“The devotee should more fully establish My Deity by solidly constructing a temple, along with beautiful gardens. These gardens should be set aside to provide flowers for the regular daily worship, special Deity processions and holiday observances.” (Srimad-Bhagavatam 11.27.50)
It is very unfortunate that now days Temples are built and the plant life is destroyed (trees, fruit, and flowers bearing plants).
Even if we have a temple in our home, we must also have a garden with at least some flower bearing plants as minimum. It’s ideal to also have many trees. This is because the Deity (God) likes to reside in a natural environment setting, and not barren desert or cement setting.
Plant life is not just desired by God, we humans also need it for our own good. For oxygen, food for humans and animals, as anti-pollutant, shelter for birds, prevents soil erosion, etc..
