Yes, it is possible to add too little mulch. Anything less than 1 inch will likely result in too little coverage around your plants, allowing weeds to grow through and minimizing the positive effects that a deeper bed of mulch would have, like maintaining proper soil moisture and insulating the ground.

It’s usually best to buy plants from a local greenhouse or nursery yourself, but landscapers are also a reliable option. First, you can choose exactly what plants you want based on their appearance rather than relying on your landscaper to choose. Additionally, while it’s more time-consuming to go buy the plants yourself, you’ll often save money because landscapers charge for delivery and may upcharge the plants. You can also speak to a professional at a nursery to ensure you understand how to care for your plants and get the most long-term value.

The most important thing to put under a rock garden is the appropriate soil. The specific soil needed will depend on the type of plants you’re growing as well as the environment you live in. You can also put non-woven or woven fabric under the rocks to add to the garden's structural stability.

Yes, you can landscape in the rain, but you should take some precautions to keep yourself and your tools safe. Avoid using electric landscaping tools during rainfall, and don’t mow, thatch, aerate, or rake in the rain, as your tools can more easily tear out roots in the loose soil. Be careful when working on wet grass, and take your time to avoid slipping. Avoid putting in new plants before a particularly bad storm, as heavy rain and strong winds can damage or uproot plants that aren’t yet established.
