Some flower species have specific cultural fertility requirements not met by the more generalized recommendations. For specifics, gardeners are best off to research the needs of individual species for the flower fertilization applications. Here are a few…..
Fertilizer for flowers by species
Here is a rundown of AGGRAND applications for flower fertilization….. many include links for organic production. Sunflowers, roses, hydrangeas, peonies, dahlias, lavender, petunias, pansies. Foxglove, heath, gardenia, bleeding heart and other acid-loving flowers. Also azalea, rhododendron, magnolia, dogwood and other acid-loving flowering bushes and trees.
Sunflowers can grow those roots down to three or four feet below the topsoil. They really do not need fertilizer since they grow so very quickly at up to five to seven feet in 90 days. So if your soil is nutrient-poor, sandy, silty, clay or worse, then try adding some fertilizer in a band down your row. Go low on the nitrogen though, so that means more Liquid Kelp and Liquid Bonemeal. But you can prepare the bed with the AGGRAND 4-3-3 in Spring or Autumn. If your sunflowers have the right nutrients then the flower heads get larger in the end. AGGRAND also produces more oils and proteins in the foods and seeds. So flower fertilization for sunflowers might not be necessary but if you want larger seeds and more oil and proteins from a crop of sunflowers, then fertilize away.
Organic Fertilizer for Sunflowers
Certified organic sunflower products means an NOP-certified fertilizer. We have it and in bulk. ORGANIC SERIES 4-3-3 is certified organic, formulated with OMRI-listed ingredients. Sold in 5-gallon pails, 55-gallon-drums and 275-gallon totes. Use for preparing the soil for the crop, but go low later since this is a 4-3-3 with readily available nitrogen. You will also want the AGGRAND Organic Series Liquid Kelp with Sulfate of Potash, a certified organic concentrated formulation of kelp with an extra helping of sulfur, the fourth macronutrient. Organic Series Liquid Kelp by AGGRAND is a seaweed / kelp concentrate that is certified organic and also can be used by organic growers for sunflower products such as seeds, oils, food and personal care products.
HOME USE IN PERSONAL CARE AND SEEDS: Though this is flower fertilization on a commercial, organic level, many home gardeners are using their sunflower proceeds of seeds, oils and decorative uses of the flower in way that an organic growing system will be protective, so consider using our All Natural 4-3-3 which is the same as the Organic Series though with bloodmeal and not certified.

Fertilizer for roses
For established roses, the balanced fertilizer of 10-10-10, or a high phosphorous fertilizer like 5-10-5 and 10-20-10 that also include macronutrients of sulphur, calcium and magnesium, plus the macronutrients. AGGRAND fertilizers have these nutrients including amino acids, plant growth hormones and micronutrients readily available to your roses. If you add the AGGRAND Liquid Bonemeal 0-12-0 to the Liquid Fertilizer 4-3-3, you have that high middle number for the phosphorous to create strong roots and substantial blooms. Magnesium is an important nutrient to intensify the flower color, increase bloom production and to flush salts and chlorides through the soil. AGGRAND does not have chlorides but some fertilizers once used may have. Magnesium sulfate from Epsom salts can be added by using one-quarter to one-half cup per plant one or two times a year. Roses like their leaves and feet kept dry and one inch of water each week during the growing season. Of course, the soil type and weather dictates watering. the point is, the soaker hose system in rose beds is highly best to prevent disease and keep blooms perfect. This means your AGGRAND liquid fertilizers can be applied through the drip irrigation or to the roots in a banded row, see above for banding. You are using all natural fertilizers with AGGRAND, so applying every month beginning in Spring when leaves open is a good plan. Do not apply fertilizers after mid-summer, meaning 8 weeks before predicted frost, so new soft tissue does not develop that can be winter-damaged. Though the roses can be fertilized after the plants are dormant so the fertilizer is available in Spring when the roses plants begin growing. The AGGRAND Liquid Kelp 0-0-8 for potassium that enacts winter hardiness and the Liquid Bonemeal 0-12-0 with high phosphorous will be a good combination for roses through autumn, winter and Spring. Then begin the Spring application when the rose plant has 4 to six inches of new growth is with AGGRAND 4-3-3 and Liquid Kelp and Liquid Bonemeal. Repeat each month, adjusting as rose needs. Container roses, every four weeks, others can go six weeks. New roses, only use our Liquid Bonemeal in the planting hole then fertilize with 4-3-3 and some Liquid Kelp 0-8-0 when there are five-inches of new growth. The point is, new roses, let the roots get established, no rush for blooms.
Flower fertilization for hydrangea
The hydrangeas really like their acid soil, or sour conditions. A high pH is off-putting to them and to the rhododendron, azalea, magnolia and dogwood. To read more on these, see below for acid-loving flowering bushes and trees where it is all covered.
