Prevent tomato and pepper blossom drop by ensuring plants are not stressed.
Tomatoes and peppers drop their blossoms when environmentally stressed. But when conditions are less extreme, a plant that has dropped its blossoms will flower again, set fruit, and be productive.
Temperatures too cold or too hot; weather too dry or too wet; soil too nutrient rich or deficient; these are reasons tomatoes and peppers drop their blossoms.
Best tips on How to Grow Tomatoes.
Here are reasons for tomato and pepper blossom drop and what can be done:
Causes of Tomato and Pepper Blossom Drop:
• Night temperatures below 60°F. Cover plants with floating row covers or plastic tunnels until temperatures warm. Wait to set out plants until night temperatures are warmer.
• Daytime temperatures above 85°F. Put shade cloth structures over plants to protect them from direct rising temperatures. Irrigate planting beds with cool water. In hot summer regions, time planting so that plants flower and set fruit before average daytime temperatures are too warm.
• A sudden shift from hot spell to cool temperatures. If cool temperatures are forecast, protect plants with floating row covers or plastic tunnels.
• Low soil moisture as a result of drought or lack of irrigation. Keep the soil evenly moist; avoid letting the soil go dry, and avoid overwatering to compensate for not watering. Work moisture retentive aged compost into planting beds.
• Too much soil moisture as a result of rain. If summer rain is frequent, plant in well-draining raised beds or grow plants on mounds. Spread plastic around plants so that excess water runs off into furrows.
• Hot, dry wind. Plant or erect wind breaks to keep winds from reaching the crop. Plant a dense hedge upwind of the garden or erect a windbreak or fence.
• Too much nitrogen in the soil. Excess nitrogen can cause rapid, succulent growth and disrupt a plant’s metabolism. Avoid high nitrogen soil additives such as bloodmeal and fresh manures. Use low nitrogen fertilizers such a weak compost tea or side-dress plants with aged compost, a balanced soil amendment.
• Too little nitrogen, potassium, or phosphorus in the soil. Give plants an even fertilizer—not too much nitrogen, phosphorus or potassium. Work aged compost into planting beds twice a year; the nutrients in aged compost are evenly balanced.
• Tarnished plant bug. The tarnished plant bug feeds on vegetable flower stems. The tarnished plant bug is ¼ -inch long, oval, flat and brownish. Control this bug by spraying with pyrethrum or dusting with savadilla.
• Verticillium and fusarium wilt. Fungal diseases leave plants stressed and fighting to survive; blossoms drop as the plant fights to overcome disease. Prevention is better than cure when it comes to disease: make sure soil is well drained; avoid overhead irrigation; space plants allowing for air circulation; eradicate weeds; remove and destroy infected plants; don’t plant members of the tomato and pepper family in the same spot two years in a row once disease hits.
Let plants set blossoms again. Tomato and peppers that suffer from environmental stress and drop their blossoms but do not succumb will commonly blossom again and set fruit once conditions improve. If plants experience early season or unexpected stress, give them optimal growing conditions as best you can and allow them to grow on. Many short-season or early-season tomatoes and tomatoes bred for hot summers are predisposed to resist early season stress and blossom drop. Tomatoes that resist blossom drop include Big Early, Floramerica, Hot-set, New Yorker, Porter, Red Cherry, Tiny Tim, and Walter.

My tomato plants are not blooming my daytime Temps R 99 – 105 can I move my plants inside to get them to bloom
If your plants are in containers, you can move them. If not, leave them in the garden and simply wait for the weather to moderate. If you have summers where temperatures are commonly in the 90sF or greater, you can delay planting so that your plants come to bloom later — perhaps in autumn — when temperatures are in the 70s and 80s.
my capsicum plant flowers fall every time. why and what can i do for it please help me
There are several possible reasons pepper flowers drop: (1) temperatures too chilly; peppers are best started in warm weather 70F or warmer is ideal; (2) too little or too much soil moisture; keep the soil just moist; (3) too much nitrogen in the soil; don’t add fertilizer until plants are 6 inches tall or taller; (4) failed pollination; the pepper flower is self-pollinating; when the pepper flowers give plant a very gentle shake; this will help pollen drop. You need to be a bit of a detective to find the reason but you can.
If I am growing my pepper plants in pots and I my plants are dropping their flowers, can I replant them with better soil? Will they come back and still produce fruit.
Pepper flower drop can be caused by insufficient pollination, very hot or cold temperatures, too much or too little water, too much nitrogen in the soil. You can transplant the plants to another container. Plants may suffer some transplant shock but will likely bounce back.
My tomato blossoms often drop. Temperatures in my region can get to 110 in the day and as low as 55 at night. Do you think the temperature swings are to blame?
The temperature swings you describe would certainly result in blossom drop, especially the very hot temperatures. If these are usual temperature swings for your region, you should consider growing in a more temperature moderate time of the year. Temperatures in the low 80s would be more hospitable for tomatoes.
