All that was recognisable when we uncovered the mound were the dried out stalks of the weeds. The rest had broken down, and mixed with the soil that had been attached to the weed roots, to create a soft dry tilth. It was now compost.
​
When last month's mini-drought occurred - the driest February on local records - we wondered if the weed compost might revive some seedlings that were suffering badly. The Wollastonia uniflora (left insert, below), planted in January, was only being kept alive with regular watering. We couldn't keep it up indefinitely.
We removed its worst leaves, and straightened the plant up in a deep bed of the compost, which was then watered in. Just four days later (main image) it was already recovering. It survived the March cyclone, and after its drought breaking rain, most of the 90 plants put in on January 18th now look healthy and happy.
We think the compost, created entirely from sunshine, and from weeds pulled within a few metres of the mound, played an important part in that survival. It gave the plants resilience against strong winds, and increased water retention in the surrounding soil. As a bonus, Bushcare's weed disposal no longer contributes to the island's carbon footprint. Every little bit helps.
​
We do understand that some feel the black plastic mounds are a bit of an eyesore, and we are open to any suggestions that might reduce that reaction. We will try to locate them in less conspicuous areas. As the weed load on our blocks diminishes, the compost heads should become smaller, and fewer.
