Even with veggie gardening we seem to be in uncharted territory - modifications to the climate are game changing, and I think we are all learning (the hard way) what may and may not work going forward. Growing tomatoes used to be easy for me - but the hotter, more humid - and this year, wetter - summers are causing so many attacks by so many different diseases that I am not sure what to do at this point.....and the weed growth (mostly from non-natives) is staggering...

Hoping someone will pipe up and offer more help than I can - but, yes, if it is really dry, nothing that you can do will have a fraction of the impact of what deep natural rains can do - spot watering just creates an opportunity for it to quickly disperse so that the area achieves some sort of equilibrium....

watering your foundation? Why do that? I'm on a slab btw.

So, think of your slab being built on a sponge: too wet, it expands and heaves upward; too dry, it shrinks and can't support any weight. We have to keep the moisture level in the soil around the house evenly moist, so one side isn't too wet, and the other side too dry. This causes concrete slabs to crack and shift. Maintaining steady moisture prevents the heaving and settling movement.

Watering foundations is common in Oklahoma, Texas, Missouri, etc., due to the soil.

My slab is cracked already too!

There are times of the year when one or the other door is hard to shut. We know it is because the soil has shifted. Moisture or lack of it is one of the factors that determine whether the soil shifts and how.

This especially applies if you have water restrictions to one day a week. (If you have a timer for your sprinkler system). Water in the middle of the night for half of what you think your plants need. Wait several hours, then water again. If it all goes on at once, it will not soak in as well on hard dry soil and some runs off. The first water will sink in and soften the soil and allow the next watering to be more beneficial. It's really hard to see your trees die. If it is allowed to let a hose run around them, then water a longer time, less often.

I'm in Texas, building a new house; I will not be planting any grass, whatever is there will be green if it rains; they had severe water rationing the last two summers here; only hand watering and drip irrigation; I want to have some plantings of xeric native plants and grasses with drip irrigation. No more azaleas and roses in this climate.

I'm going to let the yard dry out for a few days, only watering things that look like they need it (plus the beds around the house to keep the foundation happy). Then I'll start watering early in the morning, doing 1/4 inch, waiting an hour or two and doing another 1/4th inch. I'll do that twice a week and see how it goes.

Thanks again, it makes sense to go back while it's still damp and water more.

Now, there was another watering method I used, way back when I had access to some dirt and a yard, in order to water my little food garden.

I used one of those weep-hoses, put it under a layer of straw, and basically set it to "drip." The way I managed that was to turn it on full, in order to fill the hose, and then shut it off, only to 'crack' open the tap to a literal drip. Then I'd leave it on for 24 hours to give the ground a deep soak.

I would think that technique (minus the straw) could work for a lawn, too, seeing as how most people don't ever seem to think of using those hoses that way (people use them like any other watering-system: full on to flood their yard.)

and went through drought and water restrictions a few times, so I understand the need to water your foundation. I would not worry about the plants around the foundation----they are not as important as your foundation, although if it is that dry, you probably have no problems since the plants will not be really be sitting in water all the time with how dry everything is.

I did not worry about my grass. With several years of drought, keeping the grass in good shape just isn't going to happen. When (if) the drought breaks, work on the grass at that time. Seeding grass at this point is a waste of money. If it were me, I would be thinking of minimizing the grassy areas and moving toward drought-resistance plantings and rock gardens.....this water problem seems to be something that you will have to deal with more often than not. There are so many interesting things you can do instead of grass lawns.

As to the trees, I trenched around the drip line (the outermost area of the branches), then I watered into the trenches. This was advised by a tree specialist, and it seemed to work well at focusing the water where the trees could use it without just throwing water all around the trees.

Here's hoping that this drought situation doesn't continue much longer.

It'll poke holes in the lawn and make it look like geese pooped on it, but it will create holes that will allow water to penetrate into the soil.
