Properly cultivating farmer's hydrangea - location, fertilizing and cutting: fertilizing

The farmer's hydrangea combines opulent flower splendor with a disciplined growth. This benefits you as a hobby gardener in the form of an uncomplicated cultivation in the bed and tub. With a clever choice of location, balanced fertilization and planned cutting, the course is set for a breathtaking, summerly flowering time, which is reliably repeated every year. This green guide explains in practice and in detail, when and how you should help your majestic ornamental wood. How to properly care for your garden hydrangea.


The choice of the location is groundbreaking for a successful course of cultivating farm hydrangeas. So that the immigrant ornamental wood feels at home in your garden and on the balcony, similar conditions should prevail locally, as in the habitats. In their East Asian homeland, the flowering shrubs thrive primarily as undergrowth in the woods, shielded from blazing sun, pattering rain and stormy wind through a dense foliage roof. This results in the following claims to the light and temperature conditions:
  • Optimal is a half-shady location
  • Happy with mild sun in the morning or evening hours
  • Well protected from wind and cold draft
In shady locations, the flowers remain behind expectations or, in the worst case, completely disappear. A full sun in the bed and on the south balcony is tolerated by the shrub, as long as a sufficient water supply is guaranteed. Nevertheless, a protection from the blazing summer sun at lunchtime should be taken care of, for example in the form of an awning or parasol.

Soil quality and substrate

One of the supporting pillars of professional care is the quality of the earth. In the best case, the soil on the site should be equal to a fragrant, nutritious forest floor, as wild wild hydrangeas like to choose in their homeland. The following attributes significantly support growth and flowering in the bed and tub:
  • Nutrient-rich, humus soil
  • Fresh to moist and permeable
  • In the bucket sour morocco or rhododendron earth
  • Optionally a mix of loam, peat, lava granules and acid leaf or needle compost


Immanently important is an acidic pH between 4.5 and 6.0. In alkaline, calcareous soil, most hydrangeas take care of themselves. It is therefore worthwhile to check the soil acidity with the aid of a test kit. In any well-stocked hardware store or garden center, the test strips are available and can be used without prior chemical knowledge. Using a color reaction, you can see in which area the pH value is moving. This result is completely sufficient for the care of garden hydrangeas. If you mix the substrate for the container culture itself, the pH should also be subjected to this straightforward review.

to water

Freely translated means the scientific genus name Hydrangea 'Wasserschl├╝rferin'. In this way, botanists at the end of the 18th century referred to the high water requirements of hydrangeas when naming. The farmer's hydrangea is no exception in this respect. Demand-oriented casting - beyond stipulated intervals - thus plays an elementary role in expert care. How to do it right:
  • Dries the earth surface, is poured
  • During dry, warm summer days, if necessary, pervade two times daily pervading
  • Run lime-free water directly onto the root disk
The sunnier the location, the more often there is need for casting. Check each morning by thumb sample how it is with the moisture content of the earth. This check is necessary even after a shower, as the drops of water do not always penetrate the dense foliage. Regardless, your farmer's hydrangea may not be bothered with stagnant moisture. Permanently wet roots sooner or later take on the beauty of the flower. Therefore stop the pouring process in the bed as soon as small puddles form because no more moisture is absorbed. In the bucket, the thirst quenches when the water runs out of the bottom opening.
Tip: Rattling, ice cold, hard water from the garden hose may not like garden hydrangea. On damp leaves diseases and pests easily play. In addition, hard water drives the lime content in the soil in the air, which the ornamental shrubs with Blattchlorose and discarding the flower balls quittieren.



One of the primary requirements for the lavish flowering of flowers is a balanced supply of nutrients and trace elements. If you let go of a farmer's hydrangea, you will soon feel her displeasure. In order to fulfill the dream of colorful, romantic flower balls, the specialist trade offers a wealth of specific fertilizers.In the ecologically oriented ornamental garden you have the option of an organic nutrient supply. The different variants are described in more detail below with tips for the correct dosage:

Mineral-organic solid fertilizer

Conventional solid fertilizer does not meet the requirements of farm hydrangeas with their preference for an acidic pH. The specialist trade therefore offers a large number of special fertilizers, such as the substrate Osmocot rhododendron and hydrangea fertilizer or the Beckmann rhododendron fertilizer for all bog beds. The advantage of these long-term fertilizers is that they are given only in spring and once again in summer. Depending on the manufacturer, between 20 and 120 grams per square meter are incorporated into the soil. The resin-coated Osmocot fertilizer even comes out with a single dose, as it releases the active ingredients successively over a period of 6 months. Then pour in lime-free water.

Mineral-organic liquid fertilizer

In order to provide your farm hydrangeas in the bucket with all important nutrients, special liquid fertilizers facilitate the administration. These agents are simply added to the irrigation water. By contrast, products such as Chrystal azalea and hydrangea fertilizer or Cuxin rhododendron and hydrangea fertilizer as liquid fertilizers do not have the depot effect of fertilizer balls or sticks. In the period from March to September, give once a week - depending on the manufacturer - half to one cap on a liter of irrigation water.

