The Apple tree belongs to the Rosaceae family, species Malus Pumila. Malus pumila is a deciduous tree growing up to 5 metres tall in cultivation and up to 9 metres tall in the wildIt has a life time of about 60-80 years. It is one of the most widely cultivated fruit trees in temperate regions of the world, growing in over 93 countries. Selection over thousands of years has produced an enormous diversity of apple cultivars varying in shape, colour, sweetness, crispness and storability. Red Delicious, Golden Delicious, Braeburn, Cox, Pink Lady, Royal Gala and Bramley represent just a few apple varieties found in supermarkets in temperate countries.

Climate: It is more resistant to cold than the pear tree and does not need so much heat and light for ripening. It suffers less with the cold than with the heat and prefers humid to dry climates. The flowers are sensitive to late spring frosts, the use of anti-freeze irrigation or other protection systems are common in areas with high risk. The apple tree tolerates temperatures lower than -10ºC, without affecting the tree bark, although when descending below -15ºC some floral buds may be lost.

SoilThe apple tree is not demanding in terms of soil but it needs well drained soils. The best crops are found on fertile sandy and loamy soils.

pH: 5.5-7

The Pear tree belongs to the Rosaceae family, genus Pyrus. The pear is native to coastal and mildly temperate regions from Europe to Western Asia. It is a medium-sized tree, reaching 10–17 metres tall, often with a tall, narrow crown; a few species are shrubby.

ClimateIt grows well in temperate and somewhat humid climates, being more resistant to cold than to heat. The most suitable climate is characterized by winters with sufficient winter cold, few frost and late spring and sunny summers with temperatures not very high, although the existing varietal range allows their cultivation in different climates within the temperate zone.

Soil: This fruit tree is demanding in terms of soil. It only grows well in loamy-clay and siliceous soils, healthy and permeable soils. It requires homogeneous and deep soils, neither too dry nor too humid. 

pH: 6.5-7.5

Foliar fertilizers

Foliar fertilization is the fastest and most effective method to supplement and enrich plant nutrition and to correct nutritional deficiencies when needed. This contributes significantly to higher and better quality productions.

Calcium, Boron, Zinc and other micronutrients are also applied via foliar. Lima Europe has a wide range of foliar fertilizers and special products for foliar application.

To verify the safe rate under local conditions, it is advisable to spray recommended rate on a few plants. After 3-4 days check the tested plants for scorching symptoms.

 

Apple/Pear fertilizer program

 

5 NPK Multi 20-20-20 + 6 CaO + 3 MgO + TE

5 NPK Fructus 18-9-36 + 6 CaO + 3 MgO +TE

Grogreen Ca/B: 2-5 kg/ha. In order to correct Ca and Boron deficiency. Ca/B increases flowering and fruit set

Calciphos: 2-5 kg/ha from flowering to maturity

Zn E-15: 1 kg/ha for foliar application. In order to correct possible deficiency

proteKt-K50: 2 l/ha. For a supplement of K at fruit development stage

Pro-mino: 200-300 ml/hl
