You can garden anywhere in pots and containers. A container garden on a balcony, patio or deck can produce a lot of flowers and vegetables, and it often makes caring for your garden even simpler. If you start from seed, you can use the seed packet stapled to a stake with the child's name written on it. Bedding plants usually come with a plant tag you can use. Colorful pictures help children imagine what will grow.
Children love to water - particularly at full force of the hose.
You will want to remind them that rain usually falls a little more gently and that they should imitate the rain. A personalized sprinkling can is a good idea for younger children. Weeding is another matter. At first, even for adults, it can be difficult to tell small wanted plants from small unwanted weeds. You may want to let things grow a little before weeding too much.
