Roses Extending Into Walkway & Yellow, Curly, Lemon Leaves

Question:

The bottom branches of my tree roses are extending out into the walkway. I’d like to prune them back so they don’t interfere with the entrance to the house. How far back can I prune them without damaging the tree rose?  

Answer:

  • Trees roses can be pruned back aggressively to keep them in bounds, just like a bush rose.
  • Before pruning, locate the point where the rose is budded to its roots. This is called the bud union.
    • With tree roses, you could have one or two bud unions.  One is close to the ground while the other is three to four feet off the ground. The desired rose variety grows above this point.
    • Any growth below the bud union should be removed and is referred to as sucker growth. 
  •   How much you cut the rose back is a judgment call on your part. It can be twelve inches to twelve feet depending on the situation. I’d cut it back to leaf bud that is pointing away from the walkway. If you strip away last year's leaves, you should find it on stems or rose canes.
  • In the spring and summer after flowering, you can keep the walkway accessible by pruning back these canes heavier than others. 

Question:

 The leaves on my dwarf lemon are a yellowish color, wrinkled, and some are torn. I’ve looked online as well as in some gardening books and don’t find an answer. How do I green up the leaves and what do I spray for the curly leaf diseases?

Answer:

 
  •  It’s common for lemon leaves to curl, turn yellow and sometimes even defoliate with the winter from the cold temperatures.
  • So, you do not have any type of leaf curl disease that requires treatment. Also, the ripped and torn leaves are not a big problem. Also, the leaves can take a battering with strong winds during major storms. You just remove the severely torn ones before the flush of spring growth in February or March.  The green leaf color returns when the days get longer and warmer.
  • I’d  encourage the new growth along with the green leaf color, lemons by feeding them with Citrus Food monthly, starting in February/March through October.
