One good material to use on the interior of a house is organic cotton. This material is great for everything from carpets to bedding.

hi struti I would say it's matter of choice. marble or even granite or rough stone will have its own charm and definitely long lasting but only when staircase passage is comfortable huge. if space is compact wooden stairs would be better as its could be playfull with spiral or even basics with moulds and finishes, giving staircase elevation a contemporary look thanks shradha shah beescheese design

There is nothing special about Kerala climatic conditions that require anything special (yes, I have several years experience with kitchen cabinets there). You can use BS 710 or 303 plywood with laminate on them with excellent results. Several interior firms also use HDF/MDF with laminate without much complaints from their clients.

I have a Leonard Messel Magnolia that I planted two years ago in fall. It’s a 7-8 foot tree/shrub. It is mostly in full sun. I got few blooms this past spring. But now I see only vegetative buds. Not a single flower bud. Lots of vegetative buds though. I wonder what’s going on. The tree gets enough sun. I did use osmocote fertilizer in spring. Any theories? Also- if there are no flower buds - does it mean/ the tree is done and will eventually decline and die? Is there some cyclicality in magnolia blooms- a good bloom year followed by poor blooms?
