What to grow in June 2022

Now is a great time to grow some English spinach. It is one of the most nutritious vegetables, and an essential for vegetarians, as it contains most vitamins and minerals normally found in meats. It grows quickly; leaves can be picked as needed, and it freezes well for use in warmer weather.
Eastern parts of Australia have experienced an early start to winter with low temperatures and cold winds, which means it is time to start making marmalade, lemon curd or preserved lemons as citrus fruit ripens. Citrus for marmalades contains more pectin if harvested before the first frost. 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.
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during June 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, and grains can be sown directly into beds, as well as a green manure crop of barley, chickpea, red clover, broad bean (faba bean), field pea, or triticale. Lettuce, radicchio, English spinach and spring onions can be sown or planted out.

During Full Moon phase, mid and late season onions can be sown, and asparagus and rhubarb crowns can be planted, also deciduous fruit trees and vines where frosts are not severe. In very cold areas, leave planting of deciduous trees and vines until late winter.

What to grow in May 2022

It’s time to plant garlic in non-tropical warm and temperate climates, and sow garden peas in frost-free areas directly into a garden bed with a trellis to support the plants. Contrary to some garden guru advice, legumes do need compost or complete organic fertiliser added to the bed before sowing here as Australian soils do not naturally contain the rhizobia that fixes nitrogen in these plants.
If you live in a frost-prone climate, remember that peas take about 14 weeks from sowing to harvest, and time the sowing of peas so that they will not be flowering during frost periods. The plants are frost hardy but the flowers are not. Don’t cut back asparagus plant until the foliage yellows, which is a sign that plants have withdrawn nutrients into the crowns for growth next spring.

What to grow in April 2022

Why not grow some lavender near your vege patch this month to encourage more bees to visit your garden? See: French lavender
Give almond, cherry, nectarine, peach, and pear trees in all areas a drink of seaweed extract tea. Plant spring bulbs in temperate areas after Easter, and gardeners in temperate and cool climates can divide irises and day lilies.Scatter some dill seeds between brassica seedlings and scratch seeds into the soil surface. The smell of dill foliage confuses the butterflies and moths that like to lay their eggs on the leaves of the cabbage family.

what to grow in March 2022

Did you know you can increase the size and quality of your passionfruit crop with hand-pollination?
See: Passion fruit hand-pollination Passionfruit – hand pollination
March is a busy month in most gardens but this year we have high temperatures and fierce bushfires in the west and devastating floods in the east. If your patch has avoided these problems, check citrus trees for nutrient deficiencies, particularly magnesium (yellowing in older leaves) or iron (yellowing starts in young leaves). These deficiencies will affect the quality of your crop. See: Pale citrus leaves.
Give passionfruit vines that have produced a good summer crop a light application of complete organic fertiliser tucked under the outer edges of the mulch.
It is also time to select your spring-flowering bulbs for planting through autumn. Perennial bulbs are best planted during Full Moon phase.

What to grow in February 2022

Save the white tags from bread loaf bags and place one on a leaf edge of each brassica plant to fool cabbage white butterflies into thinking that eggs are already being laid on that plant. Or, scatter dill seed between your brassica plants, and scratch it lightly into the top soil, and water it in. The smell of dill confuses the pests that are attracted to this plant family.
Corn is wind-pollinated and, if you have netted your corn plants, or there is little wind in your garden, pollen may not reach every strand of silk that produces a kernel. You may have to hand pollinate to produce cobs filled with juicy kernels. Instructions for hand-pollinating can be found here: Improving corn pollination
If hot weather is predicted in your area, delay sowing lettuce until early next month, or it is likely to run to seed.

Banksia rose

This lovely climbing rose is a popular addition to many gardens. The Banksia Rose, (Rosa banksiae) or Lady Banks Rose, originated in China, and is named after the wife of famous botanist Sir Joseph Banks.
An evergreen rose with few, if any, thorns, it is a dense climber to about 6 metres – perfect for covering a fence or pergola. Masses of creamy yellow or white flowers are produced on long canes from spring onwards. The flowers have a delicate fragrance, some say reminiscent of violets.
PLANTING
This vigorous rose needs a well-drained soil in full sun or part shade where it won’t crowd out other plants. First fill the planting hole with water. This is important for two reasons. How quickly the hole drains indicates whether drainage is good or you will need to plant the rose in a raised mound. If the surrounding soil is not damp when you transplant, the water you apply after planting will be drawn away from the root ball into the surrounding dry soil, and the plant will look stressed several days after planting. The addition of compost to the planting hole, and a 5 cm layer of organic mulch to the soil surface, is very beneficial. Keep the mulch one hand width from the stem.
It is a hardy plant but it should be watered weekly for the first couple of months after planting if weather is dry. Then, only water when the top centimetre of soil is dry.
PRUNING
Climbing roses are pruned after flowering. Banksia roses are usually pruned by late summer when the main flowering flush has finished. As these roses flower on last season’s wood, just remove any damaged canes, and shorten the rest of the canes by one third. Hard pruning results in no flowers next spring. Prune new roses during First Quarter phase when sap flow is higher and growth response will be faster.

Citrus gall wasp

Galls or stem swellings on citrus trees need to be removed by pruning by the end of August, as very tiny black wasps emerge from the galls in September and October ready to lay a new batch of eggs in citrus stems. Because these wasps are poor fliers, they tend to reproduce on the same tree unless blown by wind to a new host.
Unlike many other wasps that assist pollination or are pest predators, the citrus gall wasp is a true pest. Eggs are laid in young stems of citrus trees, particularly lemon and grapefruit varieties, and the native finger lime. The larvae remain within the stem, stimulating the growth of cells, and causing a gall or swelling to form on the infested stem by early summer. Trees that are repeatedly attacked will become weaker and produce less fruit.
Originally, only coastal gardens of New South Wales and Queensland were affected, however, this wasp is spreading to other areas of Australia.
Do not add galls to the compost heap. Burn them, or dispose of them in a sealed plastic bag. It is very likely that the gall in the photo missed last year’s pruning because it is unusual for galls to reach that size in one season. As you can see, the tree in the photo is also affected by scale, and it is more common for citrus gall wasp to attack stressed trees. After pruning, water the tree thoroughly, and feed it with a complete organic fertiliser and as much compost as you can spare. A drink of seaweed extract tea will help it to resist further pest and disease attack.

