This is why outdoor potted plants are struggling

A garden expert has explained why gardeners are seeing outdoor pot plants struggle this summer.

Chris Bonnett from GardeningExpress.co.uk says excessive rain over the beginning of the summer months has led to waterlogged plants and poor blooms.

Waterlogging limits the amount of oxygen getting to the roots and stops carbon dioxide from diffusing away. This reduces the root function, meaning roots start to die off.

Potted plants, even those with good draining, are particularly susceptible to waterlogging.

Too much moisture can strip the soil of nutrients and minerals, can cause wilting, mis-coloured leaves, a lack of new growth, poor health and mossy green soil.

Chris also warns heavy downpours and freak hailstorms damage the plants further. He suggests moving plants if excessive rain is forecast and emptying saucers after the bad weather.

Chris Bonnett from GardeningExpress.co.uk said: “The weather has certainly played its part this summer and has really made gardeners think about what they plant and where.

“Nobody could have predicted the heavy downpours and while most plants have survived and are flourishing, those in pots have taken a particular battering.

“They can be susceptible to waterlogging and if they sit in saucers rather than raised on feet, then they continue to sit in excess water.

“There are steps gardeners can take to protect outdoor potted plants – for some this year it may be too late but it’s certainly worth giving it a try to salvage some.”

Here are GardeningExpress.co.uk’s tips for salvaging waterlogged outdoor pot plants.

Damaged shoots
Remove any dying or damaged shoots or leaves. This will encourage new growth.

Improved drainage

Make sure the drainage holes at the base of the pot are clear and if you need to, drill more in. The holes need to be free of roots or blockages so water can drain away freely. Think about putting the pot on feet, rather than in a saucer. This will allow water to drain more freely.

Check the soil

Check you’re using the right soil for your potted outdoor plants. The best compost depends on the plants you’re growing but always opt for peat free.

Repot

Try repotting the plant into a new soil mix. If you need to use the same pot, wrap it in a towel to help draw out some of the water.

Raised beds

If waterlogged pots become a persistent problem with the changing climate, consider building some raised beds in the garden. They will allow the rainwater to drain away naturally – and you’ll be able to create a stunning floral display.
