Wynboer Tips for April
PLANNING
- Do a thorough evaluation of the viability of each block and reevaluate your long term planning with regard to uprootings and plantings.
- Obtain advice on establishment in collaboration with soil, viticulturist and winemaker.
- Confirm vine order for 2008 and order vines for 2009 from your nursery.
- Update records of each vineyard block, e.g. productions, grape analyses, vigour, irrigation schedules, etc.
- Soil analyses of each block should be done every 3 years.
- Evaluate the actual wine goal compared to the intended wine goal per block.
- Check whether cultivar planning is still in line with cellar/market demands.
VINEYARD PROGRAMME
Cultivation
- Ensure that phosphate levels in the topsoil are correct.
- Weed control of perennial weeds with spot spraying.
- Prepare a shallow seed bed for cover crop and ghrop in seed after sowing.
Post-harvest fertilisation
- Apply N-fertiliser according to vigour and the other elements according to soil analyses.
Post-harvest irrigation
- Monitor soil moisture conditions and irrigate where necessary. Remember that vines with a large canopy still have moderate water consumption.
Disease and pest control
- Post-harvest spraying programme is necessary for the retention of leaves where oidium, downy mildew and erinose infections occur.
- It’s a good time for nematode control – make sure the ‘bankies’ are free of any weeds before treatment.
- Mark mealybug infested vines for control in winter.
Uprooting of vineyards
- Take out as many old roots as possible, remove all plant material from the soil and incinerate.
General maintenance and repair
- Good time for general maintenance and repair of infrastructure (buildings, roads, vehicles and implements).
FINANCIAL

- Viability, cost and profitability analyses.
