Most modern rose varieties should be pruned in what months?

Pruning modern rose varieties is best done in February and August. This timing is optimal for several reasons.

In February, pruning occurs just before the active growing season begins, which typically starts in early spring. This allows for the removal of any dead or diseased wood and encourages healthy new growth as temperatures start to rise. Pruning at this time helps to shape the plant and promotes better air circulation, which can reduce the risk of fungal diseases.

The second pruning in August allows for deadheading or the removal of spent blooms, encouraging a second flush of flowers before the onset of fall. This late summer pruning could also involve light shaping and the removal of any excessive growth, ensuring that the plant remains healthy and manageable as it prepares for the winter months.

Timing is crucial for roses, as improper pruning can lead to reduced flowering and health issues. The other choices do not align with the traditional horticultural practices around rose care and growth cycles, making February and August the most effective months for pruning modern roses.
