My Grandfather’s Strawberries
Strawberry! Fragaria sp.
This relative of the Rose has delicate runners with charming flowers in white and shades of pink that makes Strawberries an attractive option for pots and baskets. Let’s be honest though we don’t grow strawberries for the flowers, we grow it for the delightful fruit that comes after the flowers!
Growing Strawberries is relatively easy pending conditions and the ever decreasing chance of pollination.
They need deep, rich and friable soil in a position that gets full to part sun. I always add some compost before I plant, never mushroom compost, as Strawberries like slightly acidic soil (pH of 6 – 6.5). My grandfather always mounded up his strawberry patch, left about 30cm between each plant and heavily sugar caned mulched the strawberry patch. The mulching helps prevent fungal diseases, reduces weed invasion and also stops the strawberry fruit from sitting on the bare dirt and rotting away.
Strawberries like moist soil but not really wet. They are very surface rooted so they need regular watering as they can dry out pretty quickly. Once you see the fruit forming you can ease up a little on the watering.
My grandfather would feed his strawberries with Organic Link and Triple Boost in beginning but as soon as the plants got big and leaves turned a lovely deep green colour, he would start to Silica and Potash every second week.

Crop rotation is very important with strawberries. It is recommended that you move your strawberries to a new patch, with fresh soil, every three years. My Grandfather would let his strawberries form runners at the end of the new seasons plants and direct the runners towards the strawberries new patch of ground. Then every two years he would pull up his old strawberries and let the ground lie fallow for a season or two. Strawberries shouldn’t be planted where tomatoes, eggplants, capsicums or chillis have been for at least three years as they have a tendency to pass on a plethora of fungal diseases.
While Strawberries are very easy to grow they can have a few problems.
Mould and fungus can be an issue, especially when the air is cold and there is water hanging around on the foliage. Best way to prevent this is to water in the early hours of the morning. Snails, slugs and birds can be an issue once the fruit start to form. You can use snail and slug pellets and for birds my grandfather used to use old cds (reflective things scare birds away). You can also use fruit protection netting.
I find growing strawberries in pots or hanging baskets works wonderfully and I don’t have any problems with snails eating my fruit. I use Platinum potting mix and fertilise the same as if they were in the ground.
'Vivipary' on a strawberry fruit
Sometimes a phenomena known as 'Vivipary' can occur on your strawberries. In a few words this just means that the seed is germinating before it is naturally shed as is the natural order of things. I have read of others who have attempted to grow these seedlings on but have not tried it myself. By all accounts each seedling grows on to be a normal healthy plant of the the mother plant.
Some of you may be asking why don’t we grow strawberries from seed?
Simple answer is some plants are just too much of a hassle to grow from seed and Strawberries would have to top this list. I have actually read they are one of the hardest plants to germinate by seed and it can take up to two years before the plant even contemplates producing strawberries.
One website gives this tip for germinating strawberry seeds “Tuck your strawberry seed packet inside a sealed plastic bag or airtight container and place in your freezer for 3-4 weeks. When you remove the bag or container, do not break the seal until it (and its living contents) have reached room temperature....... Opening the package too quickly may result in water condensing on the cold seeds, and this will reduce your chances of success.” Seriously, some plants are better off being bought ready made.
Trevallan stocks a few different strawberries, some are available all year, some are only available from May to July. My grandfather always said Autumn is best time to plant strawberries but really any time is a good time to plant something.
STRAWBERRY LOWANNA only available in 125mm pots or bigger
Lowanna is like the strawberry for giants. They can grow to about 30cm high and 30cm wide in comparison to a normal strawberry that will grow to about 15cm high. The fruit is also bigger than normal as the Plant growth is concentrated on fruit production rather than runner production (this means not as many baby strawberry plants). These are Australian Bred Strawberries that will grow in all zones. One of the best things about Strawberry 'Lowanna' is day neutral which means it fruits throughout the year (whenever the temperate is between 20-30C). So this means Strawberry 'Lowanna' can crop from October all the way through to late May normally.
