What this plant likes (and what it hates)

Light

  • Best: Medium
  • Avoid: harsh midday sun if leaves scorch, or deep shade if growth gets weak

Watering

  • Rule of thumb: water based on the soil, not the calendar
  • Target: High watering habits
  • Common mistake: keeping the pot wet for days at a time

Soil and pot

  • Use a pot with drainage holes.
  • Choose a mix that matches watering needs.
  • If the plant stays wet for too long, use a chunkier mix and a breathable pot.

Common problems and quick fixes

Here are the issues people hit most often with Hydrangea.

  • Root rot risk: usually light change, watering swings, or a stressed root system
  • Leaf spots: often low humidity, mineral buildup, or inconsistent watering
  • Drooping: can be thirst, heat stress, or early root trouble
  • Brown tips: often overwatering, stale airflow, or splashy watering

A quick diagnosis checklist

  2. Look at the newest growth first.
  3. Inspect the underside of leaves.
  4. Confirm drainage and airflow.

If you are unsure, the fastest move is a clean photo of the underside of a leaf and a close shot of the damage.

Propagation basics

  • Best time: spring through early fall
  • Method: depends on the plant, but clean cuts and fresh water or airy mix matter most
  • Tip: slow propagation usually means low light or cold temps

Safety notes

If you have pets or small kids, treat toxicity seriously. Even mild toxicity can cause drooling or stomach upset.
