Plum Omega
Plum Omega
Plum 'Omega' is a highly regarded Japanese plum that produces generous crops of large, dark purple fruit with juicy, deep red flesh and an outstanding sweet flavour. Ripening late in the season, Omega is an excellent choice for extending your plum harvest and is equally delicious eaten fresh or used in cooking, bottling and preserves.
In early spring, the tree is covered in masses of delicate white blossom that attracts bees and other pollinators, making it both a productive fruit tree and an attractive ornamental feature. Vigorous, reliable and easy to grow, Omega is well suited to home orchards throughout New Zealand.
Plum Omega is not reliably self-fertile and performs best when planted with a compatible Japanese plum variety.
Excellent pollination partners include:
- Black Doris
- Santa Rosa
- Duff's Early Jewel
- Elephant Heart
Cross-pollination will improve fruit set, increase crop size and produce more consistent harvests.

How to establish your Plum Omega?
How to establish your Plum Omega?
Plant Plum Omega in a full sun position.
For best results:
Choose a site with at least six hours of direct sunlight daily.
Protect young trees from strong prevailing winds.
Allow plenty of airflow around the canopy to reduce disease pressure.
How to maintain your Plum Omega once established?
How to maintain your Plum Omega once established?
Water deeply once or twice each week during the first growing season.
Once established, water regularly during prolonged dry periods, particularly while fruit is developing.
Consistent moisture helps produce larger, juicier fruit.
For healthy growth and reliable crops:
Apply compost annually in spring.
Feed with a balanced fruit tree fertiliser before new growth begins.
Avoid excessive nitrogen, which encourages leafy growth over fruit production.
Plum trees should be pruned in summer after harvest, rather than winter, to reduce the risk of silver leaf disease.
Remove:
Dead or damaged branches.
Crossing branches.
Upright water shoots.
Crowded growth within the canopy.
Maintaining an open framework improves airflow, sunlight penetration and fruit quality.
If your tree sets a heavy crop:
Thin fruit after natural fruit drop.
Leave plums spaced approximately 5–10cm apart.
This produces larger fruit and helps prevent branches from breaking under heavy loads.
Harvest Omega when:
The fruit develops a deep purple skin.
It gives slightly when gently squeezed.
The fruit separates easily from the stem.
Pick regularly as fruit ripens for the best flavour.
Omega is well suited to New Zealand's temperate climate.
To keep your tree performing at its best:
Apply mulch around the root zone while keeping it clear of the trunk.
Protect blossom from severe late spring frosts where possible.
Ensure the tree receives adequate winter chilling for reliable flowering and fruit production.
Monitor for common stone fruit pests and diseases such as:
Aphids
Brown rot
Leaf curl
Scale insects
Good pruning, orchard hygiene and airflow help minimise disease problems.
