At the end of the season, Sansewieria accepts well Gently feeding sweet potatoes. This vegetable provides primarily potassium and magnesium, which regulate the water management of the leaves and strengthen the rhizomes, without provoking soft, fast growths before winter rest. In addition, it contains smaller amounts of nitrogen, phosphorus, zinc and manganese, thanks to which it works like a natural complement to the diet of the plant. One, a maximum of two floods in October is enough, after which fertilization should be stopped until the start of spring vegetation.
The method of preparing the conditioner is fast and simple. About 100-120 g of chosen sweet potato should be poured with a liter of boiled, lukewarm water and blend for 2-3 minutes, Until a homogeneous mass is formed. Then the liquid must be strained through a sieve or gauze and diluted with water in a 1: 3 ratio. The solution prepared in this way is used at a dose of 100-150 ml for a medium-sized pot, at intervals of about 14 days.

The alternative is a more delicate version, based only on peeling. Just 30-40 g of fresh sweet potato skins pour a liter of boiling water and Leave covered for 1-2 hours. After cooling, the whole is drained, obtaining an infusion with a low concentration of mineral salts, in which potassium dominates and, in trace amounts, phosphorus and zinc are present. The solution does not require dilution, but the dose should be limited to 80-120 ml once every three weeks. It is important not to mix it in the same period with other fertilizers, and in the case of a substrate enriched with granules with a slow effect The dose is best reduced by half.
In summer, Sansewieria needs water on average every 2-3 weeks, However, in autumn, the rhythm of irrigation must be slowed down. Watering is only made after a completely drying of 3-5 cm of substrate, and the one-time dose should be a maximum of 10-15% of the pot volume. You can also use watering “from below”, i.e. by immersing the pot in a bowl for 20-30 minutes, which protects against water retention in the rosette and rotting of the growth cone. The soil must be permeable, with the addition of perlite or pumice and drainage at the bottom.

In the heating season, the biggest problem is dry air and increased activity. Then it is worth maintaining relative humidity at 40-50%, e.g. by putting next to the pot A tray with expanded clay and water. The plant should not stand right next to the radiator or in drafts that can lower the temperature below 12 ° C. If the day is cloudy and dark, it is worth adding lighting with LED lamp 15-25 in the set 30-40 cm above the leaves.
Autumn is also a time to control the condition of the plant. Leaves should be wiped regularly from dust, which improves photosynthesis and limits pests. Pouring symptoms, such as soft, brown spots at the roots, require dryness. Weapons and shields are removed with a swab with vinegar, and spider mites are fought with a solution of potassium soap. Transferring to a larger pot can be done in autumn, but the division of the rhizom better translate in spring.