Organic fertilizers

The trend towards the ecological management of ornamental and ornamental garden is expressed by the fact that home gardeners leave mineral and mineral-organic fertilizer left. Consequently, the nutrient supply of farm hydrangeas focuses on the use of purely natural fertilizers. These options are available:
  • Acid foliage compost from oak, birch and alder leaves should be lightly harrowed into the soil every 14 days
  • Apply needle compost from spruce or larch needles and grass clippings from March to September
  • Incorporate horn shavings in the soil in spring and summer with a dosage of one handful per plant
Where no own production of compost is possible, a selection of purely organic fertilizers from specialist retailers is available as an alternative. The Neudorf Acetate Hydrangea Fertilizer or the Compo Natural Fertilizer for Rhododendron with Guano is composed of plant and animal components, supplemented with microorganisms. At a dosage of 40 to 90 grams per square meter per month, these fertilizers cover the nutritional needs of your garden hydrangea.
Tip: To strengthen the winter hardiness of your farm hydrangeas, you will end this year's nutrient intake in September with a potassium-enriched fertilizer. Ornamental shrubs fertilized with patent potassium or natural comfrey are better prepared for the rigors of winter as potassium strengthens cell walls and lowers the freezing point of cell water.

To cut

Farmer Hydrangea - Garden Hydrangea - Hydrangea macrophylla

If your farmer's hydrangea sheds the leaves in the fall, she has already planted the buds for the next year. The withered flower balls of the past summer are now still raised head at the end of the branches. When the parchment-like inflorescences glisten with frost and snow in the winter sun, they set decorative accents in the otherwise empty garden. In addition, the underlying buds and leaf roots are additionally protected. Extensive cutting measures are therefore not in the care of garden hydrangeas not on the program. How to proceed professionally:
  • Do not cut a farmer's hydrangea in the fall
  • In February / March clear the bush by removing all deadwood from the base
  • Prepare the withered flowers by March at the latest
As the Asian flowering shrubs in the Central European climate are not unconditionally hardy, the shoots can freeze back a bit in freezing frost. Where this is the case, cut off the dead wood. Place the scissors a short distance above the first healthy leaf knot or next, undamaged bud.
Tip: The innovative varieties from the Endless Summer line are blooming on both the previous year's and this year's wood. These hybrids tolerate in late winter, a more extensive pruning, without this year's flowering fails.


Only in the course of the first years in the bed garden horticulture build a stable frost hardiness. For at least the first 4 to 5 years the ornamental shrubs are dependent on winter protection. Outside mild vineyards, the following precautions are recommended:
  • In autumn, the root plate cover with foliage, straw and fir fronds
  • Place reed mats around the shoots for protection against cold wind
  • Alternatively cover the leafless branches with jute or breathable garden fleece
A farmer's hydrangea in the tub is also dependent on an annual winter protection even in advanced age. Before the first frost, place the shrub in front of the south wall of the house or in a sheltered niche.To prevent the frost from solidifying the root ball from the ground, place the container on a wooden block or polystyrene mats. The substrate receives a layer of foliage or wood wool. Indispensable is a light and air-permeable hood to protect the frost-sensitive buds from frost damage.


Mother Nature did not have the color blue on her plan when she created hydrangeas. To do a little magical nature painting, with a simple twist, you can turn any pink flowered farm hydrangea into a blue shade of your choice. The secret is based on lowering the pH to 4.0 to 4.5. This is how it works:
  • In the pharmacy acquire alum (potassium aluminum sulfate)
  • With this means supplement the normal fertilizer in a dosage of 20 to 80 grams of alum per shrub
  • The more frequent the addition, the more intense the blue hue
  • Alternatively, administer a special hydrangea blue fertilizer from specialist retailers
This chameleon effect works only with pink flowering hydrangeas. Red or white garden hydrangeas refuse this color change consistently.
Tip: Coloring a farmer's hydrangea from pink to blue succeeds more quickly in the tub than in the bed. In the limited substrate volume, alum is absorbed more rapidly and more concentrated by the roots. By first dissolving the powder in boiling water and allowing to cool, increase the effectiveness.



If the selected location proves to be unsuitable, you can transplant a farmer's hydrangea within the first 5 years of your life. Older specimens are usually so deeply rooted that there is a high probability of failure. A suitable date for the action is in the fall or in the spring. In both cases you will have to give up on the next flowering period due to the high stress level, which means transplanting the ornamental shrubs. This is how the location change of a garden hydrangea succeeds:
  • Use a sharp spade to prick the root ball all around
  • The radius corresponds to at least two thirds of the current growth height
  • Loosen the root ball with the grave fork and lift it out of the ground
At the new location, pick up a pit that exceeds the volume of the root ball by a factor of 1.5. The excavation is mixed with deciduous or needle compost and horn shavings. Alternatively, use pure peat bedding to plant the farmer's hydrangea. Sludge the planting hole with collected rainwater and then water abundantly and regularly.

Beautiful varieties

Caipirinha floods the summer garden from June to September with pale yellow flowers that contrast beautifully with the dark green foliage. Thanks to a strong stem, this strain also has the potential to be a high-stem. To do this, support the trunk with a pole and ate the side shoots to the desired crown height.
With their nostalgic charm, farm hydrangeas enchant your summer garden in partially shaded, sheltered locations.The soil at the site should be rich in nutrients, fresh and moist and have an acidic pH of 4.0 to 6.0, so that the Asian flowering plants show their best side. If the care program also focuses on regular watering and balanced fertilization, the romantic flower balls will not be long in coming. After the summer flower festival, the ornamental shrubs go uncut and with a winter protection in the cold season. Only in late winter cut off deadwood and clean out the withered inflorescences. If your garden hydrangeas are taken care of with this care program, they will keep you loyal for many years.
