Why your cucumber plants' yellowing ovaries aren't a fertiliser problem

Alexander Sidelnikov, a gardener and member of the Russian Botanical Society, has shared insights on common cucumber-growing mistakes. He spoke with 360.ru about why gardeners often misjudge the cause of yellowing ovaries in their plants. Many gardeners assume yellowing ovaries mean their cucumber plants need fertiliser. In reality, the issue usually stems from incorrect temperature or humidity levels, not a lack of nutrients. Adding fertiliser in these cases does more harm than good.

Sidelnikov explained that mineral nitrogen fertilisers can lead to rapid nitrate buildup in the fruit. These should only be applied two to three weeks before harvest. For dropping ovaries, growth stimulants like Epin, Zircon, or Gibbersib are more appropriate. The advice highlights a frequent error in cucumber care. Using the wrong treatments can damage plants and affect fruit quality. Gardeners are urged to check environmental conditions before reaching for fertiliser.
