Force Rose Buds to Sprout: Pre & Post-Growth Tricks

Spring is the prime time for rapid growth of roses. For young roses, a proper germination treatment can help the plant to form a full shape and increase the number of branches faster. In this article, we will introduce two effective methods to promote germination: the treatment after germination in spring and the preparation before germination in early spring.

Tips for sprouting after spring germination

When the new shoots of roses have sprouted, topping (centering) is the most effective way to promote branching, especially for seedlings or grafted seedlings with sparse branches.

1. Topping of strong shoots

• If roses develop strong shoots (fast-growing upright new branches), they should be topped (by cutting off the top 1-2 pairs of leaves).
• This will break the apical dominance and stimulate the sprouting of lateral buds, resulting in a fuller plant.

2. Treatment of grafted seedlings

• The grafted buds can be topped when they reach 5-6 cm in length to promote branching.
• At the same time, it can activate the hidden bud points, accelerate the plant molding and early flowering.

Cautions

Topping other strong branches can increase branching but will delay flowering, so weigh this according to your needs.

Early spring pre-emergence germination strategies

The best time to promote germination is in early spring before sprouting, by pruning and physically stimulating more buds to sprout.

1. Retain appropriate branches

• Pruning can be done with more branches than normal, but if the branches are too long, it may be difficult for buds to sprout at the base.
• In this case, the following two techniques can be used:

2. Pressing down the branch

• Use a heavy object or a rope to press the branch down to near horizontal (45°-60° angle).
• Principle: To break the apical dominance and synchronize the sprouting of the basal and apical bud points.
• Example: The ‘Romantic Bic’ variety sprouted neatly at the base and grew vigorously at a later stage after being pressed.

3. Inverted flower pots

• A simpler method is to place flower pots horizontally to achieve a similar effect.
• Note: After the sprouting of the buds need to be corrected in time to avoid deformed growth of the branches.

Key reminders

No matter which method is used, the angle of the branches should be adjusted in time after the sprouting of new buds to ensure even illumination.

Combined with the appropriate amount of phosphorus and potassium fertilizer (such as bone meal or rose special fertilizer), can further strengthen the effect of germination.

Through scientific pruning and physical intervention, your roses will show more vigorous vitality in spring!
