As gardeners old and young contemplate a new season of growing plants from seed we look at ‘Damping Off’

What is Damping Off

• The number 1 enemy of gardeners raising plants from seed.
• It is a disease that kills young seedlings at or just below soil level.  Affected plants wilt and die.
• It is caused by fungal activity.
• Some species are more prone than others.
• It seems to attack my seedlings in a humid atmosphere when sown indoors or in a cold frame.

What are the Cures for Damping Off

• Good hygiene is very important. Disinfect seed trays and use fresh compost.
• Keep part used compost in sealed bags.
• Use new pots on seeds that are prone to the problem like begonias and brassicas.
• A copper based fungicide watered on to the compost was the traditional cure or prevention.
• Cheshunts compound or products specifically for the purpose are sold at garden centres.

• Can be used on all seedlings whether edible or non-edible.
• Easy to use, dilute and water the solution onto compost before sowing.
• Repeat watering after the emergence of the seedlings.
• For transplanting, water seedlings with the solution before and after the transplanting.
• Suitable for organic gardening.

Other Damping Off Tips

• Prevent the problem by providing good air circulation.
• Make sure your soil mix is light and fast-draining.
