Yes! And it’s a very important question: all citrus trees are grafted (grafting is a method of asexual plant propagation where the tissues of one plant are fused with another plant).
Above the graft is good, viable foliage. However, if stems, suckers and foliage begin to grow from the grafted portion (bottom of citrus tree) the tree will produce sour citrus if not pruned or cut off. You must prune growth from grafted area to avoid souring fruit. Trim as desired or needed preferably in the warmer months. (Read more on how to prune your citrus tree here)
Azalea care
To all you proud azalea owners, do not trim your plants late in the fall.
Your azaleas may have some long runners on them and you may be tempted to trim them back, but beware you may be trimming off potential buds that will develop into beautiful blooms this spring. Be patient and trim them after they have gone through their bloom stage.
Also, for those of you considering planting azaleas in time for the spring blossoms, November December is the perfect time to plant them. Azaleas are cold hardy and their bloom is breathtaking and hard to beat come spring time!
