Aubergine (eggplant)

eggplantwht Have you ever wondered why they were called eggplants? This variety is the reason. The small white fruit, which look like hens’ eggs hanging on a bush, has a delicious flavour but has been very difficult to find in recent years and I was delighted to finally find some seeds. Yates has ‘White Star’ and there is a variety called ‘Easter Egg’ available from an Australian grower on eBay.

Aubergines (Solanum melangena) are a member of the tomato family and require a similar position, soil preparation, and soil pH. However, they require warmer conditions for germination than tomatoes and are usually sown 1 cm deep in small pots in a warm, protected position. The small, white variety produces a compact bush and can be grown in beds or pots. Aubergines need staking because the stems are brittle, and they appreciate a light application of poultry-based, complete fertiliser as buds form. Regular harvesting increases production. Cut fruit from the plant with a 2 cm stem when the skin is firm and shiny.

Frangipani from seed update

This method of frangipani propagation is becoming popular with readers, and one of our readers, Margaret, has been kind enough to share some photos of her very successful efforts.

Why choose this method of propagation? Frangipani grown from seed grow more quickly than trees grown from cuttings and, in the same way a family of children or animals can inherit different combinations of their parents’ genes, plants grown from seed may demonstrate different characteristics of parent plants, sometimes resulting in spectacular new varieties. Plants grown from cuttings are an exact copy on one parent. Not only may the flowers vary in colour or form, we have found that the perfumes of different-coloured frangipani also vary.

We have multiple trees of four different frangipani and the orange one reminds me of the smell of ripe peaches, while the deep pink one has a sweet citrus smell, and the pale pink one hardly any perfume at all.

French beans

OLYMPUS DIGITAL CAMERA Occasionally, garden gurus will say that “beans will grow on the smell of an empty fertiliser bag because they will fix nitrogen in the soil”. This is not true in Australia, where the soil bacteria that is necessary for these legumes to fix nitrogen does not occur naturally. Gardeners are often then disappointed to find that the lower leaves of their beans and peas have yellowed.
French or green beans (and peas) will benefit from the addition of some mature compost and a light application of complete fertiliser when preparing the planting area. Plants need more than nitrogen to be healthy and produce good crops, and compost in soil helps beans resist bean fly.
French beans do well in a sunny position with a soil pH not lower than 6. However, they may need some temporary shade during our heat wave conditions. Regular, deep watering and a 5 cm layer of mulch over the bed will help to keep them growing strongly. Bush varieties of French beans grow best when sown in a block rather than rows, and can be ready to harvest in eight to ten weeks after sowing.
For a continuous supply, sow a small quantity each month listed in the monthly planting guide for your climate.

Grapefruit and ginger cordial

This cordial is popular with children and makes a delicious mixer for adult drinks.
(yields about 600 ml):
Prep/cooking time: about 20 min. plus chilling..

250 ml pink or yellow grapefruit juice (2-3 fruits)
250 g white sugar
250 ml water
Fresh ginger to taste (I used 2-3 cm)

Juice the grapefruits. Peel the ginger and slice it thinly.
Pour the grapefruit juice into a small saucepan, add the sugar and water as well as the sliced ginger. Bring to a boil and allow to simmer until sugar has completely dissolved.
Remove from heat and let stand for 10 to 15 minutes. Pour through a fine mesh sieve into a sterilised bottle and refrigerate the strained syrup until thoroughly chilled. Seal the bottle. Store in the refrigerator.
To cut the sweetness, dilute with water or soda water and ice cubes.

Corn – improving pollination

All types of corn are pollinated by breezes that blow pollen from the male flowers onto the silk threads that emerge from the top of each ear of corn. This is why it is better for home gardeners to grow corn in a block rather than a long row. Each strand of silk is connected to a separate immature seed and is covered in tiny sticky hairs that collect the pollen. If some silk strands don’t receive pollen, kernels may not form along one side of a cob, or near the top of the cob. (Female part of corn plant in photo at left.)

Male flowers form at the top of the corn plant as an upright spike and lower branches that open out like umbrella spokes. Pollen forms in small yellow ovals (anthers) that release their pollen mid morning after dew has dried from the flowers (between about 9 and 11 am). The centre spike is the first part to release its pollen. Pollen release may only last from 3 to 5 days and the released pollen is only viable for up to 24 hours. (Male flower in photo at left.)
It can help when growing small quantities of sweet corn or popcorn to pollinate it by hand, to ensure that the cobs your plants produce are full of juicy kernels. In nature, silks are rarely pollinated by the same plant.

To ensure good pollination, you need a sheet of A4 paper and a clean, dry, soft paintbrush. Fold the paper in half lengthways and open it out, then fold it in half the opposite way and open it out. This helps the paper to form a shallow well. Or, you can use a small clean shallow tray – something easy to manoeuvre between the plants. Hold the paper under a male flower and gently tap the spike and lower branches of the male flower with the handle of the paint brush. When tassels are ready to be pollinated, plenty of bright yellow pollen will fall onto the paper. Collect some of the pollen on the hairs of the paintbrush and dab it onto all sides and the centre of silk strands of other corn plants. Repeat this process over several days. Once a tassel has been pollinated, the ends of the silk strands will start to turn brown. As the cobs mature, you may have to net your corn crop as birds know when corn is perfect for eating.
Corn anthers won’t release pollen when conditions are too wet or very dry, the plants will wait until conditions are favourable. In areas of Australia that experience long periods of rain, it is best to plan your corn crop to avoid the wet season.

