Is Bone Meal Good for Hydrangeas?
Yes, bone meal is good for Hydrangeas. It’s an organic fertilizer with high levels of phosphorus and calcium, encouraging growth and producing large, colorful blooms. As a slow-release fertilizer, it doesn’t produce excessive growth, stress the plant, or create root burn. It is also a soil acidifier.
Hydrangeas are the type of blooms that command attention in any garden. When in bloom, they become the center point and overpower the surrounding flowers with their bright hues. With such a beautiful flowering plant, it’s good to know how to enhance its growth and the growth of its flowers.
But, to get there, hydrangeas require a lot of attention and, of course, the appropriate kind of plant food. When applying bone meal to hydrangeas, consider the organic fertilizer a plant food supplement. Use it only in conduction with other basic plant food such as good soil, compost, and nutrient sprays like seaweed or fish emulsion.
It will aid hydrangea growth and hydrangea bloom size but should not be the only fertilizer you use for your flowering plants. Bone meal, as the name implies, is an organic fertilizer made by crushing dry animal bones.
The bones are first heated to destroy any bacteria before being pulverized. There is a lot more to this process, and the science behind it is quite fascinating. The following content sheds more light on the benefits of using bone meal for hydrangeas.
– How Much Bone Meal To Add to Hydrangeas
Apply 1 to 2 pounds of bone meal to hydrangeas (2.25 cups of bone meal = 1 pound). The instructions are printed on the bag or box and can even be used in pots. For best results, combine it with blood meal for hydrangeas, a separate product that can be used to deliver nitrogen to your garden. Nitrogen is what keeps plants green.
– Hydrangeas Can Get Calcium From Bone Meal
Plants like hydrangeas absorb calcium from the soil via their roots, which is then transferred to the rest of the plant via xylem tissue which makes them turn blue. Blue hydrangeas require more acidic soil than pink hydrangeas, so apply fertilizer as required.
Calcium is a crucial plant nutrient. It serves an important role in plant growth and development by providing structural support to plant cellular walls. Calcium is a vital part of cell walls and membranes, which provide structural support to the plant.
When a plant is stressed, calcium functions as a secondary messenger. Calcium is a counter-cation for organic and inorganic anions in the plant vacuole. It is a cytosolic intracellular messenger that regulates plant responses to environmental stresses and diverse developmental cues.
– Phosphorus Is Found in Bone Meal
Phosphorus ‘P’ is a key nutrient for plants in all NPK fertilizers. It is one of the Seventeen necessary nutrients found in plants.It’s this nutrient that causes your hydrangeas to flower more prolifically.
It helps to convert other nutrients into more useful components. Fertilize hydrangeas with it for a good outcome. Phosphorus is essential for root growth and flowering in plants. Plants require more phosphorus than calcium and therefore are more susceptible to lack.
The phosphorus concentration required for maximum productivity is 0.1 to 0.5. In all of this, phosphorus aids in cell division, seed expansion, root development, and the avoidance of stunted plant growth. Excess phosphorus is then stored in plant tissues for future use.
Phosphorus levels in bone meal fertilizer are significant, accounting for around 15% of its nutritional value. The plant’s phosphorus content is easily absorbed using this bone meal fertilizer. Hydrangea color changes with good soil nutrition.
– Bone Meal as a Nitrogen Source
As previously stated, bone meal naturally contains 4% nitrogen. It is also usual for manufacturers to inject extra nitrogen throughout the manufacturing process. Nitrogen is an essential component in plant growth and development.
Unlike other high-nitrogen hydrangea fertilizers, which promote leaf growth at the expense of fruiting, bone meal supplies ample nitrogen to plants. Nitrogen requirements, however, differ based on soil type and plant variety.
Plants for growth, development, and reproduction require nitrogen. A healthy plant has between 3% and 4% nitrogen. Nitrogen is far more important to plants than other nutrients. Zinc is required to produce certain carbohydrates, chlorophyll, and the conversion of starch to sugar.
It is especially important in cold times since it helps plants endure subzero temperatures. Furthermore, zinc aids in synthesizing auxins, which are important for regulating growth and stem elongation.
