Gardenality.com's Answer · Hi Ray - In general, Muscadine vines are not heavy feeders. These natives are right at home in the soil of southern gardens. Muscadines tolerate a wide pH range so probably no need to adjust that. Never use manure of any kind at time of planting or around young Muscadine plants. Sawdust, cottonseed meal or peat moss may either slow down growth or damage or kill the plants. At time of planting, never put commercial fertilizer in the hole around the roots. At the most, and after plants have become established, a light application of a slow-release organic fertilizer after new growth has emerged in spring can be beneficial.
Hope this information is helpful,
