The site is made ready for sowing, a technique of shuddering, using the Hymac bucket to roughen the soil is employed. Do not allow contractors to smooth or compact the final 50-150mm of soil.

Prior to sowing, Design By Nature use lime or yellow marker paint to lay out the areas for sowing different floras and mixtures. We sow the wildflowers making slight changes according to the local site specific conditions and the landscape contractor sows the special grass mix according to instructions. The wildflower seed and grasses are raked in at the same time. 

CASE STUDY: The upper section on the Claremorris Bypass was sown with Salix (Willow) Cutting in mid May (very late for cuttings) due to the non availability of trees because of an outbreak of Foot and Mouth Disease in 2001. By the end of May the cuttings had struck, but we are not very hopeful, as it was so late, to compensate we sowed 9 cuttings to get one good shrub ( 3 cuttings 250mm apart in groups 75 cm apart) This is the first time this planting strategy has ever been used. A unique DBN solution.

We even tried and tested cuttings of Elderberry (Sambucus nigra), these suffered in the drought that followed but elder grows from cuttings and we are hopeful.

Note the irregular layout to reflect the surrounding countryside, no straight lines on a DBN roadside planting, just what the west of Ireland deserves. The left hand photograph shows poured concrete around the base of a lamppost, this was sown extra heavily with species that require very little soil. I hope it grows to cover a difficult spot.

The roadside engineer Ann Sweeny and landscape designer Shane O'Neill took a big risk, but they had little choice as the roadside cuttings were slipping due to springs in the soil. Our task is to establish flora, any flora and fast.

We choose clump forming grasses, sown at very low rates for high root zone activity, we mixed in our specialist mixtures of wildflowers and Salix.

Hand sowing and raking was chosen instead of hydraseeding, this gave us a chance to put the right species in the right place.

Note: The right hand photo shows stored top soil for spreading on roadsides, this soil requires special attention.  Claremorris Update
