5. Apply thе correct fertilizer
You need to take care when fertilizing plants since too much of any fertilizer can burn roots, reducing their ability to absorb water. This, in turn, makes the plants more susceptible to stress from drought, cold, and heat. Plants starved for nutrients are smaller and can be badly affected by leaf spots, while a stronger plant can fight off diseases. An overabundance of a particular nutrient is another way to put stress on a plant.
Getting a soil test through your local extension agency will provide you with accurate information on nutrient levels in your soil. Without it, any feeding of your plants is likely to be guesswork on your part and may result in too much of one nutrient or not enough of another.
