How Does Temperature Affect Plant Growth?
Providing optimal temperature for your plants
While many houseplants will survive with a relatively wide temperature range, always check your plant’s specific needs for its proper growth. As many house plants come from tropical areas, few will be able to deal with long periods of very low temperatures. Similarly, extended hot weather could cause some plants to dehydrate quickly and wither.
- Flowers die quickly.
- Yellowing leaves and falling.
- Lower leaves falling, leaves wilting, and edges turning brown.
- The effects of too much heat
- Wilting leaves.
- Flowers fade rapidly.
- Edges of leaves dry up and become crispy.
- Constantly needing water.
- Active growth in winter becomes different from what you see at other times of the year.
- The effects of too little heat
- Curling of leaves.
- Leaves fall off.
- Rarely need to water the plant but the soil is constantly damp and develops mold or fungus.
- Very little growth.
Always research or check out the basic growth conditions including the temperature requirements of plants that you plan to buy. If you have a plant that you cannot identify, the safest range is between 12-24 degrees Celsius, which suits the majority of houseplants.
Where To Place Houseplants In Your Home
1. Cold Drafts
2. Away from a window
3. Window sills
4. Hot & dry areas
5. The ideal spot: Short distance away from sunny windows
Know about Normal Temperature variations
- Day tonight temperature: Changes of about 5-10 °C are normal for most plants,as that is what they would experience in nature.
- Seasonal temperature variations: It can be experienced by most plants, even inside our hot summer homes; in winter, this often leads to a reduction in growth. Some plants adapt to cold climates by becoming dormant in winter, these will need to be moved to an unheated area at this time of year.
The Final Words
The effect of temperature on the growth and development of plants varies as per plant species. Every plant has a minimum, maximum, and optimum temperature for its growth. So whether it is extreme heat or cold, the temperature does affect plants and their growth. This is one of the reasons why it is important to check a plant’s hardiness and see if it is compatible with the particular growing zone.
