Growing Sea Thrift

The growing requirements of Sea thrift will directly depend on the region you live in. But do not worry, gardener! You will see that this plant is very low-demanding in general, no matter how much experience you have in the gardening world. Thanks to its few demands, it is an excellent companion for every type of grower, especially for beginners.

In terms of lighting, Sea thrift can tolerate any kind of exposure from full sunlight to partial shade. If you live in the northern area, your plant will grow at its best under six to eight hours of bright and direct light daily. In southern climates, we recommend you grow this flower in a spot where it can receive lots of partial sun to partial shade all year round.

As a rule, Sea thrift can do well in a wide range of temperatures from the USDA hardiness zones 3 to 9. Still, if you want to give your plant the best time ever, make sure you provide it with slightly cooler temperatures of 60 to 65 °F (16-18 °C).

Luckily, Sea thrift will not typically encounter many issues when it comes to pest infestations or fungal diseases. The only thing that may bother your plant is crown rot. This disease occurs mostly during the winter months if you are growing your Sea thrift in soil with poor drainage. To avoid this from happening, a proper growing medium for your plant will be more than enough.

Planting Sea Thrift

In general, Sea thrift is not picky regarding its growing medium. If you plant it in sandy soil that comes with very sharp drainage, you will have no problem with this plant in the future. However, make sure that the substrate is not overly fertile because it will make your Sea thrift more susceptible to root or crown rot.

Before planting your Sea thrift, we suggest you mix 2 to 4 inches (5-10 cm) of compost or aged manure in the growing medium. This process will help increase water retention and also improve drainage and fertility. Likewise, you should feed your Sea thrift with a balanced liquid fertilizer twice every year − once in early spring, then again during its active growing season.

Since Sea thrift makes for a wonderful potted plant, but it is sensitive to waterlogging, it is wise to plant it in a container that has drainage holes. Sea thrift tends to grow at a very slow pace, so it will not need frequent repotting. In fact, you should transplant this flower in a larger pot only when it starts to outgrow its current one.

If you dream to have a full-blooming Sea thrift in your garden every year, regular deadheading is mandatory. Many gardeners remove all spent flowers from Sea thrift plants during their blooming period to keep them flourishing for a longer period.

Watering Sea Thrift

Sea thrift is a plant that loves moisture and it usually thrives when it receives regular watering. However, too much moisture or soggy conditions can easily result in root or crown rot, especially on non-established specimens. Because of this, you must adopt a certain, but basic watering routine to avoid any unpleasant surprises.

First things first, make sure you always check the soil’s moisture in-between waterings. When the top 2 to 4 inches (5-10 cm) of the substrate feels dry to the touch, you can safely provide your Sea thrift with another drink.

Propagating Sea Thrift

In general, Sea thrift plants look at their best when you plant them in groups or masses. In fewer words: the more the merrier! You can surround yourself with more of these superb flowers by propagating them through division, basal cuttings, or seeds. All methods are usually very effective and show spectacular results with minimal effort on your part.

The ideal time to divide your Sea thrift is in spring. All you must do is dig out your plant from the soil, divide its roots into up to three sections, then replant each part wherever you feel like it. Yet, keep in mind that you can divide your plant only when it has reached maturity.

If you want to propagate your Sea thrift using basal cuttings, make sure you are doing it only during the summer months. Look for solid, healthy stems and cut about 2-3 inches (5-7.5 cm) of them with a sharp, sterilized knife. For optimal results, dip the cut ends in rooting hormone. After this step, plant each cutting in fresh soil, ensure bright light exposure and provide with water regularly to maintain the substrate damp.

Starting your own Sea thrift plants from seed is a fast process, showing flowers in the second year after sowing. First, collect the seeds from the plants once their blossoms begin to fade. Secondly, sow the seeds above a fresh damp soil in either spring or autumn. If you keep the seeds in a well-lit, cold location and a constantly damp growing medium, germination will occur in several months or so.

Once you see these bewitching flowers and learn more about them, it is absolutely impossible to resist them.
