Gardening in the ornamental garden

The sowing and planting season continues unabated in May. Seductive sun rays tempt you to plant the first plants directly outdoors. Ultimately, however, the local weather decides how far you can go with gardening. Be sure to harden the plants pre-cultivated in the cold frame or on the windowsill: zinnias, summer asters and student flowers, for example, should be used to the fresh air for a few hours.

Take potted plants outside and repot

The last sensitive potted plants can now be extracted from their winter quarters. Do not place the plants directly in the spring sun so that they can slowly get used to the UV radiation again. When repotting, make sure that the new planter is about five centimeters more in diameter and about 10 centimeters higher. You should also leave a semolina rim at least two centimeters wide in the jar. Before inserting the plants, root balls that are too large can easily be cut off with a spade from the edge.

Tip: Orientate yourself to the size of the root ball, the new planter should only be slightly larger.

Sowing sunflowers

Bring summer flowers that should bloom as early as possible on the windowsill at the latest. To do this, sow three to five seeds in a pot. Drill a hole for each seed with a pickling stick. Remove the seedlings down to the strongest as soon as they have more than two leaves. In the second half of May you can then put the seedlings outdoors.

Insert tubers

Dahlias, gladiolus and begonias can be put outdoors directly from mid-May. The soil should not be too wet or too dry, but should be permeable, nutritious and humus-rich. After planting potassium, add the fully fertilized fertilizer to the planting site. Make sure that you water regularly when the drought is long.

Plant a perennial garden

With increasing warmth and day length, the young plants in the perennial garden grow quickly and robustly. Depending on the weather, you can still plant different perennials in May. Careful soil preparation is important for plant success. To do this, carefully remove the purchased plants from their pots without destroying the roots and carefully place the bale in the intended planting hole. It should be about two to three times the size of the pots in which you bought the perennials. Then fill up the planting holes with loose garden or compost and press gently.

Thinning out shrubs

So that your shrubs stay flowering and loose, you should thinn out and rejuvenate them in May. Plants that bloom in spring may only be cut back after the first flowering. This applies, for example, to the fragrant jasmine, the almond tree or the honeysuckle.

Maintain lawns or create new ones

May is the ideal time to create a new lawn or flower meadow.

Keep the freshly sown area moist regularly, this is the only way the young blades of grass will sprout evenly. If you want to rejuvenate your old lawn, you should fertilize it and, if necessary, scarify it.

Tip: Do not start too low when mowing for the first time, otherwise you will encourage the spread of mosses.

Create a pond

Late spring is the ideal time to create a garden pond. Choose the location so that the pond is illuminated by the sun for at least four to six hours a day. The minimum water depth must be 80 centimeters at the deepest point. To seal your pond, you should use pond sheeting at least one millimeter thick. The easiest way to determine the size of the film after excavation is with a string. Prefabricated ponds are relatively easy to install. It should only be noted that the upper edge is absolutely horizontal and also at the correct height. After excavation and before laying the film, outstanding roots and stones are removed and then an approximately five centimeter thick protective layer of sand is introduced. Now you can fill the pond with water step by step and then plant it.

Tip: Remember that almost all swamp and aquatic plants spread quite quickly, so do not plant too densely!

Remove algae from the pond

Anyone who has already created a pond can now carry out thorough pond cleaning. If filamentous algae have formed during the winter months, the algae floating on the surface must be fished out with a rake. If you want to do something preventive, buy a filter system or use rock granules that inhibit algae growth.

Tip: When planting your pond, pay attention to nutrient-poor pond soil and a balanced selection of plants. Algae will then spread less easily.

Spring on the terrace and balcony

A new decorative sight every season: plant your flower boxes in a way that suits the different seasons. Bulb plants and early flowering primroses are ideal in spring. Wait until mid-May with the summer planting. At this point the ice saints are over and your plants are no longer at risk of frost.

Take care of container plants

After the long winter break, you have to slowly get your potted plants used to fresh air again. Therefore, first place the plants in a place protected from the wind, for example on a house wall, and make sure that the plants are not exposed to direct sunlight. The warm evening sun is best suited - it protects the sensitive plants from burns. During the day the place should be shady.

Tip: Only pot in high-quality potting soil. This is more structurally stable than simple potting soil and does not sag so quickly

Cut back potted plants

Just before your potted plants start to sprout, it's the best time to get them in shape. First cut out the dry branches to thin out the branches. For older bushes, you can also remove some of the oldest main branches. This will create space for new branches and keep your container plants in bloom. Finally, you should shorten the tips of the shoots so that the crowns are nice and round.

Tip: Water your potted plants preferably with rain water, because it is softer than tap water.


In May you can get your container plants out of the winter quarters again.

Fruit Vegetable

After the ice saints, from mid-May, the frosts in the open are over and the soil temperature has also increased noticeably. Now the season begins for all heat-loving vegetables.

Vegetables in May

In addition to salads, cabbage, kohlrabi, Brussels sprouts and herbs, the open-air beds with chicory, carrots, radishes, radishes, parsley, bush beans, runner beans, pumpkin, cucumber, sweet corn and sweet peas are also sown this month. If you sow directly in the field, you should wait until mid-May and apply the seeds thinly in grooves of two to three centimeters deep. After the first germination, the seeds are separated at a distance of 10 to 12 centimeters.

