I know the feeling, I have the same problem with next doors chav cat. I have a couple of ultrasonic deterrents (Like these)that worked, but the cat went deaf (too much chav BnD). Have now got a water squirter (Like this), that has worked a treat ) Cats do not like water (or bags with bricks in... cough, or shot guns.... cough cough)
Anyhow my progress to date this year:-
Courgettes - Put out too early and hit by the frost, not dead but not looking too well
Tomatoes - Going very well. Need to clear the greenhouse of non-hardy annuals and get them properly going. Trying some trailing hanging basket types this year aswell.
Onions and garlic - Going very well (except the ones the girlfriend put in upside down)
Peppers - Also going well under glass, about ready to pot on.
Cucumbers - Plants doing well, but need to get into grow-bags
Beetroot - Outside after being set-off in greenhouse, doing well.
Carrots - Just braking through.
Spuds - need to earth up, but growing well (reduced number this year and limited to containers after poor harvests the last 2 years)
Strawberry (in pots)- Have done well for being over-wintered in the greenhouse. On second crop of alpines and main-crop are fruiting well. Will be a shame to kick them outside, but need to make room for the tomatoes.
Lettuce - Have started to recover from the great drought (forgot to water them for a few weeks). Fortunately they have not bolted. The plants in the garden seem to have missed the frost, so all good.
Runner Beans, Sweetcorn, fennel, spinach - Will grow better if I get the seeds out of the packet.
