Why Summer Pruning Matters
When your garden starts to look tired mid-summer, don’t blame the heat alone. Often, a little pruning can turn things around.
Pruning—especially deadheading—helps redirect your plant’s energy from seed production back into new growth and blooming. And during hot, stressful months, this gives your flowers a critical boost.
"Think of pruning as your garden’s summer refresh button."
Which Summer Flowers Need Pruning?
These bloomers benefit most from summer snips:
- Geraniums (Pelargonium) – Remove spent blooms weekly
- Petunias – Trim leggy stems back by one-third
- Marigolds (Tagetes) – Deadhead every few days for non-stop color
- Snapdragons (Antirrhinum) – Cut off spikes once the lower flowers fade
- Morning Glories – Pinch back to control size and encourage side shoots
Best for Zones 6–10, where summer heat often reduces flowering.
How to Deadhead: Step-by-Step
Deadheading means removing spent blooms. Here’s how:
- Identify the spent flower head – Look for faded, wilting, or browning petals
- Snip right below the bloom – Cut just above a leaf node or healthy bud
- Use sharp, clean tools – Avoid tearing or crushing the stem
- Repeat weekly – Especially after rain or extreme sun
Pro Tip: Wipe your shears with rubbing alcohol between plants to avoid disease spread.
Pruning Mistakes to Avoid
- 🚫 Don’t prune during peak midday heat – Early morning or evening is best
- 🚫 Don’t cut too low – Avoid damaging new buds forming beneath
- 🚫 Don’t leave jagged cuts – Use sharp shears for clean snips
Recommended Tools for Summer Pruning
- Bypass pruners – For clean, precise cuts on green stems
- Snips – Ideal for deadheading soft stems and flowers
- Disinfectant spray or wipes – Keep tools clean between cuts
We love Felco No.2 or Fiskars Softgrip for home gardeners.
