Things to do with gardening and landscaping.
Bonsai is a way of pruning and restricting the growth of a plant so it stays very, very small. The shape the plant grows is also changed, often making the plant look like a tiny, old, twisted tree.
Bonsai is achieved with a combination of careful pruning of both the roots and the branches, and using wire to shape the branches as they grow. Keeping the bonsai in a small container keeps the plant small, but great care must be taken so the plant doesn't dry out and die.
Compost is vegetable matter, rotted down so it can be used to fertilize and improve soil. You can make your own compost from lawn clippings, newspaper, food scraps and fallen leaves. Compost is best kept slightly moist, and turned regularly to aerate it. Worms in your compost will really help the composting process along, as the worms eat the food scraps and their castings become part of the compost.
Taking cuttings and striking them is a way of growing a new plant from a piece cut off from another plant.
The most successful way of taking cuttings varies widely depending on the type of plant. Some cuttings need to be of soft new growth, some hard, some taken in winter while the plant has no leaves, some in spring when it is vigorously growing, still other plants can be grown from only a piece of root or a leaf. Some need to be let dry a little first (hardened), some need special hormones, but as a general rule all cuttings need to be kept slightly moist so they do not die before they have their own root system.
The cuttings in the photo have been left to stand in water and have grown roots.
Dirt is a general name for the fine powdery stuff that is on the ground everywhere outdoors. Dirt is the name given to very ordinary sort. Rough dirt that doesn't hold water very well is usually called sand, very fine dirt that can also be used to make pottery is called clay and dirt that is good quality, either naturally or because someone improved it with compost, is called soil.
