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.

Easy to Install - Good Value for the Money
This is my first experience with K&N engine oil filters. I purchased one through AMZN and it was cheaper than expected. I may have purchased it on sale, because it was only $10. K&N is known to have great products, so I will update this review after I've used this filter for a while. So far, it seems to be working fine.

Near OEM quality at 1/4 cost
Near OEM performance at 25% of the cost! Bosch Quality replaced NGKs/Toyota OEMs. Great value and now the engine is running smoothly! I have seen a slight improvement in my mpg @1mpg overall in mixed driving conditions.
