The South African Landscaper's Institute (SALI) is joining the battle to fight the invasive polyphagous shot hole borer (PSHB) beetle that poses a serious threat to both exotic and indigenous trees across South Africa.

The beetle is known to invade the host tree and bore holes in the branches. If undetected, it can destroy a tree within a relatively short period of time.

Adult beetles invade a variety of tree species and dig tunnels to lay eggs. The PSHB beetles then transport a fungus which attacks the tree’s vascular tissue, causing a disease called fusarium dieback (FD).

FD in turn interrupts the supply of water and nutrients to the tree. It’s known that PSHB attacks more than 300 tree species countrywide of which more than 130 of these species are susceptible to FD.

The PSHB beetle attacks a variety of tree species which include oak, most willows, plane trees, avocado, some acacias and most maples.

Reports quoting academic research show that, in other parts of the country, more than 10 000 trees have been lost which could have an adverse effect on the ecosystem and take years to replace.

Metropolitan areas such as Johannesburg and Durban as well as Pietermaritzburg, George and Knysna have lost thousands of trees.

How can you help?

    1.  Contact a SALI landscaper to advise if you have a PSHB invasion in the trees on your property.

    2.  Distribute the TWO education posters on the PSHB beetles prepared by SALI.

The Johannesburg International Flower Show (30 October - 3 November 2019) at Waterfall City has announced their collaboration with a host of South Africa’s leading industry experts who will play an integral role in creating a floral wonderland.

Preparations for the Johannesburg International Flower Show have begun! Civil engineers and heavy machinery have arrived on site at the Waterfall City show site, just below the Mall of Africa in Midrand, Johannesburg. Their aim is to prepare the grounds for the lavish and exotic garden displays for the show that launches on 30 October, 2019

On 9 April, 2019, the City of Cape Town confirmed that the invasive polyphagous shot hole borer  (PSHB) beetle was positively identified in Somerset West.

The PSBH infestation was discovered in Oldenland Road, Somerset West by passionate gardeners and environmentalists who noted that a London plane tree in their garden was ailing and exhibited signs of a PSHB beetle invasion.

  • In November 2013, the owners started rejuvenating this Old World Garden as they wanted to bring it back to its former glory.
  • The approach was to create light by pruning the old trees enough to create filtered sun as many of the beds were in deep shade.
  • Once that had been achieved the beds needed trenching and feeding with tonnes of compost and organic fertilizer.
  • Here is a mix of roses, Buddleja 'Buzz', penstemons, mixed salvia and cascading convolvulus interspersed with annuals for the season.
  • A touch of old fashioned herbs like achillea have worked to bring seasonal colour.
  • The shade gardens have a mix of plectranthus, impatiens, arums,and hydrangeas. Forest bell bush (Mackaya bella) is often used in the shade beds to close back ground walls.
  • The edges of the beds gravel driveways have been defined by the natural rock boarders, so typical of Westcliff.

SALI landscapers are experts in wetland-scaping - the creation of ecologically-friendly wetlands landscaped by professionals. 

World Wetlands Day (2 February) is a good time to think about the importance of creating wetlands around your home or business. 

The theme for the 2019 World Wetlands Day on February 2 is ‘Wetlands: The key to coping with climate change'. 

In 1971 the environmental value of wetlands was finally recognised by governments throughout the world. On February 2 of that year the Ramsar Convention on Wetlands was signed. The convention is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.

It is so named as it took place in the Iranian city of Ramsar on the shores of the Caspian Sea. The date of the signing, February 2, was designated as World Wetlands Day. South Africa is a signatory to the Ramsar Convention. 

What are the benefits of wetlands? Wetlands are like stepping stones and form vital links in the chain of water supply across semi-arid South Africa.

Natural sponges

Wetlands act as natural sponges that hold water during rainy seasons and reduce the danger of floods and soil erosion.

