1. What is the purpose of putting something at the bottom of large garden pots?
Putting something at the bottom of large garden pots serves multiple purposes. One of the primary reasons is to improve drainage. When water accumulates at the bottom of a pot, it can lead to root rot and other water-related issues for your plants. By adding materials that promote drainage, you can prevent excess moisture from sitting around the roots, allowing for better aeration and promoting healthier growth.
Additionally, adding a layer at the bottom can help in weight distribution. This is particularly important for larger pots, which can become quite heavy when filled with soil. By strategically placing lighter materials at the bottom, you can make it easier to move the pots around your garden while still ensuring that your plants receive the proper support.
2. Can I use gravel or stones for drainage in large garden pots?
Yes, gravel or stones are commonly used for drainage in large garden pots. These materials allow excess water to flow through easily while preventing the potting soil from washing out through the drainage holes. A layer of gravel or small stones can create a solid foundation that supports the base of your plants while effectively directing water away from the root zone.
However, it is important to note that while gravel and stones facilitate drainage, they may not always retain moisture well.
