Its success is also due to its ease of cultivation, low maintenance compared to other varieties, and its excellent taste.
Planting and propagating the Royal Gala apple tree
- Multiplication: By grafting, the most effective method to maintain varietal characteristics
- Optimal planting time: Preferably in autumn, adjusting according to weather conditions to avoid early frosts and ensure the plant roots effectively.
- Ideal substrate: Fertile, deep, and well-drained soils with a pH between 6,0 and 7,0. It is important to avoid waterlogged or excessively calcareous soils.
For optimal rooting, it is recommended to dig wide holes and prepare the mixture beforehand with organic matter and wood ash, facilitating nutrient absorption and preventing deficiencies during the rooting phase.
Royal Gala apple tree care: key aspects
Lighting and exposure
The Royal Gala apple tree needs plenty of direct sunlight, with at least 6 hours of sun per day recommended for optimal growth and fruit quality. It is vital to place the tree in open spaces, away from other large plants or structures, and to ensure good air circulation, which helps prevent fungal growth.
Climate and temperature
It grows best in cool to temperate climates, although it can withstand harsh winters if it has a sufficient winter dormancy period (around 800 chill hours at temperatures below 7°C). It can tolerate sharp temperature drops for short periods, but late frosts , especially during flowering, can damage the crop. Planting late-flowering varieties is recommended in areas prone to spring frosts.
Irrigation
The Royal Gala variety requires regular watering during the first few years after planting, especially during periods of drought or intense heat. Once established, watering can be more moderate, increasing only during very dry summers. Excess water is counterproductive as it reduces the sugar content of the apples and can promote root diseases; therefore, drip irrigation is the most efficient and reliable system.
Pruning and training
Annual pruning is essential . It should ideally be done at the end of winter, when the plant is dormant. Remove any dead, diseased, or unproductive branches and thin out the interior to allow more light to penetrate. It's advisable to trim the top of the main shoot during the first few years to encourage the development of a balanced and regular canopy. Thinning the fruit after flowering also helps improve the size and quality of the final harvest.
Fertilization and fertilization
- Potted: Use liquid universal fertilizer monthly, and make at least one contribution of organic fertilizer per year
- On ground: Incorporate organic matter in spring, along with mineral fertilizers rich in nitrogen, phosphorus, and potassium; a second application of phosphorus and potassium in autumn before the vegetation stops.
The level of fertilization will depend on the rootstock and the vigor of the tree, with dwarf rootstocks requiring more fertile soil and intensive care.
Pollination and thinning: Maximizing production
The Royal Gala apple tree is not self-fertile ; therefore, it requires a complementary variety for cross-pollination. It is recommended to plant at least two trees of different varieties that bloom during the same period to ensure maximum fruit set. The use of beehives or other natural pollinators in commercial orchards is key to improving fertility and crop quality.
- The optimal fruit setting rate is around 10-30%.
- Natural thinning usually occurs after flowering, but in abundant harvests it may be necessary to manually remove small or misshapen fruits and space them every 10-15 cm to avoid competition and improve size and flavor.
Transplanting and adapting to different spaces
- Transplanting rooted trees: Performed during the winter rest state
- Transplanting from pot to soil: It can be done at any time, except in periods of extreme cold or heat.
For intensive cultivation techniques or small gardens, there are dwarfing rootstocks such as M9 or M27 that allow the cultivation of small apple trees, ideal for espaliers or pots.
Harvesting, storage and uses of the fruit
Royal Gala apples are typically harvested in late summer or early autumn, depending on the region. Harvesting them at their peak ripeness is crucial to ensure maximum quality and shelf life. Royal Gala apples keep exceptionally well in cool, well-ventilated areas and can last for weeks or months if properly stored in wooden crates, wrapped in paper, or in perforated plastic bags.
- Early varieties should be consumed soon after harvest.
- Late varieties like Royal Gala can be stored for longer periods, retaining texture and flavor.
Its main uses include fresh consumption and the production of juices, desserts, compotes, and jams. It is also a common ingredient in salads, pastries, and, to a lesser extent, in the juice and cider industry.
Common pests and diseases of the Royal Gala apple tree
- Powdery mildew: Fungal disease that affects leaves and shoots, prevented with preventive treatments and aeration control.
- Crust: It produces spots on leaves and fruits, requires monitoring and treatment with specific fungicides.
- Aphids: They suck the sap from young shoots, weakening the plant and transmitting viruses.
- Mealybugs: Parasites that attach themselves to branches and fruits
- Caterpillars and moths: They attack the interior of the fruit, making it necessary to use pheromones or natural treatments such as infusions of garlic, wormwood and tomato paste.
- Weevil: It affects flowers and reduces fruit setting.
- Black and root cancer: Fungal and bacterial diseases affecting trunk and roots, aggravated by physical damage or poorly drained soils
Prevention is key , achieved through pruning to improve air circulation, removal of fallen leaves, and preventative treatments with mixtures of fungicides, insecticides, and foliar fertilizers. For pests, biological control and the use of traps or physical barriers are very effective, avoiding the excessive use of chemical products.
Physiological diseases and ecological management
Excessive humidity, waterlogged soils, or insufficient fertilizers cause problems such as fruit cracking, premature fruit drop, or poor storage. In organic farming, the use of natural preparations, crop rotation, and combinations with repellent plants are prioritized to reduce pest pressure. Soil pH control and balanced nutrition are effective strategies against physiological problems.
