How often do I water my trees?

I have 2 plum trees, A walnut tree and an apricot tree in my yard. I know how to take care of my vegetable garden, but I don't know how to take care of my trees. How often do I water them? The weather is hot in california during the day it is 95 to 100 degrees.

How often do I water my trees?
Do NOT water your trees every day. Mother Nature does not water anything for "twenty minutes a day" unless it is living in the forests of Costa Rica.



You should water trees deeply when you water them. To get water into the root zone, lay a garden hose at the base and turn the water on very very slowly, almost so slowly as to not even be on. Let the water trickle for several hours. You could make a moat or dirt dam to keep the water in place soaking in at the base of the trees, but if you are accumulating much water in a puddle, you are watering too fast. If the trees are really big and mature, you could use soakers or sprinklers to apply water to the whole area under the canopy, in that case, leave them run for a while but not so long as to have runoff.



Most trees can not take as much water as people seem to want to apply to lawn grasses to make them look green all summer and consequently drown their trees. New plantings with reduced root systems from transplanting might need a little water once a week or so until they get a root going and thereafter only during hot, dry droughty periods. Consider the weather conditions and adjust accordingly. If it has been raining for a week, don't turn on the water. If it has not rained in a month, it might be about time. If you are not sure, dig a little hole near the tree and check it out to see how dry or wet it is below the surface. The trees will tell you if they are in trouble by wilting, scorching, or dropping leaves. If the plant wilts and you water it and it stands back up, it needed water. If it is wilting and you water it and it does not stand back up, that may be a clear indication of too much water that is causing root damage. I am not suggesting you wait to water until your trees do any of the above, but really it is not much different than your vegetable garden other than in the matter of scale. How well drained is your soil? Sandy soils are free draining and tend to dry out, where the clay soils fine particles tend to stick together and stay wet longer -- then be hard as a rock when dry.

You can not overwater something with the volume of water you apply at one time but you can overwater with the frequency of application. The idea is to water significantly when you water -- a good soaking -- then let it dry out some, just like natural rainfall or good tomatoes. Remember that tree roots are just bigger and deeper. Your trees should handle the heat fine as long as they do not get too-too dry on a hot afternoon. It doesn't matter to the trees what time of day you apply the water but you may lose more water to evaporation in the heat of the day. I would think you probably have some experts in your area that could provide you with more information on responsible water use--try your local garden center?

Reply:Water them every other day in the evening time when the temp has cooled down.
Reply:Only water the tree everyday if you want to kill it.



I guarantee you they will be dead in a few months if you water them every day.



Trees are VERY succeptable to root rot, which they get from being in soil that stays wet.



Trees planted ni the ground do not have to be watered at all unless they are specialty trees being grown in a drastically different climate than thier natural one.



Yes, you can water it once or twice a week, but it is not necessary. Unlike garden plants, trees have tap roots and long feeder roots that extend deep into the soil. So even if the top looks dry, they are fine.
Reply:water them at night when it is not so hot because its not good to water plants when its hot. and yea you can water them everyday if you want

deodorizers
