When I was in the middle of therapy from my hip replacement, my therapist said, “Eric, I have been disappointed in the 3-year-old roses I have around my house. I want to pull them out and get something new.”

First, I told her, “It’s expensive to replace all the roses with something else, and you don’t know that you would be any happier with any other plant you may put in the ground;”

I asked her to be patient, and we’d develop a program to get the flowers to produce the blooms she wanted.

The drought has been hard for many plants. My roses also had a hard time. Rose shrubs in my front yard have not bloomed as well as I hoped. The roses I have are a dark pink Rugosa Rose, and two shrub roses are still a good green.

Don’t fertilize roses in the middle of September. Even when the number of blooms doesn’t match your expectations, there can be significant problems with fertilizing this time of year.

We need pruning because fertilizing is not always the answer to getting more flowers on roses. 

Before fertilizing anything, we need to discuss some serious issues. To fertilize roses, you need to know that the cut-off date is the last day of July.

Fresh new growth on your roses will lead to more damage to the health of the rose once the frost hits. From March to the end of July, you can fertilize your roses. 

Hybrid Teas, Floribundas, Shrubs, Knock-outs, and species of Roses vary with the nutrient amounts that they will require to some degree. The Climber and Rambler Roses are vigorous growers and should be fertilized more.

Before fertilizing any roses, look at where you planted them and do a soil test. Most roses are very demanding in their requirements. Roses need six solid hours of sunlight during the growing season to do well.

Second, since roses are heavy feeders, the best conditions to plant your roses in would be rich, organic, moist, well-drained soil.

March to May and early September are the best time to plant potted roses. Plant bare-root roses during most of the year.

Formative pruning is an attempt to encourage the strong development of a multi-stemmed plant.

Strong shoots form close to the ground to create a balanced framework of branches and encourage flowers.

Remove damaged or broken shoots and cut back any shoots growing across the center. 

Prune back healthy shoots within three to six inches above ground level, cutting to an outward-facing bud.

Proper pruning also encourages good flower development at the right time of year. Rambling and Climbing Roses prune early to middle fall. October is an excellent time to prune these roses.

The balance of the rose varieties should be pruned in late winter and early spring for the best blooms.

The pruning of your rose changes from shoot production to making an open-centered plant.

Good air circulation around the branches will reduce the chances of developing the diseases that a poorly pruned rose can have. Good pruning increases the strength and health of the rose and bloom production.

Prune your roses annually. Roses are heavy feeders and cannot neglected.

The nitrogen, potassium, and phosphorous nutrients all have their purposes. Top dress the soil around the rose to form a ring with about one handful of Rose food in March or April before the leaves have formed and hoe the fertilizer into the soil. 

In June, do about the same kind of top-dressing as in April. From April to July, fertilize with a liquid fertilizer application once a month. Standard water-soluble rose food will answer the nutrient needs of the rose.

Those hose applicators make fertilizer application easier. If you can use this kind of applicator, do so.

If you want to raise show-stopping roses, hand spray a lighter nutrient solution of this rose fertilizer. The foliar application will allow the blooms to take off.

The queen of the flowers, the rose, is one of my favorite topics. If you have any questions, please email me at ericlarson546@yahoo.com.

 In time, I shall leave links to my blogs on my website www.ohiohealthyfoodcooperative.org. Have a wonderful stroll through your gardens this week.
