Review: Worked on one of my weak azaleas - I have some mini azaleas in a relatively new landscaping and this Spring they did not bloom. They looked pretty sad, leaves were not lush and no blooms. I poked in a few of these "spikes." It was not easy to get them in; they are less like spikes and more like large capsules, not pointed on either end, just kind of oval like a really huge "caplet". I managed to poke some in when the soil was soft after a rain. A month later I noticed new leafing and then late in the summer, one azalea bloomed--out of season to be sure, but it seems it was waiting for needed nutrients. (The other still looks kind of weak and did nothing.) So perhaps this Fall I'll add a few more; I only gave one or two to each plant and where the weaker plant is, there are a lot of old roots from a tree that was removed, so that soil has to be pretty poor. Based on this "experiment" I'd say for azaleas, these are very effective and a must-have for any garden with poor soil, as mine has. This package is good for a few large plants and is only needed yearly so a decent value.

## Questions & Answers

**Q: Do you just stick these by the base of the bush? How long do they last?**
A: Yes you will want to stick it near the base of the bush.  They seemed to last about 4-6 weeks on my plants.  And my roses have never done better.

**Q: can it be used for rose of sharon**
A: They are not quite the same type of plant. Jobes makes an all-purpose spike, which is what the rose of sharon is supposed to get. I wouldn't over fertilize either, since it will promote new growth, but not necessarily blooms. Now is a good time, early spring.

**Q: Can this be applied with the initial Spring fertilizer timeline of roses, or should it be used separately (later)?**
A: You can use in spring by itself . . .I would not recommend combining with additional fertilizer.  The stakes are large and depending on the size of the roses, you use more than one for each bush.

**Q: Do these work on knock out roses?**
A: I feed my Knockouts 10 10 10 and they look fantastic. I use the Jobe's spikes on my hybrid roses and climbers. I feel sure the knockouts would also love them.

great tomato fertilizer easy to use

### ⭐⭐⭐⭐ we (my kids, plants and I) like 'em!
*by A***K on May 19, 2025*

Fast delivery. No damage noted to the package or the spikes. They are easy to use. There is a little plastic cap included that goes on the spike before you hammer it into the ground (which you soften ahead of time, btw, by watering your plants). They are easy enough to use that my kids use them. They do what they are supposed to do. My plants seem to respond well to them. I have them on a subscribe and save.
