Blueberries

You have some of worm nibbling on your leaves or it could also be slugs. Worms can be controlled by using an organic pesticide call Dipel and you will need slug bait for the snails. Don’t use either until you can identify which is causing the damage. Both usually work at night. The bigger problem, however, is your plant’s general health. Blueberries need extremely acid soil which no potting soil can do. You need to find find some very small pine bark — the kind used for mulch. Take your plant out of the pot and remove whatever soil you have and place into a larger pot – in your case a three gallon plastic pot will work fine. Place the pine bark into the soil about one thalfd the way up, place the root ball on the bark and fill the pot up to the top about 1 1/2″ from the top. Place in full sun and keep the bark wet. As the bark breaks down it will release the right amount of acid and your blueberry will be fine. Given your location, your native soil will never be acidic enough for your plant to be healthy. As the bush gets larger keep increasing the pot size until you get to a blueberry growing in a thirty gallon pot. Fertilize every 3 months with a fertilizer designed for azaleas. Many blueberry farms are going this route in recent years and it is working quite well. Just maintain good air circulation to keep septoria leaf spot at bay. Good luck!
