Lifelong Green
Mid summer is when Houston begins its tropical storm season. While the blackened skies and the sound of afternoon rain make an excellent backdrop for an afternoon nap to many people, to me, the afternoon thunderstorms conjure up images of flooded yards and drainage problems.
Pools of water in a yard are certainly unsightly, but proper drainage
is of greater importance than just appearances. A landscape that drains
poorly can create many problems, ranging from plant disease, soil erosion
and even structural damage to a foundation.
Solutions range from simple
to complex.
Soil improvement and leveling may be a first step. Lawns
and beds can become compacted over the years, and aeration is oftentimes
excellent for easing slight drainage problems. Mulch needs to be attended
on an annual basis.
Beyond that, subsurface drainage with underground
collection pipes, catch basins and channel drains are used to direct
water to the street.
Sometimes problem areas can be dug out and filled
with crushed rock, allowing water to seep into the ground, all the
while providing a landscaping accent.
Drainage is as important an issue
as irrigation. Installation of a system requires significant planning
and knowledge. Some municipalities in Houston even stipulate that a
drainage system be designed by a licensed engineer or landscape architect.
Next time we have a significant rainfall, observe your property carefully.
You might even want to take some photos. We can talk. And next year
at this time, when everyone else is dreading a backyard that’s flooded, you’ll be getting ready to enjoy a nap during the thunderstorm.
See you in the garden,
