Plant Care Inside a Glass Greenhouse

A young gardener stands among potted greenery beneath a traditional glass roof. Holding a Valentine watering can, she tends to heart-shaped leaves resting on shelves and plant stands throughout the sunlit greenhouse.

How Greenhouses Help Plants Grow

Greenhouses trap heat from sunlight inside their glass structures, creating a warm environment even when the outside temperature is cold. Heart-shaped leaves are common in several popular houseplant species, such as heartleaf philodendrons and sweet heart hoya.

Realistic Colors of Greenhouse Plants

Questions and answers

Questions About Indoor Gardening

Why do plants in greenhouses need regular watering?
Because glass roofs block rain, all moisture inside a greenhouse must be provided manually. Warm greenhouse air also causes water in plant soil to evaporate faster than outdoors.
What makes plant leaves grow into a heart shape?
Broad leaf shapes allow plants growing under forest canopies to capture as much natural sunlight as possible. The rounded lobes help rainwater drain quickly off the leaf tips.
