People also ask, how do you harden off plants?
Here's what to do:
- Check your seedlings' frost dates.
- Stop indoor watering or fertilizing.
- Choose your first hardening off spot.
- Place your seedlings outside for an hour.
- Move your plants back indoors.
- Lengthen the hardening off time.
- Protect your seedlings as needed.
- Extend nighttime hardening off hours.
Furthermore, do you need to harden off plants? Hardening off should take a minimum of a week and may take up to two. Suddenly moving plants from a stable environment to one with wide variations in temperature, light and wind can seriously weaken plants. For most plants, start hardening off about a week before the final frost date for your area.
In respect to this, what happens if you don't harden off plants?
If you don't harden your plants, the tender plants will get burned by the sun, the shock of cold, or the wind. Some plants may recover from burn (even fully), but their growth will be set back a few weeks while they recover.
When should you cover tomatoes at night?
Use a Cover to Protect Tomatoes When frost or temperatures are in the forecast for overnight (mid-30s or even 40ºF), cover your tomato plants with clear plastic or a tarp.
