French dwarf beans

I planted them on 11/4/2017 and  beatroot  but there is no show  I know it's been cold  do you think I've lost them or will I have to plant them again  My allotment is in Harlow any help most appreciated

I've not got a green House so When is the best time to put the French dwarf beens direct in to the ground

I am in North Lincolnshire and would not put direct in ground until about third week in May. Would look at weather forecast for weather warming and whilst no guarantees a period with no cold and wet to come. Worth a try with a few seeds earlier under fleece or cloches to get at least a meal or two before those sown at a safer date start to yield. Personally I start mine in greenhouse about now and then protect until frosts less likely towards end of May before planting out. A few plants in polytunnel about now will give an early crop and for succession sow a few seeds every couple of weeks right through to end of July is worth the effort. Can still be taking a crop as late as October with a little protection. We all get tempted to sow to early and this year was very tempting but later seeds often catch up and do better than the earlier ones.

i put a row in 3 weeks ago an there up with 2 leaf showing
