The campaign by Flood Re comes as homeowners may be heading back out into their gardens over the bank holiday weekend.
The heavy rains of recent days and weeks could have left gardens in a state, and some people considering the risk of flooding in their area.
Bosses of the insurance scheme said people spent hundreds of pounds on their gardens, but one in eight had experienced the impact of flooding in their green spaces.
Many were oblivious to the risk, but properly managed, domestic gardens could channel, absorb and store large quantities of water, limiting the risk to property and the local area.
Environmental designer Ed Barsley said: “What’s positive to note is that there are a variety of practical and cost-effective measures that garden owners can take to save themselves emotional and financial stress further down the line.”
Ideas include choosing a variety of plants such as willow, water mint and astilbe, as well as slowing the flow of water into the garden during heavy rain.
