To the woman with the tomato plant in her living-room that flowers but doesn't make fruit: Your plant might not be getting pollinated since it is indoors away from insects. I had the same issue, and carefully pollinated the flowers with a small, soft paintbrush. Sounds weird, but I got my tomatoes!
I would like to ask Mr. Lordahl to please reconsider about recommending mothballed. They are one of the most dangerous household chemicals ever made and should be used in anyway by humans. Thank you for your consideration. I support your grow NYC programs.
Why no leafy veges to kids under 6?
Does diatomacious earth harm earthworms?
What are good mulches to use for flower gardens?
My evergreen and dogwood trees were sprayed with hot water by a careless power washer and are browned out where the water made contact. The lower half of the trees now appear dead. Is there anything that can be done to help these plants survive?
I put veggies scraps in a blender with water and pour into a hole in the garden.
Roof gardens and feeding kids with kale is great but how about all the exhaust in the Bronx and elsewhere. Doesn't this affect the food grown in New York City out of doors?
for squirrels I blend fresh red habanero chilies and garlic and let it sit overnight filter the solution add 2 drops of sishsoap and spray the plants. I noticed squirrels are a problem in early spring when they eat green buds / sprouts and maybe there is scarcity of food. in late spring they leave the plants alone. I would start seedlings indoors in the wider under a 27 W compact fluorescent light.
will vouch for the power of that greenmarket compost! we live in a small apartment, and can't use our own compost, but bring it weekly to the market for others to use. a friend uses what he gets from the greenmarket or LES ecology center in his garden in the west village, and it has made a huge difference that so-called grow formulas could never produce.
everyone can compost, and it makes a tremendous difference in what goes in the garbage/makes your kitchen smell. we use the bio bags in a covered container in the kitchen, and when we fill the bag, throw it in the freezer while awaiting our next market run. within a week, we might have three bags of compost materials, but feel really good sharing it with an org that makes it available to those with gardens!
Congratulations on the compost recycling program. I've been dropping off my scraps at the Grand Army Plaza Greenmarket for about a year. It's very easy and The staff there is great. I freeze everything in quart-sized takeout containers, and drop it off about once a week. It also gives me a chance to shop at the Greenmarket once I'm done.
My zucchini plant looks great but I always have a problem with the fruit. The end where the flower forms seems to rot and wilt. I've looked for worms and bugs can't seem to find anything abnormal. Help.
Last year I tried to grow string beans and zucchini in pots on my balcony (15th Fl.). The zucchini leaves got white spots and the few zucchini that grew seemed stunted, and the string beans got some sort of disease and withered. I thought being up that high I wouldn't have pests. What can I do to be more successful this year?
You can buy Diatomaceus Earth / Diatomite at Napa Auto. You may have to order it from the warehouse . They sell it as Oil / Dry. a large bag is about 12 $. It sold for oil spills It is a good soil amendment the particles the size of fine perlite.
For slugs coffee is a poison / deterrent(I had found a scientific paper about this but need to search it.http://www.slugfence.com/slug_info/body_slug_info.html#coffee
caffeine and nicotine are toxic to many pests and plants developed these substances as a defense.
The systemic insecticide Imiclorprid / Merit has a molecule similar to caffeine
how do you deal with weeds which are too hard to pull out without using toxic chemicals (aside from regular concerns about toxic weed killers, I am also concerned about the animals -squirrels, feral cats, etc. - ingesting anything toxic). Thanks
My mother has yellow spots all over all the leaves on her pear tree. I heard it is caused by a parasite that comes from a juniper bush. Is the tree ok, is there anything we should do
My neighbor and I have discussed the ivy growing around the tree in the street box. I say that the ivy around the base of the tree is not good for the tree. And what about the ivy going up the tree.
I am a novice gardener, and have some insect that is attacking my sweet potato vine, hostas, and morning glory. I don't see any slime anywhere that would indicate slugs. They are making big holes in the middle of all the leaves.
I have a container herb garden on a second floor covered porch. Everything is doing very well, but how do I get rid of white fly? One another topic, in the yard one side of the front steps everything grows mightily. On the other side, everything struggles. Basically same light and water. How best to build up soil in such an instance?
Please ask about how to keep squirrels out of window boxes. They destroyed half my seedlings this spring. I used netting until the seedlings put out a set of true leaves, but if I leave the netting on longer than that the plants get tangled up in it. Now, they are still digging in the boxes and ripping up the plants. (These are ornamentals, not edibles.)Thanks!
I have not had success growing things from seed in my garden. As soon as a seedling appears, something, possibly a squirrel, eats it. For example, I was pleased to see a scarlet runner bean I had planted finally produce one leaf. Next day: the seedling was gone from its pot. Is this normal??? Do I have to cover everything from wildlife and pests? I don't know how farmers do it!
With all the rain, would he say the weather has been ripe for wild mushrooms?
The tomato plant in the big planter in my living room window grew like Jack's beanstalk and seems to be doing beautifully, BUT every time it makes flowers, they sadly drop off, one-by-one, instead of turning into tomatoes. Please advise? Many THANKS!
I have a problem with my White Birch tree. It looks like it is dying suddenly: it has turned brown. I noticed some very small black bugs on the bark. My local plant store said he has been seeing problems on his birch trees.
I am growing raspberry canes in a large container. The plants were thriving, but just this morning I noticed a large number of leaves destroyed by small, white worms. Any idea what these pests are or how to control them? Thanks!
Please discuss when and how to prune flowers before and after they bloom. Thanks.
Help! Whiteflies are devouring the tomato plants on my deck.
Tonight, I'm planting cherry tomatoes in a large pot in my balcony garden. Any specific tips?