  • They release water slowly during drought periods.
  • They purify the water that passes through them.
  • They provide food, housing materials and traditional medicines for local communities.
  • Wetlands are also extremely rich in biodiversity and many species of plants, animals, birds and insects cannot survive without wetlands.

Wetlands are under siege, as a result It is estimated that 50% of South Africa’s wetlands have been destroyed through development, water pollution and general human growth. As a result, species dependent on wetlands are declining faster than those reliant on other ecosystems.

WWD SpongePS

Develop a wetland

South African landscapers are at the forefront of wetland-scaping. When large tracts of land have been approved for development as housing estates, golf estates and business parks, landscapers identify mini wetland areas and incorporate them into their plans.

Some landscapers identify low lying areas and develop them into attractive wetland areas with appropriate plants which in turn provide an ecosystem for endangered wildlife. 

Award winning wetlands created by SALI professionals

Flufftail celebrated on World Wetlands Day

Do you have a wetland?  Would a wetland benefit your landscape?  Do you need a SALI landscaper to install a wetland on your property?

World Wetlands Day (2 February) is a great time to remember the importance of wetlands and water birds in the landscape. 

One of the biggest events during World Wetland Week will be the 5th Annual Flufftail Festival which takes place at the Johannesburg Zoo & National Zoological Garden.

What is a Flufftail?

The White-winged Flufftail is a critically endangered wetland bird discovered in the moist, high altitude Middelpunt Wetland in the Greater Lakenvlei Protected Environment at Dullstroom, Mpumalanga in 1981.

For decades Birdlife experts believed the secretive white-winged flufftail, one of the world’s rarest birds, bred in just one place: the moist high-altitude Berga Wetland in Ethiopia. Then it was found in South Africa.

Alarming population estimates suggest there are around 250 of these birds globally, and only around 50 remaining in South Africa. As a wetland ground nesting species, the critically endangered Flufftail has become a poster pin up for the need to protect, nuture and extend wetland habitats across South Africa.

Honoring wetland birds

"We support the 2019 Flufftail Festival as an educational initiative which aims to create awareness on wetlands, water and water birds", says Norah de Wet, National Chairperson of SALI.

World Wetlands Day (2 February) and World Water Day (22 March) are ideal days to educate the public on wetlands, water and water birds.

The importance of wetlands, how they function and the role they in our society will be unpacked, particularly with regards to reducing the impacts of climate change.

The extreme weather conditions being experienced throughout the country is a reminder for constant education on the importance of water conservation and there is much to be learned at this year’s event.

Wetlands and education 

As part of the Flufftail Festival, approximately 500 Grade 6 learners will be exposed to the selected zoo’s on 8 February and 1 March while working through educational activities on water, wetlands and water birds.

In addition, approximately 400 community members will have an opportunity to explore the Johannesburg Zoo on 09 February and participate in the activities.

Members of the public will receive discounted entry fees on 2 & 3 March at the National Zoological Garden in Pretoria.

The World Wetlands Day - 2019 Flufftail Festival is hosted by Rand Water (Water Wise) together with BirdLife South Africa, Toyota, Gauteng Department of Agricultural and Rural Development (GDARD), Joburg City Parks and Zoo and the South African National Botanical Institute (SANBI).

Beat the heat with lawn says SALI turf expert

With soaring summer temperatures experienced across the country, plants are taking strain and your lawn is no exception.

If you are contemplating removing lawn and replacing it with hard landscaping or artificial lawn, don’t be too hasty.

Despite a move towards low-maintenance and more water wise gardens, lawns do still have a role to play in city gardens. “Natural turf grass controls soil erosion as the root system grows into the soil and can be used to hold the soil on a gentle slope,” said Fanus Cloete, CEO at Evergreen Turf.

“Lawn also reduces heat when compared with hard rock surfaces, asphalt and concrete.”

Cloete explained that on a hot day, the temperature on grass may be around 17 or 18 degrees Celsius, compared to 55 degrees Celcius on asphalt.

