Site selection- Select a site for your Blueberry plants that has full sun most of the day for best results. For climates with high summer temperatures with multiple days over 36°C move the pots to where the plants have protection from the hot afternoon sun.
For best results PlantNet recommends that Blueberry Burst® be grown in a pot or tub( 50 cm minimum diameter) as this gives you more control over the pH, and provides good drainage to help control potential root disease often found in garden soil.
Planting -Remove the Blueberry Burst plant from the original pot you purchased it in within two weeks from purchase. For the most optimum potting mix for your Blueberry Burst, combine 50% course pine bark(10- 25mm in size) with 50% of a premium quality Camellia/ Azalea potting mix . This provides a well aerated potting mix which will extend the life of your Blueberry Burst in a pot considerably. Do not tease the roots of the plant before planting as this will severely affect the plants establishment. When planting your Blueberry Burst into a new larger pot ensure the top of the potting mix remains at the level it was in the pot you purchased. Add a layer of pine bark to the top of the pot to protect the surface roots and minimise moisture loss from the potting mix.
Why Premium potting mix?
Premium potting mixes are the first choice when you want the very best for your plants. They have a greater water-holding capacity, contain added nitrogen and other plant nutrients, and remain at peak performance for a longer period compared to cheaper alternatives. They are a worthwhile investment, especially for those superior plants which you need to keep looking spectacular as decorative specimens.

While blueberries require a pH of 5.0- 5.5 most Camellia/Azalea potting mixes are already in this range. A pH soil test kit purchased from your nearest garden centre or hardware store is easy to use and is ideal for checking soil pH over your entire garden area. Add a good quality 3 month slow release fertiliser to your potting mix and mix in well. PlantNet recommends these potting mixes to help keep the pH low/acid and to provide a well drained and open potting mix for good blueberry root development. Blueberries produce masses of fine roots which mat together when growing well. Without a well aerated potting mix all Blueberry varieties will only have a life of around 2-3 years in pots. This premium potting mix should extend the plants life well beyond this.
Fertilising -Use a good 3 month slow release or organic fertilizer such as composted cow manure every 3 months and add a good liquid fertilizer with added trace elements every fortnight throughout the growing season. For plants 6 months and older applying half a teaspoon of Potassium Sulphate to the potting mix once a month throughout the year to assist with fruit size. For fruiting plants the addition of a half a teaspoon of super phosphate every 6 months will also strengthen root growth. Foliar applications of a good seaweed solution every week from flowering will also improve fruit size. It is important to maintain optimum plant health for best results.
Watering - Because the potting mix is free draining, in warm weather plants should be watered every 2 days or more frequently if required until water just drains out of the pot base. Do not over water! Avoid watering plants over their foliage, as this will help promote conditions for fungal leaf diseases. (Foliar fertilizing while the flowers and fruit is on is the only exception).
Pests and Disease's-All Blueberry varieties are susceptible to fungal leaf diseases(particularly Blueberry Rust) under high humidity and high rainfall. Apply a good fungicide for protection. We recommend Copper Hydroxide (product names include Kocide or Blueshield). Do not wait for leaf damage to occur before spraying, as protection is better than cure. Monitor for scale insects (the first sign of scale activity is ants in the bush , as ants foster scales). Pour a small amount of soapy water onto the affected area only and control ants.
Check for caterpillar damage on a regular basis and control when necessary.
Birds and Flying foxes - Cover with netting as soon as young berries appear on the bush.
Blueberry Burst is an evergreen blueberry variety. A good, strong, healthy plant with foliage free from disease is very important in achieving beautiful large fruit. Do not allow plants to lose their leaves from poor nutrition or disease.
