Start Your Seeds, Start the Season!
It's that magical time again — 2026 seeds are officially in stock at greengate Garden Centres, along with everything you need for successful propagation: trays, domes, soil, lights, heat mats, and more. But here's the secret — for many plants, now is the time to get growing.
Don't forget to check your seed packets — some varieties may suggest starting as early as 10–12 weeks before last frost, which for Calgary usually lands in late May.
So, grab your seeds, your propagation gear, and a cup of something cozy — gardening season has officially begun indoors. Let's grow, Zone 3!

Starting from Seed: How-To & Pro Tips
Starting your garden from seed isn't just cost-effective — it's deeply satisfying. Watching something sprout on your windowsill in January or February? That's pure gardener joy.
Whether you're a first-timer or brushing up after a break, here's how to get growing:
1.
Choose the Right Seeds (Start at the Right Time)
Not all seeds are created equal - some need 12 weeks indoors, others just 4. Always check the back of your seed packet for timing. Still unsure? Ask us, we're here to help.
2.
Use a Seed-Starting Mix (Not Regular Potting Soil)
Seeds need light, fluffy, well-drained soil to get going. Look for seed-starting mixes made just for germination — or ask us how to make your own.
3.
Light is Life
Seeds may sprout in the dark, but they won't thrive without strong light. South-facing windows work in a pinch, but grow lights make all the difference — especially in our dim winter months.
4.
Warmth Gets Things Moving
Most seeds germinate best between 21–24°C. A heat mat under your trays can speed things up and improve success — especially for peppers, tomatoes, and eggplant.
5.
Give Them Air
Once seedlings emerge, increase airflow. A small fan helps prevent damp-off (a fungal disease) and strengthens stems.
6.
Thin the Herd
When seedlings have a couple sets of true leaves, snip the weaker ones. It feels harsh, but it's necessary — only the strongest should stay.
7.
Harden Off Before Planting Out
WAbout a week before moving plants outside, start hardening them off — give them time outdoors in small doses to adjust to real-world sun, wind, and temperature shifts.
