How to Control Disease on Your Flower Annuals
It is also important to look for signs of disease or insect infestation every time you work in the garden. For instance, as you are pulling weeds, look at the plants. Are the stems intact, or are they showing signs of cracks or other damage? Is the foliage leafy, green and free of holes and spots? Catching problems early is the best way to cure them.
When watering annuals, it is best to avoid overhead watering if you can. That is because splashing a lot of water on the foliage of plants can encourage a variety of diseases. Most plant diseases love moisture, and standing water on plants is a great way for existing diseases to spread throughout the garden, or for a new infection to take hold.
A combination of drip irrigation and soaker hoses is usually the best choice for watering the garden. These methods allow for greater control over the amount of water each plant receives, and they generally allow for deeper, more thorough, watering as well.
