Fall Planting

[BattleOfBennington]

Greetings -

I have always only done one planting in the spring of the year.

I am reading alot about fall planting dates.

Does this mean I should be culling beans, cukes, etc as we get close to mid summer, removing those old plants and putting new onesin the ground?

I am confused by spring and fall planting.

Anyone able to help decode this for me?

Thanks
