Can I Put My Seedlings Outside During the Day?
Spring is in the air, and with it comes the urge to get our hands in the dirt and start planting. If you’re like me, you’ve probably already started dreaming about those beautiful flowers and juicy tomatoes. But before you can move your seedlings outside, you need to make sure that they’re ready.
Hardening off your seedlings is essential for their survival outdoors. This process involves exposing them to gradually increasing levels of sunlight and wind over a period of 7-10 days. By the end of the hardening-off process, your seedlings should be able to withstand full sun and wind without wilting.
When to Start Hardening Off Seedlings
The best time to start hardening off seedlings is when they have developed their first set of true leaves. True leaves are the second set of leaves that grow on a plant, and they look different from the first set (cotyledons), which are often round or oval.
If you live in a warm climate, you can start hardening off seedlings as early as March or April. If you live in a cooler climate, you may need to wait until May or June.
How to Harden Off Seedlings
To harden off seedlings, you need to gradually expose them to sunlight and wind. Start by placing them outside for a few hours each day, in a sheltered area. Gradually increase the amount of time they spend outside each day until they are able to stay outside all day without wilting.
It’s important to protect your seedlings from direct sunlight and high winds during the hardening-off process. If the weather is too hot or windy, move your seedlings back inside or put them in a sheltered area.
Tips for Hardening Off Seedlings
- Start hardening off seedlings when they have developed their first set of true leaves.
- Gradually increase the amount of time seedlings spend outside each day.
- Place seedlings in a sheltered area, protected from direct sunlight and high winds.
- Water seedlings well before placing them outside.
- Be patient, as the hardening-off process can take up to 10 days.
Expert Advice
“Hardening off seedlings is an essential step for their survival outdoors,” says gardening expert Margaret Roach. “By gradually exposing them to sunlight and wind, you can help them to develop the strength and resilience they need to thrive.”
Roach recommends starting the hardening-off process early and gradually increasing the amount of time seedlings spend outside each day. “Don’t rush the process,” she says. “If you expose seedlings to too much sunlight or wind too quickly, they will wilt and may not recover.”
Roach also recommends protecting seedlings from direct sunlight and high winds during the hardening-off process. “If the weather is too hot or windy, move your seedlings back inside or put them in a sheltered area,” she says.
