The fascinating world of Echinopsis cacti is surprisingly colorful. When they unfold their magnificent flowers in summer, which emit a lovely scent, they are in no way inferior in beauty to the classic summer flowers. It is the exciting combination of spiked dress and flower splendor that sparks the passion for collecting in so many hobby gardeners. Here you can familiarize yourself with the most beautiful species and varieties that the South American cactus family has to offer. Practical care tips also pave the way for beginners to successfully cultivate Echinopsis cacti.
Care tips
People often refer to the Echinopsis as a farmer's cactus. In earlier years, flowering specimens could often be discovered on the window sills of hard-working farmers' wives who didn't have much time for extensive flower care but didn't want to miss out on a little colorful variety. From this it can easily be concluded that Echinopsis cacti are among the frugal specimens among the prickly succulents. The following care tips show what is essentially important.
Location
The closer the site conditions are to the climatic conditions of their South American homeland, the more opulent Echinopsis develop. Ideally, a suitable window seat or, in summer, a place on the balcony is available. Thanks to their green plant bodies, the succulents can tolerate a few hours of sunshine:
- An east or west window is optimal
- Maximum 80-100 centimeters from the window
- From May to September on the sunny balcony
- As protected as possible from the pelting rain
In October, Echinopsis cacti move to their winter quarters. They want to stay there cool for the next 4-6 months, at temperatures between 2 and 12 degrees Celsius. There should be a little light so that there is no need for a laborious adjustment phase in the spring. There is no watering or fertilization during this rest period. From March onwards, the little scratching brushes are woken up from their hibernation and gradually prepared for the new outdoor season.
Substrate
Passionate cactus lovers can discuss the subject of substrate for hours. Over the years, experts have developed their own individual blends. As a rule of thumb, the best cactus soil is well-drained, not compacted and gradually releases the absorbed nutrients and water back into the roots. The following recipes have proven themselves:
- 30-60 percent commercial cactus soil, mixed with mineral components
- Suitable additions are pumice gravel, lava granules, vermiculite, coconut fibers, perlite and sand
TKS1 (peat culture substrate) and pricking soil serve as an alternative to cactus soil, due to their lower proportion of humus compared to potting soil.
Tip:
Cactus substrate with a pH value greater than 7 is absolutely deadly for any Echinopsis. A simple pH value test is therefore recommended before a new mixture is used.
Watering and fertilizing
A key characteristic of cacti is the enormous water storage they are capable of as succulents. Watering is preferably carried out according to this rhythm:
- From March onwards, spray Echinopsis with water from time to time
- Gradually increase the amount of irrigation water until May
- Watering alternately and allowing to dry thoroughly
- From September onwards, reduce the amount of water again until it completely ends in the winter quarters
If you prefer overwintering on the windowsill, water the cactus every now and then so that the root ball does not dry out completely. Basically, you should never water under the blazing midday sun, but rather in the morning or in the evening.
Tip:
Ideally, collected rainwater is available for watering cacti. Hard tap water should first be softened to a pH value of 5.5 to 6.5.
In order for a farmer's cactus to develop its pretty flowers, it needs a balanced supply of nutrients. Special liquid fertilizers are available from specialist retailers that are tailored precisely to your needs. Administer this preparation every one to two weeks from May to September.
