Cloning, also known as propagation, is not as hard as some folks make it out to be. With healthy plants, good techniques and environmental controls you can easily create many clones with ease. There are many things that can cause clones not to root and by having a clear checklist you can prevent clone loss and improve your technique for your business success. The information discussed below is not the actual steps to physically cutting a clone but things to think about when completing the task.
First you must start with healthy plant stock. Can I repeat, “You must start with healthy plant stock”! If you have mold or plants infested with pests then you will have a very hard time reproducing healthy roots and clones. If you have good Integrated Pest Management (IPM) protocol then you will see how much easier it is to reproduce healthy strong rooted clones. Dirty mother plants are the reason for perpetual pest problems, if you start with dirty mother plants then you can guarantee dirty infested clones. Stop the madness and don’t repeat the cycle…
Secondly, please be clean as possible. You don’t need to have vacuum hoods or take a physical shower to reduce contamination. What you do need to be cognizant of is using clean tools during the workflow process. Scissors, razor blades, or whatever you use for cutting should always be wiped down to clean the surface and disinfect. This simple task gets overlooked so many times and is usually one of the relevant issues for roots not popping on a clone. Dull scissors and razors are easy to replace also so don’t be cheap and spend the few dollars to guarantee you are working with the proper tools that are sharp.
Lastly, your environmental control settings with proper temperature and humidity needs to be precise when cloning. This is where many who attempt to clone fail. Too much humidity in your clone dome can cause water droplets to fall into the center of your clone and collect water to rot out the meristem. You will see yellowing from the center outward once this happens. In contrast, not enough humidity can reduce your success rate of root development since the plant has no other way of water uptake except through its leaves. Running higher temps in the 80 to 90s is great for root production but be cautious of cooler temps as this will slow down roots from growing.
Other cloning tricks…
-Use a heating pad for higher success rate.
-Turkey basters work great to help water your clones while in clone domes.
-Don’t be afraid to cut the leaf tips to allow for more area for water uptake while roots are forming.
