Types of pots
Indoor plants are grown in a pot or container of some sort. The compost in the pot provides a medium for supplying moisture and nutrients, and it also supplies anchorage for the plant. As plants grow, they need to be moved into larger pots.
Compost
Ordinary soil is not suitable for house plants because frequent watering eventually cakes it into a hard mass, that admits neither water not air. An open compost is necessary for house plants, and compost for houseplants should be peat-based or contain a fair proportion of peat.
Peat-based composts include Shamrock Seed and Potting Compost, Erin Potting Compost, Bio Potting Compost and Levington Compost, Use lime-free compost Brown Gold, for lime-haters. Mixing these composts with garden soil, unsterilised, helps to deter vine weevils.
