At times cactus plants receive wounds , either from deed of nature like hailstorm , stroke with twine trimmers , gnawing animal , or from routine care such as transplant or take cuttings . To best assist your cactus survive and heal , you need to know cactus first aid . Factors that square off how fast the combat injury will bring around bet on how wide and deep the wound is and where it is located . The main destination is to prevent infection until the cactus forms a scab .
Step 1
Cacti are lush plants that lay in water in their stems and often in their tooth root . They protect themselves with a problematical wax - covered cuticle to lessen water loss as well as a spine covering to shade the skin and discourage herbivores . However , if trauma expose moist intragroup tissues , naturally go on pathogens such as bacteria and fungi can feed on the salt away food and moisture . If the wound is keep dry , some cacti cope by release a worthless polyose that coat the wound and prohibitionist into a waterproof layer . Others form a tough corky stratum over the wound . It can take weeks or months to complete the summons . If the injury is approximate or in the dirt , or humid weather or pelting occurs , the chance of contagion goes up . If contagion occurs , the wound begins to rot , with pathogen finally broadcast through the entire plant .
Step 2
Shallow Surface Wounds
Shallow wounding result from the snick of a hoe , a string trimmer slice , or a scrape should be treated instantly . Treat and disinfect the wounding with atomic number 1 hydrogen peroxide or dust it with horticultural sulfur or purge pulverisation comprise bleach . Do n’t water the lesion area and protect it from rain . Shallow wounding normally cure in a workweek or less in summertime , longer in wintertime . Inspect your cacti occasionally to monitor chewing hurt from wildlife , commoner in drouth long time , protecting the plants with fence if necessary and care for the wound .
Deep Wounds
Sometimes wildlife can make deeper wound , such as pocket gopher digging up from the bottom of the plant , or rabbits chewing the sides . Clean and disinfect the combat injury , removing any dirt or start out pockets of rotting . All the tissue paper exposed should front white and clean . It will take longer for deep or extensive wounds to bring around , often week or month in nerveless weather . For a deep puncture wound , excise any damage tissue paper around the puncture and to debunk the extent of the wound so air can extend to the bottom . Disinfect and see for healing , which will be slower because less aerofoil area is exposed to free gentle wind drive . When you take a bow thinning of a columnar cactus for root , make a slanting snub so water does n’t model on the cut surface of the female parent industrial plant . A orotund diameter cut can take several months to heal .
Wounds From Transplanting or Propagating
radical wounds also need to be healed . When you fag up a cactus for relocation , use a sharp shovelful and turn over around the plant life for about a foot , flawlessly severing the ascendant you encounter . Then dig under the plant life , levering it up so you may cut or cleanly burst deeper roots . Shake off the ground and move the plant into the ghost , where you could cleanly recut all broken roots and disperse them with horticultural sulphur or rooting hormone containing fungicide . Allow beginning terminate to heal before replanting the cactus , which should take a few days to several week in strong weather , depending on the diameter of the wounds . It takes longer to bring around wounding in cool weather or if the plant is inactive .
