Now, you might be wondering when is the best time to start cutting off those dead blooms. The answer is, as soon as you notice them! Hydrangeas typically bloom in the summer months, and it's essential to remove the dead flowers before the plant starts to produce new ones. Use a pair of clean, sharp scissors or pruning shears to make the cuts, and be sure to cut just above a leaf node to encourage new growth.
But, don't just stop at removing the dead blooms - take a closer look at the plant's overall shape and size. Are there any overgrown stems or leggy branches that need to be trimmed back? By taking the time to prune your hydrangeas, you'll be rewarded with a fuller, more balanced plant that will continue to thrive throughout the growing season.
