You should not water plants everyday as plants don't require a daily watering and it could cause over watering of the plants which can do more harm than good.
Instead do a deep watering every few days or 2 to 3 times per week.
Also only water the plants in the early morning hours or evening hours after the sun goes down during the summer.
You need to create different zones, so plants with similar needs go together.
Water deeply one or two times a week instead of short spurts every other day.
Watering every other day for 15 minutes at a time may be convenient for you, but it can be disastrous for your plants.
Frequent shallow watering causes a plant's roots to grow near the soil surface, where they quickly dry out.
If you have a potted plant, slowly pour water to the base of the stem; let the soil absorb it and wait for the excess water to exit through the drainage holes of the pot.
This is to make sure that every single root of the plant gets water.
If your plants have yellowing leaves and old leaves, as well as new leaves that are falling at the same accelerated rate, you are overwatering.
In most cases, your overwatered plant will recover in 7 – 14 days if you follow the steps above.
If there was extensive damage, it may take longer.
But if there were enough healthy roots, it usually only takes about two weeks to see improvement.
If you are unsure how long to water new plants, aim for 30-60 seconds for small plants – longer for larger plants while moving the hose to a few locations around the plant.
Avoid watering when the soil feels moist.
