Thought it might be helpful for us to say how things are going and any varieties that you've found to be particularly successful/unsuccessful so far, we can update it later in the year. Mine are :
Sucesses
Tomatoes - Red Alert are brilliant though none ripe yet. Gardeners Pearl I'm not so impressed with, a lot of flower drop. Have had one ripe one so far which was good but not fantastic. Principe Borghese and Golden Queen just at flowering stage so a bit behind.
Peas & Mangetout - kelevdon wonder, great but need many more next year. Mangetout as been very easy and definitely to repeat.
Strawberries - Year 3 for some of these plants and not as good as last year, though have had a fair few off them (DH's strawberry icecream is delicious !)
Parsnips - looking very healthy and very pleased so far.
Peppers & Chilli - DH's department. He has a couple of pretty impressive pepper plants with lots of baby peppers on. Chilli plants not quite so healthy looking but he does now have 3 green chillis.
Melon - donated by a friend and grown under a cloche. Looks as if I do have one baby melon, hopfully more to come.
Sweetcorn - growing fairly slowly as not as much sun as should be but am hopeful.
Courgette - one large plant going great guns, smaller one just started flowering.
Rocket - done well but has bolted
Spinach - as above
Spring onions - slow but fine I think
Pumpkin - think I can see first baby pumpkin.
Raspberries - DH's again, looking good.
Failures
Beans - slugs have eaten most of my climbing french ones and the dwarf ones.
Aubergines - have very healthy looking plants which have just started flowering but flowers are just falling off.
Thai basil - went yellow and died.
Chives - can't get them to germinate to save my life.
Blackcurrants - first year of no flowers and fruit at all.
Not sure if success of failure
Cucumber - germinated one from seed (Cucumber Perfection), in plastic greenhouse with two bought from market. Unfortunately not sure which type the market ones are so not sure if should be taking male flowers off. Shame as have a lovely looking cucumber growing ! Other cucumber plant has tiny one on that doesn't seem to be doing much.
Beetroot - not quite sure about these, might be OK.
Carrots - most of the sown directly in the ground got munched.
Blueberries - their first year, are in pots looks like there will be some but not huge amount.
