Pot culture of pelargonium

Pelargonium L'Hér. ex Ait.

Growing pelargonium in a limited volume of substrate, which requires ensuring high root aeration and growth habit control to obtain compact flowering plants.

In the reference 23 varieties crop Geranium, where this is mentioned in the description.

When cultivating pelargonium in pots, a critical factor is the high porosity of the substrate, which ensures aeration of the root system. Professional mixes based on neutralized sphagnum peat are supplemented with coarse aggregates, such as 3–6 mm fraction perlite, pumice, or bark, which prevents moisture stagnation and the development of root rots.

Growth management of pot pelargoniums involves genetic selection of varieties and shoot pinching to promote bushiness. The specifics of individual groups, particularly regal pelargoniums, require the organization of a cool winter dormancy period for the successful initiation of flower bud formation.

The maintenance regime is based on strict control of substrate moisture, allowing it to dry out, which is due to the species' adaptation to its arid native conditions. Pot culture of pelargonium allows for combining active use of the plants in containers during the warm season with their subsequent indoor storage.
