Well I am a newbie to this site too although I am not a COMPLETE newbie to veg growing. We had an allotment where we lived before - there was no access to water, the weeds grew faster than the veg did and what we got was decimated by rabbits! It was a thankless task - so why did we think we could do it? Well my husband was made redundant and out of work for three years, and I was the main breadwinner. He did all the digging and preparing of soil. I did the weeding (which was relentless). He planted all the heavy backbreaking stuff like potatoes, did all the fencing and supporting, and I planted stuff out, sowed seeds etc. It was very hit and miss but we were struggling for money and were trying to be a bit more self sufficient. I was doing my bit after a long week at a full time job and I was also teaching 3 evenings a week on top. However, the amount of time we had to spend on the allotment just to gain a few carrots or leeks (after having to replant stuff because of the rabbits) was not worth it and I can understand why other gardeners feel that they want to get the rotivator in or a "man with a spade". Part way through the allotment saga I became seriously ill with pneumonia (in the summer!) and the whole project went to pot. All those months just wasted - and then the rains came, and continued. We were constantly battling the elements (windy site in N Yorks) and to be honest, we were probably trying to rush the planting to beat the weather and because we were desperate to get some food out of the ground.
People grow veg for many different reasons - some because they like to, for others it is a hobby (the way knitting and craft, or cooking are also hobbies for me), some may be doing it just to get out of the house and get some fresh air (or away from the OH!) and for some it is a necessary way of life.
I really don't think we should be knocking anyone who wants to have a go at growing things - it is their decision as to how they go about it and they have to base that decision on their own lifestyle. I am now in a house with a larger than average garden and it is so much easier to tend part of my garden as a veg plot than deal with an allotment. I am on site all the time, I don't have to use petrol to ferry pots of seeds and water to the allotment (anyone taken that cost into account?) and we are not over-run with rabbits because we have a wall around the garden.
I also still have health difficulties which affect my knees and my back and if my husband wasn't here to be able to do the odd bit of digging for me, I too would have to find "a man with a spade" to turn over the soil.
I don't often feel the need to have a rant, but I did today - I appreciate the advice all you experienced gardeners have given me, but please remember that there is more than one way of growing veg and everyone has to make their own choices about what they do - and live with the consequences.
Sorry to be on my high horse, especially as I am new to the forum, but I thought the other side of the argument was worth bringing to the fore.
