Dig up the top 3 inches of soil in between the pavers using a hand spade or garden fork. Discard the soil in another area of the yard or place it into a compost pile.
Spread 3 inches of compost in the area between the pavers and smooth it out with the hand spade, recommends Augusta Chronicle.
Place a level on top of the ground and add additional compost to level the surface of the ground out until it is smooth and even with no dips. If you leave any dips, rainwater will collect in them and create mud holes.
Pick up a clump of mondo grass, such as from a purchased pot, and separate it into 50 to 100 small plugs. The grass spreads rapidly, so the plugs only require about four blades each.
Dig a hole large enough for one mondo grass plug, approximately 1 inch deep. Insert the roots of the plug into the hole and fill in the hole with soil. Repeat to plant additional plugs between the pavers, spacing each plug 6 to 8 inches apart.
Water the area thoroughly until the soil between the pavers is completely moist.
Looking like grass but really a member of the lily family, mondo grass forms clumps of curving, linear leaves, which work well as a ground covers in garden settings. Most often mondo grass is the species Ophiopogon japonicus, but another species, Ophiopogon planiscapus is also called mondo grass and has a variety with dark purple foliage known as black mondo grass. Grow these species of mondo grass in a fertile, moist, well-draining soil in partial sunlight exposures in U.S. Department of Agriculture hardiness zones 7 through 10.
Clip back the blades of mondo grass with a heavy-duty scissors or lawn clippers in early to mid-spring before new leaf growth has started. Make the cuts so that 1 to 2 inches of leaves remain on the plant. Do not allow the pruning debris to remain atop the mondo grass plants. This is the same technique used on lilyturf plants (Liriope spp.).
Water and fertilize the pruned mondo grass to encourage healthy, robust rejuvenation of leaves in mid to late spring.
Spot-cut or pull out any leaves or tufts of foliage that brown and dry during the growing season and into the cooler winter months. Do not over-water the mondo grass during winter so less foliage dies back from rot.
Evaluate the grass for damage in late winter or early spring, before new growth appears; Southern Living magazine suggests trimming mondo grass in late February. Remove sticks, twigs or debris that may interfere with a mower or string trimmer.
Set the lawnmower at its highest setting and ensure it has a sharp blade. Dull blades will shred the edges of the grass. Only use a lawnmower on even ground; string trimmers are a better choice for uneven or small areas.
Run the lawnmower over the mondo grass, avoiding nearby plants. If you use a string trimmer, cut the grass 3 to 4 inches above the crown.
Rake and dispose of the clippings, cleaning around the grass and removing habitat for insects and disease.
Monkey grass or Mondo grass, whose scientific name is Ophiopogon japonicus, is a grass-like perennial often used as a groundcover in shady locations. This member of the lily family is hardy in zones 7 through 11, and requires no mowing.
Leafspot on the monkey pod occurs when the Phyllosticta pithecolobii fungus attacks the tree. Spots develop on the leaves, eventually causing them to drop off the tree. Most cases do not harm the trees enough to warrant fungicides. Fungicides, however, can control the disease if you catch it before the leaves start dropping.
Three types of caterpillars–Melipotis indomita, Ascalapha odorata, and Polydesma umbricola–invade the monkey pod every year, eating away its leaves. Melipotis indomita causes the most damage. This disease is not life-threatening to the tree, however, as the monkey pod leafs out soon after losing its leaves to the caterpillars. Caterpillar damage does cause stress for a short period of time, increasing the risk of other problems such as borers.
Borers and Ants
Monkey pod roundhead borers, also called Xystrocera globosa, invade stressed trees, making large holes in the wood of the tree. Ants bore into the branches, causing leaf deformation and drop. Control these pests by applying insecticide to the trunk of the tree. Follow the directions on the package for safety and application instructions.
The leaves of the monkey pod plant are highly susceptible to salt spray and herbicide spray. Direct contact burns the leaves, causing injury and sometimes even leaf drop.
