Thuja plants are evergreen trees growing upto 15 feet tall. The leaves are scattered like a thread. This robust plant needs minimum care. Regular pruning can be done to give desired shape to this plant. A matured plant can produce its seeds during spring season or starting of summer season.
Watering & Sunlight: It prefers full Sunlight but it can also tolerate shady areas. But, if we keep it indoor; we must keep this outdoor at least for 2 days to ensure its long life healthy growth. Spray of Epsom salt mixed water (on weekly basis) on its leaves also help this plant to maintain its better growth. Too much watering may damage the plant. Always water this, when soil becomes dry. Provision of drainage holes in flower pots is must.
Soil:Use of vermicompost and perlite in its soil improves its growth and overall health. To make the ideal potting mix, 20 % drainage media (river sand/ Leca/ Perlite/ Pumice or rice husk- use any one of them) in potting mix should be available. In rest of the potting mix, we should mix Cocopeat (20 %), vermi – compost (20 %) and garden soil (40 %) in equal ratio. Use of Neem Cake (5-10%), will improve further quality of potting mix. If you have planted this in open ground, requirement of fertilisers will reduce, because roots can grow deep in ground to absorb needful nutrients. But if you are having this plant in pot, you must add some liquid fertilisers or vermi-compost every month for better results.
Ornamental use: The plant is used for ornamental purpose. It is very common to keep some leaves in books, a habit common in school kids all over India. Most of you would have done so in your childhood.
