Every gardener knows that keeping pests and diseases out of the garden is a full time job. The term "disease" includes attacks by fungi, virus infection and bacteria. In most cases, the presence of diseases especially, is an indication that the plants' resistance has weakened. Usually plants in top condition are quite resistant to diseases - there has been tests conducted where mildew from an infected begonia plant, when transferred to a thriving one, does no harm to it at all.
There could be many reasons why a plant fails to thrive. To find out, check its natural habitat to make sure that the plant is receiving a condition that is as close to its natural environment. Some plants are very sensitive to the change in condition, and will fail to thrive if the right condition is not met. Naturally at times it is impossible to recreate the climatic condition of the plant in its natural habitat. Nevertheless, a gardener should always pay attention to the amount of light, temperature, moisture and atmospheric humidity, and select plants that he can grow within the limitations of his garden.
The following is a list of pests and diseases that are likely to affect your garden plants and trees.
Aphid
Cockroach
Leafhopper
