Do you know that you can make roses grow bigger than the normal size you’re familiar with? Well, in this article, you’ll be enlightened on how to do that.

When cultivating roses (Rosa spp.) for huge blooms, you must first select the suitable rose class, followed by a variety known to produce enormous flowers. According to the Santa Clarita Valley Rose Society, hybrid tea roses produce the greatest bloom diameter.

California Dreamin, with 5-inch flowers, Chicago Peace, with 6-inch flowers, and Medallion, with roses with an average diameter of 7 inches, are among the cultivars in this class that reliably produce huge blooms.

Grow ‘California Dreamin’ in USDA plant hardiness zones 6b through 9b for the greatest results. Zones 7b and up should grow ‘Chicago Peace,’ whereas zones 4b through 9b should grow ‘Medallion.’

The size of the flowers you get from a large-blooming rose depends on how well you care for it. If your goal is to grow the largest blooms possible, keep in mind that this will result in fewer blooms per plant, as it will necessitate some early-season pruning.

How To Make Roses Grow Bigger

The following are various methods adopted to make roses grow bigger.

Set A Suitable Irrigation Schedule

Water the rose bush regularly, but not excessively, to keep the soil moist but not waterlogged. You may only need to water once a week during the hot summer months.

Use a well-balanced fertilizer

Fertilize the rose to encourage it to grow strong canes and produce huge blossoms. Use a 10-10-10 fertilizer at the rate recommended on the label when the new foliage is 10 inches long.

Remove any stems that are crossing or have a bad shape

Pinch off any stems that are developing toward the plant’s center, downward, or appear to be on the verge of crossing over another stem. Only the strongest stems should be kept.

Fertilize with a high-phosphorus mix after the buds have formed

When the stem begins to set buds, fertilize it with an 8-10-8 formula to promote flower growth. Use the fertilizer package’s recommended rate. When the stems are long but the buds haven’t cracked open, fertilize the rose once more.

Use a 0-50-30 fertilizer at half the rate advised on the label to prevent more leaf growth and support the rose bush to focus all of its energy on blooming.

In the early spring, hard pruning is recommended.

Heirloom Roses recommends pruning the rose bush in January to create firm canes to support the weight of the enormous blooms. Cut the shrub down to 18 to 24 inches tall in the spring.

The further you prune back the bush, the fewer blossoms you’ll see, but they’ll be bigger. Remove any dead or broken canes, as well as any that are pointing into the bush’s interior.

Spent Blooms Should Be Deadheaded

When the rose bush’s blossoms have faded, deadhead it. Dead roses should be pruned down to the first developed leaf cluster, which has five leaves. Follow the stem back till it becomes thicker and cut there for developing huge roses. It doesn’t matter how far back you cut the stem as long as there are at least two mature leaflets left.
