Balcony plants and bright sun - Noteworthy
There are many real sun worshipers among the annual balcony plants. Still, blazing sun can be a challenge for some plants.
Many balcony flowers thrive better in a sunny spot than on a north facing balcony. But blazing midday sun can burn mercilessly and even brings some sun worshipers to its limits. Proper selection and particularly attentive care prevent balcony plants from getting limp.
South balcony - look carefully when buying balcony plants
When selecting balcony plants that are exposed to blazing sun and therefore high heat, honest selection is required. Neither beautiful speeches, nor a "will be alright" turns shadow-loving plants into real sun-worshipers, as are geraniums, for example. Even plants with the symbols for sunny to half-shade combined on their care stickers could suffer on the south balcony.
The rule is quite simple in principle: plants that originally come from very mild to hot climates can withstand heat and drought well , Those whose origins lie in cool to harsh climatic zones do, however, on the hot South balcony hard. Attention also with plants, which look for shelter in their natural environment under woody plants or prefer to thrive in damp areas; They will hardly feel well in dry, warm earth under blazing sun.
Planters for blazing sun - the choice of material
Planters made of plastic are not breathable and therefore do not evaporate water. The soil moisture is retained longer, but in blazing sun can quickly create a heat accumulation. Basically, the darker the shade of the planter, the more it heats up.
Natural materials such as clay, terracotta or wood are open-pored and do not heat up too much. However, moisture is released more quickly over the unglazed walls of the planter, so more often must be poured.
Tinplate is decorative, but heats up strongly. The heat is transferred to the earth and the roots of the balcony flowers can become very warm. Metal vessels are therefore not advisable on a south-facing balcony.
If the water can only be poured irregularly, planting pots with integrated water storage are an option. This device continuously releases moisture so that no water shortage can occur. However, for plants that need regular periods of drought, the constant supply of water can be too much of a good thing.
Watering and Maintaining
Unlike perennial bedding plants and shrubs, balcony plants have no chance to develop their root system highly and for the Optimize water absorption. Regular water supply for balcony flowers is therefore mandatory in summer heat. If the potting soil has sunken and condensed due to the watering, it can take up irrigation water worse. Therefore occasionally loosen up the earth's surface, without loosening the roots.
plants that are prone to fungal diseases should preferably be poured early in the morning. This prevents an hour-long, damp-cool climate of potting soil. The susceptibility to mildew and Co. is thus reduced. In the morning, the substrate is also still cool and the moisture does not evaporate immediately.
In bright midday sun, watering should only take place in an emergency. However, if it can not be avoided, the irrigation water must never be too cold. Otherwise it would shock the root system. Therefore, always provide a filled watering can for warming up on the balcony.
Water droplets look like glass in sunlight and leave ugly spots on the leaves. Water better in several, small casts directly on the potting soil. So the substrate can absorb itself slowly and thus more effectively. Alternatively, smaller planters can also be immersed in a filled water bucket. Do not force the flower pot into the water, but let it sink by itself; In this way the earth sucks slowly and completely.
