Light needs
The plant should get several hours of direct sun, they may not flower much under winter
light. If the indoor spot you have selected is too dark, the plants will shed their leaves
after moving. After the leaves have been dropped, the plant will attempt to grow new
leaves which are adapted to the new light level. This level may be too low for the plant
to survive or grow well, and you may need to find another place. If this is not possible,
you may also try supplementing with artificial light.
Care must be taken when moving the plant outside in the summer. Any plant which has been
grown indoors can be overwhelmed by too much light. There are many physiological
differences between leaves grown in high and low light, and the plant's response to a
radical change in light regime is to drop the old leaves and try to grow new ones.If the
leaves appear bleached immediately after you move it outside, it is getting sunburned. The
bleaching means that the chlorophyll has already been destroyed, so by that stage it is
too late to acclimatize the plant. It is better to acclimate in all cases.
To acclimate your plant to the higher light levels of summer, you can limit exposure to
light in time and intensity. Put the plant somewhere that it will get a short period of
direct light in the early morning or late evening, when the light is less intense. You may
also put it in the shade of a tree or a lathe covered patio. As new leaves appear, give it
more light so that they are formed in the higher light level.
Fertilization
They have to be fertilized twice a week and watered constantly. With such intense inputs,
the roots could always find the resources the plant needed, they really don't care if they
are cramped or not.
Watering
Hibiscus should not be overwatered, but they are thirsty plants. I find that clay pots,
although esthetically pleasing, dry out much faster than plastic pots. It is important
that the plant not become water stressed.
