Geraniums (bot. Pelargoniums) are the most popular bedding plant I know. They give color throughout the summer months to our patios, balconies and flower beds. The variety of geranium plants available nowadays makes them a great choice for your pots and containers, hanging baskets, window-boxes or flower beds.

They are available in many colors from white to red, shades of pink and purple or salmon. The flowers can be single or double. Just keep in mind that the double flowers don't cope with rain as well as the single ones do.

You have the choice between different types of geraniums: the trailing Geraniums also called ivy-leaf Geraniums or the upright Geranium varieties referred to as zonal Geraniums. You can grow Geraniums outdoors or indoors in conservatories or on sunny window-sills.


How To Care For Geraniums

Geranium care is not rocket science. Like all other plants they need regular watering and feeding. Avoid over-watering and keeping the rootball too wet as this can cause root-rot. Use a good quality fertilizer once a week.

Choose a sunny spot for Geranium plants. They like to be in the sun for most of the day. In a shaded spot they won't produce many flowers and they tend to become leggy.

How To Deadhead Geraniums

Deadheading Geraniums is important to keep them flowering over a long period. It also helps to avoid fungal diseases like Botrytis, particularly in damp weather.

A lot of people make the mistake of just removing the actual flower. This way you will end up with an ugly yellowing stem. Instead remove the stalk of the flower as well. It is usually a couple of inches long. Break them off where they attach to the plant. They break off easily so there is no need to use scissors or knifes.

Growing Geraniums in Containers

Bedding Geraniums are great container plants. The upright Geraniums can be used as a center piece of a larger container. They combine very well with trailing annual flowers like Lobelia, Bacopa, Millionbells (Callibrachoa), Bidens or Verbenas.

The trailing geraniums (ivy leaf Gernaium) can be grown in hanging baskets, window-boxes or tall urns. Three plants are enough for a 13 inch basket or pot. You can use a few filler plants like Lobelia, Viola or Alyssum with them.

And don't forget: regular feeding and watering is a must if you want a great looking summer display!

How To Overwinter Geraniums

For overwintering you need a glasshouse or a cooler but bright room. They need to be overwintered frost-free. The ideal temperature is between 41-47 degrees F. Keep the plants drier during the winter months. In the spring cut the plants back by about half.

This material can be used for propagating geraniums. Take cutting and insert them into potting compost. Re-pot the plants into new potting soils and start feeding and watering again.

Dealing With Pests and Diseases

Greenflies can become a problem. An organic pest spray will take care of them. An organic fungicide will help to protect your Geranium plants from fungal diseases.

Growing Geraniums Indoors

Pelargoniums are great plants for hot window-sill or conservatories. In these hot spot you often have trouble growing other house plants because they burn from the hot sun. Geraniums though tolerate that well and they flower!

Geranium care and maintenance is the same as above. Just keep in mind that the plants might require a lot of watering if they are placed on a hot window ledge.
