Things to do with gardening and landscaping.
Mulches can be made from many things, but the most common kinds of mulch are decorative gravels, pebbles, bark, wood chips and leaves. Mulches made from bark or leaves will slowly break down and make the soil better.
"Plant" is a word that covers an enormous number of living things in the world. Plants can be divided up into several groups, namely algae (that green slime you find in ponds), bryophytes (non vascular plants, or mosses and lichens - the small, often fuzzy plants that you see growing on rocks or on the ground in damp corners) and tracheophytes.
Tracheophytes, or vascular plants, are the most familiar. They include all the trees, ferns, grass and flowers you see around your neighbourhood. The plant in the picture is a vascular plant, growing in a pot.
Stakes usually have one end sharpened to a point, which makes it easier to drive them into the ground.
