dry air

What you’re seeing

Crisp or browned leaf tips/edges, leaf curling, buds that dry before opening, or rapid evaporation from saucers. Indoor readings commonly below 35–40% RH (relative humidity).

What it is

Air that’s drier than your plant prefers—common in heated or air-conditioned rooms. Dry air accelerates water loss from leaves, stressing thin-leaf and tropical species.

Is action needed?

Often yes, especially for humidity-loving plants. Improving local humidity reduces tip burn and bud drop.

How to confirm

  • Hygrometer reading: RH consistently < 40%.
  • Pattern: Tips/borders brown first while mid-leaf stays green; soil moisture may still be fine.
  • Seasonality: Worse in winter with heating or in hot, windy summers.

What to do

  1. Hydrate the root zone first. Keep watering consistent; humidity helps but doesn’t replace watering.
  2. Cluster plants. Grouping creates a localized moist pocket.
  3. Use a room humidifier near plants, set to 45–55% RH, cleaned weekly.
  4. Tray method: A wide tray of water + pebbles under (not touching) pots increases local RH.
  5. Reduce leaf stress: Bright indirect light; avoid midday sun and strong fans.
  6. Avoid frequent misting for thin leaves—it raises RH only minutes and can spot leaves in strong light.

Prevention tips

  • Choose plants that match your home’s baseline RH.
  • Keep plants away from heat/AC vents, radiators, and door drafts.
  • Focus on ambient RH (humidifier, trays, grouping) and steady root-zone watering; avoid changing pot size just to address dry air.
  • Salt buildup from fertilizer/very hard water can mimic brown tips—leach the pot.
  • Under-watering causes similar crisp edges—check soil moisture pattern.
