Materials and Equipments- Flower pots, crocks (broken pieces of pots), potting mixture, khurpi
and watering can (with fine nozzle).
Purpose- Burnt porous clay or cement or plastic pots are commonly used for various purposes in
horticulture. The pots are used in propagation or plants, cultivation of ornamental plants and
flowering annuals. Growing of plants in pots in referred as pot-culture. In pot-culture, operations
such as potting, shifting and filling of pots are very important. Potting refers to planting of plants in
pots containing soil mixture, while shifting means removal of plants from pots and planting them
again in the same or different pot. Plants growing for more than one year in the same pot need
shifting. The time for potting and shifting of plants is monsoon season (July to Sept.) and during
spring (Feb-March).
A. Filling of Pots
Select well-baked and sound flower clay pots of the proper size (the size will depend on age of the
plant and purpose for which the pots are filled). Wash the pot, both inside and outside, with clean
water. Place a large crock on the drainage hole (Plate 1-1). Now put several smaller crocks to a depth
of 5 to 10 cm. dependent upon the size of the pot. Put 1.2 to 2.5 cm layer of coarse sand or coconut
fiber. This necessary to check the washing away of the fine soil particles. Fill the pot with soil
mixture or compost. When half full, press the mixture firmly. Continue filling up to the rim of the
pot. Press the potting mixture again, and finally fill and press mixture to a point where a room of 2 to
3 cm. is left for holding water.
B. Potting
The pots filed as described above can be used for sowing seeds, potting of plants or planting cuttings.
For potting of plants scoop out a hole in the centre of the field pot. Keep the plant in the centre of the
hole with roots well distributed in all directions. Throw potting mixture all round the pant and press it
firmly and uniformly. Care should be taken that planting is not done too deep (Plate 1-4). Irrigate the
plant with watering can fitted with a fine rose. Place the potted plant in a cool shady place for
establishment.
C. Shifting of Plants/Repotting
Each potted plant needs shifting every year to avoid root bound condition. This operation should be
done during the rainy season, In order to remove plant from the pot. It is held with right hand second
and third finger and the thumb along the side of the pot. The pot is then turned down as shown in
plate 2; and then taped gently on the edge of bench or on a pot to loosen the ball of earth. The ball of
earth is then taken cut from the pot carefully, before putting the plant in a new pot the lower fine
roots and some soil is removed. The various steps involved are illustrated in Plate-2. If necessary me
pots be irrigated lightly three to four hours before shifting.
