How to Harden Off Your Plants the Right Way

The first long weekend is coming up! And that’s usually the kick-off for most YYC gardeners. It’s early this year, so I’m offering some sage (get it?) advice to harden off your plants. Cause you can’t just buy ’em and plant ’em. They would die. And you would be sad.

🪴 Days 1–3: When temps are moderate (think above 10°C), place your plants outside in the shade for a couple of hours. Bring them back in before it cools off too much.
🪴 Days 4–6: Gradually increase their time outside and start introducing them to dappled sunlight. Still bring them in at night!
🪴 Days 7–9: Let them hang out in full sun for a few hours, slowly working up to a full day. By now, they should be staying out all day and only coming in if there’s risk of frost.
🪴 Day 10+: Your plants should be toughened up and ready to go in the ground or into containers full-time, weather permitting.

Remember, Calgary May Long is unpredictable (remember camping in the snow?) especially overnight lows. A little patience now means healthier, stronger plants all season long.
