How Toronto Weather Can Affect Flower Delivery (and What We Do About It)
Toronto is famous for its unpredictable weather, and if you’re sending flowers, the temperature matters just as much as the bouquet itself. From freezing winters to humid summers, the city's climate can be tough on delicate petals. No one wants to receive a wilted or frozen delivery, which is why we have to plan ahead for every season. In this post, we’ll look at how Toronto’s weather affects your floral gifts and the simple steps we take to keep them protected and fresh from our shop to your front door.
How Does the Weather in Toronto Affect Flower Delivery?
Toronto experiences some of the largest temperature swings in Canada. For flowers, these changes are more than just uncomfortable; they can be life-threatening.
The deep cold is the flower's enemy. When temperatures fall below freezing, the water inside a flower’s cells can actually freeze. This causes the cell walls to burst, resulting in what florists call freezer burn. Flowers exposed to the biting wind for a few minutes can develop petals that turn black, transparent or mushy.
In the summer, the problem becomes one of excessive heat and humidity. High temperatures make flowers exhale more rapidly, a process called respiration. The faster this process occurs, the quicker flowers deplete their energy stores, so they wilt before their time. Humidity can also trap moisture against the petals, which could cause mould if the arrangement is not well ventilated. Even a short walk from the shop to the delivery van can damage flowers if the hand-off isn’t managed well.
How Do Florists Keep Flowers in Deliveries Fresh and Alive?

1. Insulated Protective Wrapping
When the wind blows in Toronto, we don’t just put flowers out in a thin layer of plastic. In the winter months, we use multiple layers of heavy-duty paper and special floral sleeves. This creates a pocket of air around the blooms that is trapped, like a winter coat. On particularly cold days, we might even use insulated box liners to reflect heat back toward the flowers, ensuring they stay at a safe temperature until they are safely inside the recipient's home.
2. Climate Controlled Transport
The delivery van ride can be the most dangerous part of a flower’s journey. To fight this, professional florists employ climate-controlled vehicles. This means maintaining a consistent temperature inside the vehicle, generally between 1°C and 4°C for most bouquets, or slightly warmer for tropical types such as orchids. We also maintain a consistent environment, so there is no “shock” of going from a warm shop to a cold street and back again.
3. Hydration Solutions and Gel Packs
The stems need to stay hydrated, especially during Toronto’s hot summers. At the base of the stems, we often use hydration packs or water-soaked wraps to ensure the flowers have something to drink throughout the trip. If the heat is extreme, we might include small gel ice packs (non-toxic) with the packaging. They are placed carefully so they do not touch the petals directly, keeping the air inside the box cool enough to prevent wilting.
4. Smart Delivery Timing
Weather-aware delivery means we’re smart about when and where we drop a package off. We do early-morning deliveries in case of a heatwave or severe winter weather, when conditions are more manageable. Most importantly, we do not leave flowers on a porch or in a lobby if the recipient is not home.

Frequently Asked Questions
Can flowers be delivered if it's freezing outside?
Yes, we can deliver in cold temperatures. We use special winter packaging, like thick paper wraps and insulated sleeves, to protect the flowers from the cold as they go from the van to the door.
Will my flowers wilt in the heat?
Not if the flowers are handled properly. We use climate-controlled methods and hydration wraps on the stems to keep the flowers cool and hydrated from the moment they leave our shop until they arrive at their destination.
Should I take off the wrapping as soon as the flowers arrive in the winter?
Once it’s inside, it’s actually best to leave the bouquet in its wrapping for about 15-20 minutes. This means the flowers adjust to indoor temperatures slowly, so there's less chance of temperature shock.
