Practical Tips for Gardening in Full Sun

Gardening in full sun requires some special considerations to ensure your plants thrive.

Watering

Plants in full sun need regular watering, especially during hot summer months. However, it’s important not to overwater, as this can lead to root rot and other issues.

- Water plants in the early morning or evening to avoid evaporation.
- Use mulch to retain moisture in the soil.
- Check the soil moisture by inserting your finger into the soil up to the knuckle.

Soil Preparation

The right soil can make a big difference in how well your plants grow.

- Use well-draining soil to prevent waterlogged soil.
- Add organic matter like compost to improve soil fertility and structure.
- Avoid using heavy clay soils that can retain too much water.

Low Maintenance Tips

For busy gardeners, low maintenance is key.

- Choose plants that are naturally drought tolerant or resistant.
- Use self-watering planters or smart watering systems.
- Mulch around plants to reduce the need for frequent watering.
