By Kathy Schwartz, Murray County Master Gardener Blossom end rot on tomatoes is caused by a calcium deficiency. Calcium moves through a plant when water transpires from the leaves. Usually there is enough calcium in the soil, but the main reasons for not getting to the fruit are irregular watering, poor air flow or excessive root rot. Water regularly and prune the lower leaves.
Surface roots of trees that grow slightly above the soil and dull your mower blades as you cut the grass, should be left undisturbed. Do not get out the axe. These roots are important to the support and well-being of your tree.
