KIDS TRIVIA

Detailed explanation-1: -We found that 2 g.L−1 (2, 000 ppm) indole-3-butyric acid (IBA) in a 50% ethanol solution is the best concentration for rooting cuttings of a range of sizes, and that rooting declines with increasing basal diameter of stems, but increases with increasing length of stem.

Detailed explanation-2: -Rooting hormones increase the chance of your cuttings taking root. What’s more, the root will usually develop quickly and be stronger than when plant-rooting hormones aren’t used. While many plants root freely on their own (see below), using a root hormone makes the task of propagating ‘difficult’ plants much easier.
