Each and every vegetable crop grows best possible in its private range of temperatures. The optimal temperature range for peppers and eggplants, for example, is 70° to 85°F; pollination may not occur if the night temperature falls below 55°F, and blossoms would perhaps fall if the temperature rises above 85°F.
Bean blossoms would perhaps drop off if temperatures keep warmer than 85°F for more than a day or two. Tomato plant lifestyles would perhaps drop if the temperature rises above 90°F right through the day or 75°F at night.
When temperatures upward thrust above a plant’s temperature range the plant will move dormant–that is give up expanding (the an identical is right kind when temperatures fall below the variability). If temperatures move too best, plant’s can go through sunburn and sunscald and plant cells can experience chemical alterations, membrane hurt, dehydration, and loss of life. Most plant cells are killed at temperatures from 122°F to 140°F.
Just right sufficient water and colour can lend a hand scale back blossom drop and cellular hurt when temperatures are extremely popular or sizzling. Feeding and fertilizing will have to be decreased or stopped right through extremely popular and sizzling local weather.
Expect loss of blossoms or plants when temperatures deviate from a crop’s temperature range.
Optimal vegetable-growing temperature ranges, with the highest end of the variability given first:
• 95°F to 65°F (optimal 85°F to 70°F): eggplant, sizzling peppers, okra, sweet potato, watermelon.
• 95°F to 50°F (optimal 75°F to 60°F): corn, cowpea, New Zealand spinach.
• 90°F to 60°F (optimal 75°F to 65°F): cucumber, muskmelon.
• 90°F to 50°F (optimal 75°F to 65°F): chayote, pumpkin, squash.
• 85°F to 65°F (optimal 75°F to 70°F): sweet pepper, tomato.
• 85°F to 45°F (optimal 75°F to 55°F): chicory, chives, garlic, leek, onion, salsify, shallot.
• 80°F to 50°F (optimal 70°F to 60°F): bean, lima bean.
• 75°F to 45°F (optimal 65°F to 60°F): artichoke, carrot, cauliflower, celeriac, celery, Chinese language language cabbage, endive, Florence fennel, lettuce, mustard, parsley, pea, potato.
