How to prune houseplants 
Use sharp scissors or garden shears. 
Make sure the scissors or garden shears are very sharp, as dull shears can damage the plants. If you notice any dirt on the shears, soak them in water with a teaspoon of bleach and then wipe them dry.
A clean tool will ensure your plants are not exposed to bacteria or pests when you prune them. You can find garden shears for pruning online or at your local hardware store.
