Maintenance
Routines that keep the court in top condition all season. Little and often — not big clean-ups. Konglungen's 40 mm profile requires precision, but responds quickly when routines are in place.
Players' responsibility — after each day of play
- Close all ball marks / holes with your foot immediately — especially at net and baselines
- Circular dragging: Start at the outside, work slowly toward the middle in large circles
- Extra focus on high-wear zones: Behind baselines, service boxes and mid-court
- Check moisture level — dry = dusty, but avoid overwatering
Grounds team tasks
- Light rolling (1–2 times) if the court feels loose or uneven
- Local top-ups with 0–2 mm where the surface opens up — especially in high-wear areas
- Thorough circular dragging — remove loose material collected along the edges
- Adjust watering: 10–20 minutes per court morning/evening in dry periods (spray up into air, not straight down)
- Check lines, net, posts and drainage — report issues if anything is loose
Grounds team + volunteers
- Full check of slope and evenness — straightedge / level check
- Larger spot repairs with 0–3 mm if settlements or depressions appear
- Clean court edges and drains to secure drainage
- Review material usage — order additional clay in good time (typically 2–4 tons mid-season)
Green growth: right product, right zone
Green growth on a clay court is typically algae, moss and weeds — and they require different treatment. Do not use Roundup on the playing surface: it does not effectively kill algae, can bind to the clay and make the surface more slippery.
UgressNIX Effekt (pelargonic acid) + brushing.
- Spray on a dry court in sun
- Light brushing before spraying
- Do not water afterwards — let it work
- Brush again after a few days
- 1–2 treatments per season is enough
Roundup (glyphosate) here only — effective against deep roots along fences, behind benches and in border zones.
- Not on the playing surface — does not kill algae and can cause a slippery surface
- Water more often — morning and evening
- Drag more gently to avoid dust
- Consider a very thin extra 0–2 mm top-up if the surface breaks down
- Reduce irrigation — let the weather do the work
- Increase dragging to avoid a slick surface
- Check drainage — water should run off toward the sides
Not coarse (too little 0–2 mm). Not tight/slippery (too much water or surface material).
When routines are in place, maintenance becomes a natural part of club culture — and the court stays excellent from May to September.
