The most important thing in a garden – plants! The first thing you need to do is study your garden. Before you pull out any plant, wait for a few months. You might see unexpected and delightful change in the plant over time. There might be plants that provide the most beautiful flowers, and you just didn’t know. So wait for some time, till spring if you can, to see what the plant has to offer. Some sickly plants that look like they are about to die, may bloom into beautiful luscious foliage if given the proper care. Make a note of all this for future reference.
When you plant a scrub or tree, do a little study about them. It always helps to know how they inhabiting your garden. Also know what seasons they are most robust at.
