Most important gardening numbers revealed

Gardening may seem like an inexact science to many, but these days nothing could be further from the truth, according to one writer.

In an article for Florida ‘s Herald Tribune, Linda Brandt has revealed some of the most important numbers for greenhouse and gardening enthusiasts to bear in mind.

First of all, it is vital to get the right soil pH, as it determines how nutrients are absorbed by plants.

“The pH scale ranges from 0.0 to 14.0,” she explained. “The lower the number, the more acid the soil; the higher the number, the more alkaline the soil. Although the range for plant growth is between 4.0 and 9.0, most plants prefer a pH between 6.2 and 7.0.”

Secondly, sun exposure is crucial to plants’ successful development, Ms Brandt remarked, depending on their requirements.

Full sun is regarded as at least six hours of sunlight per day, partial sun means three to six and full shade means less than three.

Check the label when buying a plant to see which one to use, the expert said.

Finally, gardeners must make sure they use the right amount of mulch, with one cubic yard of mulch perfect for covering 108 square feet at a depth of three inches.
