Thank you for your polite reply. I am not over keen on artificial fertiliser myself, the seaweed is organic, but sometimes I find them useful. I have a bottle of tomato feed that I am about half through, and I have only had it three years
One of the joys of this place is its international nature, I have learned a lot about the difference climate makes from the Southern US to Canada, it would be interesting to hear about your garden in a warmer climate still. I imagine the coming cooler season from January would be favourable to a lot of the sort of plants I grow in green houses in Summer, I wonder what grows in your hot season?
Dhaka is huge, there must be every sort of garden there, but you talk of the insects so presumably you have some room. A compost heap is a really useful thing, and in your climate it should work very well. I compost our kitchen waste separately, but I don't suppose that would be a good idea for you, even here it can smell a bit in midsummer. The other problem with kitchen waste I have had is rodents, I have made it so they can't get in now.
My main compost heap is made of staves, about four inches thick, laid two across and then two at right angles, so there is plenty of chance for air. It gets all my prunings , trimmings, weeds, lawn mowings, leaves: all that sort of stick or leaf type of stuff. I mix things in as I put them in, water it, and turn it all regularly, try and keep it good and active so it heats up. That speeds up decomposition, you get compost sooner and if I am successful it kills the weed seeds. I have no idea what weeds there are there, but I bet there is something.
Do hope you stay around and we hear more about how things are going for you.
