media is kept too wet, the roots soon
rot and the
plant starts to
wilt because it cannot
absorb the water needed. When this happens the beginner
usually adds still more water thinking the plant needs it.
What should we look for?
- A plant suffering from overwatering may appear to actually
need water. The leaves or stems will
turn yellow, sometimes dropping off. Someone seeing this might
believe that the plant needs water and add to the problem. But
once again, feeling the soil is the best way to avoid this.
When in doubt: Soil + dry = water. Soil + wet = don't water.

- One things that can happen to some plant (e.g. Christmas
cactus) is after the
buds have developed they drop
off the plant. Bud drop can be caused both by lack of
humidity or over-watering
What should we do?
Succulent plants like dryness. Some dry periods between
watering will maintain a

winter for most species withholding water completely is
the best method. Many plants will show signs of

the roots do not disintegrate.

watering until the plants actually begin to show signs of
Some species accept watering before they are ready to grow,
but it is very risky to attempt to push any plant into a
growth cycle with water too soon. There will be some
plants with indications of growth that are difficult to see
and obviously watering can't be postponed indefinitely. If the
plant has been kept completely dry through the winter and has
rested for over 6 months it may be safe to resume watering
without seeing signs of growth as long as the plant has
daytime warmth and enough sun.
- When plants are resting in their
summer cycle an occasional small watering will be fine for
most species as long as they can dry out between watering.
Some succulents and cactus plants will actually delay their
spring growth cycle until summer in more northern

when there is a circular growth of root mass at the bottom.
- By the time you notice that there is something wrong, the
media has already started to
decay and the plant has begun to
loose its roots. You need to
repot immediately, cut off all
dead and decaying roots and let plant roots drying and
for some day before to plant in a fresh substrate . Use a
coarser grade of media since this will allow more rapid drying

can try re-rooting. If your plant has signs of

pots can help to mitigate the effects of over-watering..
