Dianthus Winter Care

Dianthus plants have pretty pink flowers with pink petals that are known for their spicy scent.  They start blooming in the spring and can even still be producing blooms into the fall months depending on your growing zone.  They are easy to overwinter and survive freezing temperatures with a few simple steps.  You need to cut your plants back to the ground and protect them with a layer of mulch.  This will protect your tender plants and help them to spread out and produce more beautiful flowers once the temperatures begin to rise in the spring.

Protecting Dianthus in Winter

Protect your dianthus plants in the winter by covering them with a thick layer of natural mulch.  This can be shredded leaves or bark mulch.  If your plants do become covered by snow this added layer of insulation will help protect them and keep them from freezing.  You may also want to mark where your plants are so in the spring they are easy to find.  Dianthus will spread out and can be used as a ground cover so you may not need to worry about where they are, once the temperatures warm up you will quickly know.

Cutting Back Dianthus For Winter

When your plants are finished blooming for the season in the fall.  All you need to do to get them ready for winter is to cut them back to ground level.  Do not worry about damaging your plants; a good cutting will help them put all of their energy into developing a strong root system and surviving the winter. 

Dianthus Winter Care in Pots

If your dianthus is planted in containers they will need to be cut back for the winter.  If they are the only type of plant in the container you can leave them outdoors.  Move your pots to where they are protected and you may want to cover them with a layer of shredded leaves or bark mulch that can be removed in the spring.  If they have been planted with other types of flowering annuals and perennials you may need to remove the annual plants and also prune or cut back the other ones getting all of them ready for winter. 

Watering Dianthus in Winter

Dianthus does not require a lot of water during the winter months, especially if they are covered with snow and ice.  You just want to make sure the plants stay moist and do not dry out.  If they are planted in containers just make sure the soil is moist enough to keep plants healthy but because they are in a dormant stage you do not have to water them as much as you would during active growing and blooming seasons like the spring, summer and fall.

Growing Dianthus Indoors

If your plants are blooming and you would like to enjoy them indoors for a few weeks this can be done but dianthus really is an outdoor plant.  The amount of sunlight that they require is just not possible indoors.  They are also not a winter blooming plant for most growing zones.
