Hi,
Now is not the time to plant it, wait till the spring. keep it in a very cool place.(such as a garage. put the pot into a larger one with more soil around it .cover the soil with straw or something and around the sides of the pot) pick off the berries and plant it next spring. with a shovel full of peat moss in the hole. ( dig a hole twice the height and 1 1/2 times the width )don't add lime around this plant.
another thing is that you will need a different blueberry plant ( I am assuming it is highbush plant) for them to pollinated off each other. ( I have patroit highbush and Jersary) but any two different ones will do.
feritize 3 times during the growing season. ( compost, chicken droppings whatever just no lime) and pick off all blooms for 3 years~! you will want all the energy to go into the ground and for the plant to grow large. and you will have a huge supply of blueberries.
highbush blueberry can grow in a even 3 b zone. so you are quite safe
don't forget to use peat moss. you won't need anything in the soil (and in fact it is better if you don't add to your soil with anything else when you first plant it) and make sure it gets plenty of water and full sun
Hope this helps! :) Lynn
