I have Morning glory, sunflowers, Dahlia's, columbine and poppies sitting on a windowsill. They are still very young, they only germinated about 3 days ago. The leaves on the MG are starting to turn a creamy colour and getting leggy.
The temperature outside is starting to pick up, and the weather is much nicer and sunny. Could I put them outdoors during sunny days and bring them in at night? Or will they die because they are so young/fragile?
