Microbats

Microbat This odd little character often hangs out on our front verandah. He is one of the many species of microbat found in Australia and is 6 cm long when he is all tucked up and asleep. The reason he is odd is that he is always alone, eschewing the company of the colony of microbats we see dashing between the tree tops at dusk, and he sleeps on our verandah at night when bats normally forage for food.

Microbats are very helpful in the garden as they consume a huge quantity of mosquitos, moths and other insect pests. If you are fortunate enough to have a colony of microbats on your property, please avoid using chemical pesticides.

Windy weather update

Transpiratiion Predictions are for more cold, windy weather on the way. Keep a close watch on your garden as wind can dry out soils faster than summer heat, resulting in cell collapse of soft tissue plants. To discover why this happens and how to protect your plants, see: Windy weather
Seedlings and many vegetable crops are vulnerable to wind damage in winter and early spring. Ripening citrus are also easily damaged by strong winds.

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.

Garlic planting time – again

garlic1 March and April are good months for planting garlic in temperate to warmer parts of Australia. This year we are going back to growing the ‘Italian White‘ variety as our winters are becoming too mild for the hard-necked varieties. ‘Italian White‘ is a soft-necked garlic more suited to warmer areas. Cloves are slightly smaller than the purple hard-necked garlic but it has a lovely flavour and keeps longer than the hard-neck varieties.

We will sow ours in the middle of April (during Full Moon phase), after separating the knobs into individual cloves. The larger cloves from each knob will be planted, flat end down, just below the surface into soil rich in compost with a pH close to neutral. We usually plant our cloves 15 cm apart in rows 30 cm apart so that the canopy formed by the leaves helps to keep the mulched soil cooler. Garlic needs regular, deep watering (not a daily sprinkle) and hates competing with weeds. Green Harvest has a range of garlic for planting, and their garlic page will help you to decide which variety is best suited to your local climate and needs.

If you want to grow a small quantity of garlic from knobs purchased from your greengrocer, make sure it is Australian garlic. Imported garlic is treated with methyl bromide, a nasty gas that has been banned in Europe and may prevent cloves from growing.
Garlic takes 6 to 8 months to develop a bulb depending on the variety and climate.

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.

Strawberries – starting new plants

strawbrrs

Vigorous, young strawberry plants produce the best berries. As strawberry cropping slows, plants produce long horizontal stems (runners). Along each runner a small plantlet begins to form and tiny white roots will appear at the base – see photos below. Vigorous runners can produce two or three plantlets along each runner. If you remove mulch from the area under each new plantlet and anchor plantlets to the soil surface by placing a stone on the runner on the parent side of each plantlet, you can produce many new plants for your strawberry patch. Anchoring plantlets in this way allows the crown of the plantlet to sit on the soil surface. (Strawberry crowns will rot if buried.) If your strawberry bed contains plenty of organic matter, all you need to do is give the bed a drink of seaweed extract tea to stimulate root growth and build disease resistance, and keep the soil damp. Otherwise, add a handful of mature compost to the soil surface under each plantlet. Each parent plant will provide nourishment to the new plants until they develop enough roots to grow independently.

When plantlets are well established in autumn, the runners connecting them to the parent plant can be cut, and the new plants can be left where they are or transplanted to a new spot.
Tip: While strawberries are still cropping, place a marker beside the plants that produce the best berries and only use the runners from these plants to improve the quality of produce in your strawberry patch.

Organic fruit – mangoes

Mangoes Lunch today included delicious organic mangoes. These were grown by Naturally Fresh P/L up near Bowen Queensland, and carry the Freshcare chemical-free label. Look out for these at your local supplier – they have a beautiful flavour and texture.
When organic farmers can grow such delicious, healthy fruits without chemical pesticides or irradiation, you have to wonder at the farmers who kick up a fuss about restrictions on the use of the neurotoxic systemic* pesticides dimethoate and fenthion.
* Systemic means you cannot wash the pesticide from the produce, it is absorbed through the whole plant.

Heat wave protection

Some parts of Australia are enduring extremely hot weather and, apparently, there is more to come this summer. Periods of intense heat can cause scorching in many gardens.
Although European-based garden texts recommend full sun for most vegetables, where summers are hot and air pollution is low, full sun can result in sunscald. While Australian natives have evolved to restrict loss of water through leaves in hot, dry conditions, very hot plants, especially those that originated in cooler Northern Hemisphere regions – such as most of our vegetables and fruits, lose a lot of water through their leaves in an effort to keep cool, in a similar way to humans perspiring.

A bit of shade
shdeclth Providing some light shade during the hottest part of the day can prevent sunscald on susceptible crops, and, by keeping the plants cooler, reduces their water consumption, an important consideration where water restrictions apply. We use lightweight, knitted shade cloth, supported by arches made from 38 mm irrigation pipe attached to garden stakes or star stakes, or you can use old light-weight curtains or sheets.
Each canopy is positioned to allow morning sun to reach plants, yet not restrict air flow around them. Poor air flow (such as in fully enclosed areas) can produce conditions suitable for some fungal diseases to establish. Instructions for making these can be found in the post Sun and heat protection.
However, in an emergency, any old curtains or pieces of lightweight fabric will do. Tie the corners to garden stakes to provide some relief for garden beds during the hottest part of the day.
If possible, move potted plants to a shaded area of the garden, and group them together. This provides more humidity around the plants, and reduces their water requirements.

Water is essential
wtrbttle.jpg Adequate soil moisture is essential for your vegetable garden to maintain good growth during heat waves. Mulching garden beds is very helpful. A method that we have found very helpful to water mulched beds 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, 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

Water for wildlife
Birdbath Don’t forget to provide water for birds and bees that visit your garden. A bird bath, or containers of clean water positioned where cats and dogs can’t reach them will provide relief for the insect-eating birds and the bees that pollinate your crops. Chlorinated pool water is toxic to these helpful creatures. A container of water under shaded foliage will be appreciated by your resident frogs too.
