- Low light reduces photosynthesis which in turn reduces carbohydrate production and rooting.
- In low light conditions, plants naturally grow upwards in order to out compete other plants and capture more light.
- When the low light is caused by permanent shading (not caused by competing plants) then this can also cause etiolation. Etiolation causes long, stretched out growth producing weak plants.
- The causes of shading (trees/buildings) are also likely to reduce air movement therefore meaning the turf surface stays wet for longer meaning potential increase in disease occurrence.
- Turf growing in shade also has a thinner leaf cuticle which can make the plant more susceptible to disease attack.
- Where possible manage the environment to reduce the amount of shade. Encourage the turf to grow without excessive vertical growth and encourage better rooting.
- Reduce nitrogen inputs versus full sun areas
- Reduce irrigation compared to full sun areas
- Dry surface with use of penetrant wetting agent
- Aerate well to encourage good rooting and movement of surface water
- Increase carbohydrate levels in plant. Select shade tolerant grass cultivars.
