The healthier a plant, the less likely it will be affected by a disease. Providing sufficient water, light, sun, air, regular weeding and nutrients are essential to plant health. Maintain planting distances as specified on the seed packet. Planting too densely allows moisture to get trapped, and becomes a breeding ground for fungi and other diseases.
Select disease-resistant plants
Select plants and seeds that are resistant to common pests. These are not genetically modified plants, but rather natural varieties that have been bred for stronger resistance.
