Some of the most spectacular gardening is on the rooftops and patios of the world's largest cities. Today's homeowners and apartment dwellers do not have to discard gardening. In fact, they can create their own garden hideaway.

Gardening in small space means you plant in containers, choose plants carefully, grow up on trellises instead of outdoor, hang plants from something overhead. Herbs, vegetables, shrubs, and citrus fruits can all be grown in containers. More and more vegetable varieties are available specifically for container growing.

For small-space growing people can grow in everything from custom-made pottery to clay pots and wooden planters. Your gardening containers must have drainage holes at the bottom. Cover the holes with a section of window screen so the soil doesn't leak out.

Get a bag of dry, soulless mix for container gardening. You need to soak the soil with water before planting. This process can be messy, so plan ahead and do it outside if possible. Moisten only as much as you'll need for the current task.

Keep an eye on your gardening container. It can dry out quickly in hot weather. If you really get into it, you might want to consider a drip irrigation system. This is a network of plastic tubing that can be regulated to provide a constant moisture supply to your plants.

Most plants need an average of 1 inch of water every week. You should try to water your garden plants earlier in the day, so the sun can help dry off any water left on the plant. If you see a plant drooping, be sure to water it, because some plants wilt and do not recover if they dry out.
