Cabbage moth and other pests

So I started off thinking my cabbage just had aphids (thank you for the earlier help), however I then discovered cabbage moth.  I gave my mum 4 of the cabbages as i only have a very small space.  Keeping two I re-planted them in seperate containers.  I've sprayed all leaves with soapy water and sprayed with water.  I found two quite big cabbage moths.  One of the ground eating the leaves and another inside the centre.  I re-sprayed the centre with soap.  Is it going to be like this the entire growing season?  By keeping the cabbage am I putting the rest of my garden at risk from other insects?

I found black fly on my geraniums and butterfly larvea (yellow buds) on my curly kale.  I'm growing potatoes, tomatoes, runner beans, squash, strawberries (something is eating the leaves on this as well), spinach and a wide variety of herbs.  I love my garden and I am leaving it in my brothers inexperienced hands for two weeks as I go away. I've washed all the leaves with soapy water and water sprayed them all so far. 

Any advice would be gratefully received.  I attach photos of my little garden.

firstly, may I compliment you on your lovely garden! I especially love your hanging herb arrangement!

unfortunately anything brassica like need fine netting which would probably would ruin the look of your lovely garden but would stop the cabbage whites from infesting your crops.

I only grow brassicas on my allotment as they need a lot of space and even more to allow for the netting required, and only grow crops which don't, in my vegetable plot at home.

im sure someone more knowledgeable than me may be able to give some advice, but I am really impressed with what you have achieved in (what looks like) a small space....you should be very proud!

You could try growing perpetual spinach as a leafy veg.

That is one lovely garden! Strawbs are usually attacked by slugs and snails but it could also be woodlice as we get them in our raised stand.

Thank you so much everyone!  I got rid of my cabbages to my neighbour who has a larger garden too much effort.  I'm going to continue with the one pot of kale I have and will buy some mesh tomorrow. 

Could anyone please advise me if my squash is a goner!  It is a baby but I turned it over today and saw it had brown on it.  The leaves have been eaten but I laid it on the bench until I got some trellis so I put it down to this.
