Auxin, a naturally occurring plant hormone, stimulates root formation. Several synthetic forms of auxin are sold as “rooting hormone.” Though some plants will root readily without treatment, application of rooting hormone to the base of the cutting will often improve your chance for success.
For semi-quick use: Take one young willow shoot, removing any leaves, and cut it into 1-2'' pieces. Half-fill a quart-sized mason jar with the pieces and fill the jar with cool or tepid water. Let sit for 5-7 days, then strain and compost the willow pieces. The willow water root stimulant is now ready for use.
Pothos release a natural rooting hormone into the water that helps trigger root growth in other cuttings sharing the same water.
For plant roots to grow faster, it requires nutrients, sufficient water, well-aerated soil, enough light, the right range of temperature and proper amendments.
Encouraging Root Formation
A mixture of 50% vermiculite/50% perlite holds sufficient air and water to support good root growth, but any well-drained soilless potting mix is acceptable. If your cuttings frequently rot before they root, you know the mix is staying too wet.
Willow is good for rooting cuttings because it contains high concentrations of Indolebutyric acid (IBA), and also salicylic acid, from which aspirin is derived and which protects against fungi and other pathogens. To make willow water, simply gather around 2 cups of fresh willow growth chopped up into short lengths.
Epsom salt promotes deep root growth for plants so during times of drought or little rainfall, Epsom salt plants will have deep roots to seek out moisture and nutrients. Plants with deep roots thrive when other plants with shallow roots shrivel up and die if water is not constantly provide to them.
The two main nutrients that support excellent root growth in plants are phosphorous and potassium. These two ingredients are extremely helpful in any fertiliser mix that needs to encourage a thick, healthy collection of brand-new roots, or to strengthen and stimulate existing systems.
Apple cider vinegar for rooting works as reported by many gardeners, although there is little evidence from horticultural research. Some of the natural compounds in apple cider vinegar may mimic rooting hormones. As a scarification aid, apple cider vinegar definitely works.
In many cases, sugar application increased the number of new roots formed by week 6 but had no significant effects on the length of existing roots or shoot growth. By week 24, increases in both root and shoot growth were recorded.
A root stimulator sounds like a fertilizer, but it's not quite the same. It contains a hormone called auxin that young plants produce when forming their root systems. Root stimulators typically have a host of other vitamins and nutrients that encourage the growth of roots, too.
Additionally, it breaks down into water and oxygen, providing oxygenation to the rooting medium, which is crucial for root growth. Therefore, these benefits contribute to improved success rates and faster root development when using hydrogen peroxide for propagating your plant cuttings.
Cinnamon as a rooting agent is as useful as willow water or hormone rooting powder. A single application to the stem when you plant the cutting will stimulate root growth in almost every plant variety. Give your cuttings a quick start with the help of cinnamon powder.
Cinnamon powder, a common household spice, doubles as an effective substitute for root hormone. Unveiling the hidden potential of cinnamon not only saves you a trip to the store but also leans on a more natural approach for your gardening projects.
Among its many benefits, which I appreciate more the older I get, aspirin is an effective rooting hormone. Dissolve one regular strength aspirin–not one of the fancy new pain killers–in a gallon of warm water. As you trim back the plants, stick the pieces in the aspirin water and let them soak for a few hours.
Success factors for rooting your cuttings
They'll root faster with plenty of sunlight, but avoid setting them in direct sun. Temperature is also important, the warmer the better to speed things up. For cuttings that are more valuable or difficult, adding a little aquarium pump to oxygenate the water will help a lot.
A Plant Hormone that Speeds Root Growth Could Be a New Agricultural Tool. Scientists have identified a plant hormone, beta-cyclocitral, that makes tomato and rice plant roots grow faster and branch more. The hormone could help farmers enhance crop plant growth.
Auxin (indole-3-acetic acid, IAA), produced in young shoot organs, promotes root development and induces vascular differentiation.
Prevent Fungal Disease
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
Among other things, phosphorus supports root growth and fruiting, while potassium supports disease resistance and plant hardiness. Phosphorus and potassium are not mobile in the soil and need close contact with plant roots in order to be taken up.
Can I Just Sprinkle Epsom Salt on Plants? Never apply Epsom salt straight from the package. Always dilute the granules in water first, and either drench your plants' roots or spray it on the foliage. Don't spray on hot or sunny days, however, to avoid scorching the foliage.
This is one of the most regularly used root stimulants. First, add 25 g of cinnamon (three spoonfuls) to a litre of water and leave for an hour. Then filter it and keep it in the fridge. Once ready, soak the stems for a few minutes.
Liquid and gel forms of root stimulators tend to be the most effective, safest, and easiest to use. BAC's Root Stimulator is one of the best root stimulator for plants. It is a high concentration solution that can be given at every watering and is available in various size bottles.
In this case, trace elements contained in apple cider vinegar promote plant growth, making it beneficial to cuttings. Simply mix three tablespoons into a gallon of water for a quick liquid rooting hormone.
