| Shaded lawns |

Grass that does not receive enough sunlight will often deteriorate, becoming sparse or of poor quality
The first consideration should be; removing the cause of the shade e.g. if the shade is caused by trees, then thin them out by pollarding them then keep them under control, or better still remove the trees.
Grass / Turf will rarely do well under trees, it will always be competing for water and nutrients, plus drips from the tree canopy can damage the lawn.
If ‘removal’ is an option ensure that there is not a TPO (Tree preservation order) on the tree/s.
If this not an option, then the type of grass will have to be considered.
Most grass / turf require four to six hours of full sun each day, to allow photosynthesis to occur.
If starting from new or renovating; choose a shade-tolerant seed mix.
These are quite often a mix of creeping fescue to bind the lawn together, meadow grass for hard wearing and drought tolerance, chewing fescue which will tolerates close mowing, and bentgrass which gives the lawn a tighter appearance and provides good winter greeness.
But always remember; even shade tolerant grasses need some light to survive.
If renovating; over-seed the lawn in early September Week 35>.
However, if you find that the soil is compacted, or of low fertility and heavily infested with moss it may be better to replace it, or consider doing away with the lawn altogether, and replacing it with materials such as gravel, timber or concrete decking.
Cultural instructions;
Mow less often, keep the mower blades relatively high, say; 50-75mm (2”-3”) high and always lift the clippings.
When watering remember you will be watering the trees at the same time so it is best to water heavily at infrequent intervals, to encourage tree roots to go deeper for their moisture needs.
You may find that moss will tend to out-compete the grass, so give the lawn an application of ‘Autumn Feed and Weed with added moss killer’ around Week 35-40, and a ‘Spring feed & Weed’ around Week 15-20 the following year.
Prior to applying the ‘spring’ feed scarify the lawn with a lawn rake or mechanical scarifier to remove any thatch.
Shade cast by buildings, has been left down to the individual to resolve, perhaps he/she could consider alternative ground cover
