I have found gardening to become a passion over the years. Veggie gardening is rather new to me as my hubby usually does that, but it certainly can be rewarding to the budget, the health of anyone eating organically grown veggies and the health of the planet. Just think of the fuel saved by having your dinner right in your back yard or on your patio.
One thing I've found by having a veggie garden is the need to 'do something' with all the extras that many folks have. Some folks share with family, friends and neighbors and some donate to local food banks. One of my daughters actually learned how to 'can' her leftovers. This all came at a time when she was a new single mother of 3 and was having financial difficulties. She constantly called me for guidance and help. She was fortunate enough to be living on a large piece of property so she was able to plant many fruits as well. Sadly for me, she never quite got the 'organic' passion I have, but at least she saved alot of money and developed new skills for herself and her 3 young daughters.
Btw, my father was an electrician and I would often go to work with him on weekends for his side jobs when I was a little girl. He taught me alot and I'm always grateful for that. Hopefully work will pick up for you soon.
When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
