require any grower what the primary grounds of root rot diseases is in their plant and they will tell you it is due to overwatering .
While overwatering may enhance disease development it is not the sole constituent . For any disease to attack a flora , three conditions must be present ; first , the pathogen must be present . Second , the environment must allow for growth of the disease organism and at last , there must be a host flora that is susceptible to an onrush by the pathogen . While over watering is a major contributing ingredient leave a favorable environment for root rot disease development , it can not cause damage to the plant unless the plant is in a weakened condition and therefore susceptible to attack . Anything that contribute to " less than optimal ontogeny " can ensue in a attenuate plant , which is then more susceptible to disease organisms . Two commonly overlooked ingredient to pitiable growth carrying out are under and over fertilization .
What are the signs of under fertilization?Under fertilized plant life not only exhibit dull emergence , but are debile in general and are at an increase risk of both diseases and insect plan of attack . Once attacked , plants will use additional nutrients in its attempt to crusade off the disease . If flora nutrition is not promptly corrected , it can lead to compounding of damage . Under fertilization can be easy correct by the software of water - soluble fertilizer which provides which provides nutrients that are right away useable for plants to use .
How to fix overfertilization?Overfertilization on the other paw can be much harder to slump , especially if the overfertilization is the outcome of high applications of Controlled Release Fertilizer ( CRF ) . Over fertilization damages plants in several different ways . It often leave in very “ leggy ” , soft ontogenesis of plant and high-pitched table salt level from fertilizers can burn delicate root summit . Both of these compromise conditions will lead in subvert plants and increased susceptibleness to disease onrush . If the cause of over fertilisation is from elevated levels of water - soluble fertilizer , the situation can be corrected by leach the growing medium with water to remove excess nutrients and then adjusting the rate of next plant food software to encounter the needs of the plants . Over fertilisation when using CRFs can result from either the presence of too much fertiliser or the plant food releasing faster than expected because of gamy temperatures . In either character , there is no quick solution to removing the excess nutrients . The grower must leach with water on a regular basis to remove the excessive fertilizer as it is release from the fertilizer prill . In general , it is best to apply CRFs at a medium charge per unit for the crop and supplement with piddle soluble fertiliser if additional sustenance is needed .
