Progardes Establishment Guide

Establishment goals

1. Prepare the best seed bed possible

  • The better the soil seed contact and reduction in competition, the better the likelihood of good establishment

2. Sow when conditions are best for germination and establishment

  • Ideally, sow with a good moisture profile or/and when there is a high chance of effective rainfall and follow-up rain

3. Provide right soil conditions and nutrition for optimum growth

  • Clay rich soils with a neutral to slightly alkaline pH are ideal. Ensure soil is tested to provide appropriate environment for growth

4. Minimise competition from weeds and dominant grasses

  • Use cultivation, fire, grazing, and/ or selective herbicides to minimise competition

5. Control Pests

  • Minimise damage of young seedlings from pests where possible

6. Let Progardes fully flower and seed in the first season of growth

  • Exclude grazing until first flower and seeding has occurred (unless essential for control of excessive grass competition)


Progardes® Desmanthus planting rate recommendations and further considerations

The following tables provide guidelines on the minimum level of seed to be planted per hectare for a number of different paddock circumstances. Generally, methods to the top of the table will give a greater likelihood of a rapid and successful establishment. However, Progardes’ hard seeded content can also allow for delayed germination and subsequent establishment success over time.

Specific Inoculant (CB3126) is available and should be used wherever establishment conditions are likely to maintain inoculant viability.

Progardes® Desmanthus is a very fine seed (up to 300,000 seeds/kg) and care should be taken not to plant deeper than 5mm when using drilling equipment.

Level of soil disturbance Soil moisture conditions Competitive Grass or Weed seed level Planting method Planting rate (grass – Progardes pasture) Planting rate (pure Progardes sward)
Full Preparation

(E.g. cultivating paddock or strips to Progardes® Desmanthus)

Full cultivation with fine seedbed Full soil moisture profile and likelihood of follow-up rain Little to no weed or grass competition and/or pre-emergent herbicide used Precision planted, airseeder or broadcast and light harrow. Rolling ideal 2 Kg/Ha 4 Kg/Ha
Partial Preparation

(Flat county previously cultivated or using direct drills)

Same as above but on difficult soils with coarse tilth. Direct drilled with either boot or discs Full soil moisture profile and likelihood of follow-up rain Little to no weed or grass competition and/or pre-emergent herbicide/ glysophate Broadcast via aerial or spreader, airseeder, or direct drilled to max depth 5mm. rolling beneficial 3 – 4 Kg/Ha Not recommended
Limited Preparation

(Burnt, heavily grazed or lightly disturbed seedbeds)

Rough cloddy seedbeds. Eg heavy offsetting, blade plough, stick raked

or, burnt, heavily grazed native pastures

limited soil moisture profile and likelihood of follow-up rain Buffel grass well knocked back  or limited weed seed or little to moderate native pasture Aerial or broadcast prior to likely rain event 3-4 Kg/Ha Not recommended
Faecal seeding Nil Suited to semi-arid regions More suited to native grass Include hard seed into supplement 1 – 2% of supplement Not applicable
