Nectarine Nectarella Tree
Nectarella is a self-fertile[1] [2], genetic dwarf [5] nectarine tree grown for quality, sweet orange-red flesh and freestone fruit on a compact, very slow-growing tree. [1] It is one of the best choices if you want a nectarine tree for a patio, a large pot or a small garden where a normal fruit tree would take up too much room.
Nectarella is grown on St Julien A rootstock, but being a genetic dwarf, has an expected final height of around 200cm.
Expect pink blossom in March followed by juicy, sweet fruit with a red blush [2] picked around early August. [1] [2] In practice, ripening will depend on the growing position, weather and how much warmth the tree gets. For larger crops, use hand pollination, especially if the bees and other buzzies are not coming out to play at the time of flowering.
Nectarella’s naturally dwarf, slow-growing habit means fruiting from a young age may be possible if the tree is well grown, well positioned and properly cared for, but early fruit should be treated as a bonus rather than a promise. RHS says fruit on dwarfing rootstock can begin within two years, although this is general fruit-tree guidance rather than a Nectarella guarantee. [7]
Pot growing gives Nectarella a practical advantage over planted peach trees and nectarine trees. Growing it in a pot makes it very easy to protect under cover in spring from peach leaf curl disease. [1] It can also be moved to make better use of sun and shelter.
Peach Leaf Curl
Peach leaf curl is common and is caused by the fungus Taphrina deformans. It causes severe leaf distortion soon after leaf burst in spring. [4] It is not just a cosmetic problem because it can reduce the tree’s ability to grow, flower and set fruit. [8] The fungus survives on the tree, including around buds, bark and shoots, and is spread during wet weather as the buds begin to open. Infection is most likely in cool, wet conditions in late winter and spring, so the problem is often worse on trees left exposed to rain during bud burst.
The best protection is to keep the tree buds and young leaves as dry as possible during January to May. A pot-grown Nectarella can be moved under cover or placed in a sheltered spot where rain cannot wet the opening buds and young leaves. Good airflow still matters, and the tree should not be kept wet, cramped or waterlogged. Once the leaves are fully open and the weather is warmer and drier, the main infection risk is usually much lower.
Planting a Nectarine Nectarella Tree
Plant Nectarella in the sunniest, warmest and most sheltered position you can offer. A sunny patio, sheltered courtyard, greenhouse doorway area, or warm wall-side position is usually more suitable than a cold, exposed or shaded part of the garden.
Nectarella is especially useful for pot growing. [1] Use a large, stable container rather than a small decorative tub. RHS recommends containers at least 45cm / 18in wide and deep for compact nectarines, filled with peat-free soil-based compost. [3] The larger you make the pot, the more you support the tree.
Before planting, water the pot well. Plant at the same depth the tree was growing in its original container, firm the compost or soil gently around the roots, and water thoroughly after planting.
Keep the tree watered while it establishes and do not let a container-grown tree dry out during the growing season. RHS fruit-container guidance says to let the compost surface start to dry before watering again, without letting it become bone dry. [9]
Protect the blossom from frost where possible. RHS general nectarine guidance recommends protecting flowers from frost with horticultural fleece. [3] This matters because blossom damage can reduce or ruin the crop before the fruit has even started.
Other Interesting Information About Nectarine Nectarella Trees
Nectarella was bred in California. [1] That helps explain why it wants warmth and sun, but its dwarf habit makes it much more practical for UK gardeners who can offer a sheltered patio, large pot or protected growing spot.
Nectarella also appears in official European variety records under the name Zaidulab. The Hungarian National Fruit Variety List records Zaidulab under Prunus persica, gives the origin as US, and lists Nectarella as the synonym. [6]
