Watering should be regular but moderate. The potting mix should be slightly moist but never wet. Too much water suffocates the roots and inhibits flower production. Effective drainage at the bottom of the pot is therefore essential to prevent waterlogging.
The right soil makes all the difference.
High-quality potting soil makes all the difference. Pelargoniums thrive in a rich, light, well-drained substrate. A special potting mix for flowering plants or one specifically formulated for geraniums will provide the nutrients needed for long-lasting blooms.
Remember to repot your plants when the roots become too crowded. A crowded geranium will spend its energy surviving instead of producing flowers.
The iodine trick, use sparingly
Among the tips given by some nurseries, iodine is sometimes mentioned as a little boost. This trace element, which is found naturally in the soil, can help the plant absorb nutrients better.
The rule is simple: moderation. A few drops of a very dilute iodine solution in the watering can, used from time to time, is more than enough. Too much would be counterproductive and could weaken the plant.
Water and aspirin: a surprising but popular method
Water and aspirin: a surprising but popular method
Another tip often mentioned by natural gardening enthusiasts is a solution of water and aspirin. This method uses salicylic acid, a substance found naturally in some plants and said to help strengthen their resistance.
Simply crush a tablet in lukewarm water and then spray it lightly onto the leaves. Be careful not to get the flowers wet. This method should be used sporadically, as a one-time aid, and not as a regular treatment.
