Let the plants dry out before watering.
The roots of plants bring water and nutrients to the foliage when needed.
when the roots are dry they will search for moisture in the soil. By searching
for water and not finding it, the roots will grow to help out in the search.
As the roots grow and strengthen the foliage of the plants will also be able to grow and strengthen.
A plant that stays wet for longer periods of time will get lazy and week due to the water always being within reach and never has a need to grow or search for water. This may result in death to the plant. Some plants that are not in well drained soil and seem to only need water every week or so may look fine and may show no signs of any problem but, I dont think the plant is being grown to its potential.
