Tub plants: When may one exhibit which species?
Contents
Every year the same question: When may potted plants leave their winter quarters and move outside? We'll explain.
when the first rays of sunshine in spring make early trees and bulb flowers blossom, the busy gardener is already scraping his hooves impatiently.
At what point can and should the potted plants wintered in the house or conservatory be removed to the terrace? The answer to this question depends largely on local conditions and the regional climate.
The milder and more protected, the earlier the winter guests are allowed outside.
While robust Mediterranean potted plants may be taken out of their winter quarters early in regions with a mild climate, sensitive plants prefer to remain behind glass for a little longer.
In the Alpine region and on the coast, on the other hand, it is better to wait a little longer before clearing out.
The type of plant also plays a role in determining when clearing can be carried out.
Remove robust plants in April
Tub plants that do not mind slightly cooler temperatures, such as true laurel, plumbago, oleander, fig, camellia, aukube, palms and olive, are allowed on the protected terrace as early as April,
as they like it much better there than in winter storage due to the greater light yield.
Especially in mild locations such as the wine-growing area, early removal of these insensitive species is usually not a problem.
Sensitive children stay in the house until mid-May
Sensitive exotic potted plants such as beautiful mallow (Abutilon hybrids), Mandevilla (Dipladenia), fireweed, hibiscus, lemon and orange trees, gentian bushes, angel trumpet and bougainvillea, on the other hand, may only be released into the open air after the ice saints' day, i.e. from 15 May,
because late frosts, which can cause severe damage to the plants, can be expected until then.
In order not to jeopardise the blooming of these beautiful plants, which are sensitive to the cold, it's better to leave them indoors for a little longer,
until the outside temperature reliably no longer falls below five degrees.
Tip: Smaller pots can also be put out during the waiting period to get a taste of fresh air on nice days and brought back in on bad ones.
Getting potted plants used to the sun
When you take your potted plants out of their winter quarters, you should be careful not to place the plants directly in the sun.
After the long months with indirect or even artificial lighting there is a risk of sunburn and dehydration.
For this reason, it is best to choose a day with cloudy skies and place the pots in a shady place on the terrace or in the house, protected from draughts.
This will allow the plants to slowly get used to the increased radiation and the changed temperatures.
Caution: April is known for its rapid changes in weather.
If snow or night frost is announced, the plants must be covered in time or brought back into the house!
Tips for clearing out potted plants
If you are planning to move your tubs into the garden soon, you should not water the plants a few days beforehand,
as they are much easier to transport with a dried soil ball.
The branches or leaves of some species (e.g. bougainvillea, citrus or palm trees) are covered with spines.
You can protect yourself from cuts during transport by completely wrapping the plant in sacking cloth.
A cord holds the fabric in place without damaging the branches.
Now is also a good time to repot potted plants in fresh soil.
Pruning stimulates new shoots and makes the plant easier to transport.
Plastic pots or plant rollers make it easier to move the plant back and forth.
Clearing out the potted plants from the conservatory and greenhouse creates new space for cuttings, which are cut and grown in spring and summer.
