How do I fix dog urine patches on my lawn?

Dog urine burns grass due to high nitrogen concentration. To fix existing patches: rake out the dead grass, water the area well to dilute remaining salts, apply a thin layer of topsoil, overseed with fresh grass seed, and keep moist until established. To prevent new patches: water the area immediately after your dog urinates, or train them to use a designated area.

What is the ugly light green grass in my lawn?

Light green clumpy grass is often a weed grass like POA annua (annual meadow grass) or Yorkshire fog. These grasses grow faster and look different to your lawn grass. Unfortunately, there's no selective herbicide to kill them without killing your lawn. The best approach is to maintain a thick, healthy lawn that outcompetes them, and overseed with quality grass seed to gradually replace them.

Why is my lawn bumpy?

Bumpy lawns are usually caused by: earthworm activity (small mounds), uneven settling of soil over time, poor initial preparation when the lawn was laid, heavy foot traffic creating compaction in some areas, or animals digging. Identifying the cause helps determine the best fix - regular topdressing helps most bumpy lawns over time.

Q: Why is my grass turning yellow?

Yellow grass is usually caused by nutrient deficiency (especially nitrogen), overwatering, underwatering, compacted soil, or disease. The most common cause is lack of nitrogen - a proper feeding programme will usually restore colour within 2-3 weeks. Check your watering habits and soil drainage if feeding doesn't help.

Q: How do I level a bumpy lawn?

For small bumps and dips: apply a thin layer (no more than 1cm) of topsoil or lawn levelling mix, work it into low spots with a rake, and let the grass grow through. Repeat every few weeks until level. For severe unevenness: cut the turf, remove or add soil underneath, replace the turf, and water well. The best time to level is during active growth in spring or autumn.
