Make sure your customers understand that they should wait until the danger of frost has passed before planting pelargoniums outside. They will only need moderate watering throughout early spring and autumn when the temperature is low. In midsummer, they need regular good watering, and the frequency of watering depends on the size of the plant and the pot or balcony box. The smaller the volume of soil per plant, the more often you need to water.
A balanced liquid fertiliser given every 10-14 days in spring will help pelargoniums grow strong roots and leaves. Gardeners should then switch to a potassium-rich liquid feed when flowers are forming, to encourage bountiful and beauteous blooms.
Upright and bushy, the Zonal variety is ideal for bedding displays or containers placed in full sun, offering clusters of single or double flowers in a large variety of colours such as red, salmon, pink or white.
If you want to upsell flowering pelargoniums with planters, focus on the Regal and Angel varieties, both of which flower sooner than the Zonal and work exceptionally well as indoor pot plants or in outdoor containers.
For tempting hanging baskets highlight Ivy leaved pelargoniums, whose fleshy leaves will cascade down the sides of baskets and will flower prolifically for months, looking their beautiful best long after other summer baskets have past their peak.
You can also inform fashion-conscious gardeners, that pelargoniums hit the bullseye with two big 2023 trends: Pantone Colour of the year, Viva Magenta – the staple colour of many pelargonium varieties and Mediterranean outdoor style. The same style will help bring your social media accounts to life, tempting would-be consumers with the bold colours and photogenic appeal of pelargoniums.
