Patches in lawns can appear for a number of reasons, and when they do, it is always advisable to repair them. Re-seeding, or turfing bare patches will prevent weeds germinating in the patches, and of course, it looks much better.

Lawns that have developed discrete areas of poor growth, perhaps from physical damage or wear and tear, should be repaired.
Lawns that are generally poor, weedy, or sparse will benefit from a programme of thorough lawn maintenance. If the lawn is really bad, then total re-laying or re-seeding may be necessary.

Lawns are best repaired in spring or autumn, when the weather is damp and cool, as the lawn is most likely to recover well in these conditions.
Better results may be achieved by pre-germinating the seed before sowing it. Add the seed to some moist compost in a bucket and cover with clingfilm. Place somewhere warm – no higher than 15°C (60°F). After three days, check the seed for signs of germination. If none is seen, check daily thereafter. Once you see small white roots developing, sow the mixture as above.
Sometimes, repaired patches appear a different colour from the existing turf. Using turf from elsewhere in the garden (rather than new turf) to repair your lawn may avoid this problem. Otherwise, try to buy seed or turf from the same supplier as before, and request the same product as bought previously.
