It has been raining for over seven days.
Are they in ground ??dig drainage ditches for water to flow away from plants,protect tops from rain with tarps,shade cloth,if vines are on ground get them propped up off ground so they can get dry easier.Or in containers? move containers in & out of rain into sun when it comes out,make sure the comtainers have drainage holes not too big you loose soil but enuf for water to seep out.if flooded dump out excess water,transplant with dry new soil if really bad.here's some additional info.what to watch for disease from too much moisture http://archive.jsonline.com/blogs/lifestyle/51573447.html
Hi Sherry. Add soil around the base of the plants to protect root system from erosion. You can use a trellis for cucumbers but that usually goes in when plants are young. You could probably still put a trellis in and secure the plant to it. Use pipe cleaners to secure the plant to the trellis. Anything like string or wire will cut into the stalks. Another way to keep the cukes from rotting on the ground is to make "hammocks" for them. Use old nylons to make the hammocks and tie them to a trellis, or even a tomato cage. Getting them off the ground is key. Cucumbers are a water plant so I think they'll be OK with all the rain. Good luck Sherry.
They should be fine
