However, the plant can become invasive in certain situations, particularly if it’s overwatered or even over-fertilized. Luckily, wayward plants are relatively easy to pull.

Blue Star Creeper Care

This plant is stunning no matter where you put itfilling the borders of a pond or forming a low, dense mat between stepping stones. Additionally, it is easy to care for — here’s what you need to understand.

Light

Water

Following that, it becomes fairly drought-resistant. However, blue star creeper does not like to sit in water. So you’ve got to be cautious about where you plant it.

Avoid placing it in reduced areas that could be vulnerable to holding water . Despite its drought-tolerance, you still have to water it well during dry and hot weather to avoid death.

Soil

It prefers moist, well-draining soil which does not get overly hot in the summit of this day. As a ground cover, it works quite nicely when interplanted between larger trees, shrubs, or trees.

Fertilizer

It’s not a heavy feeder, so you don’t even have to fertilize provided you have quality dirt. Nevertheless, a program of a general-purpose lawn fertilizer before the growing season can help recondition your soil prior to planting.

Repotting

When growing in containers as an ornamental or houseplant, you can repot it will. When it starts to sew a marijuana, just divide it up into smaller pots, or size up your pot by about 1″ approximately.

Propagation

If you want to disperse Isotoma fluviatilis, there are two methods to take action : by dividing the root ball or seeds.

The root ball is easily divided. Gently scrape the soil from the roots by either using sharp pruning shears or your hand. Divide the root ball and then plant it in your preferred pot or in the ground.

The next way is rather complicated to perform. Everything you need to do is to let the seed pods dry on the plant, then crush them in an air-tight container to collect the seeds. As soon as you have the seeds, then sprinkle them on a moistened seed starting mixture.

Once the seeds are evenly dispersed on the seed mix, put a paper on the container. Be certain that you leave a small gap between the container’s top surface and the dirt. This will give your blue star creeper seeds a place to sprout.

Maintain the container moist and in partial sunlight for 7 to 15 days. When the seedlings reach the six-leaf point, plant them in the ground or your desired location.

Pruning

Taking into consideration the fact it isn’t native to the United States, it may spread rather quickly, making it invasive in nature.

This fast growth occurs when you over-water the plant or use more fertilizer than necessary. Consider using a deep landscape edging material to stop unwanted spreading, or you can hand pull any excess expansion easily.
