These plants spread quickly, creating mats that can reach up to 30 inches wide. This spreading nature, though good for covering large areas, can spread outside of their intended growing areas. The species is considered an invasive weed in some areas. Creeping speedwell are deer and rabbit resistant. They are susceptible to root rot or other fungal problems if the soil is kept too wet. Take note that the dense mats created by the plants may harbor ticks and fleas.
Light
Creeping speedwell can be grown in both full sun and shade. However, full sun can be too intense for creeping speedwell when it is grown in warm climates. Plants grown in full shade often do not flower well. For the best growth and bloom, it is ideal to plant creeping speedwell in an area with partial shade, particularly in the afternoon.
Soil
Creeping speedwell is a hardy plant frequently found growing in lawns, fields, and meadows. It prefers loamy, sandy, well-draining, and moist soil, but can also tolerate some clay. These plants grow best in soil with a neutral pH level, though they can tolerate slightly acidic and slightly alkaline soils.
Water
Once established, creeping speedwell is considered drought-tolerant. To avoid problems with soggy soil, only water these plants when the top inch or so of the soil begins to dry out. For young, newly planted speedwells, it is best to water more often until they are established. An inch of water per week is plenty to keep established plants healthy.
Temperature and Humidity
This groundcover plant is adaptable to a wide range of temperature and humidity levels, as long as it is grown within USDA hardiness zones 3 to 9. Keep in mind that the plant will remain evergreen in warm weather climates, but not in places where more seasonal changes in temperature are expected.
Fertilizer
Creeping speedwell is a light feeder and can even be grown in poor soil conditions, so regular fertilizing is not necessary. However, you can work compost or a well-balanced fertilizer into the soil in early spring if you want to ensure the plant receives needed nutrients.
Pruning
Pruning is not necessary, though it may be desired to keep the plant from spreading. Simply trim the plant with garden snips to do this. For large areas of creeping speedwell used as ground cover, a lawnmower is the best way to make quick work of the job. However, if you do not want the pruned pieces to take root, it is best to use a collection bag when mowing these plants. Stop pruning in late summer, especially for plants grown in areas with cold winters. This allows the plants to create enough mature foliage to be protected through the winter. Pruning too late in the year will result in new growth that is too tender to survive the winter.
Propagating Creeping Speedwell
The spreading nature of creeping speedwell makes these plants easy to propagate. It can be accomplished by means of division, cuttings, or layering. Division is a great option for plants whose centers begin to look bare or scraggly. To divide the plant, you will need a garden shovel, a hand shovel, a pair of snips, and a pair of gardening gloves. Then follow these instructions: To take cuttings, you will need a sharp pair of snips, moist, well-drained soil, and a small pot. Then follow these instructions: To layer, you will need a pair of garden gloves, a hand shovel, and a pair of snips. Then follow these instructions:
How to Grow Creeping Speedwell From Seed
Creeping speedwell can also be grown from seeds, started either indoors and outdoors. For indoor growth, start the seeds eight to 10 weeks before the last frost. You will need small pots, bright, indirect lighting, and a moist, well-draining seed starting mix, such as a peat moss mixture. Then follow these instructions: To start seeds outdoors, follow these instructions:
Potting and Repotting Creeping Speedwell
An easy way to contain creeping speedwell is by growing it in a pot. When choosing a container, be sure it has free-flowing drainage holes, as soggy soil can cause fungal problems. Since creeping speedwell will spread and fill the pot, at some point you will need to divide the plant or place it in a larger pot. When this time comes, tip the pot onto its side and tap it on all sides in order to loosen the roots. Slide the plant out when possible and either place it into a larger pot with loamy, well-draining soil, or divide the plant with a shovel or a pair of snips.
Overwintering
When grown in its appropriate growing zones, creeping speedwell does not require extra attention to survive the winter. Just be sure the soil does not get too wet, as this can lead to problems that may kill off the plant. If the winter is especially wet, you may want to cover the plant with plastic to keep some of the water out.
How to Get Creeping Speedwell to Bloom
Creeping speedwells produce small, four-petaled flowers seen in blue, purple, and pink. They often have white centers. Unlike other species of Veronica plants, creeping speedwell produces one flower per stalk as opposed to a spiky raceme covered in flowers. Still, these tiny flowers are attractive to pollinators such as butterflies and bees. Because of their hardy nature, creeping speedwells do not often need much help to bloom. To encourage blooming, be sure to choose a planting spot that receives a few hours of sunlight each day. An area that receives morning sun and afternoon shade is ideal. Deadheading spent flower blooms will encourage more flowers to form.
Common Problems With Creeping Speedwell
Creeping speedwell is a very hardy plant and does not present many problems. In fact, it is more likely to challenge the gardener with problems of overgrowth. However, even extremely hardy plants may occasionally face problems. The biggest issues for creeping speedwell plants occur when the soil is too wet or too dry, manifesting in the form of wilting, soggy, or yellowing foliage.
Wilting Foliage
This is often seen in hot climates where the soil dries out quickly. If this is the case, try to plant your creeping speedwell in an area that receives afternoon shade. Increase the amount of water and frequency of watering times to ensure the plant receives enough.
Soggy, Wilting, and Yellowing Foliage
This is a sign of too much water and may point to root rot. If this is the case, cut back on watering and only water when the first inch or so of the soil is dry. If root rot is suspected, dig up the plant and cut away any infected roots and foliage. Amend the soil with a well-draining material such as sand or compost before replanting.
