Containers,hanging baskets and raised beds are examples of items people use to create a garden in a confined space.Some cities also offer a shared community garden for people who have no room to grow plants at home. Many types of plants can be grown in containers and baskets.Tomatoes andpeppers,for instance,can grow in containers on windowsills(窗台).Plants grown on a windowsill should usually receive at least six to eight hours of sunlight daily.Herbs are often grown in containers or baskets in the kitchen.They do not require much space and can be handy for cooking. People who want to grow more plants may use raised beds which are usually made of wood pieces and flled with a mixture of soil and fertilizers.They can be built on top of any hard surface,including roof tops.People like them because the beds often cost much less than most other methods of gardening. Community gardening could be an option for anyone who does not have spacefor a garden at home.Most cities that offer this will rent a small plot of'land to someone for a fee,or allow them to use it free of charge.Instead of dividing the land into separate plots,some cities allow everyone inthe neighborhood to share andwork on the same land.This method could be beneficial for people in the neighborhood who share the passion for growing things.
