I regularly get emails from readers who have added mushroom compost, biochar or wood ash to their garden beds or compost bins and find that their plants are not growing very well. These products can all raise soil or compost pH to 8.5 or 9. Soil pH is very important as it controls which nutrients are available to plants. Because pH is expressed in negative logarithms, a soil pH of 9 is 100 times more alkaline than the neutral reading of 7 where all nutrients are available. The way to avoid this problem is to test the pH of all of these products, including bagged compost and manures before digging them into garden beds.
Reliable test kits are available from Bunnings (currently about $18.30) and are a worthwhile investment to keep your plants healthy. See:立博比威廉希尔高
If peas have been cropping well, give pea plants an application of seaweed liquid tea to help peas’ resistance to powdery mildew.
八月is the last month you can effectively get rid of Bindii (or Jo-jo as it is called in some places), as it will have produced flower heads by mid spring. The flower heads contain vicious spines. You can find methods of eradication of this pest here:Bindii or Jo-jo

* For gardeners who do not use moon planting: sow or plant out any of the following list at any time this month, although you may find germination rates are lower when the Moon is in Last Quarter phase..
WARM CLIMATE–South of Rockhampton
During First Quarter phase, bush and climbing beans, and rosella can be sown. Capsicum, cucumber, eggplant, rockmelon, summer squash, tomato, watermelon and zucchini can be sown in a cold frame or warm, protected area.
During Full Moon phase, carrot, Jerusalem artichoke, potato (Brisbane and areas south), and radish can be sown directly into beds. Asparagus seed, beetroot, rosemary, thyme and watercress can be sown or planted out. Avocado, citrus, macadamia and potted grapes can be planted.
Gardeners in very warm areas have time to sow late crops of many varieties.
Before the Full Moon, cabbage, lettuce, parsley, and spring onions can be sown or planted out. Grain crops, NZ spinach, silver beet and sunflower can be sown directly into beds, as well as a green manure crop of wheat or lablab.
During First Quarter phase, capsicum, cucumber, eggplant, parsley, rockmelon, rosella, summer squash, sweet corn, tomato, watermelon and zucchini can be sown or planted out. Bush and climbing beans and sweet corn can be sown directly into beds.
Before the Full Moon, grain crops and mizuna can be sown directly into beds, as well as a green manure crop of clover, field pea, barley, or wheat. Dwarf peas and chamomile can be sown directly into beds in colder areas. Celery, leek and lettuce can be sown in a cold frame.
In frost-free areas, Chinese cabbage, rocket, silver beet, spring onions, tatsoi and coriander can also be sown directly into beds.
八月is still too cold and frosty for most plantings.
During First Quarter phase, dwarf peas can be sown directly into beds. Tomatoes and chamomile can be sown in a cold frame. In very cold areas, broad beans can be sown. (See post on when to sow Broad beans and peas for your local climate.)
