Transplanting An Old Tree Rose & Pruning Fountain Grass

Question:

I have an old tree rose in a wine barrel that’s falling apart. I’d now like to plant it in the ground. The front of my house faces west, but there is a partially shady location in the backyard. Where would you suggest planting it?

Answer:

  • Either site would be okay, as both locations would receive at least six hours of direct sunlight per day. That being said, I’d prefer the semi-shady location.
  • This location, more than likely, is protected from the afternoon winds during the summer months. Mature tree roses are susceptible to breakage, as they are top-heavy, especially the Hybrid Tea and Grandiflora types. They can get very top-heavy as the growing season progresses. After each flush of blooms, reduce the height and remove some of the inner canes. This helps increase the airflow through the canopy.
  • Afternoon shade prevents the exposed stem from sunburn during hot temperatures. This can cause the bark to crack and peel and can be an entry point for flat borers. They’re also not adequately supported with a stake. Hence, the location that receives the lesser amount of wind is more desirable.
  • When you remove what’s left of the barrel, you’ll find little soil and a solid mass of roots. The roots will continue growing in this circular pattern unless you score the root ball. To prevent this, you should trim the root ball by removing one to two inches off the sides and four to six inches off the bottom at planting.
    • The planting hole needs to be extra-large, and you should generously amend the backfill with organic matter. The original root ball should be one inch or more above the final grade to prevent it from sinking and being buried too deep.
    • The next step is to add a new stake(s), as the current one is too short. The stake(s) has to anchor the rose in the ground. I’d select one that is two inches by two inches by five feet, and it’s driven six to eight inches past the root ball. The stake should be under the grafts, which are about thirty-six inches above the ground.
    • A six-inch high watering basin is then constructed around the rose. It should be and extend from the trunk to the drip line. The water basin ensures that all the roots get wet when you water. And finally, fertilize with Rose Food often.

Question:

My Fountain Grass has turned brown. How far back can I prune it? Also, when will it be nice and full again? 

Answer:

  • Fountain grass is pruned down to the ground. The new growth will appear at the clump base as the days get longer and warmer. After Memorial Day, the growth rate will accelerate, and the plant should reach full size by mid-July.
  • You can encourage the new growth with a hand full or two of an organic All-Purpose Fertilize in March.
