Zoysia grass is a popular warm-season turf known for its dense growth habit, fine texture, and resilience. The plugging method involves planting small, rooted sections of mature sod into the soil. This technique is often favored over seeding because the plugs already have developed root systems, providing a jump-start to the lawn’s development. Plugging is also a cost-effective way to establish a large area, allowing the grass to spread naturally over one or two growing seasons to form a uniform, lush carpet.
Preparing the Site and Timing Your Planting
Timing the installation correctly is crucial for successful establishment, as Zoysia requires heat to thrive. The optimal window for planting Zoysia plugs is from late spring to early summer, typically after the last frost and when soil temperatures are consistently above 65°F. Planting during this period ensures the plugs have maximum time to establish deep roots and spread before fall dormancy.
Thorough site preparation prevents competition and encourages rapid growth. Begin by removing all existing vegetation, either by mowing low and removing clippings or by applying a non-selective herbicide. Loosening compacted soil by tilling the top 4 to 6 inches promotes better root penetration and drainage. Zoysia grows best in well-drained soil with a slightly acidic to neutral pH, ideally ranging between 6.0 and 7.0. Conducting a soil test beforehand allows for the incorporation of any necessary amendments, such as lime or sulfur, ensuring favorable soil chemistry.
Step-by-Step Guide to Planting Zoysia Plugs
The mechanical process of planting plugs is straightforward, requiring a specialized plugger tool or a long-handled bulb planter to create a perfectly sized hole. The most common spacing recommendation is 6 to 12 inches apart on center, often in a staggered, diagonal grid pattern. Closer spacing, such as 6 inches, requires more plugs but dramatically reduces the time required for the lawn to knit together.
Use the plugger to remove a soil core, then insert the Zoysia plug into the hole. Ensure the top of the grass is level with the surrounding soil surface. The root ball should not be buried or elevated, as this prevents stolons from reaching the soil or causes the plug to dry out. Once the plug is set, firmly press the soil around it, often by stepping on it, to eliminate air pockets and ensure soil-to-root contact. Immediately water the entire area heavily and deeply to settle the soil and reduce transplant shock.
Essential Post-Planting Care for Successful Growth
The initial weeks following planting require specific watering practices to keep the root systems moist for successful establishment. For the first 10 to 14 days, keep the area consistently moist, often requiring light watering once or twice daily. As the plugs anchor, gradually decrease the watering frequency while increasing the duration of each session. This transition encourages roots to grow deeper, promoting long-term drought tolerance.
Delay fertilization until the plugs show signs of new growth, typically three to four weeks after planting. Applying a starter fertilizer at this stage provides nutrients, particularly phosphorus, to stimulate lateral spreading. Weed control is essential, as the bare soil between the plugs is susceptible to weed growth. Hand-pulling is the safest method, but a selective pre-emergent herbicide labeled for new Zoysia plugs can be applied cautiously. Avoid mowing for the first two weeks. Once rooted, begin mowing at a height of about 2 inches; regular mowing encourages the Zoysia to spread horizontally, creating a dense, continuous turf.
