Garden calendar September

Planning, design and construction

The days are getting shorter and it is getting dark earlier at night. Lighting adds atmosphere to a garden and it is also safer if the garden is well lit. Therefore, when building or renovating your garden, don't forget to prepare a lighting plan. Check this video for more information.
Planning to build a veranda in your garden next spring? Make a nice design already in our online drawing tool. Use the Sun and Shadow Simulation to determine the best spot.
Keep an eye on the garden center sale: now you can find the best bargains!
Order spring bulbs now and put them in the garden this fall.
If you notice that there is not so much blooming in your garden this month, go through our PlantEncyclopedia: there are in fact more than enough plants that bloom precisely in September. Order the plants and put them in your garden right away.

Are you going to plant bulbs? Put those of the Winter Acorn and Wood anemone in water overnight before planting.
Fill vacant spots in the border with the plants from your pots or new purchases. The plant will take root quickly because the soil is still warm. Don't forget to water well.
Planning to make a field of wildflowers? You can sow the Marigold, Cornflower and Poppy now for next year's blooms. Of course, you can also sow a wildflower mixture. There are also several mixtures available depending on your soil type.
Spring bloomers such as the Tulip, Crocus, Blue Grape and Daffodil put in the garden as bulbs now.

The Sunflower blooms from July through September

Regularly remove spent flowers from the Dahlia, Rose and annual bloomers. This encourages further flowering.
Want to do new plantings? Container plants and potted plants can be set now. For transplanting trees and shrubs and planting bare root plants, you'll have to wait until fall.
Perennials you want to propagate can now be carefully dug out, torn and replanted.
Garden waste? Throw it on the compost pile.
Clean nest boxes before they go into winter. Birds may just start picking a favorite nest site now.
Start collecting seeds from your spent flowers.

Echinacea or Red Sunflower blooms from July through September

The Monkshood,Liverwort and taller Autumn asters could use some support now: put down a plant support so they don't snap over.
Sunflowers, Dahlias and other late bloomers could also use some support.

Geraniums are true long-bloomers

Move biennial plants to a good spot.
You can give hedges and hedgerows an extra trim now before winter. Pick a cloudy day for this.
Berry bushes such as the Raspberry can also be worked now. Prune away the older branches completely and leave the young ground shoots. If necessary, lead them on a wire.
Climbers that have finished flowering, such as the Hydrangea, can be pruned back. Make sure not to cut everything off rashly, but only the branches with the old inflorescence. On the remaining branches the Hydrangea will flower next year.
Fertilize hedges with compost if necessary.
The Camellia and Rhododendron need a lot of water. If it is dry, give them plenty of water.

The ground has warmed up well lately. This is the perfect time to revamp your lawn because moisture and warmth are the best conditions for germination.
Bare spots in the lawn? Make sure you sow bare spots. First, fill in the potholes with soil.
It is good to fertilize once a month. Pick a time just before a rain.
The grass is not growing as fast now, so you don't have to mow as often.
Is there still a lot of moss formation in the lawn? September is a very good month to scarify the lawn and re-seed if necessary.

Remove emerging weeds in the border, paths and patio immediately. This will prevent it from spreading.
When weeding, be careful not to damage the roots of plants

Care for birds in the garden. Place a large bowl of water and refill it regularly so they can drink and bathe.
Keep a close eye on the pond's water level and refill as needed.
Clean the pump regularly and remove excess algae. Algae growth can also be reduced by releasing water fleas. Scoop excess duckweed from the pond.
Place an oxygen plant if the water remains murky.
Span a fine-mesh net over the pond. This will prevent the leaves from falling into the water.

The apples and pears are ripe now, so pick away!
The berry bushes have given their fruit. After the harvest, you can prune them. Haven't pruned them yet? This can be done now. Red currant bushes, for example, can be thinned out. Remove some of the old branches and leave the younger ones.
You can now harvest all kinds of things in the vegetable garden, such as beans, zucchini, pepper and tomatoes.
In addition to harvesting, there is plenty to sow for a later harvest, such as radishes and lettuce.

Most pears are ripe in September

Set up a bird drinker where animals can drink and the birds can take a bath. Refill the bathtub regularly.
No insect hotel in your garden yet? Place one immediately, preferably with the opening facing south and well sheltered. If possible, put or hang the insect hotel at least one meter above the ground.

From March to September, the female urchin needs a safe haven to raise its young
