Kiwi Orchid Bark


Exciting new packaging for our Kiwi Orchid Bark range; 

New bark range New bark range New bark range

As a supplier we are always looking at innovative ideas to fulfil the needs of our customers and recently we reviewed our packaging to supply one of our international customers Jeffrey Newman of Newman's Nursery in Hawaii. On the 20th of May 2015 we sent a 40 foot container of Kiwi Orchid Bark to him in our new woven bags.(see pictures above for example of the product in the bags).

The feedback from Jeffrey was tremendous. He now put the bags of Kiwi Orchid Bark directly into a water/fertilizer mixture the night before use. Next morning, the bark had absorbed all moisture and added fertilizer, without even having to remove the product from the packaging. This minimized double handling of the Bark.

We are also trialling this packaging in shipments of Kiwi Orchid Bark to Australia. So far we have found they meet the quarantine requirements and stand up to the heat treatement. We will update you with the feedback from our Australian client, Graham Muller, when we receive it.

There are a number of significant advantages to supplying Kiwi Orchid Bark in Mesh bags;
-You can minimize double handling by placing the whole bag in a water/fertilized filled basin to hydrate before use. 
-Any moisture in a woven, bark filled bag, can disipate during transport and storage, rather than getting trapped in a plastic bag.
-Fumigation will effectively treat all the bark in these woven bags.
-Handling and stacking is easier, plastic bags can be slippery.
-If using only part of the contents the bag can be resealed and stored away.
-The bag can be reused for bark and other purposes.

At the moment we are working on green and labelled woven bags. These will be more aesthetically pleasing to customers and will allow for information labelling. 


 From Fred Clarke;

Kiwi Orchid Bark has been used exclusively at Sunset Valley Orchids for the last 5 years. Over that period we have grown and finished, in Kiwi Orchid Bark,over 100,000 orchid plants, including Cattleyas, Paphiopedilums, Australian Dendrobiums, Catasetums, Cymbidiums, Zygopetalums, Stanhopeans, and other genera. Compared to other pottingmedia I have used during 35 years of growing orchids and operating a commercial greenhouse, I have found it to be a superior product. I believe it is the best orchid potting media available.

Fred's pictures below show great root growth at several timescales again in Kiwi Orchid Bark made of Fresh Bark; a soilless, very open and well drained media as it should be.

From Graham Hill; Most Orchids have trees as their natural habitat where orchids thrive. You cannot get a fresher bark then that. A grower puts his orchids in pots to conveniently work with them. If one follows the logical line of thought, then one puts fresh bark in the pots to mimic the natural habitat. That is why "Kiwi Orchid Bark" is Fresh Bark and I use it for that reason.

From Fred Clarke;There has been a lot of propaganda regarding the benefits of treated bark (also referred to as aged or composted Bark). However, there are some drawbacks to composted bark. The composting of any organic material, including bark, causes acidification, the lowering of pH. To counteract this problem, lime is added to raise the pH back to neutral. Liming is holding the pH for about 18 to 24 months. After that the Ph begins to drop. When the pH drops the root system may suffer. This of course is a real problem. Root health is essential to growing good Orchids. 
It is possible to offset the pH drop by reliming composted bark. I am not sure how re-liming is best accomplished, as orchid media is a soilless, very open and well drained media. Research should be done on how best to accomplish this for growers using composted (aged) bark. One solution would be to re-pot once pH begins to drop this increases the costs. However, knowing when to do that is requiring constant monotoring and extra costs. 

I have experienced no such problems with Kiwi Orchid Bark and that is one of the main reasons I use it. Kiwi Orchid Bark holds up extremely well and exhibits little to no appreciable decay, even after 3-4 year.

All bark imported into the USA or Australia must, by law, be fumigated with Methyl bromide or heat treated. These important regulations are to assure that no unwanted organisms are introduced. Kiwi Orchid Bark is compliant with these regulations and as a result is 100 % free of pathogens and weed seeds.

At Bark Products Taranaki, every load of bark that comes in is inspected by the owners and followed through the milling process to assure the highest quality. The year to year consitency of Kiwi Orchid Bark has been exceptional. I am convinced that it is the best orchid bark on the market.

From Graham Hill; If a grower, using Fresh Bark lets it dry out it will be harder to get it moist again, but regular watering will avoid that.

I have a consideral amount of Orchid Books written by Ritterhausen, Rentoul, Northern and many more. None of them mentions aged bark

During a meeting of several growers the following list of advantages of Kiwi Orchid Bark over sphagnum moss was put together: 

  • substantial lower cost
  • no weeds
  • ease of handling
  • consistency
  • clean roots
  • stability in pots
  • no algae, liverwort or fine moss 

Kiwi Orchid Bark has a track record of reliability, cleanliness, uniform grading and longevity. Other customer comments on this product include; "It is so clean", "There is no dust in it so it will not smother the roots and we have less root problems using K.O.B.", "It is very even in size" and "It lasts a lot longer than all other orchid barks". 

Give Kiwi Orchid Bark a try and it will convince you, with its quality and performance, to be a "Game Changer" for you.
