These jumbo sized sunflowers require a little different soil preparation than the other sunflowers we sell. First step it to take a pitch fork and loosen your soil 12" deep. Next enrich you top soil and till 6" deep until your soil is the consistency of brown sugar. When soil is consistently 70 degrees (for zone 6-7 usually June 1st) plant seed 1/2" deep and a minimum of 12" apart and then top with a light dusting of compost. These are low maintenance and require nothing else other than weekly watering. Don't pinch like branching sunflowers as they are single stem. Unlike other sunflowers we sell you will get the best results if you use a slow release fertilizer, or top with compost monthly, as they use a lot of nutrients as they grow. We don't recommend you start sunflowers early in pots as they send a large tap root when germinating and in pots less than 6" deep will quickly become rootbound and not develop correctly.

The overall vigor of the plant, is very dependent on sufficient soil nutrient levels. To achieve the tallest sunflower possible we suggest you use a nutrient soil test to check your NPK and make sure your PH level is as close to 7 as possible. Additionally these sunflower are very top heavy and if you live in a windy area you might need to stake the sunflowers until the plant stalk becomes a sufficient diameter to support the flower.

Initially the sunflower makes a single large flower (photo 2) and once the plant goes to seed the flower head will expand to a diameter of approximately 12" to 16" (photo3).

Best Blades hands down!
Size: 26" and 16", Style: Pack of 2, Size: 26" and 16", Style: Pack of 2
I purchased the Rain-X WeatherBeater 26” and 16” windshield wiper blade set to replace the factory blades on my vehicle, and installation was straightforward. The included adapters made it easy to get a secure fit, and I had both blades installed in just a few minutes. After several weeks of use, they’ve performed well in both light rain and heavier downpours. The blades make consistent contact across the windshield, leaving very few streaks and improving visibility significantly compared to my old worn-out wipers. They are also relatively quiet, with no noticeable chattering or skipping. One thing I appreciate is the value for the price. While these may not have all the features of premium beam-style blades, they provide reliable performance at a much more affordable cost. Durability remains to be seen over the long term, but so far they have held up well through changing weather conditions. Overall, if you’re looking for a dependable replacement wiper blade set that installs easily and performs as expected, the Rain-X WeatherBeater blades are a solid choice. I’d purchase them again.

Good, reliable wipers.
Size: 24", Style: Pack of 1
I replace my wipers annually, so I don't need to spend a bunch of money on the countless gimmicky wipers that are out there. You used to be able to find Rain-X wipers just about anywhere, but the marketing morons pushing the gimmicky crap have pushed these out of stores. I am please to have found them on Amazon. I am also pleased to find that they are on Subscribe & Save. Most of my vehicles use the same size wipers, so I can buy these throughout the year and replace them when they show up instead of trying to remember when their year is up. I have always liked the performance out of Rain-X wipers. I think they last all year, remaining flexible the whole time and stay silent. That flexibility make them very effective at wiping the windshield. The cost for the wipers was great when they were around $6, but the greedy corporations keep raising prices, so now it much more. I think the value is still there, but the design has not changed. Still good, reliable quality. The size is accurate. The installation is easy. There's instructions if you need them that are easy to follow.

Yes good choice
Size: 22", Style: Pack of 2
Perfect fit and they work great! It's been over a month using these and I would consider purchasing again. The wiper blades on previously looked a little bit more sharp but these outperform them by a long shot.

Rain Wipes
Size: 24" and 19", Style: Pack of 2
Nearly does the trick, where there's a better model option. Wished I had purchase the higher grade model, for this model doesn't wipe as well during moderate and heavy rain. However, for the price I got what I paid for, with my history of this brand, knowing it will have a bit of useable life. It was a fit...Actual replacement. Easy to install. Smooth wipe, for there's no squecking.
