These nutrients are available in the soil in very small quantities. Nutrient deficiencies are not common, except in the high pH soils, particularly the […]

Changing Garden Soil pH

In general, the garden soil pH fluctuates only slightly unless you accidentally spilled fertilizer or limestone. Soil pH is also affected by rainfall patterns, decomposing organic matter, and bacterial activity in the ground. In the eastern U.S. rain water is slightly acidic. Acid rain is the result of these pollutants (mostly sulfate and nitrate) from […]

Temperamental Big Leaf Hydrangeas

Get use to it… big leaf hydrangeas (Hydrangea macrophylla), also called hortensia hydrangeas, are temperamental (USDA hardiness zones 6-9).
