Live Plants and Turf To Be Used In Playground Fall Zones Again

Live plants and turf were not allowed to be used in fall zones in playgrounds until recently. Through new testing, certain live plants and turf  have shown that they meet fall zone requirements of the Australian Standard AS/NZ4422:1996.

Avoid compacted ground like this in playgrounds by using Living Soft Fall™

Plants that were grown in soft fall mulch had a min: Critical Fall Height of 3.4 meters and turf that was grown in Living Soft Fall had a critical fall height of 4 metres, which is far superior to industry standards, and requirements of the manufacturers of playground equipment.

Our children’s safety in playgrounds is of the utmost importance and has lead to high regulation of surrounding surfaces adjacent to playground equipment.

Up to this point in time, the only ones who have bothered to undertake the expensive testing to confirm whether those surfaces meet fall zone requirements has been non-green life technologies.

Let’s look at swings for example, for swings this has often meant that a surface must be safe for children to fall 2.2m.

Critical Fall Height reports (the results from recent research) prove that certain green life is safe and complies with the Australian Standard, which now allows green life to be used in playground surfacing.

The use of plants in playground surfacing has won a KidSafe award for Innovative Design Elements. Before this research the only products that met the standards were mulch, artificial turf, and an array of rubber type products.

Landscape Architects and Designers have really embraced the 202020 vision, which is: To Increase Green Space by 20% by 2020. Now that live plants and turf are allowed to be used in in play grounds again they have another tool to increase the percentage of green life in the landscape.

The obvious advantages of increased green life is the cooling of our cities, increased oxygen production, and the increase in health and wellbeing of people.

Green infrastructure enhances the healthiness, liveability and sustainability of urban environments.

There have been many studies around the world that confirm the benefits to humans of being in touch with nature, so  why have our children in playgrounds been ignored until now? …read more

How Hot Do Common Landscape Surfaces Get In Summer?

How Hot Do Common Landscape Surfaces Get In Summer?

By Todd Layt

landscape surfaces in summer

Over the last couple of years we took the temperatures of many landscape surfaces on 40 degree days. You might find the results we got surprising. We discovered there was a great deal of variation in temperature between different surfaces. For example, from grass to gravel the temperature varied by 32 degrees. The findings from this important research could help contractors and designers create cooler landscapes.

Some hard surfaces were a lot cooler than others. Selecting the right products can greatly reduce the surrounding temperature of your backyard entertaining area. With the spreading fear about the possible temperature rises, isn’t it time to consider using cooler landscape alternatives?

It’s not surprising that the coolest temperature taken was from the surface water of a large pond, which was exactly 40 degrees, the same as the air temperature. The next coolest surface in full sun was the green grass on a sports field, which measured 45.65°. Dry grass on the same field was 51.5°.

Green grass growing near gravel was found to be 52.15°, whilst dry grass next to gravel was surprisingly 62.2°. Dry grass further away from the gravel was cooler. Shaded turf near concrete was 47.2° whilst concrete in shade was 49.8°. Gravel in full sun was 77.78° and grey concrete on a tennis court reached an amazing 78.27°, with concrete surfaces around a house in full sun 74.75°. Fake grass did not fair much better reaching 66.95°.

So the first trend that can be seen is that grass in full sun is much cooler than concrete and gravel, but so is shaded concrete. The shade of a tree reduced the temperature of the concrete by 25°. Lomandra Tanika growing in gravel that was 77.78 degrees just a few metres away cooled the gravel that was right next to it down to 53.9 degrees Celsius.

It’s amazing the plants can even survive in…read more

 

 

 

 

 

 

 

Pruning Strappy Leaf Plants – Part 2

Pruning Strappy Leaf Plants – Part 2

Even with this selection of extremely low maintenance plants, it’s inevitable that some pruning will be needed. These tips give some often eye catching pruning techniques that will keep your landscape from looking hacked at.

Pruning Strappy Leaf Plants

BABY BLISS® Dianella revoluta ‘DTN03’ PBR

An excellent garden or mass planting choice for low blue foliage. Works well all over Australia, but avoid using in depressed areas that get extra wet. It does well in dry situations. Further south where humidity is lower, it can work in depressed spots as long as they are not permanently wet.

• Mass spring flowers

• Vivid blue foliage

• Tough little plant

• Very frost tolerant

• Non invasive

CARE

Prune back every 2 to 3 years. Cut back to half way on mass planting areas. For gardens older leaves can be removed if that is preferable. For a more vivid blue colour use 8 to 12 months slow release fertiliser.

FLAMIN’® Phormium tenax ‘PHOS3’ PBR

A vibrant and midsized Phormium.

• More vibrant colour than other single colour Phormiums

• Mid sized

• Tougher than other purperea types

• Grows as well as green Phormiums

CARE

In gardens remove older leaves if ever needed. On roadsides, prune after 4 to 5 years if it gets too high for line of sight reasons or if it needs rejuvenating. It works well with out fertiliser, but will look more vibrant if 8 to 12 month slow release fertiliser is used.

SWEET MIST® Phormium tenax ‘PHOS2’ PBR

The richest colour and most dense, compact Phormium in Australia.

