Growing strawberries for home gardeners
Apart from supplying runners and plug plants to commercial growers, Sweets Strawberry Runners also encourages growing strawberries for home gardeners.
The purpose of this page is to provide the home gardener with as much basic but useful information as possible on how to start your own strawberry patch.
The botanical name of strawberries is Fragaria x Ananassa, from the family of Roses (Rosaceae). Strawberries are short-lived herbaceous perennials, meaning plants can produce for 2-3 years.
However, commercial strawberries are grown for one season and replanted each year to maintain variety purity and yield levels.
Runners are supplied as leaf-on or leaf–off by runner suppliers. Usually leaf-on runners are used by Queensland Growers for autumn planting. Leaf-off is normally used by growers located in the cooler areas where frost is a high risk.
Where to grow Strawberries
Strawberries prefer to be grown in full sun, which means they should be planted in an area that receives at least six hours of sunlight per day.
Additionally, they require well-drained, sandy loam soils with a pH between 5.8 and 6.2. Heavy soils can also be used, but they must be well-prepared and supplemented with a lot of compost or manure.
However, it is important to avoid planting strawberries on patches that have previously grown tomatoes, potatoes, eggplants, or other crops, as they may be at risk of fungal disease called Verticillium Rot.
Hydroponics and pot plantings are also suitable methods for growing strawberries. Refer to the following websites for more information on hydroponics:
What varieties to grow
The following varieties are recommended for the home gardener and are available from Sweets Strawberry Runners. It is very important to get certified disease free plants from certified runner growers or nursery.
- Redlands Joy – fruit is sweet, suitable for warmer subtropical climates, especially in the southeast Queensland corner. High yielding and productive throughout the season and may also be used in pots and hydroponics settings.
- Lowanna – medium dense plant structure and will produce fruit throughout the year being a day neutral variety. This variety is suitable to pots and hydroponics setups. Normally produce fewer runners.
- Sugarbaby – Normally produces large size berries and commence producing fruit around early June. Fruit seem to resist rain damage. Well suited to Queensland conditions. This variety also grows well in pots. Bred by QDPI
- Rubygem – Fruit is an attractive moderately dark glossy red and is medium to large, uniformly shaped and is short conical to slightly wedged.
Strawberries need plenty of water for good fruit production.
However, overwatering may cause too much water to sit in the soil, which may lead to loss of nutrients or cause mould on fruit. 1” – 2” of water per week is needed for juicy fruit and is especially important while the fruit is forming, from early bloom to the end of harvest.
Trickle irrigation is a commonly used method of watering once plants are established to avoid disease such as powdery mildew.
Start with a rich organic soil. Adequate compost and organic manure should give the plants a good start.
However, strawberries need good nutrients to produce continuous good fruit. Fertilisers can be used to add nutrients to the soil. Complete or balanced fertilisers (NPK +trace elements) are good source of nutrients.
After planting, fertiliser may be broadcasted and watered into the soil or mixed in water and watered onto the soil around plants. It is important to add the correct amount of fertiliser as there is a risk of burning the plants when applying too much fertiliser. Calcium and potassium are important for good fruit production.
Maintaining your garden is a must as there are so many pests, diseases, weeds and other undesirables that can be of nuisance to your strawberry plants. Good thick mulch normally reduces incidence of weeds, however any weeds growing along the rows or beds need to be cleared, as they harbour pests and diseases.
It is best to carefully remove any runners that grow from the plants. New runners growing from the plants compete with fruit for the available nutrients. The aim is to produce the best berries that you and your family will enjoy.
Runners are only available from Sweets Strawberry Runners from April to September each year.
