Jobe's Organics Granular Soil Amendment, Organic Soil Acidifier for Blueberry and Hydrangea Plants, 6 lbs Bag

I use this every fall and spring on my blueberries to acidify the soil and fertilize them, and it seems to be working great. Been doing it for about 3 years now, and getting better crops than I used to.

If you have ai available always double check the math on how much to add. The amount they say to give a 16" pot is correct math but incorrect science and will likely kill your plants. 4 tablespoons not a cup and a half. Anyways, the product is good and I always double check instructions and dont hold mistakes against the companies for bad translations. 👇🤗 Espoma Soil Acidifier uses the same container rule: 1 Tbsp per 4" of pot diameter. Same math: a 16" pot gets 4 Tbsp, not 1½ cups.52b09e Espoma The 1½-cup in-ground rates you see online (1¼ cups for a new blueberry/hydrangea, 2½ cups for an established one) are for plants in the ground, spread out to the drip line — not for mixing into a pot.596e4d assets.unilogcorp So yes: the 16" pot measurement on the bag is high compared with the manufacturer’s own container directions. 1½ cups in a pot is roughly a full landscape plant dose stuffed into a container. Vibe-garden version for pots: 4" pot: about 1 Tbsp (bag’s 1½ Tbsp is close enough) 16" pot: 4 Tbsp (¼ cup), not 1½ cups Blueberries / hydrangeas: you can go a little over that ¼ cup if you want, still stay under ½ cup

It came in a box with a couple pairs of scissors and there was a hole in the fertilizer bag so the fertilizer got all over everything, otherwise fine - still not happy about it.

Product is packaged in an easy to use resealable bag and is performing well.

This has done a great job of brightening up the blue and purple tones of my various hydrangea flowers. It brought my gardenia to life - doubling the size and blooms on it. It greatly increased my blueberry yields and I swear it made them taste sweeter. I've been very pleased and have continued to use this.

If you have plants that need a lot of acid (in my case it's blueberries), you need to occasionally add some of this to the soil. It's easy to open, easy to distribute (just toss out on the ground around your plants), and nature will take care of the rest. Just take note of how much to distribute. My experience says that it's better to put too MUCH than too LITTLE.

I followed the directions and mixed in water in appropriate ratio for my potted blueberries. Not sure how well this works since a lot of the product will not dissolve.

If you have blueberries, this is a must. Never thought I could grow blueberries in san Diego. But this fertilizer is magic and easy to use. I do not have a green thumb, but jobes is easy to use and affordable. My blueberry plants/bushes love me and yield big crops because of jobes .

Good product. Arrived quickly

Needed this to amend my soil for my blueberries and it was very easy to work with!

takes 3-4 months to actually work. so I'm guessing at a rating.

Excellent produit arrivé dans le temps prévu. Je suis très contente de mon achat

used this product to acidify a very high alkaline soil...will test PH next spring. Easy to use product.
