Creeping Weed Plants
Creeping Jenny, also known as "moneywort" and scientifically as "lysimachia nummularia," is a hardy ground cover that gardeners often try to eliminate. Despite its negative reputation, creepy Jenny grows plentifully and is easy to plant, even in areas that cannot grow grass or other ground covers. Creeping Jenny has yellow flowers that bloom for several weeks in the spring.
Buy creeping Jenny seeds. They are available at your local nursery or gardening store.
Plant three seeds each in several small containers. Fill the containers with topsoil and press the seeds approximately 1 inch below the soil. Place in a sunny, warm window and wait approximately one month for the seeds to germinate.
Build a raised bed for your creeping Jenny seedlings. Although not a requirement, the bed will prevent the plants from taking over your garden. Create a box in your garden with four plywood beams nailed together to form a square. Fill the area with a combination of topsoil and peat moss.
Plant creeping seedlings after all signs of frost have passed--in shade, part-shade or full sun. Dig a hole with a trowel large enough to place the entire soil ball surrounding the roots. Pack extra topsoil around the seedlings and plant each one approximately 12 inches apart. Water the area thoroughly.
Water your creeping Jenny when the ground feels dry or when you water the rest of your garden. If not using a raised bed, weed creeping Jenny away from other areas of your garden; it can choke out other flowers and plants.
Dig up all of the offending spider grass plants. Be sure to remove all of the underground roots you can find. Even small root pieces can regenerate to form new plants. Discard all removed foliage and roots immediately.
Spray any re-sprouting plants with a glyphosate herbicide. Follow the manufacturer's instructions and coat all of the plant's foliage until just before the point of runoff. The sooner you spray the plants the better. Before you spray, protect any adjacent plants by covering them with plastic. Glyphosate is a non-selective herbicide that will kill any plant it touches.
Re-spray the plants once in spring, summer and fall until the spider grass stops coming back. This may take several seasons.
Fill the plastic bottle with the herbicide containing glyphosate.
Aim the sprayer approximately 5 to 7 inches away from the bentgrass and soak the blades with the herbicide. Be sure to spray approximately 4 to 5 inches outside the growth of bentgrass to kill spreading roots.
Allow the herbicide to break down the grass for one to two weeks and monitor the progress. If necessary, reapply the herbicide.
Remove grass from the area you're chosen to plant your liriope. Digging up as many roots and runners now will save you difficult weeding later. Crabgrass in particular can infiltrate liriope's thick clumps.
Choose a site that is either shady or sunny. According to the University of Florida Extension Service, liriope can tolerate no more than four to six hours of full sun in USDA zones 9-11. Liriope prefers a fertile and slightly acidic soil (ph 6.0 to 7.0), but it's really not very fussy and can thrive even in clay soil.
Dig a hole slightly larger than your plant's root system. Place the liriope in the hole, backfill with dirt and tamp down firmly to remove air pockets. Water thoroughly.
Mulch your liriope with pine needles or hardwood mulch. Water each week during the plants' first growing season. After that, you need water only in extreme drought conditions. Liriope does not like "wet feet."
Separate and divide liriope every 3-4 years. This will give your older plants breathing room and also give you new plants for your garden.
Where to Plant
This creeping perennial does well in well-draining soil along borders, in pots, or left to cascade over walls or banks.
Sanvitalia needs full sun or at least mostly sunny conditions, for optimal growing performance.
This ground cover works best in fertile, well-draining soil; and once established, it adapts to any soil condition.
Sanvitalia is a hardy, drought-tolerant sprawling plant that grows best when just left alone. No deadheading or pruning are needed.
A Mexican native plant, sanvitalia will bloom year-round in the Southwest. In cooler climates, it blooms in late summer.
Creeping zinnia spreads and trails along the ground. It reaches 6 to 12 inches high and about 2 to 3 feet in diameter.
Creeping zinnia likes full sun and light sandy soil with good drainage. It is drought tolerant but might have issues in intense heat in southern climates.
Primarily used as a ground cover, creeping zinnia also does well in rock gardens, cascading down a wall or in hanging baskets.
Creeping zinnia flowers are small, yellow and daisy-like. They produce prolifically from late spring through early fall and do not need to be deadheaded.
Propagation occurs from seeds sown on the soil surface after the last frost. This plant is half-hardy and is often treated as an annual.
