Growth And Maintenance Of Perennial Dianthus Plants
Knowing the right growth process and care tips for the perennial Dianthus will save you from a lot of problems that might occur in the future.
For instance, knowing the right site for them to be planted will make your plants thrive and totally resistant to pests and diseases.
For Perennial Dianthus, it is best to commence planting once the cool months approach, usually during early Spring or Fall.
The art of dividing the plants should also be encouraged. This is because, as time goes on, old plants may begin to have dead spots at the foliage center. This is the point at which it needs to be separated.
You can get this done by cutting clumps into several places, settling down to remove the foliage's dead parts and replanting them into different spots.
Planting Site Requirements
Perennial Dianthus are best grown with a minimum spacing of about 6 inches and a maximum of 12 inches. This means the site has to be spacious enough to accommodate your plants growing at most 12 inches from each other.
The site also has to be one in which they are sure to get a good dose of sunlight. Perennial Dianthus require full sun or, at least, part sun to grow well. Planting them in a shady site would make for the production of lesser flowers and rotting of the crown.
Most Perennial Dianthus plants thrive best in rich and well-drained soil.
For best results in your perennial Dianthus growth project, have the soil loosened to about 12 inches depth and mix with 3 - 4 inches of organic matter, compost especially.
The essence of doing this is to fortify the soil with added nutrients, thereby making it richer.
Furthermore, ensure that the whole of the root ball is covered with the soil in order for them to adequately feed from its nutrients. Use your hands to tap the soil slightly around the plant’s base to solidify it and keep it in place.
Watering of the plants should be frequent in the hot months of the year, but during summer, watering the plants once a week should be sufficient.
Watering should only be done when needed as too much watering can lead to rot. Watering from above should also be avoided to prevent the leaves from getting mold.
Deadheading The Plants
Deadheading simply means the process of removing spent blooms. This process is necessary as it aids the production of much more new flowers.
To ensure a perfect establishment of your plants, see that they get a sufficient dose of fertilizer during the spring season especially.
The use of organic mulch is really not necessary for the growth of the perennial Dianthus. The use of graves and stone chips is advised instead to limit weeds. Organic mulch tends to lead to fungal problems and rot.
You might be required to have Perennial Dianthus variants with long stems staked to keep them from being bent but grow upright instead.
