Propagating Strawberries

In our area, propagating strawberries is usually a February job, but plants were late sending out runners this year due to the cooler summer. I like to use runners to grow some new plants each year, as vigorous, young strawberry plants are healthier and more productive. Once the new plants are growing well, I can thin out some of the older plants that are no longer performing well.
While our strawberry plants are fruiting, I put a plant marker next to the best producers. As soon as our strawberry plants finish fruiting and start to send out very long thin stems, I clear away the mulch to make it easier for the plants to take root. I then give the bed a drink of seaweed extract tea. Seaweed contains compounds that encourage root growth and build disease resistance.
At the end of each runner a small plant will form and tiny white roots will appear at the base (see photo A). Vigorous runners can produce two or three plantlets along each runner. I anchor plantlets from the best parent plants to the soil surface by placing a stone on the runner on the parent side of the plant. If the plantlet does not make good contact with soil, the roots will brown and the plantlet will die or grow poorly. Merely anchoring the plantlet to the soil surface allows the crown of the plant to sit on the soil surface where it should be. Strawberry crowns that become buried will rot.

When the plantlet has produced a strong root system (see photo B), the runner connecting it to the parent plant can be severed with secateurs or a sharp knife.

The new plant can then be left to grow where it is, or moved to another part of the bed so that all the plants have good air circulation. If I move new plants, I dig a wide shallow hole for each plant so that I can spread out the roots before covering them, and ensure that the crowns sit on the soil surface. I also remove all but one or two of the youngest leaves as this reduces any wilting after transplanting. I usually pot up some runners for spares too, just in case. Then, all that is required is regular watering and an occasional drink of manure tea until the plants are growing strongly. I don’t usually mulch them in autumn as the bare soil stays warmer and encourages the plants to produce plenty of healthy foliage so that next season’s berries will be hidden from birds.
Purists advise that runners should only be taken from plants that have not fruited because other plants are likely to be infected with strawberry virus. An aphid spreads this virus and we have never had aphids on our strawberry plants. As long as you use only runners from healthy, vigorous plants and use organic cultivation methods, there should not be a problem with runners that have fruited.

Garlic beds

It is still a bit too early to plant garlic in most areas, but not too early to prepare soil. Garlic needs a soil that is rich in humus but doesn’t require a lot of nitrogen so avoid adding manures to the bed. Uncomposted manures can cause garlic bulbs to rot, although processed poultry fertiliser is quite suitable for garlic. Garlic needs a full range of plant nutrients and trace elements for healthy growth. A drink of seaweed extract tea over the whole planting area will supply a full range of trace elements. Garlic also needs a soil pH of that is close to neutral. If you know that your soil is acid, give the bed a dose of dolomite or agricultural lime. Dissolve a generous handful in a full watering can and apply this to each square metre of the bed. Repeat again in a week or so for very acid soil.

Ladybirds

Ladybirds, except for the leaf-eating 26 or 28 spot ladybirds, are an asset to any garden. Both adults and larvae consume a considerable quantity of pests such as aphids and scale, and one type of ladybird feeds on fungus.
Most people know what adult ladybirds look like but ladybird larvae are strange looking creatures and many people confuse them with garden pests. As a result many of these hardworking pest predators are killed by pesticides, including organic sprays, and a decline in ladybird numbers is always followed by a pest outbreak. A common victim is the larvae of the Cottonycushion Scale ladybird which disguises it self so well, it is often mistaken for scale. A Brisbane web site has an excellent range of photos of ladybirds and their larvae. Check before you spray so that ladybirds won’t become an endangered species.

The cabbage family

This family, called the Brassicas, tend to be more susceptible to attack from the Cabbage Moth and the Cabbage White Butterfly when conditions are too warm for them or when the soil they are growing in is too acid for their liking, especially while the plants are young.
The cabbage family includes Brussels sprouts, Chinese cabbage, cauliflower, horseradish, kale, kohlrabi, mizuna, mustard greens, swede, tatsoi, turnip, watercress and stock, and is also related to radish. These plants need both boron and molybdenum for healthy growth and these are only available to plants when the soil pH is close to neutral. If you know that your soil is acid, and your Brassica plants are being attacked, give the bed a drink of dolomite or agricultural lime. Dissolve a generous handful in a full watering can and apply this to each square metre of the bed. Repeat the application if pests are still hanging around in two weeks.
In the meantime, remove all pest eggs from under leaves and leave crushed caterpillars on the leaves. This helps to deter further egg laying.

