These work great for my rose bushes. They are so easy to use and my roses are thriving. The price is comparable or even lower than I’ve found in most brick and mortar stores, plus delivery is so much better than the hassle of driving to the store to get these!These work great in our easy to use. My roses and flowering bushes never looked betterThis does magic for my roses for sure. Great product. It does what it needs to doThese spikes are easy to sow in soil with a sludge hammer if you will or even poke it through the mulch.Because our chickens rule the roost, all my roses are grown in very large pots. I’ve been using these every thirty days, & my roses are huge- they love it! Easiest to use, no mixing, does a great job!I've used jobes products for several years now and I'm always satisfied with how well they work. However, the one thing I found disappointing about this particular Jobes product is that the spike count was inaccurate between bags. It said there is 54 total (3 bags of 18), however, one of my 18 count had only 6.5 spikes in it. Upon receiving these I would count each bag and if it's inaccurate let Amazon.com know.I've used Jobe's spikes in the past and lately, not been able to find them locally at greenhouses or DIY plant departments. No idea why. These fertilizer spikes take the hassle out of mixing my own plant food and sometimes, the green fingers that result. The spike comes with a plastic cap to use when you tap it into the soil. The only thing I've goofed up is pounding the cap too deep. It's meant to be reused. The results are great and I'm happy to have found a source again!This made my roses grow and bloom well over a 15 inches and more blooms then ever before. I originally paid $10 for 10 spikes which is high, subsequent purchases are slightly better at 80 cents per spike instead of $1. The performance of the Product is A+ but would prefer the pricing was more reasonable per spike. However I will continue to buy because my roses love this stuff!This product was exactly what I expected, and worked as I thought it would.This was the first time i was purchasing Jobes Fertilizer Spike and I do love it. Easy to use, the instructions were clear and i am waiting for my roses to bloom. I noticed a good growth of leaves and the plant looks healthy. i will post pictures once i have some rosesHave always used these on my roses , trees ,etc. Keeps them really healthy.They stink but make the roses really grow like crazy!Have to wait for the Spring to comment but have only experienced excellent results from past use.
