In general most house plants are watered from the top, however,
watering plants from above may not be the best for a few reasons.
The leaves on house plants like the African violet may become
spotted or damaged. Of course it’s difficult to thoroughly water
plants from above without some water splashing on the leaves.
For most people, watering from the top down works fine. When
using this watering method it’s important to not overfill the pot
with soil. Keep the soil level about one-half inch from the top
of the pot. The best way to soak the entire root ball, soil and
root system is to fill the pot with water and slowly allow the
water to soak through the soil with the excess flowing out the
bottom of the pot through the drainage holes.
Another watering method is to reverse the process and water from
the bottom up. Simply take a saucer and place the plant on the
saucer. Then add water and allow the soil to soak up the water
until the soil media is damp to the touch or until you’re sure
the soil is completely soaked.
Make sure you DO NOT let the plant sit in water after the soil
has been complete soaked. When plants sit in water for long
periods of time the roots can become damaged. Roots need oxygen,
when submerged in water they can suffocate. Watering by method
the soil should be completely wet after a half-hour or so. If the
soil continues to soak up water add more water to the saucer.
When placing a plant in its growing container inside of a
decorative container or planter make sure the decorative pot does
not hold excess water and the growing pot sits in a puddle of
water. It’s best to use a piece of foam to raise the growing pot
off the bottom of the decorative container to create air space.
Another type of bottom watering system works well also, it’s a
wick type system. You’ve seen those ads on TV for more absorbent
paper towels that wick up or soak up water. A wick watering
system works very much the same. Special planter watering systems
are on the market but you can make it simply by using a cord
inserted through the drain holes with the cord in contact with
the water. As the soil dries out, water gradually soaks up
through the wick and waters the soil.
When watering houseplants use room temperature water or a little
warmer. You know how it feels when you get hit with cold water,
plants feel the same way. Cold water can cause problems just like
very hot water can, stay with room temperature for best results.
When it comes to watering your houseplants consider these three
points:
1 – Water when the soil feels dry to the touch.
2 - When watering, soak the soil and rootball completely, allow the excess to drain off
3 - Use water at room temperature or a little above, not cold.
Learning the art of watering will make your plant care much more
enjoyable, your plants healthier and last longer.
