What a soul destroying season

I have to say (and I have had some bad years) that this has turned out to be such a terrible season for me because of a lot of strange problems that can't be identified.

Broad Beans: Started out healthy and flowers fell off leaving the odd distorted, small beans. Small holes in leaves (see other post with pics) which progressed later on to worse.

Broccoli: All skeletal now because something has eaten them. Covered with netting but hasn't helped.

Salad leaves: Thin, twisted and distorted with mottled markings on them later on in season. Basil started lush in the greenhouse only to be eaten by something (not slugs). In fact all other greens like spinach, rocket,coriander,mustard greens were pathetic despite planting in fresh compost and the soil.

Courgettes: Only putting up male flowers and so far no change. Yellowing leaves.

Amsterdam carrots: Sown very early in season in container with fine compost and sand. Again, tiny pathetic things with holes in them. Kept in greenhouse most of season so how did the fly get to them ?

Radish: Terrible. Hard to grow any with a decent bulb and most bolted despite keeping in cool shaded area of garden.

Beetroot:Pathetic, bolthardy bolted. Other variety's didn't grow.

Onion sets (red and white) some in container did ok, the rest in ground and other containers stayed the same size and some shoots withered away early on. Cheap Home and Bargain store 99p sets so perhaps this was the cause ?

Poached egg plant: 2nd year when they have not grown any bigger and then in fact get smaller and smaller. Of about 20 plants I have about 1 or 2 that are just about alive.

Chard: The one that got going ended up bolting. Can never grow these successfully.

Spuds: In bags no spuds. In the ground decent crop of Charlotte.

Peas: had a few attempts at sewing but kept rotting in pots. Eventually got some plants going but quite late on. Small crop not too bad but other years been much better.

I could go on but you get the idea. I am doing everything I can correctly but mainly the pests have destroyed everything. I have had saw fly, aphids, slugs, flea beetle, thrips, leaf miner, carrot fly, caterpillars galore, and whatever has made a lot of my leaves paper thin like tissue. I have a pond with frogs and I am trying to keep the garden organic and wildlife friendly. I attract hover flies, birds and it's a small walled garden.

Please don't think this is a moan or rant. It isn't, it's a genuine cry for help because I want to do as much as I can before next season to eradicate whatever I can eradicate so it doesn't happen again. This is by far the worst for pests and I haven't seen a single red ladybird this year at all. Butterflies have been cabbage white most of the time.