Fertilizer for peony
The peonies are top-heavy flowers that can live one hundred years. The nutrient imbalances they might go through often results in a reduction in flowering or no flowering and the weak stem syndrome. We have all seen a garden with peonies lamenting on the ground, too weak to hold their heads up and no support wired in, which is always a good idea, no matter how strong the stems.
Worse after rainfall when they do not pop back up like the petunias and the reason for the support. For the weak stems, they need the phosphorous. For lush green leaves to soak up the sunlight, the nitrogen, but not so much that they are all leaves and no blooms and have weak stems, so the AGGRAND 4-3-3 is a good level and very balanced beginning. For rebounding from stress like frost, drought, drenching, disease, pests… they need the potassium which is in the 4-3-3 and in the Liquid Kelp 0-0-8, a good fertilizer to have on hand for stresses so you can lightly mist the plants as needed. For the massive blooms and great roots and stem formation, the phosphorous supplied in AGGRAND Liquid Bonemeal 0-12-0. Also disbudding is done when the buds are visible to create even larger blooms. Disbudding is where the terminal bud on all stem tips is left but the side buds are removed. If the soil pH is way too low, meaning much lower than neutral which is 6.0 then they would respond well to some extra calcium provided by AGGRAND Liquid Lime which raises the pH since that is probably a deficiency in the calcium anyway. If the pH is around 6.0 to 7.0 it is good. A little under 6.0 is slightly too low and the 4-3-3 and Liquid Bonemeal which also includes calcium will detail the needs. Fertilize with the 4-3-3 and Liquid Kelp in early spring with a few inches growth. Fertilize with the Liquid Bonemeal in early spring too and add some in Autumn when the leaves are beginning to fall, the plant will have this for spring and the soil will improve too. Fertilize when they have a little growth and again halfway through the growing spurt before the flowering.
Fertilizer for dahlia
Dahlias want high phosphorous and potassium but a neutral pH of 6.0 to 7.0. Depending on your soil, the AGGRAND Liquid Bonemeal and AGGRAND Liquid Kelp in combination could be all you need. 0-15-15 can be used, no nitrogen. The addition of AGGRAND 4-3-3 adds a low nitrogen that is based with menhaden fish fertilizer along with more phosphorous and potassium for a 4-15-11 balance. Add extra liquid bonemeal or liquid kelp as you wish but remember our liquid kelp is potent potassium, not a synthetic nutrient so you seldom need more than one-fourth what you are using in the 4-3-3 or Liquid Bonemeal. You will want a very high dilution. A spray on the plants is good, leaves and stems, as well as the soil fertilizer application. The shallow rooted dahlia will soak it right up. The nitrogen if used in excess is not all that makes too much plant and not enough flowering though. Dahlias tend to get lengthy no matter what, so for the bushier plants with blooms all over the place, top them above the first three leaves. AGGRAND Liquid 4-3-3 with Liquid Bonemeal and Liquid Kelp in Spring before planting is good prep then fertilize with the extra liquid bonemeal and liquid kelp monthly for those blooms. Finish soil in Autumn after lifting the tubers by adding more Liquid Bonemeal and some 4-3-3 to work in.
Fertilizer for lavender
Seen those massive lavender plants along a stone wall and wonder why yours is short and thin? Fertilizer, fertilizer. They will often say it needs none, but keep reading and you find as many pros saying to fertilize your lavender. Aromatic lavender is a flower and herb that grows right on limestone based soil in the natural habitat, so you are growing a calcium loving flower. That means AGGRAND Liquid Lime is needed for the sweetened soil. Our Liquid Lime adds the extra calcium immediately and continues a slow-release to the plant too, gentle and inexpensive and natural. We will seldom say this on our website, but do not use the granule fertilizers on lavender because it will burn this flower. Lavender loves it all, the AGGRAND 4-3-3 with nitrogen, the Liquid Bonemeal 0-12-0 and Liquid Kelp 0-0-8. Recommendation here is in Spring, apply 4-3-3 with Liquid Lime to the soil. Two weeks later, Liquid Bonemeal to the soil and Liquid Kelp as a foliar spray. Three weeks later a combination of 4-3-3 with Liquid Kelp spray application. Next week, some Liquid Bonemeal to the soil. Talking a few ounces to a gallon, a cup of the mixture per plant, since you don’t want to over fertilize, but the lavender wants to eat and this is all natural. If you are growing for oil, the Liquid Kelp spray applications improves the oils and proteins of plants. Every time you fertilize with AGGRAND the flowers go wheee! and lavender is one that loves more in small doses. Click for the storefront…..

Fertilizer for petunias
These are the annual-like perennials of summer that can be overwintered and do love a lot of phosphorous – in the case of AGGRAND that is the Liquid Bonemeal. So the AGGRAND All Natural 4-3-3 with Liquid Bonemeal right off and again every three weeks but without the bonemeal. Too much phosphorous will make the plants more long-branched, lower phosphorous makes the plants fuller. If you like, try a spray application of highly diluted Liquid Kelp for plant growth hormones and micronutrient benefits too. We alternate these treatments so the high side of liquid phosphorous and 4-3-3 is given to the root in the hanging basket and the flowers award us. Most of the time the petunias are in hanging baskets and cannot be over-watered once they are grown. So the fertilizer can be used every five days. Just click to go shopping.
