Transplanting simply means moving a rooted plant from one place to another. If you prick out tiny tomato seedlings from a propagating tray into individual pots, you’re transplanting. If you decide to move ta large established rosemary from one position in the garden to another you are transplanting.
Follow these steps:
Fill the containers with potting mix. The depth of the soil depends on seedling size, fill your container nearly to the top for small seedlings but start with about 2.5cm of soil for large ones, since you fill the rest of the pot as you transplant.
Pour warm water onto the soil and let it soak through the soil. Moist potting soil prevents seedling roots from drying out.
Toughen your plants for outdoor growing conditions by gradually hardening off. Two weeks before outdoor transplanting, stop feeding and slow down on watering. About a week before you plan to plant out the seedlings, put them outdoors in a protected area, out of direct sun and wind. Leave them outdoors for a few hours at first, then more, then a morning, until they out all day in a sunnier position and out at night.
If your transplants are in plastic or clay pots, turn the pots upside down and slide out the plants or tap the pot with your trowel to dislodge. Plants in peat type or home made paper pots can be planted with their pots, as the roots will emerge into the soil very quickly.
