Q. Marigolds

My Marigolds are about 12-14 inches tall with no sign of a flower….what is wrong or is this normal?

Marigolds come in all sizes. It sounds like you have one of the taller ones and the plants are putting their energy into growth. Once they have reached mature height the blooming commences. Don't fertilize as high levels of nitrogen favor green leafy growth over flowers. Some compost on top of the soil should be sufficient for marigolds unless your soil is quite poor. If bloom starts to lag in late summer, try some liquid fertilizer for a quick boost. Also, if you are having a heat wave, that will delay blooming. Even if well-watered, severe heat is a plant stressor.

Calendulas are cheerful flowers but they are best thought of as annuals. Where winters are warm, they may come back for a year or two but not longer (short-lived perennial). Most of us rely on seed that falls in autumn ands germinates in spring to provide new plants every year. As frost approaches, leave the dead flowers on the plant so there will be lots of seed. Why yours did not self-sow can also be a weather issue. If winter was colder or wetter than usual, the seed may not have survived. I live in Michigan where seeds may not make it through the winter; so gardeners collect seed in the fall. Keep the seeds in a glass jar in the refrigerator and sprinkle them out in spring after danger of frost has passed. This is the one method that ensures you will have lots of calendula every year.

Q. marigolds

Something is killing the leaves and stems of my marigolds. It leaves the flowers alone. I live in zone 8 ( Oklahoma ) and have never had a problem with growing marigolds.

Slugs eat large holes in mature marigold leaves and will completely devour young plants. You won't commonly see slugs feeding on your marigolds because slugs are nocturnal, but you may see the slime trails they leave behind.
Birds, rabbits and disease could also strip leaves.

Q. Japanese beetles and African marigolds

Are you sure about these marigolds deterring Japanese beetles? I planted them all around my garden. The beetles snuggle in the blossoms and appear to mate there. Hardly the repelling I expected to see. I cannot show a picture since I pulled them all up. Had I seen this site before I did that I would have taken a picture for you.

Using plants to deter any pest is a questionable practice. Some swear by it and others have your experience. The few science studies I've seen do not show consistent evidence that specific plants can be used to deter pests or wildlife. Consider treating your lawn from Japanese beetle grubs. Contact your state extension service for the correct time to treat for grubs. Timing is crucial in grub control.

Q. New marigolds have folded stems, should I cut them off? How do I prevent this? Tons of marigolds are also browning as well)

A bunch of the new marigolds i bought from a nursery (3 days ago) have completely bent stems. The flowers don’t look sick or wilting so it is super weird. Out of 23 total flowers on 12 plants, I have 10 of these Bended ones, 6 browning/dead ones, and 7 completely healthy ones. I have other plants that have folded stems that are browning and dying, so I am assuming the bending stems kills the flowers.

1.Should I cut off these flowers with the folded/bent stems?
2.Should I cut off the flowers that are brown and weird.
3. How best to cut them off to prevent infection?
4. How do i prevent these bent stems in the future. (Most important question)

I would appreciate any advice! I have added photos of bent ste flowers and browning/dying flowers.

The flowers may have been damaged in transport or planting, you can pinch off the broken flowers.

Q. Gray stuff on newly bought marigold petals. Immedietly cut flower off. Thoughts?

I bought a bunch of marigolds from a nursery today and noticed one of them had grayish petals. I cut it off and threw it away immediately. Could this be a sign of a fungus or disease in my other marigolds. I haven’t noticed any other gray spots on flowers yet.
What could it be?
Could this be harmful?
What should I look out for?

Q. Marigold

I bought some cheap seeds and planted some are tall some are short. The tall ones are not blooming. Any ideas?! Thanks!!

You may have several varieties of Marigolds, from the seed packet.

Lack of flowers can be growing conditions, pests, not enough sunlight or too much fertilizer or nitrogen in the soil.
