When is the best time to apply foliar fertilizer to autumn tomatoes? Please give guidance and explain the reasons. Autumn tomatoes are affected by high temperatures, strong sunlight and dry weather, so flower drop, fruit drop and fruit cracking are relatively serious, and misshapen fruits and blossom-end rot fruits are also prone to appear in large numbers, with a low fruit-setting rate. If at this time a 25-30 times dilution of superphosphate mixed with dry, clean plant ash leachate, or a mixture of 300 times calcium nitrate, 500 times monopotassium phosphate, 800 times humic acid active liquid fertilizer, and 1500 times Shengnongsu chelated fertilizer, can be sprayed on the foliage once every 7-10 days...
