How Much Wildflower Seed Do I Need?

 

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.
