FAQ

What is hydroseeding?

Seed and fertiliser are uniformly mixed and agitated in solution with water and sprayed by monitor or hand held hoses onto the soil surface.

What is hydromulch?

It is a combination of seed, fertiliser and cellulose mulch uniformly mixed and agitated in solution with water. The slurry is sprayed by monitor or hand held hoses directly onto the soil surface.

What are the advantages of hydromulching?

Uniform application, increased water retention, seed at correct depth in soil/mulch ratio, decreases soil losses due to wind or run off, reduces predation by birds or insects, access by hose in inaccessible areas, may include binder to further enhance stabilising properties, custom seed to suit site, native grass, tree or shrubs seed can be used.

What is Straw Mulching?

This is a two stage process –

Hydroseeding (As outlined above)
Straw mulching – Bales of straw are fed into a “Straw Mulcher”. The straw is flailed, spun through a turbine and blown at high velocity through a barrel to spread evenly across the hydroseeded surface.

What are the advantages of Straw Mulching?

Suitable for harsher conditions, impoverished soil, no after care, provides a suitable microclimate for seed to germinate, surface water flow slowed by the straw matrix, seed not blown away by the wind, mulch layer breaks down to add organic material to soil and bird and insect predation is reduced.

Where is it used?

Hydromulching application may range from landscape applications, both commercial and domestic, playing fields to golf tees and greens as well as harsher areas due to the ease of applying the material by extension hoses.

What do I have to do to prepare for hydromulching?

Remove weeds by spraying with non residual herbicide such as Round Up or similar.
Lightly cultivate the soil by rotary hoeing or by hand digging. Add Gypsum at a rate 2kg per m² and hoe again if the topsoil is heavy. If possible test soil for pH and salts.
Add more topsoil if necessary, a minimum depth of 50mm.
Order your hydroseed/hydromulch from BWD.
Rake the soil level ready for hydroseeding.

What seed mix can I use?

BWD offer a range of seed mixes from Rye grass, Fescue, kikuyu or couch.

How is it priced?

Hydromulching is priced per m² of land. For example

Square = Length X Width Rectangle = Length X Width
Triangle = Base X Height X 0.5
Circle = 3.14 x Radius x Radius

Pricing will vary depending on the size of the project.

How long does the seed take to germinate?

Approximately 2-3 weeks in favourable conditions. For example, Time of year the seed is sown, climate, temperature and water availability.

How do I care for my new lawn?

Commence watering immediately. Do not allow the hydroseed to dry off for long periods of time. KEEP IT MOIST.
When lawn is 75-100mm high cut with a rotary mower. Remove no more than 1/3 ot the grass height at any one time.
When turf is approximately 10 weeks old feed with a turf builder tye fertiliser at the rate of 2.5kg/100m².
Regular maintenance including fertilising, weeding and topdressing. Insure adequate irrigation practises.
