Sow the lawn, divide perennials or fertilize roses:
In our gardening tips for the ornamental garden in September you will find the most important work at a glance.

| Hedgehogs are happy in the autumn about thrown up brushwood heaps, boxes or little houses. Don't forget the cat fuse! |
as summer slowly comes to an end, it's time to get the garden ready for the golden autumn. From lawn care to the hedgehog quarter - we have summarized the most important gardening tips for the ornamental garden in September.
Set up hedgehog quarters
Hedgehogs start looking for suitable winter quarters in September.
If you want to house these useful animals in your garden,
you should build them suitable winter quarters for hedgehogs by September at the latest.
Lay out dry leaves or straw in a sheltered place under bushes and
place an upside-down fruit box on top of it after you have
removed one of the two narrow side walls.
Stick a few bent willow branches into the ground in front of this opening,
so that you have an approximately 30 centimeter long arcade as access.
Finally, heap the entire construction with dry branches and leaves - and the quarter is finished.
Cut back the cockade flower and co. in early fall
Some herbaceous perennials wear themselves out during
flowering to such an extent that their guest appearance in the garden is only short-lived.
This includes, for example, the cockade flower (Gaillardia).
With this species, a strong pruning in early autumn has proven to be a life-saving measure.
The same applies to the small and large-flowered girl's eye
(Coreopsis lanceolata and grandiflora, respectively),
which, in contrast to the needle-leaved species (Coreopsis verticillata),
are naturally short-lived. Admittedly, it is difficult to shorten the
above-mentioned candidates as early as the end of September close to the ground,
because some of them are still in bloom then. But this way,
the plants are encouraged to put all their strength into
the hibernation organs instead of into the flowers, and they get through the cold season better.
Lawn care in autumn
When temperatures are falling, the lawn should be mowed to a height of five centimeters:
If the grass is longer, it can rot; if it is too short, the roots lack protection against the cold.
Leaves that have already fallen down can be conveniently picked up at the same time.
After all, if it is left lying around too long, it also promotes rotting.
This weakens the lawn and it becomes more susceptible to gray mold and other fungal diseases.
Ventilate small, waterlogged areas with a digging fork,
then the roots get back what they need: oxygen, water and nutrients.
Ornamental apples are edible!
From a purely visual point of view, ornamental apples differ significantly from conventional apples.
But they are not poisonous, as is often mistakenly claimed.
On the contrary: Ornamental apples contain a lot of
fruit acid and therefore taste very bitter when eaten fresh from the tree.
But must or jelly from ornamental apples is a highly aromatic treat for the palate.
So there is nothing to be said against extending
the apple harvest to the small relatives in the ornamental garden.

