Seeds of Sunflower

I put sunflower seeds in the garden and many parrots came. What should I do to the hull [remaining of seeds] once they have eaten all the seeds? Can I use them as manure for my fruit trees or flowers? Will it harm them? Also,  will the white ants destroy my plants?

Do not use sunflower seed hulls on plants in your garden. They contain a chemical that stunts plants growth. It is best just to dispose of them.

Try mixing boric acid (Borax) and sugar together into a paste and leave it where the termites/ants will walk through it. You should be able to find Borax at the grocery store in the laundry section. This will poison the pests and they will track it back to the nest and kill the ones there too.

Sunflower Seedings

My sunflower seedlings were doing beautifully until one day, they all sort of laid down. The stalks still look healthy and they are continuing to grow leaves, but I am worried that once I transplant them to my garden, they won’t ‘grow up’. Any suggestions for getting them to stand up, or have I done something wrong and do I need to start over?

It sounds like they are getting "leggy". This happens when they do not get enough light. Make sure they get more light, by either moving them to a brighter window or setting them closer to the light source you are using.

Sunflowers for a Wedding

My daughter is getting married in October (live in Topeka, KS) and wants to have sunflowers for her flowers at the ceremony and reception. Varieties include:

-Girasol -mixed colors and Evening Sun
-Autumn Beauty
-Evening Sun
-Lemon Queen
-Red Sun

When should I plant them, in order to have them blooming for October? Should I stagger them, plant some and then plant some more later?

ANSWERS

It would be very hard to say exactly when to plant them in order to get them to bloom but it typically takes 50-90 days, which is a pretty wide range; but there are so many factors, from temps while growing to the variety that influence that. I would start planting in May or June and then do a new planting once a month for the next 2-3 months. That is really the only way you will be able to cover your bets, so to speak, and make sure you have sunflowers ready for the wedding.

Sunflower Shells

I understand that the shells of sunflowers are harmful to grass. Should they also be removed from a garden? My husband put his bird feeders (with sunflowers in them) in my garden, so do I need to remove the shells?

ANSWERS

I would recommend doing so. The shells can keep plants from growing and will even kill existing plants.

Growing Sunflowers

We have been trying to grow sunflowers and something is eating the shoots. How can we prevent this?

ANSWERS

Without knowing what pest is is, it is hard to give specific advice, but there are several products on the market that generally repel small critters that nibble on shoots. Typically, they are made of predator urine. You can also try hot pepper powder or citrus peels, as these repel most small mammals.

The Tips of My Sunflower Leaves Are Turning Black

Some of the leaves are turning black and starting to curl. The plants look healthy otherwise. I’m watching the amount of water and I would say they are getting enough in the garden, but they are a little dry in the pots. I live in central Fl. (I was told Zone 9b)
Thank you

ANSWERS

I would increase the amount of water they are getting. You want to water them just as the top of the soil gets dry, but not dry all the way through.