Blossom end rot

A common problem affecting otherwise healthy tomato and capsicum plants during heat waves is blossom end rot, where partly formed fruit develops a dark, sunken patch furthest from the stem.
This is caused by calcium deficiency, and is not a disease. Like us, plants need a good supply of calcium to form a strong structure. Hot and very windy days increase transpiration (water loss) from plants in the same way we perspire to keep cool, and calcium can only be absorbed by plants as water-soluble, electrically-charged ions. This problem can also affect zucchini, pumpkin and melon plants.

During heat waves, daily watering rarely solves the problem. A deep watering a couple of times a week is more beneficial. If soil around plants is mulched to keep roots cooler and reduce water loss, an efficient way to water quickly is to place juice or soft drink bottles, neck down, beside plants. See: Watering in drought conditions

Other causes of blossom end rot are:

• Erratic watering
• Soil is too acidic (soil pH less than 6)
• Poor fertilising routine
• Overuse of fertilisers high in nitrogen or potassium, including some seaweed fertilisers
• Rarely, in very alkaline soil where calcium becomes insoluble.

Winter tomatoes

  There is nothing like the taste of vine-ripened tomatoes, and this is how my neighbour, Cheryl, keeps her tomatoes cropping through winter on the Mid-North Coast of NSW. The tomato plants self-seeded in the rose garden in front of her north-facing verandah and, as they grew, she trailed the foliage across the verandah surface. The plants get plenty of sun during the day and the verandah roof keeps the plants warmer at night and protects them from frost. This clever idea has worked very well and Cheryl has so many tomatoes, she has been giving them away.

Tomatoes can also do well during the colder months in pots on a protected north-facing verandah, as the potting mix in black plastic pots stays warmer than soil in garden beds. Fruiting on tomatoes depends on warm air and tomatoes do not need bees for pollination. Don’t forget to water the plants regularly, and give them a light application of complete organic fertiliser as flowers start to form, to ensure a sweet-tasting crop.

Compost – bins and tips

Compost Bins

Compost can be made in a variety of containers. The examples below show a double bin made from recycled timber, a double bin made from recycled, heavy gauge bird wire covered with knitted polypropylene shadecloth, and a commercial single bin. Double or triple bins are best as you can turn the compost from one bin into the next, with the third bin used to start a new heap.
dblcompost compostbins2

Homemade containers don’t require skilled carpentry. What goes into the compost container is more important than how it looks.

 

SAMSUNG DIGIMAX A503 SAMSUNG DIGIMAX A503 Compost tumblers (on right) do the work of aerating the mixture. They are suitable for composting small quantities of fairly soft ingredients quickly, for people who are not able to turn compost easily, but the mixture may not generate enough heat to kill diseases. The main points to remember in deciding on the size and site of your compost container are:

  • When ingredients form one cubic metre (i.e. 1 m. x 1 m. x 1 m.), aerobic bacteria will generate enough heat to kill diseases and weed seeds.
  • Open-base bins that are in contact with soil allow earthworms to enter the mixture (when it has cooled down) and provide worm castings to the mixture while they help complete the composting process.
  • Recommendations to position compost bins in full sun do not apply to many parts of Australia, as too much heat can kill off composting organisms. A shaded spot is ideal.
  • Compost bins need a cover to prevent the ingredients becoming sodden in heavy rain.

Some Composting Tips

If you are new to compost making, don’t be intimidated by statements of the ratio of carbon to nitrogen in compost making. Most recommended ingredients contain a mixture of both. With a little practice, you will quickly learn to identify and correct any imbalances.

  • Chop up tough items using shears, a shredder, or a sharp spade (spread items on soil or grass first to prevent jolting). This assists faster decomposition as bacteria work on the surfaces of organic waste. The more surfaces you can provide – the faster they can work.
  • The secret to making compost quickly to turn it regularly to keep it aerated, and to keep it damp as aerobic bacteria that commence the process require nitrogen, air and moisture to process the carbon.
  • The secret to fast composting is regular turning and mixing of the ingredients. Weekly turning while the ingredients are generating heat will produce mature compost very quickly. As the compost breaks down, the mass is reduced.
  • You don’t have to wait until you have a cubic metre of ingredients – turning and mixing ingredients will get the bacteria working.
  • If the pile looks grey or contains ants – it is too dry. Turn and mix the ingredients, while adding enough water to dampen the mixture.
  • Don’t be concerned about slaters in your compost heap. They feed on semi-decomposed organic matter.
  • If the pile is black with an unpleasant smell – it is over-wet. Air has been forced out, and anaerobic composting has begun. Turn and mix the ingredients, while dusting with agricultural lime every 15 cm, and adding some straw to the mix. Protect pile from rain.
  • If the pile seems inactive – it may need more nitrogen. Turn and mix the ingredients, while adding some manure every 20 cm. If manures are unavailable, you can substitute a generous sprinkling of poultry-based, organic-allowed fertiliser.
  • Your compost is ready when it is dark brown, crumbly, with a pleasant earthy smell and ingredients, apart from pieces of egg shell, are no longer recognisable. A 5 cm layer added to topsoil provides your garden with all the minerals that plants, animals and humans need for good health.
