This afternoon I put up a trellis for cucumbers and squash. It went up far more easily than I thought it would and looks pretty neat. (I am so thrilled with the SFG method - it's so comprehensive, simple and effective. God bless Mel Bartholemew.) I used green plastic covered metal stakes ( 2,79 Euro each) and green plastic netting for beans (4,75 Euro) also at the local DIY. The stakes went into the ground without any trouble. They are pointed at one end and at the other there are grooves to hold the netting in place.They're also ridged so that the netting can be attached to the pole with cable ties without slipping up and down.
I've planted a cucmber plant already - I hope it's not too early - but if there's any danger of frost I can cover the wire cage with plastic. The cucumber plant is not yet taller than the top of the cage. When it becomes too tall I'll cover it with a tomato plant sheet.
