Visualizing the Value of Watering in Drought Conditions

Here is a picture of our back yard taken on July 22, 2012, after weeks of drought conditions in Chicago.  We water as noted in the previous post (make sure you check that out) and you can see that the lawn and garden are green and healthy.   Notice the difference between our yard and the area in the top left portion of the picture which is not watered regularly.

Watering In Drought Conditions

So this is the next installment of Gardening in Drought Conditions.

I thought some additional information on watering might be helpful.  Let’s say its 75 degrees outside-go with me on this…we loose about an inch of water a week at that temperature, so we would need to give back an inch of water a week, either through rain or watering, to keep established plants pretty healthy.

So how do we know what an inch of water is? To monitor this put out a rain gauge. You can get a really fancy wireless gauge that has lots of buzzers and bells at Home Depot.  I use the caveman version, a cat food can.  The idea is to leave the receptacle out in an area that is getting rain or sprinkler water so you can measure how much is distributed over a period of time. Make sure the receptacle is in a place that gets an average distribution of water so it’s a good estimate of what is falling on the entire area.  If you are watering an area that has lots of plants put the receptacle on the ground under foliage to measure the water actually getting down to the ground and not just on the leaves.

We put out a traditional arcing sprinkler, the kind we used to run through when we were kids.  It arcs a full 180 degrees and we leave it on for an hour or so on the lawn.  We find that this gives us about a 1/4 inch of water.  This means we would need to water for 4 HOURS to replenish the water loss over the course of a week. (It’s ok to soak the ground once a week so the water penetrates deeply.)  Every yard and every hose is different so use this method to determine what works for your yard.

So that’s at 75 degrees, a lovely temperature.  If the temp goes up the water loss increases…for every 10 degree increase in temperature the water loss increases by 1/2″.  So at 95 degrees it’s 2″ of water that needs to be replenished. So we would leave our sprinkler on for 4 hours twice a week, pretty easy math.  This is doable in most areas so we can have healthy gardens even in this weather.

So in summary at 75 degrees replenish 1 inch of water a week, for just about everything. If you have non-native trees they need more like 2″ per week.  If the temp goes up 10 degrees the additional water needed is 1/2 inch.  Newly planted materials need more water more often so always check the roots and the soil to make sure it is moist.

Any questions let me know!


btw-next post will be plant ideas for drought conditions.

Saving Plants Through a Drought

Recently I was asked, “How do you garden with these high temperatures and drought conditions?”  For existing gardens suffering under this brutal heat, you can save your plants with the proper watering.  Even if you have watering restrictions you can give them enough to get them through these hot days.

Any plant that is visibly wilting will want a gentle stream of water at its base for several minutes, up to even an hour if needed.   The goal is to soak the ground around and deeply under the plant keeping the roots moist and prompting them to search for water deeper into the ground where they are more likely to find sustaining moisture.

Maintenance watering for large plants and shrubs should be focused at the base of each plant.  Use a hand held sprayer on a “shower” setting that does not disturb the dirt, but allows the water to collect and penetrate into the ground at the base of the plant.  You may need to make repeated applications to insure enough water has made it into the ground.  If you use a sprinkler, leave the water on long enough to soak deeply into the ground.  In either case, if water starts to pool and run off stop the flow, let the water soak in, and turn the water back on for additional watering.

The goal whenever watering is to make sure the ground around and under the root ball of the plant is wet.  Whenever there is uncertainty as to whether enough water has been applied, use a trowel or shovel to gently dig into the soil at least 3-4″ to check if the soil is moist.  If not, you need more water.

Water plants early in the day so the leaves have time to dry.  If you have time restrictions, you can set timers to allow the water to run even when you can’t hold the hose.  If you are limited to certain days for watering, make sure you apply enough water to keep the soil moist during your off days.

These are general techniques.  If you have specific issues, questions, or needs, please leave a comment and I’ll offer any help to your garden I can.  I look forward to hearing from you.


btw – In the next post I will include some specifics on water requirements and application for various situations.


In my excitement I neglected to even introduce myself.  For now, know that I am Gina.  I have decent size city lot in Chicago, on which I have built a haven.  I have been consumed, in a good way, by my garden for the past 5 years.  I hope what I have to offer will inspire you to create something extraordinary.

I will show you the evolution of my garden and all the associated projects.  I also want to be a resource for you so ask questions, give me suggestions, and we will work together.  Soon I will add an “about me” page with more background info on me.  Until then let’s blog!


This is it. The Beginning.

You can say you were here when it all started.  The flowers, the embellishments, the excitement, the wonder and awe of life through my eyes.  Spend some time with me at the Keeler Gardens.

So we’ll start with a bunch of wonderful pictures, mostly taken by Ed.  That’s my husband, and website manager, and all around worker bee.  He does a lot of my grunt work so you will get to know him as well as me and our garden.

Enjoy these snapshots and please comment.  Come back often as I will post and talk and offer up whatever I can to inspire you to create a little wonder in your life.  If there is anything you want to see or know, email me at
