Since we cannot use sunscreen on plants, it is best
to place them in a protected area that gets no more
than an hour or two of morning sun when taking them
outdoors for the summer. Over the course of 10-14
days, gradually expose them to more sun until they
are able to tolerate the sun in the location where
they will spend the summer.
Just as there are
different plants for sunny gardens than for shade
gardens, do not expect houseplants that tolerate
very low light conditions to do well in a very sunny
spot. Make sure they have shade from the hottest
part of the day.

Most of your plants will recover, but until they
start to show signs of life again, be careful about
watering. It is very easy to overwater them since
their leaves are not functioning well. Too much
water leads to root rot, and they will not recover
from that. If they are in a location where they
receive rain, move them into a sheltered location so
that you control the water for now. Also, do not
fertilize them until they start growing again.
Plants actually produce different leaves in sun than
they do in shade or indoors. Shade leaves tend to be
larger and thinner, because a larger surface area
captures more sunlight. That enables them to produce
sufficient carbohydrates through photosynthesis to
support their growth. Sun leaves are often smaller
and thicker to prevent the kind of sunburn your
plants are experiencing.
