How to grow Garden Gladiolus 'Rio de Janeiro'
Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Rio de Janeiro is thought of as half hardy, so it will need cloching or fleece protection when the temperature dips. Rio de Janeiro requires a soil ph of 6.7 - 7.0 meaning it does best in weakly acidic soil - neutral soil.
Growing Rio de Janeiro from seed
Look to ensure a distance 7.02 inches (18.0 cm) between seeds when sowing - bury at a depth of at least 4.29 inches (11.0 cm) deep.
Transplanting Rio de Janeiro
Ensure that temperatures are mild (minimum night temperatures should be around 2°C / 36°F) and all chance of frost has passed before planting out, as Rio de Janeiro is a half hardy plant.
Harvesting Rio de Janeiro
Expect harvests to start to occur in mid summer.
