If you live in Southern British Columbia, you’re no stranger to rainy days. The “triple threat” group of storms of this past October showed just how wet Vancouver’s rainy season can be, leaving detrimental consequences for many homeowners across the city.
When a lawn or garden experiences too much rainfall during a short period of time, they are prone to weeds, fungal diseases, and other issues which may threaten their health. Fortunately, there are a number of ways you can help your lawn or garden recoup after a long period of rain or a heavy storm, as well as preventative measures you can use to stop the damage before it happens.
How to Help an Overwatered Lawn
Lawns may appear underwater after a long period of rain or a heavy storm, as their soil becomes saturated after a certain amount of rain. This allows the water to collect in the low lying areas of your lawn, flooding the grass and leaving damage in its wake.
Before the heavy rainfall happens, you’ll want to turn off your sprinkler system to minimize the amount of water your lawn receives. After the rainfall, you’ll need to treat your lawn carefully until it recovers from the overwatering:
- Let your lawn dry out before you walk on it. Walking on wet turf can make the damage worse.
- Remove any leaves, twigs, or other debris from your lawn to reduce the chance of fungal diseases.
- Fertilize your grass if it appears yellow. Floods can drain your grass of its nutrients, but fertilizing your lawn can help it recover more quickly.
How to Help Plants Recover From Rain Damage
After heavy rainfall, your plants may appear flattened and damaged. Heavy rainfall can cause damage to plants, but generally they retain structural integrity despite the severity or length of the storm and will typically return to their upright position within a few days.
Many plants can survive a storm without long-term negative effects, but others may suffer from severe damage. Cut off the most severely damaged parts of the plant to make room for new branches and leaves to grow. Plants typically sustain damage after heavy rainfall if they are over fertilized or receive little sunlight, so run a soil test after a heavy storm to determine how you can best prevent damage in the future.
Preventing Damage From Heavy Rainfall
The best way to keep your lawn and garden looking healthy after a storm is to prepare it well before the rain begins:
- Keep your gutters and drains clean to prevent flooding in certain areas of your lawn or garden.
- Raise your garden beds to help reduce the chance of flooding in these areas.
- Aerate densely packed soil to help it drain more efficiently.
- Keep your lawn at an ideal height – longer grass traps more water than shorter grass, so mow your lawn before a severe storm.