Fertilizer for pansy
The favorite for me is the blue-faced pansy with the golden eyes. Often called violas. Pansies are going to love the All Natural 4-3-3 and Liquid Kelp. The Liquid Bonemeal is too much phosphorous for pansies to stay compact. The other issues with them is they will grow first in Spring in cool soil and keep growing in the Autumn and even Winter, depending on location. The watering needs to slow down in cool weather or they will literally drown. The fertilization is needed and a good high dilution of 4-3-3 with the Liquid Kelp is base. Three ounces of 4-3-3 with one ounce of AGGRAND Liquid Kelp in a fine mist every three weeks to the plants, avoiding flowers and not spraying in sunlight. Use the Liquid Bonemeal in Spring early and late in Autumn. The gardeners in warm climates, same thing, only adapted to your zone for pansy flower fertilization.
Fertilizer for Lily
Asiatic lilies, calla lilies, the peace lily prefer soil with balanced macronutrients, which is what the AGGRAND 4-3-3 delivers naturally. For the lily flower, use when they emerge from the soil then fertilize one month later. AGGRAND is a quick-release and slow-release fertilizer blend when using the 4-3-3. When you need more phosphorous in the soil or potassium or there has been stress on the lilies, then the Liquid Bonemeal and Liquid Kelp. It is said that fertilizer for lilies is not really necessary unless…. you are dealing with poor soil, raising show lilies, raising lilies for medicinal purposes. You don’t want too much nitrogen or stems could be weak and leaves lush. Our AGGRAND 4-3-3 is a light natural nitrogen that can be well diluted and will not out-balance the liquid bonemeal and liquid kelp. It is also said that the lily will love coffee grounds which makes the soil more acidic, so many people also use these. Though they are not fertilizer, the great deal is these coffee grounds act as a mulch and create a loose organic soil too.
Acid loving, low pH preferences in these garden flowers
Here’s the list for acid loving flowers that like a pH of 5.5 to 6.5…… camellia, astilbe, foxglove, bergenia, goats beard, big blue lily, Tibetan blue poppy, marigold, bugleweed, phlox, Japanese skimmia, narcissus, chive and yes the flowers are lovely, bleeding heart, pink lady slipper, creeping phlox, aster, gardenia, lewisia, roses, wintergreen, lily-of-the-valley, lupine, bog rosemary, gentian, flag iris, heath, heather and fern. The list on this flower fertilization page is taken from our Flower Fertilizer page though they are not the same information. Visit for a lot of information on fertilizing flowers and using AGGRAND natural fertilizers and liquid lime to do so.
There are several flowers on both the acid and alkaline lists. Dahlia, zinnia, coneflower and Shasta daisy do tolerate neutral soil. There are many others too, so check the Farmer’s Almanac or elsewhere for detail. Evening primrose is on all lists, as this little gem tolerates acidic, neutral and alkaline soil pH. Liquid Bonemeal with 4-3-3 and Liquid Kelp. Don’t be misled by numbers — the acid loving flowers prefer truly sour soil in the 5.0 to 6.0 pH range. For some a little higher is okay, pushing neutral even, but always lower than 7.0. Though many instances in my reading I have found the acid flowers listed from 6.0 to 7.0 pH. That is false information, since truly acidic soil is below 6.5 and 6.5 to 7.5 is more neutral. Check each flower for details. We do our best but we are not all conclusive. What flowers want more than acidic or alkaline is to be fed. They will live well in about anything as long as they are getting the nutrients they need for deep root growth and prolific blooms. And that’s why you are growing them, the flowers, those gorgeous blooms.
Acid loving, low pH preferring, flowering bushes and ornamental trees
This is a short list taken from our Flower Fertilizer page for flowering shrubs and ornamental trees…. azalea, hydrangea, holly, mountain ash, mountain laurel, rhododendron, magnolia, winterberry, sweetbush, bayberry, dogwood, blueberry, birch, evergreen and firs. Again, Liquid Bonemeal with 4-3-3 and Liquid Kelp so their soil doesn’t sweeten. No liquid lime which adds calcium and raises the pH easily.
Alkaline loving, higher pH preference in flowers and flowering bushes
If the flower or shrub is not on the acid loving list, then it would prefer a more neutral or even highly alkaline soil. Check each of yours for details. If your flower or shrub wants sweet soil, the AGGRAND Liquid Lime is going to raise your soil pH if it needs raised. If not, then go for the AGGRAND Liquid Bonemeal 0-12-0 for added phosphorous and some calcium. In other words, you can choose the AGGRAND 4-3-3, AGGRAND Liquid kelp 0-0-8, AGGRAND Liquid Bonemeal and perhaps the AGGRAND Liquid Lime, though you don’t need both of the last two.
