Temperature-wise, Evergreen candytufts are usually winter hardy in USDA regions 4 to 8. But in the cold areas, such as 4 or 5, the leaves of these plants are only semi-evergreen. Because of this, most gardeners that grow them in cooler climates use pine boughs to help their plants go easier through the winter. Make sure you place some pine boughs over your Candytufts in late autumn to provide them with shelter for cold, dry winds, and also to keep them evergreen.
In their natural habitat, Evergreen candytufts prefer to grow in dry conditions. Due to this, it is wise to place your plants in a spot with drier air. If the outdoor humidity is too high, you can grow your Candytufts in pots and keep them inside near an air vent.
Evergreen candytufts are typically carefree regarding fungal diseases and pest infestations. In fact, the only problem that can occur while growing and caring for these plants is root rot. You can easily avoid this issue by growing your flowers in suitable well-draining soil.
Planting Evergreen Candytufts
The perfect time to plant your Evergreen candytufts is usually in early fall. These plants grow at a pretty slow pace and bloom in spring. Planting your flowers in early fall will give them enough time to establish until next spring. As a general rule, make sure you plant them at about 6 inches (15 cm) apart to provide them with good air circulation and avoid overcrowding.
To grow healthy and happy, Candytufts need that kind of gravelly substrates that you can find in their native land. In general, these plants do well in soils that have excellent drainage and are more on the alkaline side. If you want to grow your flowers in pots, plant them only in those that also come with drainage holes at the bottom.
Although fertilizing your Evergreen candytufts is not really mandatory, it can surely promote abundant blooming. Because of this, you can feed your beloved plants with a slow-release fertilizer once every year in early spring. Look for those products that come with a combination of phosphorus-high and nitrogen-low values for optimal results.
Sometimes, these plants can become somewhat leggy, bringing them an overall unkempt appearance. But! Once their blooming period has ended, you can prune about one-third of their top foliage to keep them all nice and tidy. If your plants get too little, do not worry! Regular pruning will always spawn new, healthy growth with time.
Watering Evergreen Candytufts
The watering routine of Evergreen candytufts is nothing but a piece of cake, especially once they have settled in their new habitat. However, during their first year of growth after planting, your flowers will require more water than usual. Make sure you water your young plants whenever the top half of soil feels dry to the touch.
Once established, Candytufts are pretty tolerant of drought for relatively long periods. These flowers are great start-ups for beginners or forgetful growers mostly due to this irresistible feature of theirs. When these plants have developed a strong root system, they will generally thrive with drinks only once every week or so.
During the heat of the summer months, you will have to check the soil more frequently. After a few attempts, provide your Evergreen candytufts with water whenever the soil has dried out completely. In winter, they can typically do just fine if you water them once every two or three weeks.
Propagating Evergreen Candytufts
These flowers are so pure-looking and easy-going, it is quite hard to resist their charm. And you do not even have to! After all, what can be more enjoyable than surrounding yourself with lots of lovely plants? Go on, grab your gardening tools, and propagate your Candytuft flowers, because it is fast, free, and very rewarding!
Without a doubt, the easiest and most effective method to propagate your evergreen candytufts is through division. First things first, wait for the fall to come and dig your large, mature plants out of their growing medium. Once you have their roots in your sight, divide them into two or three sections. After this step, you can replant your tiny Candytufts in their permanent locations.

If you do not have Evergreen candytufts that are old enough for division, you can propagate them using stem cuttings instead. Look for healthy stems that are a bit longer than the others and cut about 4 inches (10 cm) off them using a sharp knife. Plant the cuttings in fresh potting soil, place the container in a warm, well-lit area, and water regularly whenever the soil is dry.
Although the stems will self-root, this method may take a while to show some results due to their slow-growing habit. But if you have a patient nature, you will encounter no problems while using cuttings.
We are sure that your family members and friends would also love some baby Candytufts. Do not forget to plant some of the divided sections or the cuttings in pots to surprise your dearest ones with an adorable present!

My candytuft blooms beautifully. However, I am getting a lot of dead looking undergrowth. Should I cut the candytuft way back like 4-6 inches to encourage new growth next spring? My winter tempts range from 15-20 degrees in the winter. Thank you! The plants are at least 10 years old.
