What Is Ecology?

The term comes from the Greek 'study of house', or the study of the place we live in.

Growing strawberries in the garden

Growing strawberries in the garden 1 Plant at the right time.   This will be determined by the strawberry variety you've chosen, so read the label or consult the retailer from whom you're purchasing the plants. [1] Large fruiting varieties of strawberries are best planted in summer, usually in the second month of summer and at the latest, by the first half of the last month of summer. Alpine strawberries are best planted during the second and third months of spring.

(This planting time is appropriate for gardens in temperate climate zones.) 2  Choose a warm and sunny spot.  Strawberries love areas that get a lot of direct sunlight without shade. They also appreciate minimal wind. A strawberry plant will produce strawberries in partial shade if need ...
