Everyone always asks the same question - a very important and yet difficult to answer question - 'How much should I water?'. There is a simple answer to this questions - water deeply and infrequently. But what does that mean?
If you ever hand watered your landscape you might know that watering can be deceptive. We see the mulched looking soaked and the first inch of soil seems moist enough and we think it is enough.
There are many variables that need to be taken into account and some will be often specific to your garden - soil type for instance, others will include weather, rainfall, type of plants you have, etc. These will have to be assessed on case by case basis, but there are some general rules to follow:
- All plants need regular watering during the first year after planting, that includes drought tolerant plants.
- Be careful not to overwater — it’s the most common and easiest way to kill a plant.
- Overwatering means watering too often, not too much at one time.
- Know your plants - different plants have different needs and watering should be customized to their needs.
- If you have a sprinkler system make sure you water early in the morning - between 4-8 am.
- Make sure the water infiltrates the soil - which means water slowly, let is soak in.