• Small

• Rich colour

• Stronger grower than Elfin

CARE

For gardens, if Sweet Mist ever gets discoloured foliage simply pull out dry looking bits. For mass planting like roadsides, the new foliage will after a period grow over the older looking foliage, so pruning should only be needed after 5 to 7 years. For a richer colour fertilise with an 8 to 12 month slow release fertiliser.

The Best Way To Prune Strappy Leaf Plants – Plant Pruning Tips

The Best Way To Prune Strappy Leaf Plants

By Todd Layt

Even with this selection of extremely low maintenance plants, it’s inevitable that some pruning will be needed. These tips give some often eye catching pruning techniques that will keep your landscape from looking hacked at.

Best Way To Prune Strappy Leaf Plants

Cassa Blue® Dianella caerulea ‘DBB03’ PBR

It performs extremely well in less humid regions.

• Blue foliage
• Very low seed set, so a safe environmental choice
• Mass flowering
• Excellent drought, frost and cold tolerance
• Good salt spray tolerance

CARE
Prune back half way every 3 to 5 years or alternatively, pull out older leaves. Performs better with 8 to 12 slow release fertiliser every 2 years.

Tanika® Lomandra longifolia ‘LM300’ PBR

Tanika is one of the most reliable and best landscape plants for all over

Australia (excluding alpine regions and high humidity areas).

• Sterile

• Evergreen winter and drought

• No irrigation needed

• Trim each 4 to 7 years

• One of the most reliable and best landscape plants for Australia

• Low fertiliser requirements

CARE

Trim in to a ball shape if needed, usually about half way and preferably trim every 3 to 7 years. Tanika ® Lomandra will live and prosper without pruning for more than a decade, but will look better with pruning after 3 to 7 years. If you’re in a high profile area, use slow release fertiliser every 1 to 2 years; 8 to 12 month preferably.

Tanika ® Lomandra will survive and prosper for more than a decade without fertiliser, but will look more dark green with fertiliser. Fertilising yearly will result in pruning being required after about 3 to 4 years. Thus if it is on a high profile site, use fertiliser, if a roadside, fertilise at time of planting only.

COLD

With fertiliser Tanika ® Lomandra usually stays evergreen down to -8 to -10°c. Has survived in the past down to -12°c. Avoid use in regions that have many days below -8°c in a row (eg alpine regions).

Tasred® Dianella tasmanica ‘TR20’ PBR

Performs well in many conditions in Perth, South Australia, Victoria, Tasmania, ACT and in NSW.

• Nice flowers and berries

• Has been grown with no known reseeding issues

• In colder parts it gets winter red growth on foliage

• Wide leaf looks like a compact wide leaf Phormium, but with really nice flowers

CARE

Prune back half way when needed each 3 to 7 years. It is more important to have a sharp implement for wider leaf plants. Sharp shears work well. Fertilise with 8 to 12 month slow release fertiliser if darker green foliage is desired.

Little Jess™ Dianella caerulea ‘DCMP01’ PBR

Little Jess is a great compact low maintenance plant for humid areas, and moderately cold areas.

• Mass purple flowers

• Compact

• Architectural shape

• Drought and moderately frost tolerant

• Non invasive

CARE

Prune every 2 to 3 years in gardens, and every 4 to 6 years on roadsides. Trim to half height. Avoid pruning in winter if possible. Slow release fertiliser is recommended for gardens every couple of years. Roadsides generally do OK without it, but for a darker foliage colour apply as for the garden.

Beware of using Lomandra confertifolia in mass planting

Beware of using Lomandra confertifolia in mass planting

Unless you follow certain rules

By Todd Layt

When compared to the more robust longifolia, fluviatilis, or hystrix types, Lomandra confertifolia is a smaller, slow growing, weaker Lomandra. Although Lomandra confertifolia types have been used on many sites they are slow to establish and they’ll often die due to lack of water during establishment, or are out competed by weeds.

If you are to use Lomandra confertifolia types, the smallest size pot to use is 140mm but due to the slowness of establishment you’d be better off using a minimum size pot of 175mm.

Another problem with using Lomandra confertifolia types in landscapes is that in frosts, they discolour much worse than longifolia or fluviatilis types. Also, due to their less vigorous root system they also struggle in the dry. In nature they’re generally found in slightly shaded areas. The best place to use Lomandra confertilfolia types is in gardens, where they can be maintained, and weeds can be removed. Used in mass plantings, they will be almost always overtaken by weeds.

WINGARRA® Lomandra contertifolia 'SIR5' PBR

Wingarra® Lomandra is the toughest of all confertifolia types, being unique in the fact it spreads from rhyzomes, and given maintenance for the first 18 months, it will spread and outcompete weeds. But it still needs a longer maintenance schedule than say Lomandra longifolia types like Tanika® Lomandra , Nyalla® Lomandra or hystrix types like Katie Belles™ Lomandra , or the new fluviatilis type called Shara™ Lomandra. The minimum size recommended for Wingarra® Lomandra is a 140mm pot.

Some of the new more blue types look pretty, but they die quite easily when the times get tough. Good garden plants for sure, but avoid them for mass planting. Part of the reason why they do not perform as well as the more vigorous Lomandra species in sunny mass planted areas, can be gleamed from the botanic text books. All the Lomandra confertifolia species described grow in dry sclerophyll forest with some shade, except for one type which grows in rocky sandstone type soils. This is probably the reason why most fail in humid type climates, as well as dry climates where it is full sun and heavy soil types.
