My butter beans plants are producing lots of beans that are growing and then curling up at the ends. What could be causing this and can i treat it with a fertilizer or a spray? I also have Zucchini that the flower covers all of the end rather then the tip they grow about 3-4 inches and then go yellow and shrivel up?

Research on the internet, what causes curly beans. Go the Gardening know how webpage and read. I think the zucchinis are a bit of a mutated seed or whatever. I had a plant like that, big fat end zucchinis with a big flower. Sounds like the female flowers are not being pollinated. Try it by hand.

Check the plant day and night for grubs.

Look under the leaves etc and see if you can find grubs etc.

My tomato bushes are great and promise a bumper crop again this year. As my mother before me, I dig cow manure (from the shop) into the bed six weeks before planting the seedlings. My mother added liquid manure to hers as well.

A general all round fertiliser grows most things.

I found the same thing happening a few months ago with our tomatoes (Black Russian and Moneymaker). I found out it is Cotton bollworm: a nocturnal moth which lays it's eggs on the flowers, which then hatch and enter the baby tomatoes when they are tiny. I have my tomatoes string-trained on a 'cage' structure made from sticks/branches, so I used a Vege Net from Green Harvest over the entire structure, pegging and tucking the edges in (placing plastic flower pots over the tops of the sticks/branches, to prevent holes in the net). There was a period of finding spots developing, and caterpillars inside the tomatoes for a few weeks after, however no fresh infestations. I'll be doing the same this year right from the start.

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
