Guide for Rescuing Gardens from Flooding and Waterlogging

The immediate aftermath of flooding and waterlogging can result in short-term effects that may dissipate over time. However, gardeners should be mindful of the more severe longer-term consequences that waterlogging can inflict on plants and gardens. As the duration of soil saturation increases, so does the severity of these problems.

The following guide, provided by Miracle-Gro, offers strategies to address these issues and mitigate the damage, ensuring that your garden remains enjoyable even during the summer months. Additionally, it includes long-term solutions that could prove valuable if instances of wet weather, waterlogging, and flooding become more frequent.

Identifying Symptoms:

Most garden plants, with the exception of those naturally suited to water environments like willows and bog plants, struggle to survive prolonged periods of flooding or waterlogging. The absence of air in waterlogged soil suffocates plant roots, leading to their decay and eventual demise. Initial signs of distress manifest in the form of yellowing, wilting, and premature dropping of leaves. Interestingly, these symptoms mirror those of drought, as the compromised roots fail to absorb water effectively.

Additional symptoms may include:

  • Shoots exhibiting signs of dieback, accompanied by wilting, indicating water scarcity due to impaired root function.
  • Bark peeling off stems.
  • Failure of herbaceous plants to initiate growth in spring, or initial leaf emergence followed by wilting and death.
  • Rotting and decay of bulbs.
  • Stunted growth, characterized by sparse foliage, and, in severe cases, plant mortality.

Short-term Plant Rescue:

Avoid walking on waterlogged soil, particularly heavy clay soils, until it has dried out sufficiently to prevent compaction and exacerbation of poor growing conditions. If traversal is necessary, utilize a plank of wood or portable path to distribute weight evenly and minimize compaction. Consider using products such as Miracle-Gro Moisture Control Decorative Pine Bark or Levington Decorative Chipped Forest Bark on paths and soil to facilitate easier movement and absorb excess moisture. Upon the onset of plant growth, administer foliar feeds such as Miracle-Gro All Purpose Soluble Plant Food to stimulate new root development and enhance overall plant vigor. For flowering plants, employ Miracle-Gro All Purpose Continuous Release Plant Food or other specialized feeds to sustain nutrient levels in the soil over an extended period, aiding plant recovery without risking root damage. Supplement with Miracle-Gro Bone Meal Natural Root Builder to promote the regeneration of root systems. Pruning of severely damaged or dead shoots may be necessary, although it is advisable to delay this until May or June, as plants may require time to exhibit signs of recovery. Paradoxically, thorough watering during subsequent dry spells post-waterlogging may be essential to alleviate drought stress, given the compromised root systems of affected plants.

Lawn Rehabilitation:

Similar precautions apply to lawns, which are equally susceptible to flooding and waterlogging. Refrain from walking on saturated turf to prevent soil compaction, subsequently aerating the lawn using a garden fork or hollow-tine aerator. Incorporating sharp sand into aeration holes can further enhance drainage. Periodic feeding with products like Miracle-Gro EverGreen Complete 4-in-1 can promote lawn recovery and encourage grass growth. Address areas of grass loss by reseeding with Miracle-Gro Patch Magic, a comprehensive solution containing grass seed, feed, and coir compost designed to facilitate robust grass growth under diverse conditions.

Grow Your Own Solutions:

Edible crops grown in flooded gardens or allotments should be discarded due to potential contamination from pollutants and sewage. Consider abstaining from ground cultivation for the current growing season due to lingering soil pollutants. In waterlogged areas, enrich the soil with organic matter to improve structure and enable vegetable cultivation. Alternatively, explore container gardening as a viable option for cultivating crops in less-than-ideal soil conditions.

Long-term Prevention:

Sandy soils typically recover more swiftly post-waterlogging compared to heavy clay soils, which tend to retain water for extended periods. Replenish lost nutrients in the soil through regular fertilization throughout the year. Enhance soil quality and drainage by incorporating bulky organic matter, such as compost or manure, into the soil. For heavy clay soils, consider amending with Miracle-Gro Lime Natural Soil Improver to facilitate drainage and enhance soil structure. In cases where soil remediation efforts prove insufficient, consider excavating a sump at the lowest point in the garden to facilitate water drainage. Fill the sump with suitable materials like brick rubble or stones, topping it off with gravel as needed.

By implementing these strategies, gardeners can effectively mitigate the adverse effects of flooding and waterlogging, ensuring the long-term health and vitality of their gardens.
