what to grow in October 2021

October is a good gardening month, and a lot can be achieved. Apply a complete organic fertiliser to citrus after they have finished cropping. Make sure you add some complete organic fertiliser to beds before sowing bush and climbing beans as they do not fix nitrogen naturally in Australian soils. See: Fixing nitrogen.
This is also a good month to plant out flowering annuals and evergreen perennials, as well as sowing asparagus seed. Remember to give tomato, capsicum and chilli plants a light application of organic fertiliser as soon as they start to flower. Also deep, regular watering rather than a light watering daily will ensure that they have enough calcium to prevent Blossom end rot.
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during October 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).

What to grow in September 2021

September weather encourages many gardeners to start sowing. However, keep a watch on weather forecasts as a brief warm period in Spring can suddenly turn into a cold snap, and nights can be quite chilly. Keep an eye on seedlings and provide delicate species with a warm, sheltered spot before planting out when nights are warmer, or use a cloche to protect those you may have planted out too early.
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during September 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 my book Easy Organic Gardening and Moon Planting (Scribe Publications, 2006, 2009, 2012 and 2017, with moon planting 2017–2022), and e-book (Booktopia 2012, 2017).

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

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.
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during July in Australia and New Zealand.

What to grow in June 2021

June begins in Last Quarter phase, a great week to get those clean up jobs out of the way. Remember that peas and broad beans should be sown at a time that will avoid local frosts damaging the flowers, rather than strictly following set sowing times for temperate and cool areas. See: Broad beans and peas
Cold weather is setting in, and cold-sensitive seedlings in frosty areas will benefit from a ‘cloche’ to protect their tender leaves.
Check the soil pH around the cabbage family of plants. The pH should be close to neutral (7). When soil is too acid or alkaline, this group of plants is more likely to attract cabbage white butterfly and other pests

What to grow in May 2021

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.
It is International Composting Awareness Week from May 2 – 8 this year. For those who haven’t yet discovered all the wonderful benefits of compost, you can find more information here: Compost materials

What to grow in April 2021

As the weather cools, why not sow lots of English spinach directly into a garden bed. It grows quickly, is milder tasting than silverbeet, is rich in vitamins and minerals and, unlike silverbeet, freezes well for use when weather is too warm to grow spinach. Just blanch the leaves and stems, chop them and pack them into ice cube trays with a little water. Once frozen, the cubes can be transferred to a sealed plastic bag and stored in your freezer for use in soups, stews, quiches, rice dishes or Spanakopita. (Shown above is ‘Galilee’ spinach, the most heat-tolerant variety of true spinach.)
Add compost now to the bed where you plan to plant garlic during Full Moon phase towards the end of this month. Also check that soil pH is close to neutral (7.0). Gardeners in temperate climates can plant spring bulbs and lilies this month, and gardeners in temperate and cool climates can divide irises and day lilies.
The following gardening advice is an abbreviated list for vegetables, fruit trees and some culinary herbs that can be sown or planted during April in Australia and New Zealand.

Seeds not germinating?

Seeds lose their vigour over time and, they can deteriorate more quickly than they should if storage temperatures or moisture levels have been unsuitable. If a batch of seed has not germinated well I do a germination test on some of the seed to see if it’s worthwhile trying another crop.
All I need for this is a wide mouthed screw-top jar, a saucer, and some cotton wool.
I place the cotton wool in the centre of the saucer, and add enough water to wet it thoroughly – but not enough to allow it to float in the water. Seeds absorb a lot of water during germination, and inadequate moisture alone can cause germination failure. I then check that the cotton wool is covered by the inverted jar.
Then I sprinkle a sample of the seed from the suspect batch onto the cotton wool. If the seeds are large, such as corn or cucurbit seed, I use the blunt end of a pencil to press the seed firmly onto the surface of the cotton wool, so that they have good access to moisture. This is unnecessary with small seed.
When I place the jar over the cotton wool I have a miniature glasshouse. Most seeds require dark for germination; and I place the mini glasshouse in a dark cupboard that is not opened frequently. I check the jar every three days for signs of activity. To test if the cotton wool is still moist, I lift the jar and check that the cotton wool is still moist. If necessary, I add a few drops before replacing the jar.
Some vegetables such as most lettuces, cape gooseberry, seakale, shiso and tomatillo, and some herbs and gazanias require light for good germination. For these seeds the jar can be kept in a well-lit room out of direct sunlight. Seed packets will indicate the best conditions for that species’ germination.
Most common varieties of vegetable seeds will show activity in a fortnight or so, but some, including capsicum, carrot, celery, eggplant and parsley can require a month for germination to occur.
If the majority of the seeds show signs of germination, the problem is more likely to be the growing mixture, lack of adequate moisture, or unsuitable soil or growing mix temperatures. If germination is poor or the seeds don’t germinate at all, and the seed was purchased recently, the supplier should be contacted to replace the seed.
To reduce problems with seeds, packets should be kept in a cool stable environment where they are protected from moisture and pests. A metal biscuit tin makes a suitable storage container if the tin is kept in a cupboard in the centre of the house where temperature fluctuations are minimal.
