The optimal care for geraniums - for a perennial flower splendor
Strictly speaking, the balcony flowers commonly referred to as "geraniums" are not such, but pelargoniums - the "botanist" refers to the storks' beaks, which are also native to our country. Pelargonium also belong to the Cranesbill family, but - since they originate from southern Africa - have very different needs than the cranesbill. How to properly cultivate the popular summer flowers.
Early article Plant geraniums properly - flowering throughout the year Next article Cut geraniums properlyHow often do you have to water geraniums?
Geraniums need a lot of water and should be kept slightly moist as evenly as possible. However, occasional drought does not harm the plants, in contrast to waterlogging. Make sure that the appropriate substrate and the right stratification in the planter for a good drainage. In addition, it is better to water more frequently and less than to rarely give the plants a lot of water at a time.
When and with which one should fertilize geraniums?
The flowering geraniums are heavyweighers and should be supplied with a (liquid) fertilizer for flowering plants once a week. Although commercially available special fertilizers, its application is not necessary. Fertilization takes place from the first sprouts in April / May until around the beginning / middle of September. For self-pulled geraniums, start fertilization within six to eight weeks after germination.
Do you have to cut geraniums? If so, when?
If you do not want to hibernate your geraniums, all you need to do is cut off regularly stunted shoots. In contrast, geraniums that are wintered must be cut back once a year. The plants should be trimmed vigorously before the first frost and then be cleared to winter quarters.
When is the best time to repot a geranium?
Shortly before the first new sprouting, transplant your geraniums into a new planter with fresh substrate. The best way to do this task at the end of February / March.
Which diseases / pests are particularly common in geraniums?
Geraniums are quite susceptible to the so-called geranium or Pelargonienrost. In this fungal disease show yellow-brown spots especially on the undersides of the leaves. Furthermore, gray mold (Botrytis), wilt or mildew is quite common. Yellow leaves often indicate iron deficiency. In terms of pests, mites, aphids and thrips are mainly found on geraniums.
The buds on my geraniums dry up - why is it?
If your geraniums develop buds but do not develop, there are several reasons:
Apparently dehydrating buds are not uncommon, especially in rainy summers.
What to do if the geranium does not want to bloom?
If the geranium does not want to flower, it is often due to the abundant foliage. If the plant has too many leaves, the buds do not get enough light - so you have to illuminate the bushy greenhouse so strong.
Are geraniums hardy?
Geraniums are not hardy with us and should therefore winter frost-free, but cool.
Tips
It is also little known that geraniums do not necessarily need soil for wintering.
