The current format for Ask an Expert has been retired. It will be replaced by a new, but similar system called Ask Extension. This is a statewide initiative to upgrade the Ask an Expert system and details are still forthcoming.
In the meantime, and beyond, you may contact the Durham County Extension Master Gardener program directly to ask your gardening questions – We are experts, too! Reach us via email: firstname.lastname@example.org or telephone: 919-560-0528.
