I learned if you want a steady supply to
plant a second and third crop of cukes, at four week intervals after the initial planting.
Also I like to spray sparingly every 7-10 days untill they have cucumber blossoms. This keeps the beetles away and gives the
plants a strong start.
I have grown lots of varieties, but Bush Pickle resisits cucumber diseases the longest. Don't let the name scare ya, the variety produces a nice never bitter cucumber and is very prolific.
I am trying Gurneys Hybrid 2 this year also. It also is suppose to resist disease and not be liked by the cucumber beetle. I planted two in mid June
and have yet to find a cucumber beetle on them.
