Sunflowers
I cut down my sunflowers yesterday and they were covered in stink bugs. I just flicked them off. Sunflowers are most definitely not pest resistant!
I've planted them 3 times this summer alone, because the little ones keep being eaten. Can anyone tell me how soon after harvesting the seeds can they be replanted?

So, how long do I wait? Does it have to be a whole season? Did you ever find an answer to your house soon sunflower seeds can be replanted? I have the same question. Also, check your seed packet.
Growing Sunflowers
How long does it say your variety will take to blossom? Should you remove the small grown leaves at the base of other leaves as you do with tomato plants;? No, these leaves will turn into full size leaves as the sunflower grows taller. Pinching is generally only done with young sunflowers, and is done to the main tip of the plant.
My 6 year old son was given a sunflower seed from his school to grow back in April, basically at the end of the school year all the kids have a photo taken with their sunflower and who ever grows the tallest sunflower wins a prize. Up to now it has been growing very well. Now all the leave along the stem have turned brown with the exception of some new leaves growing up at the top of the plant.
Unfortunately for my son I have a terrible history of looking after plants, so I am not his best helper. Amazing how I am able to keep my kids alive but not a plant Anyway just wondering whether this plant can be revived or I have I successfully helped to kill off another plant.. As they grow, sunflowers normally drop some of the lower leaves. This can happen with pests and diseases, too. Downy mildew can be a problem in waterlogged soils or during warm humid days with cool, damp nights; it shows up as white fuzzy growth under leaves and mottled pale areas on upper surfaces; eventually the leaves die, starting with older lower leaves.
If you suspect this is the problem, let the soil dry out between waterings and improve air circulation. Water only at the soil surface; avoid getting the leaves wet. Other diseases can cause leaf spots, wilting, etc. Rust, with blisters underneath and black spots on top of leaves can sometimes be a problem. Certain conditions such as lots of rain or heat, may also cause stress. As long as the flower has some healthy leaves up top, though, it may be that, even with certain diseases, the plant will live long enough for the flower to mature.
Be sure that the plant is getting enough light and the proper amount of water; they can stand dry spells fairly well. The most ideal location for planting my sunflowers is a strictly western afternoon sun exposure behind my garage, with some dappled shade in the morning until noon. Anyway I could give my Seedlings enough sun? I have a very important question concerning my 4 Sunspot Sunflowers. I planted them on March 1 about and they have been doing pretty good. They were a great green, they got as much sun as possible, and they were growing at a great rate.
This was all normal. Today, they are extremely yellow and are losing some leaves.
They are a bit wrinkly looking. The soil and water amounts are good, and the drainage system is fine, too. I think they are not getting enough sunlight. Can I do anything possible to give them more sunlight? What can I do to help? Is it possible to help?! If you need them, I will post the pictures of the before sunflowers and the after sunflowers they are still seedlings.
Thanks so much, please help!

HI Blossomleaf; Can you post the before and after pictures? I can tell more when I see the Sunflowers; generally speaking; the type of sunflower you have may not too well in "pots" because sunflowers have long tap roots; do not overwater them; dry them a bit; Anne;. I was thinking you could make the project about " Do Sunflowers grow better in small pots or big pots; try planting some more; see how they go; or maybe a better question: Do Sunflowers grow well in pots; plant a few in the ground to see how they sprout in comparison; thanks; aw;.
Sunflower seed packets should say how many days they take to reach maturity. However, there could be a big window on when the flowers are truly ready to bloom. This can be affected by weather, your soil, pollination, and other factors. Therefore, we would suggest you look at staggering your seeding every couple days and perhaps plant some different varieties that have different maturity times. You can plant sunflower seeds directly into the soil after all danger of spring frost is past.
I planted mammoth sunflower seeds this year and they turned out very nice. There was one in particular that was huge!
Looked gorgeous at full bloom and I wanted to harvest those seeds. But, after I cut it and had it in my garage, it developed a horrible smell. I presume it has been stricken by disease. I am wondering if the seeds will be any good for re-planting next year?

They contributed half of the sunflower seed production globally, which is approximately 23 MMT altogether. From Wikipedia, the free encyclopedia.
This article is about the genus Helianthus. For the common domesticated sunflower, see Helianthus annuus.
Sunflowers are heavy feeders so the soil needs to be nutrient-rich with organic matter or composted aged manure. As they grow, sunflowers normally drop some of the lower leaves. Some have most or all of the large leaves in a rosette at the base of the plant and produce a flowering stem that has leaves that are reduced in size. Some species also have additional shorter scales in the pappus, and one species lacks a pappus entirely. Unfortunately for my son I have a terrible history of looking after plants, so I am not his best helper.
