2 Keep areas weed-free by a combination of herbicide applications and hand-weeding/hoeing. Ensure that the methods used will cause a minimum of damage to adjacent planted areas. Do not allow nylon filament rotary cutters or other mechanical tools closer than 200mm to the stem of any hedge plant, carry out operations close to stems using hand tools. Maintain a minimum of 500 mm either side of the hedge grass & weed-free area around the base of the hedge.
3 Herbicide application: A foliar acting translocated or contact herbicide will be applied to emergent weeds.
4 Hand weeding: Hoe and loosen the soil throughout the planting areas, taking care to avoid disturbance of roots of planted material. Remove weeds entirely, including roots. Remove the minimum of soil and minimise disturbance to plants, bulbs and mulched surfaces. On completion, rake areas to a neat condition.
Watering
Watering is required only at planting, apply a heavy watering to the full rooting depth. If the addition of bark mulch is delayed, then apply mulch only after rain or watering. No other watering is required unless during periods of drought in establishment phase. Take into account published meteorological data on rainfall for any given period, in particular in periods of Spring drought during April, May & June. Therefore, if required, undertake a heavy watering to full rooting depth. The contractor will need to arrange for a mobile water bowser or tanker to bring the required clean water to site.
Failures
Towards end of first growing season a survey will be undertaken to assess successful uptake of planting and make recommendations for replacements. Any hedgerow trees planted that, within a period of ten years after planting, is removed, dies or becomes, in the opinion of the relevant planning authority, seriously damaged or diseased must be replaced in the first available planting season with a specimen of the same species and size as that originally planted.
6.4 Amenity Grass for Verges and Embankments (G1) 86.
The aim is to create a healthy and full lawn turf along the access road verges, the internal face of the earthworks bunding and verge adjacent to perimeter footpath around the substation.
87.
Details of the maintenance of the verges and embankments are detailed in Table 6-3: Table 6-3 Maintenance of Verges and Embankments
Verges and Embankment Maintenance Cutting
1 A low-frequency rural grass mowing regime will be adopted, with some grass verge and embankment areas allowed to grow longer, with two cuts undertaken between May and September. If required, a mowing strip of 1m along the access road verge will be cut more regularly to give the appearance of a deliberately managed and maintained edge, with two cuts per month between March and October. Grass cuttings will be removed.
2 The benefits of cutting less frequently include lower maintenance costs and improved opportunities for bio-diversity. Particularly during prolonged periods of dry weather, leaving the grass longer will shade and protect the root zones of the grasses.
3 During dry spells do not cut grass. Weed Control
Regular grass cutting will generally suppress broadleaf weeds therefore weed as necessary using spot herbicide treatment or manual removal of the following: all broad leaved weeds;
docks (Rumex spp);
injurious weed species listed in theWeeds Act 1959 andWildlife and Countryside Act 1981; Japanese knotweed (Fallopia spp); nettles (Urtica spp);
ragworts (Senecio spp); thistles (Cirsium spp); and
willowherb (Epilobium spp) Watering
