Can't believe Mr. Lordahl went into the history of community gardens in NYC without mentioning Mayor Giuliani's inexplicable campaign against them. I hope they've recovered since he left office.

Gerard Lordahl claimed falsely that the City doesn't use chemical herbicides or pesticides in NYC Parks. Just go to the entrance of Riverside Park at 103 Street and you will find a notice that NYC has applied the Monsanto product Roundup (a glycolphosphate) to the lawn, which is constantly in use by children.

I (think I) understand fall is the time to transplant evergreens - but when should they be pruned? I have a house on the south shore of LI, the hedges have grown fantastically over the past 10 years. If I trim them to their original height (aprox 4-5 feet) they will be all brown, no leaves. How far back can I trim them and when? I've heard early spring, but am not sure. And will they grow back...?? Thank you so much!

Would love for anyone interested in aquaponics to come visit our garden at 104 Moore Street in Brooklyn. It's an amazing way to grow food in the city.

Hi - there are trees, perhaps thousands of them, that are dead or dying, in areas that experienced salt-water flooding from Sandy.

I've seen them in Coney Island, Red Hook, along the FDR, and elsewhere.

Are these trees in danger of falling during the next storm with strong winds? Are there city plans to remove them?

My Park Slope brownstone has a small garden plot built beside a stoop, about 2 feet wide, 5 foot long and about 2 feet deep, largely dominated by a large lavender plant and some autumn joy sedum. Currently I have marigolds planted. What seeds or plants should I sow/plant for the fall for a hot, dry spot with poor soil?

This summer I was collecting tasty mulberries from the trees along Riverside Drive in uptown Manhattan. None of my friends wanted to eat them because they said they were sprayed with chemicals and were full of city soot. Do you agree?
