V.H.
We have tried many things and here's what I've learned. Use the when to grow guides for best results and things will grow as long as you are attentive, but if you want your garden to thrive the two things you must do are get Mel's Mix, (you will find how to get that by checking out Square Foot Gardening) and set up a drip system. Most things die here if they have to depend on me remembering to water them. The difference in Mel's Mix is truly amazing and though your items from seed will grow, like our corn that is already taller than me, the watermelon and pumpkin plants do much better than the ones from seed.
The best thing we ever did was read Square Foot Gardening.
Do it w/ Mel's Mix and you will be much happier w/ the results. Remember to water and check for bugs (we spray)
Enjoy your garden!!!
