Because bone meal is made from mostly beef bones, some people wonder if it is possible to get Bovine spongiform encephalopathy, or BSE (also known as Mad Cow Disease), from handling bone meal. First, the animals that are used for making bone meal for plants are tested for the disease and cannot be used for any purpose if the animal is found to be infected. Second, the plants can’t absorb the molecules that cause BSE and, if a person is truly worried, then he or she need only to wear a mask when using the product in the garden, or purchase non-bovine bone meal products. At any rate, the chances of getting mad cow disease from this garden fertilizer are slim to none.
Bone meal fertilizer is used to increase phosphorus in the garden. Phosphorus is essential for plants in order for them to flower. Bone meal phosphorus is easy for plants to take up. Using bone meal will help your flowering plants, like roses or bulbs, grow bigger and more plentiful flowers. Before adding bone meal for plants to your garden, have your soil tested. The effectiveness of bone meal phosphorus drops significantly if the pH of the soil is above 7. If you find that your soil has a pH higher than 7, correct your soil’s pH first before adding bone meal, otherwise the bone meal will not work. Once the soil has been tested, add bone meal fertilizer at the rate of 10 pounds (4.5 kg.) for every 100 square feet (9 sq.
The bone meal will release phosphorus into the soil for up to four months. Bone meal is also useful for balancing out other high nitrogen, organic soil amendments. For example, rotted manure is an excellent source of nitrogen but it tends to lack significant amounts of phosphorus. By mixing bone meal fertilizer in with rotted manure, you have a well balanced organic fertilizer. Adding bone meal to already potted plants in pre-fertelized soil? Any help from an experienced grower on this would be appreciated. My Autos have just started entering the flowering stage and I've read numerous guides that say at this point its a good idea to boost Phosphorus levels to aid with bud growth. I went out and picked up some granular bone meal (Jobes organics 4-10-0) to add to the soil, however I just want to get some feedback before I actually add it. First of all the plants are in store bought soils, one is Miracle Grow Organics and the other is Pro-Mix Premium organic. Is it a good ideal to add additional fert to these types of soil? Also, every account I've read only talks about mixing in bone meal when transplanting or preparing soil before the plants are actually in it. Is it even possible to add granular bone meal, which I understand is water insoluble, to already established pots? If you'd like to see the plants, check out my picture gallery for pics from today.

I started the plants mid may and the soil was brand new, so my guess would be that I'd be fine without it, I was just looking to boost yield if that was an option. 1, 2, 4 and 5 are all in Pro-Mix and 3 is in Miracle Grow. It's not as obvious in the pics, but the ones in PM are all a darker green that's really noticeable in person. Yea the only real issue I've had recently is about 10 days ago I woke up to tons of holes on the leaves of plants 2 and 3, which you can see if you look closely at the pictures. It drove me insane, as everyday I woke up and found more holes and destroyed leaves but couldnt find any insects. After a ton of research I determined it was Oriental/Japanese beetles. Theyre a real bitch because there isn't many options available to repel them, only to kill them if you see them. I bought a beetle trap and set it up on the other side of my yard and have since caught probably 100s and it seems to have almost totally stopped the destruction, which at one point I thought for sure was going to totally kill my plants. I have trimmed the worst leaves and now am just hoping the remaining damage doesnt have too great an effect on the outcome.
Do you think transplanting the smaller ones into bigger pots is worth it at this point? Theyre all in the very early stages of flowering and are autos, which people around here often say not to transplant?
I'll do it if you think it will make a material difference to their size.
