Getting watering right first time
Wet flowers and foliage risk scorching and fungal disease
1 Make sure water goes straight to the roots of the plants. A good soaking twice a week is much better than a light watering every day, as this can cause roots to move to the surface, destabilising the plant, rather than questing down for water and nutrients.
2 Avoid watering flowers and foliage. Moisture that stays on the plant can attract fungal disease and moulds, and sunlight reflecting through the liquid can cause plant material to scorch.
