How does fertiliser work in the plant's physiological cycle?\u003c\/h4\u003e\u003cp\u003eLiquid fertilisers such as the products in the GREEN24 PROFI LINIE supply essential nutrients directly in a form that plants can use. Their main ingredients are nitrogen, phosphorus and potassium, often supplemented with micronutrients and chelates. These nutrients are necessary for photosynthesis, cell division and general plant health. Nitrogen primarily promotes leaf growth, phosphorus supports root development and flower formation, while potassium increases overall plant strength and disease resistance.\u003c\/p\u003e\u003ch4\u003e2. Which GREEN24 growing medium can be used?\u003c\/h4\u003e\u003cp\u003eThe GREEN24 professional growing medium for fruit trees is recommended for pear trees. This growing medium is optimally tailored to the needs of fruiting plants, providing excellent drainage while retaining sufficient moisture.\u003c\/p\u003e\u003ch4\u003e3. How and when should the plant be repotted?\u003c\/h4\u003e\u003cp\u003ePyrus communis should be repotted in spring, before the growing season begins. Choose a larger pot or container and use the GREEN24 growing medium mentioned above. Carefully remove the old soil from the roots, trim off damaged roots and place the plant in the new soil.\u003c\/p\u003e\u003ch4\u003e4. When is the growing season?\u003c\/h4\u003e\u003cp\u003eThe pear tree's growing season begins in spring and continues until autumn, approximately from March to October. This is its main growth phase, when feeding should also be more intensive.\u003c\/p\u003e\u003ch4\u003e5. Which position is best?\u003c\/h4\u003e\u003cp\u003eThe pear tree prefers a sunny to partially shaded position. A place with plenty of light that is also sheltered from strong winds is ideal.\u003c\/p\u003e\u003ch4\u003e6. What should you bear in mind when growing it in a pot or container?\u003c\/h4\u003e\u003cp\u003eWhen growing in a pot or container, sufficient drainage is important to prevent waterlogging. Choose a pot with drainage holes and use a drainage layer of gravel or broken terracotta. Regular watering is necessary, particularly during the hot summer months, but avoid standing water.\u003c\/p\u003e\u003ch4\u003e7. When and how should the tree be pruned?\u003c\/h4\u003e\u003cp\u003eRegular pruning should take place in late winter or early spring before new growth begins. Remove dead, damaged or crossing branches and maintain an open crown that lets light through easily.\u003c\/p\u003e\u003ch4\u003e8. Flowering and fruit formation\u003c\/h4\u003e\u003cp\u003eThe pear tree flowers in spring, producing white flowers with five petals. After pollination, the fruits develop in early summer and ripen by autumn. Careful maintenance, such as feeding and pruning, can encourage fruit formation.\u003c\/p\u003e\u003ch4\u003e9. Varieties and colours\u003c\/h4\u003e\u003cp\u003eThere are many varieties of Pyrus communis, differing in the size, flavour and colour of their fruit. Well-known varieties include 'Williams Christ', 'Conference' and 'Alexander Lucas'. Colours range from green to yellowish-green and reddish tones.\u003c\/p\u003e\u003ch4\u003e10. Pests and diseases\u003c\/h4\u003e\u003cp\u003eCommon pests include aphids, pear suckers and pear rust. The most common diseases include fire blight, scab and powdery mildew.\u003c\/p\u003e\u003ch4\u003e11. Active ingredients against pests and diseases \u003c\/h4\u003e\u003cp\u003eControl products can include neem oil against aphids and systemic fungicides against scab. Copper preparations can be used against fire blight.\u003c\/p\u003e\u003ch4\u003e12. Home remedies for care and protection\u003c\/h4\u003e\u003cp\u003eA solution of water and soft soap can be used to control aphids. Nettle liquid manure can also strengthen general plant health and deter various pests.\u003c\/p\u003e\u003ch4\u003e13. How foliar feeding and soil feeding work.\u003c\/h4\u003e\u003cp\u003eWith foliar feeding, nutrients are sprayed directly onto the leaves, where they are absorbed quickly and can act rapidly. Soil feeding, on the other hand, supplies nutrients through the root system, providing a longer-lasting, continuous source of nutrition. The two methods complement each other optimally and ensure a comprehensive supply of nutrients to the pear tree.\u003c\/p\u003e\u003cp\u003eWith the right care and high-quality GREEN24 products, you can ensure that your pear tree grows healthily and produces abundant, beautiful fruit.\u003c\/p\u003e\n\u003cp\u003ePlease note: The label is generally only available in German.\u003c\/p\u003e\n","brand":"GREEN24","offers":[{"title":"250 ml","offer_id":58871798825344,"sku":"BBA20N75K25","price":9.85,"currency_code":"EUR","in_stock":true},{"title":"500 ml – twin pack (2 × 250 ml)","offer_id":58896393732480,"sku":"BBA20N75K25-2x250","price":18.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/2868\/5696\/files\/green24-3413_1.webp?v=1788679827","url":"https:\/\/www.green24.de\/en\/products\/birnbaum-duenger-250ml","provider":"GREEN24","version":"1.0","type":"link"}
