Position
Full sunlight helps to prevent the tree from contracting diseases. The sunshine also helps with producing sweet, delicious fruits. Nectarine trees, a type of stone fruit, require cold winters.
Allow it about 6 metres of space to grow without being hindered. Use companion plants like legumes, as they attract the right pollinators and help keep the soil fertile.
Size
This tree reaches a mature height of about 5 metres and its canopy has a width of 2.5 to 3.5 metres.
Soil Type
Soils that are well-draining yet still retain some moisture are best suited for nectarine trees. The only soils that do not work well are those that are very dense or heavy. A slightly acidic pH, ranging from 6.0 to 7.0, is ideal for fruit trees.
Watering
Water your nectarine tree once every 10 to 14 days, ensuring it is thoroughly soaked. Be careful not to overwater it, though. Even if the surrounding grass is brown and dry, the nectarine tree can still thrive on this amount of watering.
Mulching
Apply organic mulch to your nectarine tree throughout the year.
Use from 2 to 5 centimetres of pine bark mulch to protect the roots from UV damage and drying out. It retains moisture and maintains an optimal pH. Do not let the mulch touch the plant stem, as it may cause infection or rot.
Fertilising
Use our slow-release nitrogen-rich all plant fertiliser. Apply 1 teaspoon every 4-5 months.
Pruning
Pruning is essential for maintaining the shape and promoting airflow, which helps prevent diseases.
For young trees, establish a strong framework; for mature trees, maintain the desired shape. When making cuts, cut back to a healthy bud and at a slight angle to promote healing. If the tree is getting too tall or wide, prune it to maintain a manageable size.
Pests and Diseases
Aphids, citrus psylla, red scale, citrus greening. Spraying regularly with Agricultural Neem Oil or Effective Microorganisms (EM Control) will assist in either prevention or after the fact. If you already have aphids or mites, wash the tree with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Practice good garden hygiene (remove fallen fruit and leaves).
Watch for root rot (caused by overwatering) and fungal infections during wet periods.
Thinning
Thinning fruit on nectarine trees is essential for producing healthy, high-quality fruit. When trees produce too much fruit, they can become stressed, resulting in smaller, weaker fruits that are more susceptible to disease.
Thin the fruit in late spring to early summer, when the fruit is marble-sized. Avoid thinning too early to prevent unnecessary fruit drop.
Focus on removing smaller or poorly positioned fruits, especially those clustered together, leaving approximately 10 to 15 cm of space between each nectarine. Also, remove any fruit showing signs of pests or disease to prevent the spread of issues.
Harvesting
Pluck your scrumptious, sweet fruit when the skin is the right orange-red colour and the flesh is soft close to the stalk.
