Reduce the mowing height gradually through the month until it reaches the required height.

Light rolling and a systematic but gentle raking will assist spring growth.

Worm casts should be removed and lawn edges reshaped and trimmed.

If the weather is mild towards the end of the month, apply a spring lawn fertiliser at half the recommended rate (reserve the other half for application in May). Any weed control would be a separate operation with a proprietary liquid lawn weed killer.


Thin or coarse patches of grass can be reseeded or turfed (ensure the lawn remains level).

Apply lawn fertiliser as instructed on the packet if none was applied in March. If necessary, this can be a “weed and feed” preparation.

Do not use “weed and feed” or selective weed killer on seedling grass or young turf.


Most lawns should only require mowing once a week. However, as the grass approaches its maximum growth rate, it may be necessary to increase the frequency for best results. Little and often is preferable to a more severe cut.

Dead grass or thatch should be raked out early in the month.

The other half of a March fertiliser dressing should now be applied.

An appropriate weed killer can be applied if necessary and not already done.

Occasional rolling is beneficial and done automatically if the mower is equipped with a roller.

In dry weather trim less frequently and set the mower blades a little higher.

Small amounts of grass cuttings may be left spread on the lawn to retain moisture if there has been little or no rain, but beware as this may return unwanted seeds to the soil.

If the lawn shows signs of droughts stress, it will lose its colour, springiness and texture. It should be watered early in the morning or evening; the frequency will depend on the type of soil and grass.

Weather conditions will also influence the situation but a good soaking once a week should be adequate. Over watering will encourage shallow roots and weeds.

Spiking the lawn with a fork will help water soak into dry, hard soil.

A seaweed based lawn tonic, preferably containing additional iron, will feed the lawn, but if the lawn is showing signs of wear, a summer lawn fertiliser should be applied instead or additionally.

July & August

Mowing frequency can be adjusted as growth slows.

Additional fertiliser should not be necessary but if required, a half dose of spring/summer lawn fertiliser applied in July should be sufficient.

During prolonged spells of hot, dry weather, it may be advisable to heighten the level of cut a little, otherwise action as per June.

Apply an Autumn fertiliser combined with a suitable weed killer if necessary.

Scarify to remove thatch. If the grass is thin, or needs improvement, sow a suitable seed mix ½ oz (14gms) per square yard early in the month.

If re-seeding has not been necessary, after a close mowing, any irregularities in surface levels may be corrected by spreading a top dressing of sandy topsoil or mix of 3 parts sharp sand, 1 part fine peat and 3 parts good loam. The dressing should be dragged to and fro with a lute or the back of a rake, to leave the dressing in the depressions. Application rate should be 6-9lbs per sq yd, but be sure to leave the grass laves visible.

Aerate the surface thoroughly with a garden fork or aerator.


If there are still activities to be completed from September, use the early weeks of October to finish them.

If additional areas are to be turfed, this is an excellent time to do it.

Raise the height of the cut on the mower a little when mowing.

Apply a seaweed based lawn tonic with iron.


Trim the grass only if it is still growing.

Remove fallen leaves, worm casts and other garden debris regularly.

It is too late now for seeding, but turfing will still be successful.

Remove leaves and other debris from the lawn.

Aerate when conditions permit.

Ensure the mower has been overhauled.


Continue to remove debris, including worm casts.

If the grass is getting long and untidy, trim lightly when the grass is dry, using a box mower.
