Click on links below to jump to that question.
It has been very hot here, 100 degrees lately, and all my marigolds are dying. They are all brown and shrivelled up, yet they still have yellow flower tops. I water every day when it is very hot. Why are they drying up and dying?
Even with watering everyday, they are still not getting enough water. In heat like that, you will want to water twice a day and water the pot for several minutes to make sure it is thoroughly soaked.
What could be eating my annuals when I don’t see any bugs/worms/etc? Something is chewing up my annuals in my front flower bed. Marigolds have the leaves chewed up. Allysum have yet to bloom and are quite stunted. I can’t see any bugs around. There are tiny white dots here and there and eventually there’s a hole in the leaf. There are a few tiny ants crawling around.
Please check this url for more detailed information for what appears to be insect pests (you cannot always see them with the naked eye, btw) But they can be controlled.
I planted marigolds (large yellow ones) and they were doing great, but now the blooms are turning brown and dying. The plants are fine, it’s just the blooms. We have 90 degree temps and heavy rain showers. Would this be the reason? I also sprayed with Sevin due to beetles.
Pinch off or cut off all spent flowers. This is called deadheading. You are removing the finished product (seeds) and the plants think they have completed their growth cycle. If deadheaded, they will produce new flowers.I don't use chemicals so can't help you re Sevin dust. A person kills all the beneficial bugs that often take care of the bad guys and my personal feeling is that chemical use can just cause a new set of problems to the garden and our environment. Marigolds are seldom bothered by any insects.
My mother has moved into retirement bungalows and has a border with an ant’s nest in it, which we didn’t discover until planting marigolds. The marigolds have now been eaten, wanting to know if the ants were the reason, and if so, what can we plant in the border that the ants will leave alone?
You don't mention where you live or current weather conditions. If you do not disturb the roots, they will probably do okay. When I transplant in less than ideal situations, I dig a big hole, then dig the plant with a big shovel and take as much soil as possible. I place the transplant and soil in previously made hole and fill the old hole with the soil from the new transplant spot. Water well.
There are aphids on the pepper plants in the greenhouse and I’ve tried garlic to no avail. I seem to remember that marigolds and aphids don’t get along.
Any of the African or French scented Marigolds act as an insect repellent. I use marigolds all over my garden for that reason. But you do need to make sure you have picked a variety that has scent! Some of the newer hybrids are scentless, pretty but not particular practical for that use.
