There are many synthetic rooting hormones available including liquids, powders, and gels that can promote rapid root growth in olive tree cuttings. But if you an organic gardener or you just prefer natural products, as an alternative to commercial hormones, you can also use common household ingredients and make your own homemade natural rooting hormones for olive trees to aid rooting and act as natural rooting stimulants.
Furthermore, if you are concerned about the chemicals found in the synthesized hormones and you are not willing to buy one, then search stuff at home and use what you have from the following ingredients:
- Aloe vera gel
- Apple cider vinegar
- Willow water
These ingredients are naturally antibacterial, antiseptic, and antifungal rooting hormones and may help to prevent fungus and or bacteria from destroying the cutting before it has had enough time to root and ensure faster growth.
To make it crystal clear, I will explain how to use each of these ingredients that can increase the success of your olive tree cuttings to root with these homemade rooting hormones.
1. Aloe Vera Gel
If you have aloe plants growing around your house, you can use the freshly squeezed aloe vera gel, as well named as an extract, to make your own homemade natural rooting hormone instead of commercially available to propagate cuttings with success.
Research studies show, that aloe vera works as a potential growth enhancer and protects the olive tree cuttings from bacteria and fungi from entering the stem. These natural plant extracts are a cost-effective and environmental friendly alternative to synthetic plant growth regulators and phytohormones.
Aloe vera’s active ingredient salicylic acid is an anti-inflammatory element and rooting stimulant. The same key component is found in the homemade rooting hormones as #5 aspirin and #6 willow tea described below.
