The general rule of thumb is that when a seedling has three to four true leaves, it’s large enough to plant out in the garden (after it has been hardened off).
Similarly, when should you move seedlings outside?
You can start to harden off your seedlings once they’ve grown at least two to three sets of leaves. At that point, they’re mature enough to move outside. About 7 to 10 days before your seedlings are ready to be transplanted, take them outside and leave them in the shade for a few hours in the morning or afternoon.
Hereof, how do you transplant plants without killing them?
How to Move Your Garden Without Killing Your Plants
- If you are able, choose the season you move.
- Mark where everything is going to go first.
- Pot, bucket or burlap: get the transportation ready.
- Use a special watering schedule for soon-to-be in-transit plants.
- Trim excess stems.
- Dig up using the drip line.
When seedlings become ready for transplanting?
The ideal time for transplanting your seedlings is about 3 weeks after they sprout or when you have 1-2 sets of true leaves. It’s better to get them in new containers before they start to show the signs of stress listed below.
If temperatures remain warm both day and night (at least 50 degrees Fahrenheit), the seedlings should be able to handle increasing amounts of sunlight and can be left outdoors overnight. Make sure the soil doesn’t dry out if temperatures should suddenly turn warmer.
