What to Look For Before You Buy?
If you are new to this, you might not be aware of what some of the must-have criteria are in a good quality rooting hormone. Even many professionals get confused at times and only know more through experience.
To guide you through this trouble, we have prepared a list of the features that you need to look for before you buy a root growth stimulator for your plants:
Type of Root Hormone
Root hormones generally come in three forms, which are liquid, gel, and powder. Each has its own perks and cons. You need to make sure which type will suit your preference before you choose your pick.
To help you with this, we will mention the features of each of the types. Although all the formulas provide similar benefits, the consistency adds some additional perk. For example, the best characteristic of the gel-based formula is its viscosity. It does not easily spill and therefore is safe to use around children and pets.
The second type is the liquid one, which is very easy to apply. It only needs to be diluted with water. This type of root hormone also is quite economical. Lastly, the powdered formula is the most common choice amongst gardeners.
This one clearly shows the coverage it is providing to the stem, which makes it easier for both amateur and professional gardeners to understand whether the product has been effectively applied or not.
Duration Taken to Work
Plants come with their natural rooting hormones that take a long time to work. Therefore, artificial hormones are used to fasten the process. Most effective products take about 3-5 weeks to complete work on the roots.
However, make sure always to prepare 2-3 cuttings from the same plant because the rooting hormone might fail on one or two of the cuttings if not applied properly.
Check if the root hormone you are buying can provide other benefits or not. This helps to realize the value of your money thoroughly and also fastens the plant growth process. For example, some root hormones can enable protection from diseases and fungal attacks.
You will also see that several picks on our lists prevent transplant shock, which is an important criterion to look for to prevent your plants from withering while moving.
