What will you never grow again?

Broccoli ( I don’t do any other brassicas). Beautiful plants with fab heads, full of black beetle!

Arum italicum pictum. (The one with variegated leaves.) It is desperately invasive and leaves tiny dark bulbils deep in the soil which are impossible to completely remove. I eventually resorted to black plastic and bark mulch across a whole flower bed.
And brassicas!

Agree, brassicas are too problematic. Im trying to convince my husband we should stop growing courgettes. I don’t really like them, and even one plant produces too many for just him (in my view, not his. Yet).

Any brassica. They attract every cabbage white in the country and are devoured by the caterpillars in no time at all. If you manage to evade that hazard, the result is so pathetic… any, E Kent is the brassica capital of the country and we can get them very cheaply…

Carrots never seem to grow for me - even the miniature varieties.
Stinking Iris a friend ? gave me for my new garden years ago - but it spreads too much & a devil to pull up once established. ( glad I've moved house). Same with pampas grass.

Tomatoes.
Months of loving care, having to have neighbours tend them when away from home, the expense of the best compost and fertiliser then when they are finally ready for picking tomatoes are as cheap as chips in the shops.
OK they do taste so much nicer (especially Gardener’s Delight) but the commitment became too much.

Cucumbers and tomatoes I don’t have success unlike my dad every year his were brilliant.

Melons. I tried growing them for three or four years in a row (using the same packet of seed). In all that time I only got two edible ones, and they were really small!

Onions and garlic, but that's because there is white rot in the soil. My leeks can survive it, but not the onions and garlic.

I used to think that karmalady until I discovered debris netting, much cheaper than environmesh. The slugs, we use pellets, the ones without metaldehyde, so animal safe.

also marketmore cucumbers. 4 mini cucs from two plants and I fed and watered them

Cucamelons! Waste of water, greenhouse space and time. Also most brassicas due to everything that lurks in them despite careful netting.
