I live in New Mexico where its been over 100 each day.

My cucumber plant was growing very healthy for a few weeks now. I do regularly watering. It grew about 8 full sized cucumbers already.

All of a sudden a few days ago the leaves started turning yellow and dying.

The plant had tons of baby cucumbers flowering which are now shriveling up and dying. There was also a weird white powder at the base of the cucumber.

  • Then maybe not too much watering. Could be rodents or insects eating the roots. You should show us one of these "white spots" also. But you can only post 2 pictures. I suggest you remove the second picture, and include a close-up of the cucumber inside that one, and post it again.

Your cucumber plant may not be dying. Slight yellowing and browning is normal during summer time. Help your plant by cutting off these yellow and brown leaves immediately.


Cucumbers need light intensity in the range of 10,000-20,000 lx and exceding this optimum causes premature senescence of the plants, meaning they age rapidly and then they die. Provide a little bit of shade for your plants if light intensity is too high.

Also, temperatures above 90°F (32°C) causes the plants to age earlier. My guess is that high temperature wouldn't age your plants so rapidly if the light intensity was in the specified range.
