How often should I water my plants? Is a question we're frequently asked. To answer this you need to understand that without water a houseplant will die - This is a fundamental principle of all plants, it's especially important with houseplants as they don't have access to natural sources of water, and therefore depend completely on us to get it right.
That said most plant death is actually caused by too little water It's a fine balancing act and this guide will help you understand how to get it right.
Houseplant's are not keen on strict routine.Yes, you may hear your neighbour Jane saying she waters all her plants heavily every Sunday morning without fail, or Uncle Chris might swear his success is down to watering sparingly every Tuesday and Friday evening. However the fact remains that often such routines are unlikely to work long term and are only setting you up for problems later on.
Each plant has their own likes and dislikes when it comes to watering, even two plants of the same type could have differences. For example their location and their size will vary and effect how much water they need. Unfortunately the answer to this usually comes down to experience and practice.
There isn't a hard and fast rule to follow, it's a simple case of observing your plant, and interacting with it. By "interacting" we mean touching the soil surface and just below that to see if it is moist or dry. If the soil surface and the first inch below is dry, it's likely time to water your houseplant.
If the soil surface is still damp, no more water is needed. If your plant's not too big or heavy you can also pick it up; a pot or container which is heavily saturated with water will be much heavier than a pot which has completely dried out. There are also instruments you can buy which beep or light up when it's time to water again. Of all the methods and tricks people suggest the weight of the pot is by far our favorite one. Once you've done it a few times you will " just know " by it's weight how much water is left accessible for the plant and you will be able to gauge if it needs to be left alone, or if it needs a top up or a soaking.
Look for your particular houseplant in our Hub section of the website to understand its individual watering needs. When you've understood this, there are a few other things to consider because lots of different factors can influence how much the plant uses and therefore the time needed between watering's.
If the plant has fleshy thick leaves it's been naturally adapted to receiving less water, cacti and succulents for example. Too frequent watering here and you will be increasing the chances of rotting. On the other hand if the plant's leaves are thin or numerous then it will have less tolerance for under watering and will need more frequent watering.
There is less light in Winter and the temperature is cooler. This means the plant slows down because photosynthesis is less effective. Providing the room isn't excessively hot you may be able to reduce watering to just once or twice a month over the Winter months.
As the temperature and light intensity goes up so does the need for water. An increase in both of these variables results in a more effective level of photosynthesis which in turn needs more water. Plants which are in very humid locations will need less water than those in dry environments. As a general rule a large plant in small pot will need much more water than a small plant in a big pot.
This is because if the roots are filling the pot, there is less capacity for the soil to hold water because the roots are taking up the space. The opposite is true when the plant is small but in a large pot, in these circumstances much more water can be held by the soil so less frequent watering is needed..
Plant's in clay pots compared to those in plastic ones, will normally need more water because the clay is porous and water is wicked away from the soil in the pot.
Finally If you apply a mulch around the plant water will remain in the pot for a longer period as the mulch prevents the soil surface drying out as quickly. Sometimes it's easy to know when to get the watering can out as a number of houseplants are rather clever and tell you when they want water.
The Peace Lily in the photo below for example is very obvious. The picture on the right is the Peace Lily telling you it really needs water, the one on the left shows its now got plenty.Most however don't give such clear signs, but there are a few subtle hints you might be able to pick up on. Under-watering and over-watering cause very similar warning signs in house plants. If you have read the two lists above you might be forgiven for thinking we have made a mistake and copied the same signs into each.
Unfortunately it's no mistake, frequent under watering and over watering cause very similar warning signs in house plants! Even the Peace Lily example above sometimes isn't always that clear. If the Peace Lily has had too much water it also flump's over a little bit, which the novice may assumes means more water is needed, and before long he or she is trapped in a cycle of continuously over watering. What ever time suits you!
Well this is mostly true, a lot of house plants don't mind if you water them in the morning, afternoon or evening. However as a general rule its best to avoid watering any plant in the evening when it involves wetting their crowns or exposed stems. The idea is that if you do this, the water sits on the plant and when the temperature drops at night it can encourage plant rot or diseases. There are three main ways to water. Sometimes it's about what is most convenient for you, other times it's simply about preference.
However it's almost always best to water heavily once, then wait until the soil starts to dry out rather than little and often. This just involves watering from the top and allowing the water to filter through the pot by gravity. Although it's very quick it's less accurate than the other two methods below and so it's always best to have the pot sitting in a container or drip tray to catch any water that comes out of the drainage holes.
If your container has no drainage holes for excess water to escape from then you have no choice but to use this method, but be very careful you don't over do it!
The plant pot is sitting in a drip tray and you just fill the tray up.Eventually the water will be drawn up into the dry root ball. If the drip tray is quite small you may need to do this a few times until no more water is drawn up. Be sure to tip any excess water that is still in the tray away after half an hour to prevent rotting. You need to fill a lager container such as a washing up bowl, and then lower your plant pot into the water just so the water level reaches the top of the pot.
Bubbles will appear on the surface, and when they stop after a minute or so the root ball will be fully saturated with water and you can remove the pot from the water.
This method carries a risk of spreading diseases or pests if you are doing multiple plants in the same water. Make sure your plants are healthy, or ensure the sick one goes in last. The best water you can use on your house plants is the most natural - Rainwater or bottled water. However both of these options can be impractical or expensive in the long term, so tap water is the most commonly used type of water.
In the majority of situations tap water does not cause any problems, however if you live in a soft water area you need to carry out an additional occasional step to avoid issues. This is because soft water contains salt that will build up in the soil which will eventually effect the natural transfer of minerals and water into the roots.
To avoid this happening "flush" the pot once every couple of months. This just involves pouring in water to wash the salt build up out of the drainage holes. Be sure to provide fertiliser as you will also wash out nutrients in addition to the salt by doing this.
Watering is normally a quick and painless process, but sometimes there is something wrong with the soil which causes issues:. This is caused by a very dry surface soil. You don't typically get this unless your potting mix contains high levels of clay, for example if you have used garden soil instead of potting compost.
Or the soil is completely bone dry.The solution is straight forward however, just prick the surface with a fork or small trowel to break it up a little, then try watering again. This is almost always caused because the soil has dried out completely. This results in soil pulling away from the edges of the container creating a clear channel for the water to drain through, and the soil therefore does not have a chance to grab any of the water that is quickly passing by.
The solution is to follow the Immersion watering method above, if that isn't practical you can try Bottom watering. Over the last 20 years, Tom has successfully owned hundreds of houseplants and is always happy to share knowledge and lend his horticulture skills to those in need.

Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects. While evening water is discouraged , it can still be a better option than watering during the middle of the day. If you must water your plants overhead in the evening, try and do so on a breezy or windy night. Why we should not give water to plants at night? At the time of day even if there is a lot of moisture it can be absorbed by the sun but during the night time, watering allows the water that is sprinkled to stay for an extended period as there is no sun to absorb the moisture. This will surely result in fungi and bacteria. Less water is lost to evaporation, especially on hot, sunny days.

Water issues are a major concern around the country. Population growth and increased urbanization put increasing pressure on water supplies, making it increasingly important to use water more efficiently. Excessive irrigation inevitably results in leaching of water and fertilizer. This results in runoff that can end up in the ground or in surface water if it is not captured on site. Fertilizer runoff, especially nitrogen and phosphorus, can result in algae growth in ponds and lakes. Many growers face strict fertilizer runoff regulations. The best method to minimize runoff is to water more efficiently.
