DIANTHUS PLANTS: HOW TO GROW DIANTHUS
What Is A Dianthus Plant?
The word “dianthus” comes from the Latin words “diana”, which means beauty, and “thusa”, which means vine or bush. The plant genus name, Thymus, means “wanderer”. The common names for these plants are “flowering vines”, “bushy flowers”, and “wildflowers.”
There are many different species of Dianthus, but they all have one thing in common: They’re related to each other. There’s even a type of Dianthus called a thimbleleaf dandelion (Thymus vulgaris). These plants grow wild throughout the world. They’ve been used medicinally for centuries.
How Do You Grow Dianthus Plants?
You can grow any kind of dandelions, including those with large leaves like the dwarf varieties. If you want to grow a small number of dwarf varieties, it’s possible to start them indoors in a pot.
If you want to grow a larger quantity, plant them outdoors in the spring once the weather is consistently above 50 degrees. The soil should be well drained, because dianthus plants don’t do well in wet roots.
If you live where it gets really cold in the winter, you can also grow dianthus plants as a perennial. If you live in zone 8 or warmer, dianthus are hardy perennials.
Most dianthus tubers can survive winter frosts as long as the soil doesn’t freeze more than a couple of inches deep. If you live where the winters get extremely cold, you can mulch around the base of the plants in the fall to protect them.
How To Care For Dianthus Plants:
Dianthus plants need full sun or light shade. If you grow them in shade, they won’t bloom as much. You can also grow them in partial shade and they’ll bloom a little bit.
These plants prefer well-drained soil with lots of organic matter. You can fertilize them with an all-purpose plant food or specific dianthus food.
Pinch the tips off when they’re about 2 inches high to encourage bushy growth rather than a tall, gangly look.
If you live where the nights get below 55 degrees in the winter, you can protect your plants with a thick layer of mulch. Remove the mulch in the spring when the weather gets warm.
How To Divide And Replant:
When growing dianthus, it’s important to divide and replant them every couple of years. Carefully dig up your plant and separate it into pieces with the largest being about 6 inches across.
