# Summer Watering Guide: How Much Is Too Much?
Summer is peak growing season, but it's also when the most watering mistakes happen. Let's get it right.
## The Golden Rule
Water based on the plant's needs, not on a schedule. The same plant may need watering twice a week in summer and once a fortnight in winter.
## How to Check If Your Plant Needs Water
1. **Finger test** – Stick your finger 2-3cm into the soil. Dry? Water. Moist? Wait.
2. **Pot weight** – Lift the pot. Light means dry, heavy means still wet.
3. **Moisture meter** – A cheap tool that removes all guesswork.
4. **Visual cues** – Slightly droopy leaves often mean "water me."
## Watering by Plant Type
### Tropical Plants (Monstera, Calathea, Fern)
- Keep soil consistently moist but not waterlogged
- Water when top 2cm is dry
- Increase humidity with misting
### Succulents & Cacti
- Let soil dry completely between waterings
- Even in summer, every 10-14 days is plenty
- Never let them sit in water
### Foliage Plants (Pothos, Philodendron)
- Water when top 3-4cm is dry
- These are pretty forgiving either way
- Good drainage is key
## Summer Watering Tips
- **Water in the morning** – Allows excess to evaporate during the day
- **Water deeply** – Until water runs from drainage holes
- **Empty saucers** – Don't let pots sit in standing water
- **Check daily** – Summer heat can dry pots quickly
- **Terracotta dries faster** – Factor in pot material
- **Grouping helps** – Plants grouped together retain moisture better
## Signs of Over-watering
- Yellow, mushy leaves
- Soil smells sour or musty
- Fungus gnats
- Root rot (brown, slimy roots)
## Signs of Under-watering
- Crispy, brown leaf edges
- Wilting that recovers after watering
- Slow growth
- Soil pulling away from pot edges
Happy summer growing!