“Grass also plays a role in capturing dust, smoke particles and other pollutants so air quality is improved,” said Cloete.

Lawns provide a place for entertainment in the garden and an area for children and pets to play. It compliments a garden’s design and, like all plants, it absorbs carbon dioxide and releases oxygen.

Lawn types

Buffalo grass (Stenotaphrum secundatum) is recommended for the winter rainfall Western Cape region and well as indigenous Cynodon species that are able to withstand periods of drought. Gulf Green, a Cynodon variety, is bright green in colour and suitable for a wide range of soil types.

The popular kikuyu is a warm season grass that requires at least six hours of sunlight per day to thrive. LM is tolerant of shade but not of drought and cold conditions. Although cool season grasses, like Shade-Over and Evergreen Gold, are green throughout the year, they do require more water.

Summer lawn care

Points to consider for a healthy lawn in summer.

 Argus Lawns 26 January 600x400PS

 

Mowing regime

Fanus Cloete says that it’s important not to mow your lawn too short in hot weather. “Leave it a little taller so there is enough leaf area for the plant to transpirate and cool down,” he added.

Aim for a mowing height of 20 to 25mm for warm season grasses and Cynodon species and 30mm for cool season lawns in sun and 50mm in the shade.

If your lawn looks whitish and takes a few days to bounce back after mowing, you are likely cutting it too short and exposing the softer parts of the leaf blade to the sun. Also check mower blades. A brown or whitish look may be the result of blunt blades.

When to water

Water thoroughly once per week rather than a few minutes every day. This encourages deep rooting which helps the grass cope better during periods of limited rainfall. Water in the early morning or after the sun goes down.

“Watch the colour of the lawn,” advised Cloete. “Most varieties will turn pale, brown or bluish when water is needed.” Don’t over-water your lawn. If you have an irrigation system, turn it off during rainy periods.

Under Cape Town’s current Level 3 water restrictions, municipal water (using a bucket or watering can only) may be used for watering plants before 9am and after 6pm on Tuesdays, Thursdays and Saturdays, for one hour per day per property. No hosepipes and sprinklers may be used. Opt for harvested rain water to irrigate your lawn.

“Grey water reuse is extremely helpful in maintaining a healthy lawn during times of drought and low rainfall,” said Mark Joubert of GardenResQ. “Grey water contains micro-organisms as well as many nutrients, which is then supplied to the lawn and plants that you are watering. Grass watered with grey water is often a very vibrant and healthy green.”

Never use water from sinks or dishwashers and keep grey water on your porpery. If you use laundry water, change to a detergent that is biodegradable. Never store grey water.

When to fertilise

Fertilisers are important to ensure that your lawn has good root system. “The deeper the root system, the healthier the lawn is and the deeper the roots will go to retrieve moisture in the soil,” explained Fanus Cloete.

Lawns should be fertilised at intervals of between 40 and 60 days. Whether you choose an organic or inorganic fertiliser is a personal choice. Inorganic products are available immediately to the plant, while organic products take time to break down in the soil.

For a chemical fertiliser, Cloete suggests a 5:1:5 fertiliser which can be use twice per year in September and February and a general LAN fertiliser during the interim periods.

Remove weeds

Weeds look unsightly and if left unchecked in the lawn, they may choke out turf. Use an appropriate broadleaf herbicide to control them.

Watch for problems

Keep an eye out for lawn caterpillar, especially in January and February. They live below the soil during the day and come out at night to feed on grass, leaving behind dead brown patches.

To confirm lawn caterpillar, place a damp towel on the lawn overnight and check under it in the morning. Once confirmed, treat with an appropriate biological insecticide so birds can safely eat the dead caterpillars.

Dollar spot is a fungal disease more prevalent when the weather is hot, with periods of rain. Dead patches are straw-coloured and round in shape, about 25 to 50mm in diameter.
Brown patch is lawn disease also caused by a fungus and is more common during hot, humid weather. Both problems can be treated with an appropriate fungicide.
