New Guinea Impatiens Cool Tolerance & Dead Lawn Revival
I planted three New Guniea Impatiens in pots and grew them in partial shade. They're doing well; however, will they survive the winter, or should I bring them inside?
New Guinea Impatiens will not survive the winter months outside because of the cold.
They can be grown indoors; however, your biggest challenge is to keep them blooming and prevent the growth from getting leggy.
Both of these issues are related to the low light condition found in most homes. This may or may not be an issue depending on you're overall plan. If protecting them from the cold is your main objective, then it's not a big deal. All you need to do is keep them watered. You'll need to move them into a heated room, so a garage is not suitable.
They'll grow more compactly in cooler rooms kept under seventy-five degrees. In late March, you move them outside, cut back the growth and feed them.
I prefer Osmocote as you'll only need to reapply the nutrients every four months, but there are plenty of other excellent options. To keep them blooming indoors, you'll need a location that receives at least four hours of indirect or direct sunlight. This can be challenging during the winter months. The Agro Sunlight from Hydro Farms is a grow light that can help resolve this problem. It's available at many independent garden centers.
New Guinea's should survive outside as long as the nighttime temperatures stay above forty degrees, but I'd moved them inside by Thanksgiving to be on the safe side. Ultimately, it's a judgment call on your part. For me, it's not worth all the trouble to overwinter them.
NOTE: New Guinea Impatiens are a hybrid Impatient. New Guineas are generally grown from cuttings and have larger leaves and larger blooms, up to three inches across than the typical impatient.
My lawn is dead from the lack of water since I did not water it all summer. Is there anything I can do to help it come back this winter? It's really crunchy and brown with lots of bare spots.
Once the grass has turned brown from the lack of water, and there isn't a magic solution one can do to revive it other than to start over.
Many seasonal types of grass turn brown or go dormant during the summer months, but they still require some moisture. They'll green up in the late fall.
Once a grass gets to the straw color and crunchy, it's past the revival point. Reseeding a lawn now is not an option as the grass seed germinates poorly with the short days and cool nights. You'll need to wait until next March.
