How To Care

Spring or fall are ideal times to plant your Firewitch Dianthus. However, as long as you avoid extreme temperature you can plant almost any time of the year. Plant you Firewitch Dianthus in growing zones 3 to 8.

This Dianthus thrives in full sun and is adaptable to a variety of soil, as long as it is well-drained. Water deeply when planting and 2 times per week for the first 3 months while your plant is establishing. Once established, water your Dianthus when dry. Add 2-3 inches of mulch to prevent weeds and protect your plant's roots in extreme temperatures. Fertilize with our slow release fertilizer when planting and in spring. Deadheading isn't necessary, but it can increase blooms and extend bloom time.

Dianthus are deer resistant and pollution and salt tolerant. They are very hardy and low maintenance.

The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, watering, and fertilization are the keys to your success. Spider Mites and Aphids are potential problem insects for the Dianthus. These pests can be treated naturally with neem oil, or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. Dianthus can, on occasion, encounter fungal issues. Generally, treating after infection isn't extremely effective. So, if you have problems yearly treat in early spring with fungicides to prevent infection. Neem Oil is an organic method of treating and preventing some fungal diseases and pests. It can be effective, but the entire plant must be coated in order for this method to be effective. Always water at the base of this plant to avoid fungal disease on the leaves.

Beautiful plants

The plants showed up looking healthy and ready to bloom I had ordered 3 Firewitch dianthus because I loved the color of the bloom and had a full sun area that needed a tough and colorful plant. I ended up only planting 2 while my sister in law took one to plant in her yard. She has problems with deer and is hopeful that the deer will leave it

Lovely Plants

Healthy but Small'ish

Overall, we're quite pleased with our purchase and the ease of use of the website. Our only knock is the one gallon plants are a bit smaller than we expected. They were cleverly packaged and appear healthy. Hopefully, with a little growth we will be totally happy with the experience.
