Problems may involve direct injury, abnormal growth, or both. There may or may not be a remedy. Some problems may affect all vegetables, others one crop, one variety, or sometimes one or two plants.
Common problems with causes
If the plants are growing well this is frequently due to adverse night temperatures below 60 degrees F and above 75 degrees F. Also heavy use of nitrogen fertilizer will cause blossom-drop especially when applied at or closely after flowering.
Caused by insufficient calcium when fruits are forming, rot is characterized by a large dry brown to black and often depressed leathery area at the blossom end of fruit. Calcium deficiency usually results from improper soil pH, excessive nitrogen fertilization, rapid plant growth, and drastic fluctuations in moisture caused by heavy rainfall or drought.
Often a result of using old, large or overly-hardened transplants. Young transplants (5-6 weeks from seeding to planting in the garden) with 5-7 true leaves normally produce the best yields and fruit size.
Cucumber mosaic virus, a common disease problem in Georgia. Select mosaic-resistant varieties. Sudden rise in temperature or depleted soil moisture can cause wilting too, but plants will recover.
Several causes, like soil temps too low or too high, poor seeding techniques (too deep — lack of firming), maggots feeding on the seeds, birds, lack of moisture, too much moisture, soil surface becomes crusty, etc.
Low pH, low fertility, cool weather, lack of sunlight, poor drainage, too little/ too much moisture, poor soil structure.
This is normal for these crops under warm temperatures and long days. Spring and fall planting and proper variety selections are remedies.
Wrong planting date, non-adapted variety, crowding of plants or lack of moisture, especially early in growing season.
Inadequate pollination. Planting sweet corn in blocks of several short rows rather than in long single rows may help.
Lack of covering over developing potatoes is a common cause. Hilling soil along row as a plant grows helps to keep tubers covered.
A natural occurrence when summer temperatures arrive. Peas perform best planted in spring or fall.
Often due to a shortage of soil moisture. Cool temperatures at time flowers are developing can be a cause. Poor pollination due to lack of bees or low number of male flowers is another possibility.