– Other Amendments Are Balanced Out
Most typical garden additions, such as compost and manure, are high in nitrogen but low in other essential nutrients, such as potassium and phosphorus. Adding bone meal to the ground balances out these inequalities without overloading the soil with any one chemical.
– Functions as a Slow Release Fertilizer
Because bone meal takes a long time to degrade, it gives your plants a regular phosphorus supply throughout the growing hydrangeas season. This means you may use it once and remember about it once you start planning your garden for next year.
– Improves the Health of Flowering Plants
Because plants require phosphorus to flower, gardeners frequently use bone meal for ornamentals such as roses and small bulbs. An infusion around the plants early in the growing season should result in larger, more abundant blooms, and it also aids onion bulb formation.
Some gardeners additionally apply bone meal to the base of their plants just as they begin to bloom to aid with the fruit set.
Cons of Using Bone Meal
There are some disadvantages of using too much bone meal stated below:
- According to a Colorado State University fact sheet, it will not benefit all soil types because its phosphorus primarily favors plants that grow at pH levels lower than 7.0. This means you may need to start doing a soil test before utilizing bone meal.
- Similarly, utilizing bone meal in the garden as a hydrangea fertilizer raises certain safety concerns for children and pets who may consume it. According to the ASPCA, one of the top ten situations reported to Pet Poison Control involves pets becoming ill from ingesting garden items.
- Dogs are often drawn to the animal aroma of bone meal, but consuming too much can result in a cement-like lump in their tummies, obstructing digestion. The easiest method to keep everyone safe is to properly integrate the bone meal into the soil so that it does not clump and to keep it as far away from children and dogs as possible.
- Another reason to utilize bone meal correctly is that too much rain can cause this phosphorus-rich fertilizer to enter water systems and generate an algal bloom. The good news is that natural bone meal poses less risk because it does not leach like other types of fertilizer, but it is still important to monitor your usage.
- Phosphorus overfertilization can force out other vital plant nutrients, such as iron and zinc. Plants with excess phosphorus (or bone meal) will become yellow and exhibit symptoms of other nutritional shortages. Too much phosphorus can harm plant chlorophyll production, producing yellowing leaves (chlorosis).
Most soil is good at managing the amount of phosphorus released. Therefore, overfertilization is unlikely. However, if your soil is not low in phosphorus, you should not use bone meal fertilizer.
Frequently Asked Questions
– Does Bone Meal Promote Hydrangea Blooms?
Yes, bonemeal promotes hydrangea blooms because it boosts phosphorus in the soil, encourages blooming, and is beneficial during spring. These are essential in establishing robust root systems into the soil for up to four months. A slow, consistent fertilizer supply allows you to create an abundance of large, blooming flowers.
– Do Roses Like Bone Meal?
Yes, roses like bone meal for a nutritional boost. One of the most typical directions for planting roses is to toss a cup of bone meal in the bottom of the hole. This is because bone meal contains phosphate, which roses require.
– How Long Does It Take for Bone Meal To Take Effect?
It takes around four months for bone meal to take effect and degrade into the soil, so wait to reapply within that time frame. Bone meal fertilizer for hydrangeas is a good organic fertilizer for providing key minerals like calcium and phosphorus to your plants.
– Is It Possible To Mix Bone Meal With Water for Hydrangeas?
Yes, it is possible to mix bone meal with water for hydrangeas. When making the mixture combine two tablespoons of bone meal with a gallon of water or liquid fertilizer, mix thoroughly before applying it to the soil or lightly sprinkling it over the foliage of your plants.
– What Are Other Varieties of Bone Meal for Hydrangeas?
Other varieties of bone meal fertilizer for hydrangeas are fish and blood meal, and bones prepared from fish bone and other animals other than cattle bones. These bone meal varieties are suitable for various plants, including hydrangeas, fruit, vegetables, flowers, roses, shrubs, and trees.
Hydrangeas can benefit from an adequate source of bone meal as a hydrangea fertilizer but keep the following in mind for best results.
- Bone meal, while a good source of nutrients, does not contain all the nutrients that hydrangeas need. So use it in a good combination with other fertilizers.
- Overuse can result in more damage than good.
- Check the soil ph levels before you feed hydrangeas.
There you have it; with this information soon, you will have a thriving garden of hydrangeas to be proud of. Good luck!
