Sowing Instructions

Prepare the Ground

  • Wetland & Pond Edge Wildflower Seed Mix performs best in low nutrient soils, which haven’t been heavily fertilised in the past.
  • For best results sow into bare soil after clearing all existing plants and weeds from the area.
  • Cultivate the ground to a depth of 10cm to relieve compaction and create a fine
  • level tilth.
  • Finish the seedbed by treading or lightly rolling the area, so that it is firm enough to stand on without leaving indentations.
  • Where weeds have been prevalent, allow a flush of weeds to germinate and then remove these before sowing.
  • In areas of high fertility, it may be necessary to remove the topsoil and sow into the subsoil.


Wetland & Pond Edge Wildflower Seed Mix can be used to overseed into existing grassland, provided the sward comprises only fine leaved grasses and does not include ryegrass, agricultural species or weeds.

Cut the grass as short as possible and thoroughly scarify or rake the ground to remove any thatch, moss and other debris from the area.

Sowing
Wetland & Pond Edge Wildflower Seed Mix should be sown between March and November. Spring and autumn provide ideal conditions as moisture and warmth are in good supply. If overseeding into grass, it is best to sow during autumn when grass growth has slowed down.

Sow wildflower seeds at the recommended sowing rate of 3g/sqm.

Ideally, mix the wildflower seeds with an inert carrier such as sharp sand, at a ratio of four parts sand to one part seed by weight.

Regularly mix the seed when sowing, as seeds will naturally separate due to
variations in size and weight.

Once sown, ensure good ‘seed to soil’ contact by lightly raking to a depth of 0.5cm
or rolling the area. When overseeding this encourages the seeds to fall down to the ground underneath.

It is also possible to broadcast, drill or hydroseed this mixture for larger or hard to
reach areas. However, broadcast spreading throws heavier seeds further so this
may impact the distribution and when drilling, the seed must not be buried deeper
than 0.7cm.


Sowing Rate
The sowing rate of 3g/sqm is designed to produce optimum results. Reducing
the sowing rate is likely to result in invasion from weed species. Increasing the
sowing rate generally leads to reduced diversity as the more aggressive species will outcompete slower growing plants.

This rate also applies when overseeding into grassland as many seeds may fail to
germinate due to the increased competition from the existing grasses, and some
seeds not reaching the soil surface.

Maintenance

First Year
This mix contains perennial species, which can be slow to establish and are unlikely to flower in the first year.

During the first year remove any weeds which grow before they run to seed, either by topping, mowing or by hand for smaller areas. Weed growth is common due to the action of disturbing the ground (rather than being caused by contaminated seed mixtures). The area can be cut once the flowers have died back in the autumn.

We recommend leaving the area undisturbed for as long as possible, ideally until February / March (before the first spring growth). The dead flowers and stems provide a diverse environment which is a haven for wildlife through the winter
months. In particular, it provides habitat for butterflies such as the Red Admiral and the Clouded Yellow which remain in their chrysalis during the winter months.
Cut the area down to around 10cm using a scythe, strimmer or mower, leaving the cuttings for up to a week before removing.


This will allow them to dry and shed seeds back into the soil.


Second Year
After twelve months the sward should be well established and requires little additional maintenance. Simply follow the same annual cut pattern (either in spring or autumn depending on your preference).

As an ongoing process, observe and remove any weeds which invade the area.
Over time, some species within the mixture may become more dominant due to environmental factors and natural selection. To encourage diversity, simply reduce the number of dominant plants in order to restore the balance.


Overseeding
If overseeding into grassland, we recommend incorporating at least two 10cm cuts each year; at the beginning of March and November. This reduces the grass canopy, allowing light and air to reach the wildflowers and encourage growth.

Where aggressive grasses are dominating, it may be necessary to employ a more regular cutting regime to ensure the wildflowers are not smothered.
