Plant facts – why they need more water in summer

When it comes to caring for potted plants, one of the most important points to consider is your watering routine. One of the most interesting of all plant facts is that watering frequency and amounts can vary depending on the time of year. Here are some reasons why.

The process of photosynthesis

You may already know certain plant facts such as the way in which they make their own food. This is the process of photosynthesis and it requires sunlight, carbon dioxide and water. The plant combines these ‘ingredients’ to produce oxygen and sugars. During the summer months, plants are usually in their growing phase which means that they need extra ‘food’. Photosynthesis kicks into overdrive and it slows down once the plant becomes dormant. This is one main reason why you will notice that they do not need as much water in the winter.


One of the lesser known plant facts is that plants transpire too. They lose water through pores that are in their leaves. Just as we lose water through sweat and we feel the need to drink more water, it’s very much the same when it comes to plants. Since there is no way of slowing transpiration, it’s important to make sure that your plants remain properly hydrated.


Last, but not least, it’s important to note that the soil in the planter will dry out faster in the water months. This is because of normal evaporation. The warmer the weather, the faster the soil will dry out. During winter, you will notice that the soil will not dry out as fast which means that you do not need to water as often.

Not only are these plant facts interesting, but they will also help you take better care of your houseplants. By understanding their needs and how plants use water as part of their life cycle, everything else makes sense.
