Orchid leaves talk to you , but you have to pay close care and listen cautiously . foliage betoken overall plant health , nutritional condition and even the comportment of dangerous pathogens . But simple folio harm can occur from inappropriate or rough handling of an orchid works . Careless or unlawful packing can lead in foliage damage during transit . orchidaceous plant unwrap to too much sunlight can easily sustain burns on their leafage . Whatever the reason , the damage helping of a leaf will cursorily conk and turn dark brown or ignominious , and feel teetotal and papery to your touch . The damage will stay altogether localized , and wo n’t diffuse or progress until pathogen enter the plant through the untreated harm . infection and junior-grade disease facilitated by leaf damage will maim or kill your orchidaceous plant . You ’ll need to represent quickly and remove the damage plane section before it ’s too late .
Step 1
Examine the affected leaf carefully to control that round-eyed leaf terms is the culprit . The discoloring will come along all of a sudden and be localize . This can be well remedied by removing the damage luck .
Step 2
Use a aseptic unexampled single - edge razor blade to remove the damaged domain of the folio . Make a clean , crisp reduce completely across the folio ’s full width through healthy green tissue , directly below the black or dark-brown discoloration . Discard the vane – don’t practice it on another plant .
Step 3
use a good fungicide for orchids to the entire wound according to the promotion didactics .
Step 4
depend for sign of the zodiac of sun damage . The affected leaf will yellow if the plant life receives too much sunlight . Extreme overdoses get actual sunburn , killing overexposed areas of leaves . The deadened spots will be non - progressive and confined to the damaged section .
Step 5
duplicate steps 2 and 3 . It is n’t necessary to remove entirely yellowed leave-taking , just the damaged portions . Discard the leaf blade – don’t use it on another plant .
Step 6
Evaluate the sunburned plant ’s lighting experimental condition and adjust as necessary to forfend recur damage .
Step 7
control for nutritionary deficiencies and pathogens as causes of foliage browning or blackening . The leaf begins to conk and blacken from the backsheesh . discolouration spread out downward toward the plant as leaf death progresses . Then opportunist kingdom Fungi fire and feed on idle and die folio tissue , farm a chickenhearted band between the bushed and healthy portions of the leaf .
Step 8
Remove the discredited surface area of the folio with a sterile new single - edge razor blade . Make a fresh cut well into the healthy green tissue paper , directly below the chickenhearted fungal band adjacent to the black or brownish tip stain .
Step 9
Step 10
Discard the blade – don’t use it on another flora . foot up and ruin the diseased plant material – don’t toss it onto the compost heap . Disinfect your work area to keep spreading disease to other plants .
Tip
Always use a new sterile single - edge razor blade for each orchid plant you have-to doe with or treat . This is the most good direction to forbid the spread head of computer virus from one specimen to another . Orchid viruses are incurable .
Warning
Be very measured when plow razor vane . Do n’t try out to tackle more vigorous project such as contract tough rhizomes with them .
