Before going out to purchase wildflower seeds, you need to make a measurement of the proposed lawn area. Lawns come in a variety of shapes and sizes, so measuring to the nearest millimetre is not required, with around 10% accuracy being fine for seeding.
10% should be added for mismeasuring, 10% for seeds eaten by the birds and an additional 10% for filling in any thin spots around a month after sowing. This equates to approximately a third more seed than is required for your measured area. Any excess can be used in the future for lawn repairs, so will not be wasted.
Over-seeding your lawn after scarifying or raking
You should always overseed after scarifying to help the lawn return to a dense turf as quickly as possible. It is also a perfect time to introduce new types of grasses to your lawn.
Sowing rate for Annuals
Annuals are usually sown at 5g per m2.
| Area in m2 | Seed Required | |
|---|---|---|
| 1 m2 | = | 5g |
| 5 m2 | = | 25g |
| 10 m2 | = | 50g |
| 50 m2 | = | 250g |
| 100 m2 | = | 500g |
| 200 m2 | = | 1kg |
| 500 m2 | = | 2.5kg |
| 1000 m2 | = | 5kg |
| 10000 m2 | = | 50kg |
Please note: 1 Acre is approx 4,000 m2; 10,000 m2 = 1 Hectare; 1 Hectare = 2.3 Acres
Sowing rate for Biennials and pure Perennials
Usually sown at 1g per m2
| Area in m2 | Seed Required | |
|---|---|---|
| 1 m2 | = | 1g |
| 5 m2 | = | 5g |
| 10 m2 | = | 10g |
| 50 m2 | = | 50g |
| 100 m2 | = | 100g |
| 500 m2 | = | 500g |
| 1000 m2 | = | 1kg |
Please note: 1 Acre is approx 4,000 m2; 10,000 m2 = 1 Hectare; 1 Hectare = 2.3 Acres
For large-scale meadow creation projects using seed drilling techniques you can sow at rates as low as 0.5g/ m2 or less.
