The NSW Branch of the AIH has received advice from it’s members of pH related problems with soil mixes
Typically, the pH when tested has been in the range of 8.8 to 9.0 and consequently, plants have suffered.
To ensure good quality control and preserve the professional reputations of it’s members, AIH NSW is recommending that any soil mix used by it’s members should be pH tested prior to their accepting delivery.
The pH problem has been experienced across a variety of soil mixes and suppliers.
They are hoping to work with members to improve this quality control issue.
This is very disappointing. well done AIH in picking up and addressing the problem.
This information will be circulated to all AILDM members via our newsletter and forum.
I’m in retail nursery up in Brisbane. I see people who have had a “landscape job” done and now, 1-3 months later, the plants have gone off… stunted, yellow etc…
When tested, the soil pH is 8, at best, to 9, but I’ve actually measured 10 on one occasion.
These devestated people can’t believe how (with application of sulphur in small increments and remeasuring pH) their garden blooms in a few months… proof in the pudding.
They are confused having spent money on fertilizer and more fertilizer and pesticides and what not.
