Now Thats Tall :)

Goodness me Sunflower what are you planting them in????? Wonderful!

I do a few things with fertilizer, but the most important thing with giant plants is to find the variety that gets the largest. Most of my work is done on the internet. I spend countless hours searching news articles and websites for information about giant plants. There are gardeners with a much better understanding of soil than me. I know enough to get my plants big. It's finding the best genetics is the challenge.

Wow, what a wonderful hobby out of your garden!
