Watering vegetable gardens requires good observation skills and the ability to improvise. Moisture needs vary between crops, and summer temperature fluctuations make watering an unpredictable art. Drip irrigation, sprinklers and harvesting rain water are all good methods that depend on geographical location and overall size of the garden. Does this Spark an idea?
Drip Irrigation
Drip irrigation has the advantages of low water usage and even moisture distribution through the soil. Supplies can be expensive for a large garden. Tightly spaced raised beds and small food plots are low cost to install and easy to maintain. The most common problem with drip irrigation is a clogged emitter. Installing a screen on the main water source is the best prevention. Malfunctioning emitters can be cleaned by removing them and applying a strong spray of water. Dismantle the system and store supplies every fall in cold winter climates to avoid damage.
Sprinklers
Overhead sprinklers are actually quite efficient in terms of water usage for a very large vegetable garden. They cover a broad area, raise overall humidity, and cost far less to install than drip irrigation. Use sprinklers early in the day. Wet foliage and cool nights encourage various diseases. Hot climate gardeners find an increased rate of evaporation using sprinklers, and more overall water usage.
Rainwater
Harvesting rainwater is a good technique for areas with unpredictable rainfall and for city gardeners coping with high water use charges. Rain barrels are not attractive, but can be disguised or hidden. Some municipalities may have regulations about harvesting rain water, so be sure to check local regulations. Screen rain barrels and gutters to prevent debris, especially if using drip irrigation in combination. Mosquito larvae may be a problem in certain places; however, a few drops of olive oil in each rain barrel is a non-toxic way of getting rid of them.
