Hibiscus temperature range

The extent of the damage may not always be immediately apparent, as some signs can emerge gradually. So before you move them inside, it’s a good idea to prune hibiscus them back first. 

Trimming them back by 20 percent is ideal. So if you have young, small Hibiscus in pots then bring them indoors if there is frost.

To have a precise idea about the temperature of your Hibiscuses environment then it’s worth investing in a thermometer and humidity meter.

 

Hardy Hibiscus and Temperature

Hardy Hibiscus is also known as hybrid or perennial Hibiscus.

Instead, provide consistent, moderate watering, ensuring the soil is moist but not waterlogged, as damaged roots absorb less water.

The Hibiscus flower is an emblem of many tropical countries such as Haiti and Hawaii. Once night temperatures dip below about 35°F (2°C), more severe damage is likely to foliage and flowers.

They will begin to slip into a two to three month winter rest at this temperature while they restore their energy and will need to continue to receive bright light. Keep an eye on weather forecasts and be ready to take protective action with your tender tropical hibiscus varieties. Hardy hibiscus hybrids are the large-flowered perennial ones that vary widely in size and are derived from Hibiscus moscheutos (rose mallow); they can survive outdoors in temperatures as low as -30ºF/ -34ºC.

Tropical Hibiscus needs this temperature all year round. However, you can healthily prune them back up to 50 percent before the winter.

Not only will this save you some space, but this will stop the dropped leaves from littering your floor.

The most important thing is that wherever your plant is spending the winter, the temperature mustn’t drop below 55 degrees Fahrenheit (12 degrees Celsius).

Even in warmer climates, you might have to protect your outdoor tropical Hibiscus from unexpected cold snaps.

You can do this by using a frost cloth to cover it over until the temperature rises again.

It’s worth noting that mature Hibiscus are at less risk of frost damage than younger ones.

Their health and survival depend significantly on their environment, particularly temperature. This means that they will suffer when they’re not kept in their ideal temperature range.

If your hibiscus stays in temperatures below 50 degrees Fahrenheit (10 degrees Celsius) then this will impair its growth and blooming. 

It will start to drop its leaves and the chance of it producing flowers is very unlikely.

In the winter when it’s not blooming, Tropical Hibiscus can tolerate a minimum of 55 degrees Fahrenheit (13 degrees Celsius) without incurring severe damage.

But be aware that freezing temperatures will severely damage a Hibiscus.

This means they prefer warm, frost-free conditions. But for colder environments, it must be brought indoors for the winter. He owns hundreds of houseplants and prepares for the chili growing seasons yearly with great anticipation. Watch for these signs:

  • Wilting, drooping leaves
  • Leaves or flowers turning brown or black
  • Leaf drop
  • Failure to bloom
  • Dieback of branches
  • Slow growth

The severity depends on the temperature and duration.

If you have a window that’s facing south, then this is perfect.

Hibiscus plants can grow quite big in the summer. Just how cold hardy are tropical hibiscus? You can do this with extra mulch or a frost cover.
