Indoors

Start your geraniums indoors, using potting soil with peat moss at the bottom of the container. If you keep your geraniums potted, use an all-purpose liquid plant food every two weeks.

Outdoors

Transfer your geraniums outdoors after the last frost of the season and after the soil has warmed. Transfer the plant soil and all to your garden bed or repot if necessary.

Fertiliser

Fertiliser is plant food for outdoor plants. Fertilise your geraniums at least once a month, if not biweekly. Use a water-soluble fertiliser, such as 15-30-15.

Compost

Many people are making compost for plant food these days. Allow plant based wastes to decompose for a nutrient-rich compound that your geraniums will love.

Water

Geraniums needs lots of water. Make sure you water outdoor plants regularly. For indoor geraniums, water when the top 2 inches of soil feels dry.

Sunlight

Healthy geraniums require six to eight hours of sunlight a day. Outdoor geraniums should be planted in full sunlight, except in hot areas, where they can be planted in partial shade. Indoor geraniums need just as much light.
