Dianthus Care Guide
Welcome to your Dianthus care guide! Here you will find all of our Growers' knowledge of how best to look after your Dianthus, and what to do if you get stuck.
Plant name: Dianthus
Latin name: Dianthus Caryophyllus
Varieties included: Dianthus Oscar
Dianthus are the perfect addition to outdoor spaces of any size. Their tonal blooms and hardy nature mean that they perform well in containers, hanging baskets, beds and borders all season long.
Their delicate scent enhances any area, and will delight any visitors!
Hardiness: Hardy perennial plant
What does this mean? Dianthus should survive the frosty nights of winter to continue to provide colour throughout spring, and if cared for, will return the following autumn.
Before You Start
If you are planting in a garden container, make sure it is clean and has drainage holes in the base. You will need a good quality compost, trowel, watering-can and gloves may also be useful.
When planting directly into a garden bed or border it is often best to lay out your plants still in the pots so you can make sure you plant them in the best place to get the overall visual impact you are wanting.
Once you have decided where the plant is going dig a hole a little bit bigger than the pot size in the garden bed / border.
Next, take the plant out of the pot. This can be done easily by squeezing the sides of the pot between your thumb and fingers, then releasing your grip on the pot. This helps the roots come away from the pot.
Then hold the plant by the base of the stem, close as possible to the pot and remove the plastic pot. Hold your plant by the root ball and position in the middle of the hole.
The top of the compost around the plant should be a little lower than the level of the bed / border. If you need to dig a little deeper take the plant out and make the hole a bit deeper.
Once the Dianthus plant fits in the hole you can twist it around to get the best side of the plant facing forwards. When you are happy with the position fill the hole back in around the root ball and firm the soil back in.
Finally give the garden plant a good water, wherever possible trying to avoid getting water on the flowers.
Avoid planting during the hottest parts of the day. They prefer to be planted during the cooler part of the day as this reduces their stress levels (and nobody wants to see her stressed believe us!)
Dianthus will be happy in any part of your garden, but they will thrive if you can find a spot that gets a little bit of sun for them.
Watering & Feeding Guide
Keep your Dianthus fairly well-watered, especially in warmer and windier weather, as the soil will dry out a bit quicker in these conditions. Make sure you don’t overwater though to prevent the leaves from moulding and being more prone to disease.
They will benefit from a feed every week or two, using a multipurpose feed.
Soil type: Dianthus can be planted in any type of soil. Use a potting mix compost for containers and hanging baskets for better moisture retention and drainage.
Deadheading will promote further flowering.
