I have a school garden and have planted broccoli in a wine barrel (30 gal). Something is eating the plant, and I don't know what it is. Could it be worms from the white moth?
Yes, most likely it is cabbage moth caterpillar. This article will help: https://www.gardeningknowhow.com/edible/vegetables/broccoli/worms-in-broccoli-caterpillars-in-the-broccoli-head.htm
I sprayed my broccoli with an insecticide. How do I clean it before cooking it?
Most insecticides have a time period that they break down in. Simply waiting that time period will cause it to go away. The time period varies depending on the type you used. You can also soak the vegetables in water for a few hours and discard the water.
In the future, you may want to consider using a human consumable insecticide. We recommend neem oil. It will kill bad bugs but has no adverse effects on people and pets. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
My brassica plants are suffering from attacks of whiteflies. I have tried several insecticides already but the pest seems to be uncontrollable. Please suggest any insecticide available in the market today.
I like neem oil for pests like whitefly. It is safe for people, pets and beneficial bugs but very effective on pests that attack plants. I have even seen it work on vine borers and these are near impossible to kill with pesticide. Here is more information:
I am venturing forth into an actual garden this year- just did two tomatoes in pots and potted herbs last year. Upside down looks good, as I have limited room and drainage is poor. Can broccoli grow upside down? I will actually plant carrots and potatoes in the ground, but was curious about the others.
Broccoli will not do well upside down, but that being said, one of the nice things about using the upside down method is that you can make use of both ends of the bucket. The broccoli can certainly be planted in the soil on the top of the bucket.
Is it possible to obtain information about what vegetables could grow in shade or partial shade? I live outside Gainesville, Florida. Years ago I was living in Tennessee and planted broccoli in partial shade (slightly under a tree) in May and it started producing in July during the heat of summer. The broccoli did not bolt and since I had planted twenty plants (thinking that some of the plants would not survive), I supplied friends and half of the county with lots of free broccoli. What types of veggies would produce in shade/partial shade during the hot, wet months of summer here in Florida?
Any plant that is considered a cool weather vegetable will do ok in the shade during hot weather. Cole crops, like broccoli, cabbage and greens, are some, as well as lettuce and peas.
I recently bought some broccoli and was getting ready to eat it and found a white-looking worm on it. My friend said you have to soak the broccoli first because of this, and that all broccoli has these worms. Is this true? If so, what do you do about it because I do eat broccoli cooked and uncooked.
No, not all broccoli has these worms. If you are buying commercially grown broccoli, you should not find any worms because they use pesticides to stop them. Most organically grown or home grown broccoli will not have caterpillars or worms, but some will slip through. If you are eating organic or home grown broccoli, it does not hurt to soak the heads, but you will find 99 out of 100 times they have no pests.
Do I pull the whole plant or just cut off the head?
Just cut out the head. You may actually get side shoots growing afterwards that can also be harvested.
