I read an article in the Old Farmers Almanac about when to water your veggies. Here is a link to the full article. However here is a chart as well.
Also How to Measure Your Water
If you set up a rain gauge or bucket in the garden, you can measure how much rain or irrigation water your garden is getting and time how long it takes your watering system— or a good steady rain—to drop an inch of water. Use a clean, empty tuna or vegetable can as a gauge. Measure its contents by putting a ruler into the water it collects.
Container Gardening.. All kinds of things from how to make your ouw potting soil to hanging baskets, window gardens and raised beds. Containers with veggies, flowers and herbs. Herb solutions and more.
My yard has hundred year old Maples and others overhanging from the neighbors' yards. A tree's roots go as far as the branches reach.And so my yard is FILLED with a web network of very thirsty roots. I had trouble with my flowers and ground vegetables drying out in 1 day.When getting a professional assessment I was told that anything I plant in the ground will be robbed of the water by the trees. Nothing has a chance. My new raised garden beds now have tree roots growing up into them. Next year they are being dismantled and the raised beds will be waist high with a false bottom raised off the ground. They do sell them, but the problem is finding a model sturdy enough to last for a few years with the weight of snow in the winter.
My vegetables do very well now because I have a few Earthboxes. But the flowers in the ground have to be watered EVERY SINGLE DAY!!! I mean heavy hose watering.
I wish I had an open space with no trees so I could water normally! Yet...I LOVE trees.
Most of our property is open space although we have several huge trees in the front and one in the back. I wish we had more or at least one that shades the back of the house in the afternoon. Wen the afternoon sun hits it heats it up.
