Planting Cerastium Tomentosum
To grow healthy and happy, Cerastium tomentosum needs soil that works best with its demands and sensitivity to over-watering. Because of this, it would be wise to plant your flower in a substrate that features very sharp drainage and has a pH between 6.0 and 7.0. If you can find a well-draining soil for your Cerastium tomentosum, it does not really matter what other characteristics it has. Luckily, even if this plant does well in sandy growing mediums, it can also adapt to a wide range of soils.
Snow-in-summer usually appreciates poor soils, so it will not need regular fertilizing to show all its splendour. However, in case your plant does not seem to perform the way it should, you can intervene to give it a hand. Feed your Snow-in-summer with a good-quality fertilizer that is high in phosphorus once every year right before it blooms, typically in early spring.
Once its blooming season has come to an end, in summer, we recommend you remove all the spent flowers and some of its foliage. You can prune your plant using a garden pair of scissors or a sharp knife. This process will help your Snow-in-summer keep its spectacular appearance for the rest of the year.
Watering Cerastium Tomentosum
Cerastium tomentosum has very few watering demands, making it a great choice for gardeners that are at the beginning of the road. And if you are the forgetful type, it is even better! This plant thrives in relatively dry environmental conditions, so it comes along with a fairly drought-tolerant nature.
In areas with regular rainfalls, we suggest you grow your Snow-in-summer in a sheltered spot where it can avoid soggy conditions or waterlog. When it comes to watering, you will have to check its soil in-between drinks using a moisture meter. Make sure you provide your Snow-in-summer with water only when the substrate has dried out completely.
The frequency of watering will vary depending on the region you live in and also the season. Keep in mind that Snow-in-summer generally needs more water during its active growing period and blooming than it does in autumn or winter. Humidity-wise, the lower are the levels, the better your Snow-in-summer will be.
Propagating Cerastium Tomentosum
In general, Cerastium tomentosum produces numerous seeds and will multiply itself without any extra effort on your part. Sometimes, this habit can get out of control, making the plant pretty invasive with time. If you want to prevent this from happening, you must always collect the seeds and sow them elsewhere in your garden. Likewise, you can sow some of the seeds in pots and gift them to your family members or friends. It is easier than it sounds!
The perfect time to sow the Snow-in-summer seeds is usually early spring. Put the seeds directly into the ground or pots, then cover them a bit with garden or potting soil. If the seeds receive lots of sunlight and regular moisture, germination will occur in two or three weeks. However, you should know that these young seedlings will not produce flowers until the following year or so.
Another method to propagate your Snow-in-summer is through division. Still, you will have to wait for your plant to reach maturity if you want to divide it properly. When the plant has stopped blooming, sometime throughout the summer, you can get into action. Dig your Snow-in-summer out of the soil, then divide its roots into two or three pieces. After this step, you can replant the sections absolutely anywhere you dream of. And that’s all!
