How to Water Tropical Plants in Greenhouses

Tropical plants are adapted to warm, humid climates where they have access to plenty of direct sunshine. So, if you would like to keep tropical plants at home, you cannot just keep them inside your home or plant them in your landscape. Conditions in a four-season climate will cause tropical plants to freeze, get too little sunlight or get too much water. Tropical plants rarely survive outside a tropical environment. If you have a greenhouse, however, you can keep a tropical plant at home, but they require proper care, including regular watering.

Instructions

- 1
  Feel the soil in each tropical plant to determine when the plant needs to be watered. The top one-third of the plant should be completely dry and the bottom two-thirds of the plant should begin to dry out before watering. Test this by sticking your finger into the pot one-third of the way down to feel the soil.
- 2
  Test the plant once a day if the soil still feels damp on the first day. When you find that the bottom two-thirds of the plant has started to dry out, water the plant until water runs out from the bottom of the planter. This both ensures that the plant gets enough water and washes away excess salt in the plant.
- 3
  Dump the water that ran out the bottom of the plant from the planter tray. Don't allow tropical plants to sit in standing water.

  Water the soil at the top of established tropical plants using a hose or spray bottle. Mist tropical plants that are young and tender. Use the lightest spray on your hose and stand three to five feet from the plants or use a spray bottle to keep from damaging a new plant.
