SA growers: Ludwig's - & Duncan's Roses
  • Petunia Supertunia's

    Petunias are one of the most popular bedding flowers. They have wide trumpet shaped flowers and branching foliage that is hairy and somewhat sticky. They are prolific bloomers, although some forms require dead-heading to keep them going. Most varieties will bloom throughout the summer, except in extreme heat. You can now find petunias in just about every colour.
  • Tip of the Month

    Turn off the tap when you brush your teeth – this can save 6 litres of water per minute. Fix leaking taps. Place a cistern displacement device in your toilet cistern to reduce the volume of water used in each flush. You can get one of these from your water provider. Shower rather than bath and when you shower, take a shorter shower. Use energy efficient washing machines.

Hybrid Agapanthus are not that new with many varieties released over the past few years. What makes Zambezi exciting is that it is the first tall flowering and large growing variegated on. The tall flowers are a violet blue and the plant flowers right through summer. The very yellow edged leaves make quite a show and contrast well with other plants to make a statement even when the plant has no flowers. Billed as the best agapanthus ever plant them in a container as a specimen plant or in the garden where they get at least half day sun.



  • Rainwater-harvesting ref1Rainwater harvesting is the collection, storage and distribution of rainwater and the perfect storage facility for rainwater is a water tank.
  • Rainwater can essentially be used anywhere you use tap water.
  • The idea of using drinking water to flush toilets and water lawns is wasteful and irresponsible, especially in light of the population growth and water shortages across the country.
  • Rainwater harvesting greens your home lessens your environmental footprint. Rainwater is an absolutely FREE source of water.
  • You will reduce flooding and erosion caused by storm water run off


  • 1mm of rain allows you to harvest 1L of water per m2 of roof area – just allow for a 15% wastage factor.
  • Make sure that your gutters are installed to direct rainwater to rain water tanks.
  • An annual rainfall of 500 mm on a roof surface of 50 m² amounts to 25 000L of potential safe drinking water that can be preserved (40L per day for 625 days) or wasted! In South Africa, the water allocation per day per person is 25L


  • Your water tank filled with harvested rainwater provides water security when the municipal water is cut off for any reason whatsoever. If your tank is connected to the water mains, it will act as a storage buffer and depending on the size tank installed you will have running water for up to 48 hours.
  • A water tank gives you total control over your water supply
  • The process uses simple technologies that are inexpensive and easy to maintain
  • A rainwater harvesting system can be easily retrofitted to an existing structure or built during new home construction.
  • JoJo Tanks are available in a variety of sizes from 260L to 20 000L. Simply select the size most suited to your requirements and start harvesting water for security!


  • Make sure that the tank is completely sealed (naturally you need to provide for an inlet pipe or gutter) to prevent evaporation and mosquitoes from breeding
  • Make sure that the tank has a sieve to catch leaves and twigs that flow down the gutters

jojoowlhouseThe JoJo owl box can be installed by:

1. Attaching it to a wall
2. Placing it on a pole (pole base plate included)
3. Affixing it onto a flat surface by cutting off the pole base plate and levelling the bottom surface.

Guidelines to encourage raptors and owls in assisting with rodent management:

1. Erect perches around and in the fields to enable birds to catch rodents that venture into the crop fields.
2. It is advisable to have a cleared area of at least 2m wide around the field with perches erected within the area.
3. Perches for raptors should be made of 3m x 50mm gum or poplar poles and be planted to have a height of 2.4m above the ground surface.
4. Perches for owls can be shorter – 1.6m x 30mm gum or poplar poles that are planted to a height of 1.4m.
5. For both perches long sisal inflorescence stems may also be used to save on costs. Long and short poles should be planted at the outskirts of the tilled zone at 50m intervals.
6. No cross arms should be erected on perches as previous experience indicates that the birds prefer straight poles. Untreated wood is the best to use.
7. To attract owls and diurnal raptors to the perches, it is advisable to scatter a few handfuls of crushed grain around the perches the late afternoon. Gerbils will soon discover the food and lure owls and raptors to the perches.
8. It is advisable to removed barbed wire from fences where perches are erected in close proximity to fences as owls are often trapped by barbs when they try and perch on fences, This is particularly true for marsh owls, barn owls and spotted eagle-owls.
9. Should crop field fences have smooth wire the fence post could be modified to suit as owl and raptor perches. No rodenticides should be applied while raptor perches are up. Should rodenticides become necessary, the perches should be taken down.
10. Rodent food supply. It may be worthwhile to put some grain out around the raptor perches outside the perimeter fence to habituate rodents to the immediate areas around the perches.