Snake beans

Snake bean vine Snake beans are a good value crop for the vege patch where summers are hot, and French beans may struggle or be attacked by birds. They are prolific croppers over a long period and 4 plants are probably sufficient to supply a family of 4. Ours were still cropping at the beginning of June this year. A popular ingredient in Asian dishes, they can be substituted for French beans in many recipes, and blanched, young beans can be added to salads.

Snake bean pods Snake beans can grow up to half a metre or longer but tend to become a little tough if allowed to grow to this length (i.e. the beans at the bottom of the photo). They are best eaten when 30 cm or so in length while seeds are small, and they are young and tender. Pods grow fast and should be picked every day, or every second day at least, to ensure that they are harvested at their best, and to keep the vines forming new pods.
Snake beans take up very little space in the garden as they are grown on a trellis in soil that has plenty of compost and some organic complete fertiliser added, which should keep the soil pH at an ideal level (6.5–7). In late spring, when soil temperature is at least 15 degrees Celsius, sow seeds in damp soil 1 cm deep and 30 cm apart. Water to settle soil after sowing. Do not water the soil again until seed leaves appear, then water regularly to ensure healthy growth. In tropical areas where summer rainfall is heavy, sow seeds in hills to improve drainage. Seeds germinate quickly, and vines can produce pods in 60 days in very hot weather.
Snake bean ripening Greenpatch Organic Seeds has two varieties of snake bean; one with black seeds that produces pods up to 45 cm and one with brown seeds than produces thin pods to 60 cm.
Allow a couple of pods to mature until they have yellowed and lost their ‘puffiness’ (see photo). Then continue the drying process indoors. De-pod seeds when pods are crisp.

Time to plant spring bulbs

Just a reminder that April is a good time for planting spring-flowering bulbs in most areas. Gardeners in warmer climates can put bulbs into the vegetable crisper of the fridge for a month’s chilling before planting in May.
Add plenty of compost and some complete organic complete fertiliser to the planting area. Nutrients will be absorbed by the plants during the growing season and withdrawn into the bulbs as the foliage dies back to ensure good flowering the following season, so remember not to remove foliage before it becomes brown. Bulbs are normally planted at a depth twice the width of the bulb. In warm climates, plant suitable bulbs up to twice as deep as indicated on the packet. After planting, mulch the area in early morning when the soil is cooler and keep the planted area just damp until growth appears, then water regularly. For moon planters, Full Moon phase is the best time to plant bulbs. This year (2014) the Full Moon occurs on 15th of April and May.

Scallions or Spring onions

True scallions (Allium fistulosum) that originated in the Far East do not form a bulb. Also known in Australia as spring onions or green onions, these onions are a versatile herb that are used as raw or cooked vegetables In some areas they are sold as shallots, however, true shallots (Allium aggregatum) form a light brown bulb. Scallions are harvested as required as they cannot be stored for long periods. Their pencil-thick stems and hollow green leaves provide a mild flavour used raw in salads, or cooked in many Asian dishes. Chinese herbalists value them for various medicinal properties.
Scallions are easy to grow in all climate zones in Australia, and can be ready to harvest in 8 – 10 weeks. Young seedlings respond well in a compost-rich soil and an application of weak, fermented manure tea watered in several days after transplanting.
Seed of green onions does not keep for long and seed collected for sowing next season will produce a vigorous crop as this seed will have come from plants that have adapted to your local soil and climate conditions. Leave several of your green onion plants to produce seed from their globular flower heads (umbrels).

Excess figs

Brown Turkey Our ‘Brown Turkey’ tree has produced lots of lovely, sweet figs this hot, dry summer – far too many for the two of us to eat. Not wanting to waste any of these delicious fruits, I searched my recipe books for a way to use the excess figs and came across a recipe for fig and ginger conserve. With a slight variation in the method from the original recipe it produces a thick jam that is scrumptious on crackers with some Brie or tasty cheese.

FIG AND GINGER CONSERVE
1 kg ripe figs
1/2 cup orange juice
2 Tablespoons lemon juice
1 Tablespoon sweet sherry
1 1/2 Tablespoons grated fresh ginger
2 cups sugar

Gently wash figs, remove stems and chop roughly.
Combine figs, juices, sherry and ginger in a saucepan. Bring to the boil and simmer, covered, until figs are soft (about 15¬20 minutes).
Stir in sugar over simmering heat until sugar is dissolved. Bring mixture to the boil, reduce heat to simmer and stir continuously to prevent sticking until mixture is quite thick.
Transfer mixture to hot sterilised jars, and seal.

Windy weather

Transpiration Garden beds dry out very quickly in windy weather, including those beds protected by mulch. The reason is that plants maintain some humidity around them by drawing water from the soil and releasing it through tiny holes in their leaves, a process known as transpiration. As strong wind constantly removes the moisture, more and more water is drawn from the soil in an effort to maintain humidity. As soil dries out, cells collapse in the soft tissues of plants causing drooping of plants and possibly death of small seedlings.
A way to avoid this problem in windy weather is to use plastic soft drink and juice bottles to funnel water directly to the root area of susceptible plants. This is a quick and very efficient way to hand water during water restrictions or windy weather. Limp tomato seedlings will freshen up in about 10 minutes after watering by this method.

wtrbttle.jpg 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.


For plants that are generally sensitive to wind, filtering the wind rather than blocking it provides better protection for delicate plants. A solid cover or wall causes wind to whirl around on both sides of the screen, but a lattice trellis or product called ‘Windbreak’ on the side of the prevailing wind reduces the impact of the wind, as indicated below.
