i was so excited to hear that instructables opend a gardening contest because i study plants and do expirements on them to find new,clean and good for the enviroment fertilizers and other products used to cultivate plants,
i'm going to show you how to heal plants stem or trunk for free. i found that most people choose to put a speacial tar on the damaged trunk of trees to prevent rotting yet i discovered that doing this dosent allow the trunk to breath and it also makes mold and rotting of the trunk, but if you dont put it on it will also rot so what do you do? i got the solution! take a pice of aloe vera and cut/fellet like shown, take the piece of aleo vera and chop on a cuting board, NOT WOODEN! now put in a zip block and squish the aleo into a thick liquid consistency. set aside, now take 1 tablespoon of cornstarch and set aside, now you can take the ziplock and turn it in-side-out over a bowel and scrape the remains into the bowel.NOTE: make just enough to cover the wound. now you can add the cornstarch you may need to add a little mor for bigger batch but i dont think you need any more then i showed. mix it together with a MEDAL spoon. now using the spoon rup on the wound, this creates a bandage like thing, kinda the way a scab works, it will heal and protect the wound and also the plant will soak up the substance puting it into its systm, this tequnique will make sure you have more plants each year.
to store left over put in a titely secured container in the fridge for only about five days....if you want to save in longer put it in the frezer then when you want to use it put it in the microwave for about 30 seconds then use a spoon to squish it to the right consistency.
