ROOT BURN PROBLEM? | Update | Orchid Care | Solution | V151

Fertilizer Burn By Susan Jones The saying "If some is good, more is better" is not necessarily a beneficial approach to fertilizing orchids. Plants will only absorb the amount of mineral nutrients they need, which is determined in part by the amount of light they receive, the temperatures they are grown in and the quantity of water available. Just as with people, too much food can cause serious health problems in orchids — excess mineral salts can build up, which they cannot tolerate. It is a gradual problem, affecting orchids that have been consistently over fertilized or have gone too long without repotting, allowing mineral salts to accumulate and concentrate over time. Lack of root growth may indicate an unhealthy concentration of mineral salts in the medium, on up to full fertilizer burn. If this is suspected, decant the plant and check its roots. Dead root tips, brown roots or salt crust on the potting medium surface are signs of trouble. In later stages, brown leaf tips may appear, indicating burned roots. Leaves, and eventually pseudobulbs on sympodial orchids, can become yellow. If allowed to continue, fertilizer burn will eventually kill the plant. If the damage is done and an orchid injured through over fertilizing, the road to recovery starts with decanting the orchid, removing all of the old medium and thoroughly flushing the roots with plain water to remove accumulated salts. Next, repot the orchid using fresh clean medium and a new pot. Keep the plant shaded and shield it from temperature extremes as you would any recently repotted plant, watering regularly and reintroducing a dilute fertilizer once the plant begins to establish. Feeding Aggressively means giving to much fertilizer to our orchids. This is different from what has been promoting by some expert. #docdheltv #elparaiso #orchidcare