Those who have preferred to sit on the windowsill can gradually harden the young plants of tomatoes, cucumbers and other fruit vegetables and plant them outdoors from mid-May.

Pull the tomatoes on the trellis

Climbing vegetables don't take up much space. With the help of trellises or fences, the plants automatically grow upwards. Fast growing tree tomatoes should be tied to a trellis. This not only looks nice, but also supports growth. Tie the shoots to the horizontal bars. You can attach up to four tomato shoots per post. The distance between the bars should be 50 centimeters.

Grow your own asparagus

It has been known and loved by us since the 18th century, and the Romans and Chinese appreciated it thousands of years ago. Since asparagus tastes best fresh, you should think about growing it in your own garden. This requires open, loose soil in a protected location and, above all, a lot of patience. After all, asparagus plants want to be tended for three years until the first stems can be pricked. But then the amateur gardener can also harvest these "crowns" for up to twenty years.

Create herb stairs

If you love herbs and have little space in the garden or on the terrace, you can also grow the spicy plants up high. Attach a wooden staircase or a shelf to a wall that faces the south side and "stack" the various herbs tightly upwards.

Tip: Pay attention to well-drained and nutrient-poor soil in herb pots.

Process strawberries

Regularly remove weeds between rows, but stop tilling at the beginning of bloom. So that the harvest of the tasty fruits is even more lavish this year, you can do something about it now: Put some straw between the rows, but only after the main bloom, otherwise it will rot quickly when it rains. This prevents the fruit from becoming dirty and fungal attack from below. After harvesting, you have to remove the straw again. Strawberries should be consumed quickly after harvesting. The fruits taste best when harvested after a sunny day preceded by a few rainy days. Be sure to pick only firm fruit with no soft or green spots. Leave the leaves on the fruit and only remove them after careful washing.

Maintenance of trees and shrubs

Many trees and shrubs are in the middle of bloom in May or are about to do so. The following applies to the latter: Now do some important work so that the flowering and the subsequent harvest are abundant.

Plant berry bushes

At this point, the very last opportunity to plant berry bushes, such as the blackberry, is. Anyone who delays the new planting too far risks that the plants will grow poorly and have to be watered much more frequently when it is dry. If you already have a bramble of several years, you can now shorten and untie the side shoots to two or three eyes. In addition, tear out the weak ground shoots.

Cultivate fruit trees

So that fruit trees become more resistant and more robust against diseases and pests, you should carefully maintain the soil around your fruit trees in May. Fruit trees feed on a fine network of roots that extends just below the surface and up to the edge of the crown. Fertilization with garden compost before budding provides sufficient nutrients. Then mulch the tree slice with grass clippings or a mixture of bark mulch and horn shavings.

Blackberry bushes are placed on trellises or tension wires and planted about three finger widths lower than they are in the pot to promote the formation of new rods.

Mulch berry bushes

Now is also the right time for mulching for berry bushes, because like with fruit trees, their roots grow very flat. The soil of berry fruits should be moist and humus - this is supported by the mulching process. Cover the soil generously with straw, leaves or bark compost within a half meter radius. Good to know: This blanket has a yield-increasing and health-promoting effect.

Cut spring rods on raspberries

The raspberry bushes hibernated in May. Leaves and side buds sprout on the rods of last year, later the raspberries ripen here. Young rods are already floating out of the ground between the old rods. The raspberries will fruit on them next year. The spring branches should be cut off with medium to strongly growing raspberry varieties. The rods that later sprout will bear more fruit next year than the spring rods.

Plant protection in May

The warmer the temperatures, the more active the pests become in your garden. The following applies: the earlier you start pest control, the less trouble you have with it in summer and autumn.

Protect apples from maggots

When it gets warmer again at night, the apple wrapper also becomes active. The little animals lay their eggs on the young apples. The maggots that hatch then burrow into the apple. Insert the wasp at the end of May so that the parasite cannot spread. At this point, you should hang up the beneficial animal, which is on small cardboard frames, every three weeks.

Avoid rose mushrooms

Plant brew is a good alternative for everyone who does not want to use chemical clubs. Fungi and lice on roses can be kept under control with garlic brew. To do this, shred some toes and boil them in a liter of water. Then let it steep for 10 to 15 minutes, sieve and let it stand for 24 hours. Use a syringe to spray the leaves and the bottom of the roses three days apart.

Fight vegetable flies

Close-meshed cultural protection nets offer protection against the larvae of the onion and carrot fly. After sowing or planting, place the nets over the bed. If larvae have already spread to the ground, you can use an insect sprinkler.

Prevent spray stain disease

Sweet and sour cherries in particular are affected by this disease. At the time of the cherry blossom, spores form mainly on fallen leaves that have hibernated up to this point. With the wind they get on the new young leaves and the disease can spread. You can only prevent this with special tonics from the garden center.

Tip: Keep collecting snails on a regular basis. The little animals are still very active in spring.
