To start a successful garden, choose the right location with plenty of sunlight and good soil drainage. Test your soil's pH to ensure it’s suitable for the plants you want to grow. Adding organic matter, like compost, can improve soil quality and provide essential nutrients. Regular watering is crucial, especially during dry spells. Aim to water early in the morning or late in the afternoon to reduce evaporation. Additionally, consider using mulch to retain moisture and suppress weeds. Remember to rotate your crops each season to prevent soil depletion and reduce pest problems.
