What to grow in August 2020

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: What’s soil pH?
If peas have been cropping well, give pea plants an application of seaweed liquid tea to help peas’ resistance to powdery mildew.
August 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
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during February in Australia and New Zealand. A comprehensive monthly guide that includes planting times for the entire garden, as well as when to fertilise, prune, weed, take cuttings or divide plants, can be found in the diary section of my book Easy Organic Gardening and Moon Planting (Scribe Publications, 2006, 2009, 2012, 2017), and e-book (Booktopia 2012, 2017).

* 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
Before the Full Moon, cabbage, open-headed Chinese cabbage, grain crops, lettuce, mizuna, silver beet, spring onions, tatsoi and dill can be sown or planted out, and rocket and a green manure crop of wheat can be sown directly into beds. Sow chickpea, nasturtium, and sunflower when soil feels warm to touch.

Sowing and planting this month will depend on whether your area is prone to frosts. Gardeners in Temperate areas with access to a cold frame can get an early start this month with some warmth-loving varieties.
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.
During First Quarter phase, capsicum, cucumber, leek and tomato can be sown in a cold frame.
During Full Moon phase, Jerusalem artichoke and potato can be sown directly into beds; also carrot in frost-free areas. Asparagus seed and beetroot can be sown in a cold frame. In frost-free areas, rosemary, thyme, avocado, and potted grapes can be planted.

COOL CLIMATE
August 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.)
During Full Moon phase, Jerusalem artichoke and potato can be sown directly into beds, and late season onions can be sown or planted out. Asparagus seed can be sown in a cold frame. Herbaceous perennial crowns can be planted. In very cold areas, deciduous trees, shrubs and vines can be planted.

What to grow in July 2020

July plantings are similar to those in June. Potatoes can be sown in warm temperate and temperate areas. Grape pruning should be completed this month. July is a good time to prune deciduous trees, shrubs and vines in frost-free areas.
General winter warning: If plants in your garden are damaged by frost, please resist the temptation to prune back the damaged parts until all danger of frost has passed. The damaged parts help protect the plants from further damage. There are several methods gardeners can use to protect seedlings or favourite shrubs and young trees. Seedlings cope well if you use a cloche. You can find tips for protecting shrubs and young trees, here:

During First Quarter phase, dwarf broad beans and peas can be sown directly into garden beds (see link in the June planting post on when to sow Broad beans and peas for your local climate).
During Full Moon phase, late season onions can be sown, and asparagus and rhubarb crowns, deciduous fruit trees and vines can be planted where frosts are not severe. In cold areas that receive winter rain, it is better to delay sowing potatoes until August.

What to grow in June 2020

It is not too late in most areas to correct pale citrus leaves. These are usually caused by either magnesium or iron deficiency. See: https://aussieorganicgardening.com/2009/04/pale-citrus-leaves/
Finally, cold weather is setting in, and seedlings in frosty areas will benefit from a ‘cloche’ to protect their tender leaves. A great time to start making marmalade, lemon curd or preserved lemons as citrus fruit ripens. It is also time to set up a support frame and sow broad beans and peas in temperate and cooler areas. ‘Coles Dwarf’ and ‘Egyptian’ are better varieties of broad beans for milder or windy conditions. Broad beans and peas love a humus-rich soil that is well-drained but avoid adding manures.

Heat wave help

With high temperatures predicted for many areas of mainland Australia this week, I would like to remind you that you can find tips on helping your garden to survive extremely hot temperatures here: Heat wave protection

Zing ginger

stemginger Recently, I received a sample of certified-organic Zing ginger, and it certainly suits its name. It was grown on Bauer’s Organic Farm in the Lockyer Valley. Rob Bauer is a very knowledgeable and dedicated certified-organic farmer and I always look out for his produce when shopping.
We use a lot of stem ginger, especially in stir fries, but it does not grow at its best in our area. At this time of year, we also make a delicious grapefruit and ginger cordial to use our excess fruit.
Ginger (Zingiber officinale) is an amazing herb. We all tend to add ginger to foods for flavour, however, ginger has a range of medicinal properties and you can find these are listed on the Zing website, although they seem to have forgotten its long history as a preventative for motion sickness. The Zing ginger site also provides 101 recipes of the many, different ways you can use this wonderful plant root.
Zing ginger can be found at Woolworths supermarkets.

Cloche for seedlings update

cloche With very cold weather set to continue over much of Australia for some time, gardeners can protect young seedlings with an easy-to-make cloche. This simple structure named for the French word for ‘bell’ keeps plants warm on chilly nights and can be easily ventilated so that they don’t get too warm during the day. When the nights are milder, the structure can be easily folded and stored until it is needed again.

Instructions for making cloches can be found here: Cloche for seedlings.
** And remember to leave frost-damaged parts on shrubs until all risk of frost has passed. They may look unattractive but the burnt portions are protecting the plants from further damage.

Watering in drought conditions

This week, two readers have asked me about garden problems caused by lack of water. As you know, it is extremely difficult to keep gardens well-watered in drought conditions. However, as plants can only absorb the nutrients they need for healthy growth and ripeness of crops as water-soluble ions, inadequate water is the cause of a wide range of problems, including pest attack.

Bare soil in garden beds and around trees, shrubs and vines allows a lot of soil moisture to be lost to evaporation. A 5 cm layer of organic mulch over beds and around larger plants (keeping it a hand span from the trunk) will prevent water applied to the soil from being wasted. Lawns are greedy and as their roots are close to the soil surface, they take water and nutrients intended for fruit trees and favourite ornamentals. Keep lawns beyond the outer canopy of trees and cover the area under trees with mulch.

wtrbttle.jpg A method that we have found very helpful to water mulched beds is to use plastic soft drink and juice bottles to funnel water through mulch directly to the root area of susceptible plants. This is a quick and very efficient way to hand water during drought, water restrictions, heat waves or windy weather. Limp tomato seedlings will freshen up in about 10 minutes after watering by this method.
Simply cut off the base of each container, remove the lids and bury the necks of the containers about 8 cm deep near outer edge of the foliage of plants. Large shrubs may require several containers. Pour water into the container until it begins to drain slowly – an indication that you have dampened the soil in the root area.

Seedlings and pot plants are usually the first to suffer during heat waves, and you can find advice on how to revive stressed pot plants here: Pot plant stress
