Rev says... I don't know. But I do know you need a balanced NPK fertiliser for good growth. Whether it be organic or inorganic. I grow on my fruit trees in sacks before planting so I can repair their root systems. I grow in a mix of soil and rice hulls, and I give them a heaped teaspoon on 15:15:15 every two weeks. They respond wonderfully. I'm in Asia. Your materials will vary but the concept is the same. Balanced fertiliser, less but more often. | About the Author Rev TABULAM,2469,NSW 27th September 2016 9:41am #UserID: 1806 Posts: 359 View All Rev 's Edible Fruit Trees |

health101orgarticles1 says... What's "e;15:15:15"e;? The NPK fertilizers are relatively new and artificial/synthetic and which only have three minerals. Plants need way more than just 3 minerals. That makes them a very unbalanced fertilizer. I think that certified organic food is grown with no NPK ie artificial fertilizers. They probably use certified organic fertilizers that have NPK and the other 100 other minerals only. I think that plants need just enough fertilizer and frequently enough to grow the most fruit that the grower wants. I don't understand why you have young trees in sacks hung in trees and your need to repair root systems. | About the Author health101orgarticles1 EAST BRISBANE,4169,QLD 1st October 2016 6:49pm #UserID: 316 Posts: 159 View All health101orgarticles1's Edible Fruit Trees |

Manfred says... I think you are misunderstanding the reference to NPK. It isn't an artificial substance called NPK, but a reference to the amounts of nitrogen (N), phosphorous (P) and potassium (K). So 15:15:15 NPK is 15& of each, with rest (55%) being either minor components, or, more likely oxygen, as in NO3, PO4, or hydrogen as in NH4. Sometimes the remainder will include stuff like sulphur and sometimes a near-useless component like chlorine. NPK tells you what the main characteristics of the fertiliser is, so for leaf growth go for high N, for flowers and fruit, high P and K. Non NPK fertilisers like potassium sulphate or ammonium nitrate don't quote an NPK ratio. | About the Author Manfred Wamboin 21st February 2017 1:34pm #UserID: 9565 Posts: 243 View All Manfred's Edible Fruit Trees |
