Tuber. The tubers are round, hard and potato-like, with a brown skin and white interior. [4] [5] In December, the plant is dormant, the leaves and stalks dry up and die down to the ground until March when new leaves grow back. [9]: 387
The fifth phase is the maturation of the tubers: the leaves and stems senesce and the tuber skins harden. [61] [62] New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers ...
The tubers are planted in the spring when harvest can occur the following autumn. [4] Coleus esculentus can be harvested 180–200 days after it has been planted. [4] The ideal soil to grow this tuber is a pH of 6.5-7, with an annual rainfall of 700–1100 mm. [4] The ideal photoperiod for the tubers is between 12.5 and 13 hours. [6]
They’re perennial in warm climates, but you’ll need to dig up the bulbs in the fall in zones 8 and colder to save for next year. They grow in sun or shade but need afternoon shade in hot climates.
However, their tuberous nature enables them to survive periods of dormancy, and this characteristic means that gardeners in temperate climates with frosts can grow dahlias successfully, provided the tubers are lifted from the ground and stored in cool yet frost-free conditions during the winter. Planting the tubers quite deep (10–15 cm or 4 ...
