<human>:  How can I plant a garden in a small backyard?
<bot>: Firstly, consider what plants you would like to grow and buy the appropriate seeds or seedlings. Once you have done this, you will need to make sure your backyard is adequately prepared for the garden, which involves clearing any existing weeds, stones and other debris, as well as tilling the soil. After this is done, it is time to plant your seeds or seedlings. Generally speaking, seeds should be planted around 2-3cm deep and you should plan your rows to provide adequate spacing for the plants to grow. Once you have planted the seeds or seedlings, make sure you water them regularly and keep an eye out for any weeds or pests. With some patience and care, your small backyard garden should soon be in full bloom!
