when should i water plants?

Answer 1

Root zone test: poke a hole in the soil and put your finger in. If the soil feels dry and warm, you need more water. If it is cold throughout the depth of the root zone, it is probably moist enough. Test the root zone moisture before and after watering for a given amount of time to know roughly how long to water next time, assuming conditions don't change drastically.

Early morning is generally considered the best time to conserve water with over head sprinkling systems. The wind is usually calm and the temperature is low so less water is lost to evaporation, more water will get to the plants costing you less and conserving water. This is best for this type of system.
If you water during the day when it is hot the plants will loose less water to evaporation so they will be less stressed. There has been crop research done showing mid-day irrigation has a higher yield per acre due to lowered water stress in high heat. This works best if you have drip or soaker hoses that deliver to the root zone. Over head sprinkling in a wind of more than 5 miles per hour distributes the water unevenly. If you have poor quality water, the mist which dries on leaves may deposit enough salt to injure them. Strong winds may carry the water away to neighbors' yards. Some water also is wasted by attempting to cover a square or rectangular area with a circular pattern. Many plants do not do well struck by lateral jets of water like impulse heads throw. Plants are adapted for rain that comes from above, evenly, not hitting one spot repeatedly for 20 minutes. Drip/soaker systems do not lose water to evaporation so the cost factor does not apply.
Midday is best for the plants but only if you use ground level delivery.

Answer 2

For outdoor plants, normally early morning or late afternoon. Never during the middle portion of the day when the sun is intense. The water can act like a magnifying glass and burn the plant leaves if applied during the hot portion of the day.

Answer 3

If the plants are outside, you do not want to water them in the heat of the day. You want to wait until the evening or early morning before it gets to hot outside. Depending on where you live, until late june it could be fine anytime...but rule of thumb is in the morning or evening. If they are inside, anytime is fine, unless they are right beside a window that gains a lot of warmth and then if that is the case, do it the same as outside.

Answer 4

Depends on the kinds of plants.

Answer 5

for most inside plants, once a week, if outside more often, depending on the weather!!! :) if it's in the cactus family, probably once a month!!!! i can't grow those, i can't NOT water!!!

Answer 6

Fish Emulsion (Fish Poop) is a organic fertilizer offered in shops. Aquarium water, if grimy, is a diluted type of this fertilizer. provided your aquarium is clean water, no longer salt it extremely is. Lake water is even more advantageous helpful ;-)

Answer 7

everyday at least once a day morning or before sunset