Saving tomato seed

To improve the quality of your tomato crop next year, save seed from one or two plants that have cropped well for you this year because these seeds will be from plants that have already adapted to your local growing conditions.
It is easy to save tomato seed from plants that were grown from open-pollinated seed. Hybrid seeds are unreliable because seed from hybrid varieties can be sterile, or revert to the traits of only one of the parent plants. A wide range of open-pollinated seed for tomatoes is available, with varieties to suit all Australian and New Zealand climate zones. You can order them by mail on the internet from companies including Greenpatch Seeds, Green Harvest or Eden Seeds.
To save tomato seed, first select one or two fully ripe tomatoes that you would like to grow next year. For medium to large tomatoes, one fruit is usually enough for the home gardener. For best results, keep them at room temperature until they are just beginning to get soft.
Then cut the tomato into segments and use a teaspoon to transfer the seeds and their surrounding jelly into a clean glass jar. For Italian type tomatoes that don’t contain a lot of jelly, you can add a very small amount of water to keep the seeds moist, but don’t drown them.
Leave the jar undisturbed in a warm place, out of direct sunlight, where you can observe fermentation. Within two or three days a foamy mould will form on the surface of the tomato mixture and it will look as though something has gone horribly wrong. Don’t worry. This is a beneficial fermentation process that kills off several diseases that can affect tomato plants, but the mould can cause premature germination of the seed, if it is left too long.
As soon as the thick foam forms, scoop it off and fill the jar will clean water. Viable seed sinks to the bottom of the jar. Carefully pour off loose jelly floating at the top of the jar, then pour the jar contents into a sieve. Wash the seeds thoroughly in the sieve to remove all the jelly, then tip the seeds onto a sheet of smooth paper. Avoid using paper towels for tomato seeds because they are hairy and difficult to remove from absorbent paper. Allow the seed to dry for thoroughly, indoors. After they have been drying for a few hours it is easy to rub them between your hands to separate any clumps of seed. I usually leave them to dry for a week before packaging in a paper envelope and storing in a biscuit tin in a cool place, until they are needed.

Excess tomatoes

tomatsd1.jpg
Sometimes home grown vegetables crop so well the family gets tired of eating them. If you find yourself with more tomatoes than you and your friends can use, freeze them for use during winter months. Vine-ripened tomatoes are a rich source of lycopene. This antioxidant helps keep the reproductive system healthy, and is said to be particularly beneficial to the prostate gland.
We use a simple method that has no added flavourings so that the thawed tomatoes can be used in soups, casseroles, or pasta sauces, as the occasion demands. Many flavours, such as onions, garlic and other herbs taste better when they haven’t been frozen.
We chop fully ripe tomatoes without peeling them as the skins float to the top of the pan during cooking, and can be skimmed off. Nor do we bother to remove the seeds but, if you don’t want seeds, you can either scoop them out with a teaspoon before cooking or put the cooked mixture through a sieve. Removing seeds before cooking also removes a lot of moisture from the tomato pulp and the seedless mixture requires constant stirring to prevent it sticking to the pan.
Place the chopped tomatoes in a heavy saucepan and gently heat to boiling, while stirring the mixture. Reduce heat, and allow tomatoes to simmer gently, uncovered, for about 20 minutes, stirring occasionally. Do not leave the mixture unattended as ripe tomatoes contain natural sugars and the mixture can stick if the heat is too high or the mixture is not moved around in the pan. After 20 minutes, turn off heat and cover the saucepan. Allow tomato pulp to cool, then ladle two, four or six cupfuls into separate freezer containers for later use.

No crops on cucumbers or squash?

This post has been updated. See Squash family not forming fruit?

The squash or Cucurbit family that includes chokoes, cucumbers, grammas, gourds, pumpkins, rockmelons, squash, watermelons, and zucchinis, produce both male and female flowers on the same plant, and rely on insects, such as bees, to pollinate the female flowers and produce fruit.
Although we eat many of this family as vegetables, in gardening terms, their produce is fruit.
With large areas of Australia experiencing prolonged overcast weather, and other areas experiencing smoke from bush fires, bee activity tends to be reduced and cucurbits may not be cropping. In circumstances like these, you may have to hand pollinate your plants to reap the benefits of your hard work. This is quite a simple procedure.
First identify the the female flowers on your vine or bush. At the base of each female flower you will find a miniature version of the mature fruit of that particular species. For example, cucumber vines produce what looks like a tiny gherkin at the base of each female flower while watermelon produce a watermelon miniature, often complete with stripes. The bases of male flowers, on the other hand,
join directly onto a vine stem.
Remove a male flower from the vine, and carefully peel back the petals so that the pollen bearing part in completely exposed. Then dab the centre of the male flower into the centre of a female flower. Repeat this process, replacing the male flower as pollen is removed. Then stand back, and allow nature to take its course.

If you can only find male flowers on your cucurbit vine, the problem takes a little longer to overcome. Pinch off the end of each long runner. This will stimulate the plant to produce side shoots called laterals. Some members of this family tend to produce female flowers on laterals. Once female flowers form, proceed with hand pollination if there are not many bees around.

If your cucurbit plant is producing small fruit that yellow and fall off before maturity, or turn mushy at the end furthest from the stem, you have a different problem altogether. Either you do not have enough calcium in your soil, or watering has been erratic and calcium has not been available when needed. Like us, plants need a good balance of calcium and magnesium to form a strong structure. Calcium and magnesium are required for growing tips of plants as well as fruit production and, if there is not enough of these nutrients to go around, growing tips will get priority. Dissolve a generous handful of dolomite (a mixture of calcium and magnesium) in a full watering can, and apply this around the root area of each plant – one full watering can per plant, or two around large vines such as pumpkin and watermelon. If you know that your soil has plenty of magnesium, you can use agricultural lime instead. §

A bit about me

Since completing a Landscape Gardening course thirty years ago, I have been actively involved in horticulture, garden design, writing articles for gardening magazines, and advising gardeners, including work at major retail nurseries. My husband and I are certified-organic gardeners and farmers on a small property on the lovely Mid North Coast of NSW where we grow fresh herbs for market, fruit and vegetables, and wine grapes. Although I originally learnt to garden by conventional methods, it wasn’t long before I was drawn to organic gardening because I could see the benefits for our family and the environment.
Over the years, I have collected many tips on how to get the best from gardens in Australian conditions. These have been compiled into my book, Easy Organic Gardening and Moon Planting, which was released by Scribe Publications in 2006.
