Thanks for your question. It seems as if you are wondering why your various plants are not performing as well as those of your neighbor. There are all sorts of reasons for this. In order to help you further, could you please send me a picture of the soil report that you received last year?
Many thanks.

Thanks for using our forum. I had trouble in opening your soil report. Hence my delay. I have now solved that problem so should get an answer back to you shortly.
Thank you for your soil report.
Your soil texture is coarse which implies that it is rather sandy. The high organic content (17.3%) is partly responsible for the elevated phosphorus level in the soil. For 2024, I would suggest that no compost be added. I believe that the existing compost in your garden should be given time for further decomposition. Sometimes too much organic content is not a good thing. As it turns out and depending upon the nature of the compost, some type of chemical fertilizer is often added to the soil having a high organic content. More specifically, I suspect that some form of nitrogen needs to be added. A nitrogen deficiency might have led to the disappointing gardening results that you observed.
It may be hard to find a 15-0-20 fertilizer as was recommended in the report. Rather I would suggest using a 10-10-10 fertilizer. If you apply 1 pound of this fertilizer to 100 square feet of garden, you will then be adding 0.1 pound of nitrogen, 0.1 pound of phosphate, and 0.1 pound of potassium. I would suggest that you do this now (early May 2024) and then repeat this same application in late June. By following this schedule and with frequent watering, I think that you will see an improvement in your garden.
Good luck. Get back to us with any other questions you might have.
