4 or 5 groups of leaves.
Tomatoes can generally be harvested starting middle of August, and harvest can continue till the end of fall if the climate stays mild.
- Tomatoes are best harvested only once they are well colored.
Usually this takes 4 to 5 months of growing, from the moment seeds started sprouting.
- Some fruits might mature very late in the season.
- You can harvest them if still green and let them ripen in your garage or on a windowsill.
- With green tomatoes, you can make delicious green tomato jam.
Don’t stop at harvesting tomato – save tomato seeds for next year’s crop!
Diseases and parasites that attack tomato
There are various common diseases that attack tomatoes, often types of fungus that can be avoided if basic rules are followed.
You can find the best advice for each disease by clicking on the links for each of these diseases.
- Tomato blight – Black spots on leaves.
- Powdery mildew – white velvet covers leaves.
- Aphids – leaves curl up.
- Early blight – Treatment for early blight is the same as for tomato blight
- Late blight – also called Septoria leaf spots
- Whiteflies – Tiny flies gather on the underside of leaves. A plant-based insecticide must be sprayed on the pests, or nasturtiums can also be planted at the foot of your tomatoes.
- Tomato pinworm – pinworm larvae dig tunnels on both stems and leaves of the tomato plant.
Take note that copper-based treatments such as Bordeaux mixture applied as a deterrent help avoid most of the diseases that impact tomato growing.
