In the Northern Hemisphere, April or May is the best time for grafting, when buds are swelling and you know for sure that sap is flowing. This will give your grafts time to grow and heal. If you were to graft now while the tree is entering dormancy, the grafts have less chance of survival. You might be able to keep your scion sticks in the refrigerator until spring, although fresh is better. If you can gather scion wood in March or April, that would be ideal.
