Grow plugs and peat briquettes make it easy for you to get started with propagation as well as transplanting small plants once they’ve matured. The seeds germinate well in the porous material and produce a good root formation. They also retain moisture for longer and you don’t have to carry heavy bags of soil. They are particularly suitable for those who want to sprout seeds early in the spring, and have stable small plants to move out to the garden when the time comes.
Grow plugs are also great for rooting your cuttings. Make the hole in the plug a little deeper and then push the cutting down. It’s an easy way to get several specimens of your favourite plant.