Garden tip: Fertilizing roses with potassium
It is best to fertilize your roses again from the beginning
to mid-September with a low-chloride potassium fertilizer such as Patentkali.
The potassium promotes lignification of the shoots and is stored in the sap of the plant cells.
There it lowers the freezing point similar to de-icing salt and makes the rose shoots more frost-resistant.
Plant bulbs
 |
| Bulbs and tubers of spring bloomers like tulip, narcissus and crocus must be planted in September |
If you have ordered new bulbs in time, the delivery often arrives in the middle of September.
It is best to plant the fresh bulbs in the soil
immediately - they should be planted about twice as deep as they are tall.
A special gardening tip:
For tulips, lilies and other moisture-sensitive species,
sprinkle some coarse building sand into the planting hole before planting the bulb.
Planting time for quilted candles
With the lily-tail (Eremurus), as steppe-candles are also named,
the persistent rumor holds itself, they absolutely must be set in August.
Often it is very warm then and the spider-like root tubers are not yet available.
According to Bernd Schober, owner of the flower bulb mail order company of the same name,
the perennial plants also develop magnificently in the classic autumn planting from September to November.
A sunny place with nutritious, permeable soil is important.
On heavy soils, fine gravel or coarse sand improve water drainage.
The planting pit is dug out so that the steppe candles lie about 15
centimeters deep in the earth and the fleshy,
brittle roots can be spread out well.
Sowing two-year olds
Biennial flowers such as the foxglove (Digitalis purpurea)
or the yellow poppy (Meconopsis cambrica) sow themselves
in suitable locations in the garden and thus appear in different places in the bed every year.
If you are not satisfied with the propagation rate of your two-year-olds,
you can now help a little:
Collect the seeds at the beginning of September and sow them again immediately in different gaps in the bed.
Before you do this, roughen the soil a little with a rake and
press the seeds lightly into the soil with your foot after sowing.
In dry conditions it is best to water the seeds carefully.
House cleaning in the nesting box
In September, the last brood of titmice, sparrows, Kleiber and wren flew out.
But in the Nistkasten, wild hustle and bustle often prevails nevertheless, since bird-fleas,
mites and ticks also made themselves comfortable here.
But not only therefore one should clean the Nistkasten immediately.
The Nature and Biodiversity Conservation Union of Germany (NABU)
points out that cleaning later in the fall could disturb winter
guests worthy of protection such as queen bumblebees or bats.
Tip: Before you go to work with gloves and broom, please knock.
Sometimes there are "intermediate tenants" such as forest or dormice.
New nesting boxes can also be hung up now,
because birds like to use them as shelter on cold autumn and winter days.
 |
| Before cleaning, check carefully whether the nest box is really unoccupied |
Dahlias: Cut off faded
Cut off the wilted flowers of your dahlias continuously above
the first or second leaf below the inflorescence,
because then the stems will continue to produce new buds until
the first night frost puts an end to the flowering spectacle.
For the vase you should only cut fully blooming flower stems - preferably early in the morning.
Leave as many leaves on the stems as is absolutely necessary for aesthetic reasons,
because too many leaves reduce the durability in the vase.
Cover the pond
Depending on weather conditions,
the first deciduous trees lose their leaves as early as the end of September.
Our gardening tip:
Cover your garden pond with a leaf protection net early
so that the leaves do not fall into the pond and enrich it with digested sludge.
Laying a new lawn
Early September is the ideal time to sow new grass.
The summer drought is usually over and the soil is still warm enough for the grass seeds to germinate quickly.
 |
| High-quality seed mixtures grow densely instead of fast. They are more expensive than for example the mixture "Berlin Tiergarten", but worth their money |
Planting winterlings
The approximately pea-size, knobbly tubers of the winterlings (Eranthis)
do not let assume that they become pretty spring bloomers from them.
In fact, they need pH-neutral or calcareous garden soil and a sunny to semi-shady place.
Here, the tubers come five centimeters deep into the soil.
Tip: To make sure that winterlings take root in a straight,
somewhat dry soil, place the tubers in water overnight before planting.

| From the bulbous brown tubers, small spring bloomers with yolk yellow flowers develop in February |
Share a lady's mantle
You want to share your lady's coat?
Simply prick the ground around the plant with a spade.
Then prick deep under the perennial, lift it out together with a generous root ball,
place it on a free patch of soil nearby and first of all divide it in two halves.
Then cut off further pieces with a spade, a knife or with your hands.
Caution: These should be at least the size of a fist.
The "young plants" can immediately get a place in the bed again.
It is important that the perennials are pressed well and watered thoroughly.
The planting distance should be 30 to 40 cm.
Cut blue rain
In order to preserve the luxuriant flowering pile in blue rain
without the up to eight meter high plant getting out of hand,
a rigorous pruning of the flowering short shoots is necessary.
Cut all side shoots of your blue rainbow plant back to 30 to 50 centimeters
approximately two months after flowering.
If new shoots emerge, break them out before they become woody.
This slows down growth and stimulates the formation of flower buds.
 |
| Blue rain tends to grow if it is not cut regularly |
Replant evergreen woody plants
Evergreen conifers and deciduous shrubs should be replanted in September at the latest.
Now they hardly evaporate any water and form new roots in the still warm soil until winter.
Please note, however, that the plants are still more susceptible to frost damage in the first winter,
so it is better to postpone transplanting sensitive species such as camellias until spring.
Chrysanthemums: Thin out the flower attachments
To ensure that your chrysanthemums bloom particularly profusely in the autumn,
our gardening tip is as follows: Too dense flower heads must be thinned out.
Simply pinch out a few buds with your fingers.
If you leave only one bud per shoot, the flowers will be particularly large and luxuriant.
