Soil test came back as 7.5% ph or higher. St Augustine is not growing well and not green whatsoever. Can this be applied after a 15-5-10 application (at same time)?

Answer: 
Very likely your 15-5-10 product has some sulfur in it. You can double check it by looking on the back label where it would probably be listed as SO4 in the ingredients listing. It is frequently between 2% and 4%. If you find that to be the case, I would suggest you wait about 4 weeks after the fertilizer. You would not want to apply too much at one time because that could lower the ph too much. Most Read More

I was told to be careful with fertilizing plants for the first year they are planted but this product did not seem to be fertilizer, can I use it to amend the soil when I plant the shrub or I should wait and mix this in a soil later on, I intend to use it planting Hibiscus this coming spring and also possibly mix it in a soil where I planted Rhododendron. Our soil is a clay but I already amended it with garden and top soil, compost and leaves and sand.

Answer: 
Have you tested the ph of the soil? Your hibiscus prefers a ph fairly close to neutral or slightly acidic, meaning a ph of between 6.5 and 7.0. If you do not have very alkaline soil, say 8.0-9.0, it would be a good idea to test before using the sulphur on it. For the best health of the hibiscus, make sure the soil is well drained (you mentioned the soil was clay). Hibiscus like to be well drained. Read More

However, your friend the Rhododendron loves acid soil and by that I mean 4.5 ph. He will be very happy to have sulphur to amend his living conditions if he is not living in a pine forest. The lower the ph, the easier it is for him to get the nutrients he needs from the soil.
When using sulphur, it is almost always best to test the soil first. You can really hurt your friends in the garden if you overuse it. Also, if you want to use it at planting, follow the package directions for doing so.

Answer: 
You can water it in or mix it in soil before or after planting. Not critical for when. You should check your soil's pH before doing the adding of. The container should give a good estimate how much it takes to lower your pH for set amount of soil. If not, just sprinkle 1-2 TBS per cubic ft.

Hi Lara.
Thank you for your question.
Espoma is a great organic fertilizer and it can be mixed into the soil before planting. Since this is a fertilizer, you will need to follow the recommend application rates on the package.
Before adding this pH lowering fertilizer, it would be a good idea to check the pH of your soil since you have already added your soil amendments.
If your pH is neutral, it may Read More
Hi Lara.

If your pH is neutral, it may be better to add a general fertilizer such as Espoma All Purpose Organic Fertilizer or Espoma Rose Tone for Roses and other Flowering plants that promotes flowering.
Please let us know if we can be of further assistance.

Answer: 
When it comes to weight, you can't use the formula for liquids in general, such as 2 cups = 16 oz. That's liquid weight and not dry weight. It all depends on the density of the granules or powder or whatever else it may be that will dictate what the weight comes out to per cup. Your best bet is to pour out the bag into cup measurements, using a 2 or 4 cup utensil, and see how many cups it does in total. Read More

Your best bet is to pour out the bag into cup measurements, using a 2 or 4 cup utensil, and see how many cups it does in total. Or if you have used some already, try to determine say, a half a bag and use the 3lbs left as how many cups it makes. Then you'll know how much each cup weighs thereafter. Read Less

Answer: 
Yes you can. Although it will be the most helpful for your gardenia plants. The myrtles aren't picky about the pH as much. It can be alkaline, neutral or acidic for myrtles. With the exception of the "Pink Floyd" type of myrtle tree. That likes more acidic conditions.

Yes you can. It can be very beneficial for both of those. The crepe myrtle tree isn't really picky on this subject though. Whether it be acidic, neutral, or alkaline, they would do well. There is an exception, if it's the 'Pink Floyd' type, than it likes more acidic conditions. But those trees are harder to find when buying, usually. As far as Gardenias, yes definitely.

Rated 3.9 out of 5 by 33 reviewers.
Rated 5.0 out of 5.0 by very good Product I just used it on 8 blueberry bushes. I hope that it will be OK. The soil looks very good, One third sand, one third peat and one third soil from Home depot. June 28, 2016
Rated 3.0 out of 5.0 by will my shrub bloom directions are very vague for application of product July 12, 2016
Rated 5.0 out of 5.0 by Hydrangeas turned to blue in just a week Surprised at how effective this product worked. Just one application and my hydrangeas were turning from pink to purple to blue. June 28, 2016
Rated 5.0 out of 5.0 by WORKED BEAUTIFULLY I use a service to fertilize my garden. They do an excellent job but not for plants that need acid soil. My wife objected to the fact that our gardenia had very few and very poor flowers. I set out to buy garden sulphur but couldn't figure out what I would do with 20 pounds of it so I settled for soil acidifier with which I was unfamiliar. The results were amazing. It's been about 2 weeks and the sad looking yellow leaves are green and there are blooms and lots of buds. June 8, 2016
Rated 5.0 out of 5.0 by 6 lb. Soil Acidifier 6 lb. Soil Acidifier works well to lower pH of our soil to enhance blooming and color of acid loving plants May 31, 2016
Rated 5.0 out of 5.0 by Got the job done Bought this to make our pink hydrangea flower change to blue. Worked great! May 10, 2016
Rated 1.0 out of 5.0 by Didn't move the needle at all With tested soil alkaline level at 8, I needed to acidify my soil. If the product would have just taken my soil to 7, I could have added another bag to get to my desired 6-6.5. After one week of normal watering after application, we didn't move the needle at all on our PH meters (testing always with 2 meters). May 6, 2016
Rated 4.0 out of 5.0 by Hydrangea Easy to apply. We have to wait for the flowers to see results. April 12, 2016
