Overwatering

House Plants

• Ensure all plants have good drainage around them. House plants should be planted in pots with drainage holes and not in pots where water can rise to cover roots.
• If your house plant is already showing symptoms, remove it to outside or to a sink and let all water drain from the pot for an hour or two. Prune away very yellowed leaves. Re-pot in a pot with good drainage holes and place on a pot saucer to prevent water damage to surfaces where plants are set.
• Use the Gro-Sure Houseplant Watering Indicator to ensure you only water your houseplants when they need it.

Garden Plants

• Some plants such as willows are tolerant of being in saturated soil for long periods. In the garden check that only plants that are tolerant of poorly drained soils are planted in areas of clay soil or where water pools.
• If you have affected plants you can either try and improve the drainage in the area or by replanting in a more suitable soil. When replanting dig the plant out taking the largest possible root system. Place on a Hessian or other porous sheet, wrap and allow water to drain for 2 hours then plant in new better drained situation.
• Drainage can be improved by spiking and aerating compacted clay soils, or adding and mixing in sand and compost mixture, and turning over thoroughly. This is difficult in areas that are already planted out as it may damage root systems. It is better done prior to planting or re-planting.
