What to grow in August 2021

If you have a cold frame or a warm, protected verandah, you can get an early start on growing tomatoes in August. Sow seeds in small pots and, when they are about 15 cm high, lie the pots on their side. The stem will turn 90° to grow upright and auxiliary roots will start to grow along the horizontal part of the stem. Don’t forget to keep the pots watered. When planted out, these extra roots allow the plants to absorb more water and nutrients, and help keep the plants less stressed in the heat waves that are becoming more common.
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 August 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 with moon planting 2017–2022), 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.
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.

WARM CLIMATE Rockhampton and northwards
Gardeners in very warm areas have time to sow late crops of many varieties.

TEMPERATE CLIMATE
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.
Before the Full Moon, English spinach can be sown directly into beds, as well as a green manure crop of broad bean (Faba bean) or field pea. Celery, leek and lettuce can be sown in a cold frame.
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 2021

July begins in Last Quarter phase this year – not the best phase for sowing seeds but good for general garden maintenance. Plantings in July are very similar to those for June, but in areas experiencing very cold winters with late frosts peas can be planted later because pea plants are frost hardy but the flowers are not. Don’t forget to snap some outer leaves of cauliflower plants and bend them over the curd to prevent the curds discolouring in sunlight.
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.

Different time zones

The times for Moon phase changes on the right hand panel of this blog are Australian Eastern Standard Time (AEST), which only applies to the east coast of Australia, and the phase will change at a different time in central or western Australia, or in other southern hemisphere countries.
As converting AEST to local time zones can be confusing for gardeners, I have added a link to a Time Converter to the Moon Planting widget to make it easier. Just follow the instructions in the Moon Planting widget.

Spring equinox 2010

What is an equinox? It is a time when day and night are of equal length, and tomorrow (23rd of September) is the Spring Equinox in the southern hemisphere. Our equinoxes are the opposite of those in the northern hemisphere.
There are two equinoxes each year – one around the 23rd or 24th of September and the other on 21st of March – our Fall Equinox. After the Spring Equinox the days get longer until around our Summer Solstice on, or around the 22nd of December, then days become gradually shorter.
Some cultures think that the Spring Equinox has a special significance for planting. However, at least a third of the time the spring equinox occurs when the Moon is in a ‘barren sign’, or at New or Full Moon, which are not good times for sowing seeds.
Tomorrow’s equinox occurs on a Full Moon, so wait until after 7:20 am AEST on 24th before you sow root crops or plant perennials.

Winter pruning

A Full Moon phase during winter is a good time to prune most deciduous plants. From 19th of this month is a good time to prune dormant trees and vines that tend to bleed (weep sap) if pruned in late winter. These include grapes, kiwi fruit, mulberry, birch, conifers, frangipani, maple and poplar. Pecans, which bleed readily and require minimal pruning, are best pruned during Last Quarter phase (from June 26th) when sap flow is lowest. Almonds should also be pruned early in winter because they flower earlier than other Prunus species. Other deciduous fruit trees can be pruned in winter with the exception of apricots and cherries. These trees are prone to bacterial canker if pruned when sap flow is low and cuts are slow to heal. Young apricot and cherry trees can be pruned in spring during First Quarter phase, and mature trees pruned after harvest during a Full Moon phase. Deciduous fruit trees grown for spring flowers rather than fruit are pruned during a First Quarter phase, after flowering.
It is a good idea to keep a container of methylated spirits with you when pruning and regularly wipe the blades of your pruning tools to avoid the risk of spreading and bacteria or fungal spores from one plant to another.

Pruning roses
In most areas, bush roses can be pruned during a Full Moon phase in winter, after they become dormant. If you have removed dead wood, suckers and crossed branches during the growing season, little winter pruning will be required. Where frosts are common, or rose canker (dieback) has been a problem, it is better to prune bush roses as late as possible – at the first sign of new growth when sap flow is higher. Then prune, with slanting cuts, during First Quarter phase to encourage strong growth. This will help reduce dieback because the fungus that causes rose canker lives on rose thorns. Roses are more susceptible to infection by this fungus when sap flow is slow and pruning cuts heal slowly. Careful pruning is the only way to avoid dieback, as there is no treatment for the fungus.
Climbing roses that are floribunda or hybrid tea sports can be pruned at the same time as bush roses, but climbers that only flower in spring are pruned before a Full Moon, after flowering.

Full Moon and cauliflower?

It is not surprising that some people don’t take moon planting seriously when TV commercials make statements like “the increased light of the Full Moon has hastened maturation of cauliflowers”.
All vegetables are exposed to light from Full Moons. Maturity times for different varieties of cauliflower vary from 11- 26 weeks, so the slower growing ones would be exposed to more Full Moons than the faster-growing varieties. In fact, radishes, which are sown after the Full Moon, can mature in a month, and would be exposed to the least amount of Full Moon light.
I thought the statement may have been based on the Moon being in Perigee (closest part of its orbit to Earth) and the reflected light from the Full Moon being slightly stronger. However, the only time the Full Moon was near perigee this year was back in January. Cauliflowers require cold weather to form the curd, and the coldest weather normally occurs when the days are shortest and the plants are exposed to less sunlight. It is more likely that the cooler temperatures this year have assisted the early maturation of cauliflowers, and that TV ad doesn’t make a whole lot of sense to me.
