Foliar mineral fertilizers (commercial)<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">These are easy to apply and have balanced compositions. Here are some popular recommendations on the Romanian market:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>After planting or transplanting seedlings:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Kristalon Yellow (Yara)<\/strong>\u00a0\u2013 13-40-13, ideal for root development<\/li>\n\n\n\n<li><strong>Plantafol 10.54.10 (Valagro)<\/strong><\/li>\n\n\n\n<li><strong>Agromaster Start 13-40-13 (Compo Expert)<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>During the fruit formation period:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Kristalon Orange<\/strong>\u00a0\u2013 6-12-36, supports fruiting<\/li>\n\n\n\n<li><strong>Plantafol 5.15.45<\/strong><\/li>\n\n\n\n<li><strong>Agromaster 3-11-38 + microelements<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Maintenance fertilization (every 2-3 weeks):<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Aminofeed (Agro-CS)<\/strong>\u00a0\u2013 contains amino acids + microelements<\/li>\n\n\n\n<li><strong>Agricola Vegeta (Fertillia)<\/strong>\u00a0\u2013 with balanced macro and microelements<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Natural products you can make at home<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Alternating chemical fertilizers with natural ones is beneficial. Here are some simple recipes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Nettle maceration:<\/strong><br>Put fresh nettles in a barrel of water (chlorine-free), leave for 7 days, stir daily. Dilute 1:10 and spray. It is rich in nitrogen and stimulates growth.<\/li>\n\n\n\n<li><strong>Compost\/vermicompost tea (wormwood humus):<\/strong><br>1 kg of humus + 10 liters of water, left for 6-12 hours. Can be used undiluted.<\/li>\n\n\n\n<li><strong>Onion peel infusion:<\/strong><br>2 cups of peel + 500 ml of hot water, leave for 24 hours, make up to 3 liters. It has an antifungal and fertilizing effect.<\/li>\n\n\n\n<li><strong>Infusion of clean wood ash:<\/strong><br>1 cup of ash + 1 liter of hot water, left for 24 hours, then topped up to 10 liters. Very rich in potassium and calcium \u2013 perfect in the second half of the season.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Calcium fertilizers \u2013 against apical rot<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Calcium deficiency is seen through black spots on the top of the fruit (apical rot). Solution:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Calcium nitrate (e.g. Calcinite from Yara)<\/strong>\u00a0\u2013 15 g per 10 liters of water.<br>Apply 1-2 times per season, during the flowering and beginning of fruiting phase.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Boron \u2013 for more fruit set<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Boron deficiency = flowers that do not set fruit.
