Timely tendings: vegetables, chrysanthemums and magnesium deficiency

Vegetable gardening continues, including okra, cantaloupes, okra, sweet potatoes and summer spinach.

In terms of flowers, if you're planting chrysanthemums (Chrysanthemum spp.), the small-flowered varieties, when 6 to 8 inches, should be pinched every two weeks until June 10. After that, let them bloom.

Most Florida soils are low in magnesium. The signs of magnesium deficiency occur on older leaves because the nutrient is able to move from old to new growth. Magnesium deficiency is common in many ornamental and food plants. It will make the older leaves of the Canary Island date palm prematurely yellow. In grapefruit trees, the leaves adjacent to the fruit may be the first to become chlorotic. The problem can be corrected with magnesium sulfate.
