A Citrus Splitzer is a single tree where two different compatible citrus varieties—in this case, a Lemon (e.g., Eureka or Lisbon) and an Orange (e.g., Navel or Valencia)—are expertly grafted onto one hardy rootstock. This compact growing method is perfect for small gardens, courtyards, or large pots, as it allows for dual harvests of different fruits from the space of one tree. It offers ornamental appeal with its glossy, evergreen foliage, fragrant spring blossoms, and colourful fruit ripening at different times.
Care Tips (Crucial for Grafted Plants):
-
Position: Requires full sun (at least 6 hours of direct sun daily) to ensure heavy flowering and successful fruit development for both varieties.
-
The Graft Point: Crucially, never bury the graft unions (the visible joints where the scions meet the rootstock) when planting; they must remain above the soil line.
-
Rootstock Suckers: Vigilantly remove any shoots (suckers) that appear on the trunk below the two graft unions. These shoots belong to the hardy but undesirable rootstock and will starve the productive lemon and orange varieties if left to grow.
-
Watering: Water regularly, especially during establishment, flowering, and fruiting periods. Citrus dislikes drying out completely. Use a good layer of mulch, but keep it away from the trunk.
-
Soil & Feeding: Citrus are heavy feeders. Use a slow-release fertiliser specifically designed for citrus in early spring, mid-summer, and early autumn. Ensure the soil is well-drained.
-
Pruning & Balance: While both sides should be pruned to keep the tree productive, it is essential to prune the more vigorous variety (often the Lemon) more heavily than the less vigorous Orange. This prevents the strong grower from dominating and shading out the weaker one, maintaining a balanced canopy and a dual harvest.
-
Usage: Grow in a pot (at least 50L) for easy access, or plant directly in the ground as a compact feature tree.
