ADVICE AND RESOURCES FOR GARDENERS
WATERING TIPS FOR GARDENERS:
Watering by hand is more and more a lost art, especially as gardeners have come to rely on automated watering systems. Yet knowing the ins and outs of watering by hand gives gardeners invaluable insights into what is arguably your most important gardening tool of the summer and one that will even help you manage your irrigation system more effectively.
Established plantings need deep, infrequent watering. Most plants require an inch of water per week: rain plus hand watering or irrigation. Applying that inch of water in one deep watering will encourage deeper rooting, which leads to stronger, healthier plants. Shallow, infrequent watering, on the hand, will lead to shallow root systems and high water loss through evaporation.
Slow and steady. In the same way that a slow, steady drizzle benefits a garden the most, when watering by hand, apply water slowly and not in a deluge. This means setting the hose to a gentle spray and going over the same ground multiple times to ensure water has time to reach the roots, rather than running off. At Rachel’s Garden at Mulford Farm, for example, hand watering should take up to an hour. Note that in our other gardens, most of which have drip irrigation, we still need to hand water newly planted materials until their root systems are well established.
Focus on the root zone. Remember that it’s the roots that need access to water, not the leaves. Wetting the foliage is a waste of water and can promote the spread of disease or unsightly funguses on foliage.
Use a spade to check whether water has reached the root zone to a depth of 12 inches. Perennials, shrubs and trees concentrate their roots in the top 12 inches of soil, and the best way to know that you’ve watered to that depth is to dig and check. To get a feel for how the soil ought to look when watered properly, push a spade into the soil before you water and again after you finish. You’ll begin to see the difference between dry and moist soil, and to recognize about how long it takes to water by hand and get the soil moist to a depth of 12 inches. In addition, you will gain insights into which parts of your garden benefit from rainfall more or less than others. At the Millstone Garden, for example, the beds closest to Main Street rarely receive as much rainfall as those at the back of the garden, because a large shade tree on Main Street acts as an umbrella deflecting water away from these beds. So some days, the front beds require hand watering when the back beds do not.
The best time of day to water is early morning before temperatures begin to rise. This gives the plants a good supply of water to face the heat of the day. Early morning also tends to be a time of lower winds and thus reduced evaporation. Very late afternoon is also sometimes satisfactory, but generally within 2-3 hours of nightfall so that foliage has enough time to dry. Remember that water that sits on leaves overnight can damage foliage and allow plant diseases to flourish.
BASICS OF SOIL TESTING FOR GARDENERS:
Using a spade, shovel, or even a bulb digger, collect a series of small soil samples from about 3” to 6” below grade (so that you are below any mulch or other additives) and mix together all of the samples for a discrete area you wish to test. Air dry the sample for 24 hours and then send it to a lab for testing. The University of Connecticut uses a Modified Morgan test whereas other labs may use the Mehlich 3 test, which overestimates some micronutrients in northern soils (it was designed for Georgia). Here is the link to UConn’s website with detailed directions and forms for submitting soil samples for analysis: http://www.soiltest.uconn.edu/sampling.php
