WHEN TO WATER VEGETABLES

WHEN TO WATER VEGETABLES

Ross Penhallegon, is a horticulturalist with Oregon State University, outlines how/when to water vegetables:

It is recommended that vegetables be watered during the early morning hours. It is cooler in morning hours, and this allows for more of the water to be absorbed into the soil, rather than some being evaporated. There is also less wind in the early morning hours, and so the hose/soaker hose pattern will not impacted by the wind.

The hours between 5am and 10am are ideal for automatic watering systems.

Watering during the late afternoon should be avoided because having the leaves stay wet into the night increases the chances of the vegetable plants becoming diseased. Increasing the probability of plants becoming sick if their leaves continue to be wet into the night, is also applicable to turf, and flowers.

If the plants are drooping during the late afternoon, it is okay to water them. However, some plants may become burned if the water remains on their leaves in the sunlight.

If the plant is a dull green, wilting, or growing slower than it should be, it is probably lacking water. If the surface of the soil is dry, that does not necessarily mean that the plant is in need of water. However, if the top 1-2 inches of soil a dry, a watering is probably needed.

There is also a time for particular vegetables, in which they need more water:

Beans: when flowering or pod is developing

Broccoli, cabbage, and other cole crops: when the head is forming and becoming bigger

Carrots/taproot vegetables: staring from germination up until harvest time

Corn: when transitions from tessel to silk and when ears fill

Cucumbers: when flowering, and the roots are developing

Eggplants: from the time of blossom and the enlargement of the fruit

Lettuce/leafy vegetables: Starting form germination until harvest time

Onions: When bulb is forming

Peas: When flowering, and the pods fill

Peppers: Starting from blossom and through fruit enlargement

Potatoes: From blossom until they hare harvested

Tomatoes: From the time they blossom and through the time when the fruit is enlarging
