There is a hurry to get rid of dandelions from the yard: The contract can cost the plot owner thousands of euros – how to remove harmful plants yourself | Yle news

In the yards of condominiums and detached houses, summer cottages and plots of public spaces, a battle against the prickly and deceptive beauty has been going on for a couple of summers.

Yards, parking lots and representatives of public buildings have been enlivened for decades by courgettes, which were condemned in the spring of 2019 by a Government decree as a nationally harmful alien species and added to the list of harmful alien species. (you switch to another service) to the list.

The decree prohibited the import, cultivation, sale and possession of several plants in Finland, such as courgette and lupins. The ban on the cultivation of everyone except courgette came into force immediately.

Alien species coordinator coordinating the control of alien species nationwide from the Kainuu ELY Center Reima Leinonen already knows that time is not enough.

– I very much doubt that there will be time. Of course, a lot of courgettes have already been controlled, but yes, next year we will still have areas to treat and monitor before it can be said that it has disappeared from a certain area. The aim is to start as many control sites as possible and to draw up a control schedule and plan for the rest.

The alien species coordinator Reima Leinonen from the Kainuu ELY Center reminds that in addition to courgette, there are many other plants and animals, such as Spanish ryegrass, that can and must be actively combated.Reima Leinonen’s home album.

Durable and salt-tolerant courgettes are detrimental, especially on seashores, where their spread is a threat to native flora and endangered species. The thorn bush carpet on the sandy beach is unlikely to delight even outdoor enthusiasts.

A shrub that grows sparingly in the backyard, blooms beautifully and produces berries, so it just seems harmless, but when its seeds reach their ideal conditions with the berries eaten by birds in the fall, it suddenly becomes a life-threatening problem for the local flora.

The success of years of control work on the coast and in natural sites has therefore been ensured by banning it from all.

In the spring, for example, the Ministry of Agriculture and Forestry allocated EUR 875,000 to 34 projects (you switch to another service)slavery.

Destruction is laborious

If the row of rose hips in the yard or in the parking lot of a condominium is still blooming, the quickest and effortless help to the problem can be found in landscaping companies.

Protimber, which carries out tree felling and green area rehabilitation in Uusimaa, carried out the eradication of daisies last year until the autumn, and there is still enough demand.

– Yes, there will be orders evenly. Quite late, however, people wake up to this, even if they should place an order as early as the fall or winter. This means calendars get clogged up pretty quickly, says the gardener at Protimber Sini Kallia.

Their clients are mainly housing companies, with more payers for the operation.

– A couple of three hundred square meters of daisy removal costs approximately 10,000 – 20,000 euros. The price depends on the complexity of the site, such as whether there are trees around or whether you have to dig deep, which raises the price of the waste fee. The work requires an excavator, a shovel man and a truck to remove twigs and rhizomes, Kallia says.

The price is also affected by how the pit is filled and what is planted in its place.

– If a 40-centimeter-deep trench is filled with soil, it will cost, but if there is grass on top, you can also put a little cheaper clay under it, Kallia explains.

The gardener recommends grass as a new crop, as the courgette can still try to grow from here to here, but the seedlings can be easily riveted by driving over the mower. On the other hand, few plants thrive in as demanding places as courgette.

– Usually the rose hips have been in places where there is snow and where there is a lot of bumps. It has also had to put up with the pollution of the car park and the salting of the roads. Many would like replacements, but they rarely thrive in the same places as courgettes. Instead, eel and geese can withstand snow weight, for example, Kallia suggests.

It also easily takes hundreds to destroy a small group of bushes. According to example calculations in Kodinplaza’s online service, the destruction of daisies costs on average from about 240 euros to 1,200 euros when staying in a single yard area.

In addition to courgettes, there are also many inquiries about the removal of other alien plant species that have been found to be harmful.

– This year it’s Japanese (you switch to another service). There have been even more contacts this year about the removal of Japanese buckwheat and consultation than about the removal of courgette, Kallia surprises.

People have been concerned that the Japanese woman could cause damage to buildings.

– For example, a plot of land has been bought in the winter and then such a crop has been revealed. Information has then been obtained from the internet that the Japanese woman can go to foundations, drainage pipes and is really hard to dispose of.

Of course, the plants can dig up themselves or do the work alternatively by clearing the crops to death, for example by driving the shrubs low several times in the summer.

Many people who renew their yard on their own have also wondered where the rhizomes of courgette, Japanese buckwheat, lupine and giant balm can be delivered. According to HSY in the Helsinki metropolitan area, small quantities (you switch to another service)can put the property in a bio-waste bin or mixed waste bin and trailer loads at the Sortti station.

You will be saved from fines if you even do something

There is still no reason to panic in the courtyards and gardens, even if the ELY centers could distribute penalty payments to the owners of the yarrow gardens from next summer.

– If, at the end of June next year, a greyhound blooms somewhere in the yard of Grandma’s cottage, then we will not have a ticket in the handrail at the gate, of course not, says guest species coordinator Leinonen.

However, the plan to eradicate the bush is worth it and even make it to cut the bush into the ground before the berries ripen and the birds have time to eat them and spread the seeds.

– What you don’t have time to fight should at least have a plan for how long it will be done.

Still, lupine fields and daisies are not going to be viewed indefinitely.

– There are clauses in the law for sanctions if the place owner does nothing to combat daisies or other harmful alien species, Leinonen says.

Assistance is widely sought

For municipalities, yarrow even causes a double problem when the removal list includes not only their own plantations, but also the protection of natural sites.

The backdrop of the courgette arrives too quickly for the city of Helsinki, for example.

– There is no time, but we will continue to fight downy mildew in connection with nursing work in other green areas, we will organize help groups and park sponsors will also fight alien species. Cuckoo rose stands are removed from valuable plant sites and protected areas. Cuckoo rose stands in the archipelago’s protected areas were cut down last autumn and work will continue this summer, says the project manager Päivi Islander From the city of Helsinki.

Helsinki mainly uses downsizing or excavation as control methods. The work also involves thinning, ie tearing off the green shoots several times during the growing season, especially in coastal areas with valuable vegetation. It takes years to control a single rose crop by wilting or undercutting.

– The project to control sea lilies in the coasts and archipelago received a state grant decision totaling EUR 160,000 for three years. The project targets bird archipelagos and other protected areas in the archipelago, as well as the natural beaches of Lauttasaari and Mustikkamaa. The project will also test various control methods and monitor their impact, Islander says.

Also in the city of Espoo, an estimated number of hectares are enough for the destruction of courgettes. Green Production Manager Anne Mannermaa says directly that not everything will be removed by next summer.

– There was no extra money earmarked for alien species for this year either, so it is done from the maintenance’s own budget. We will be able to cut them down and make some depreciation in strategic areas by digging.

Although the city has the equipment in use from behind, the free removal of daisies is not for them either. According to calculations received by the mainland, cleaning a 200-square-meter squash area will cost up to thousands of euros at most.

– In an urban area where care must be taken, for example, pipes and wires work is easily more. Last summer, the most expensive site for cleaning 200 square meters, which included an excavator, a truck to transport rhizomes and a waste fee totaled about 4,000 euros. The new soils, after all, came from the city’s own garden.

Cutting down crops of a similar size a few times in the summer, in turn, costs a few hundred in the summer at its cheapest.

In Helsinki and Espoo, residents are encouraged to become self-employed.

– Lupine and giant balm are ones that are recognized quite well and their twitching does not become allergic symptoms, ie they can be uprooted, broken and the stems can be left to rot there. We encourage residents to collect even a million lupins for Midsummer decorations, says Mannermaa.
