I have flirted with geraniums for several decades but never achieved the full satisfaction of a great display. Now I have a new plan to dedicate an area in the garden, dare I call it a zone? to some of these colourful plants. To give me an incentive to dedicate time and effort I have given it a name Pelargonia as I thought Geraniumistan was going to confuse the issue with cranesbill geranium or hardy geraniums.
As you can see from the search link I have blogged on 67 occasions about pelargoniums and geraniums over the Gardeners Tips years.
Frost Tender Pelargoniums
- After several good years I got careless one weekend and lost some good growth and suffered several set backs after an air frost. A similar event took place 6 years ago and that was at the beginning of June.
- Remember if your pelargonium stems get frosted then the plant will die and not recover!
- In the North of England there can be frosts late in May and early June. In Scotland and on high ground keep your thermometer handy whenever frost is threatened.

Zonal geraniums are more accurately called ‘Pelargoniums’. The zonal is named for the distinct bands of colour around the leaf. On the example below 3 distinct shades are obvious even in a black and white image. These distinctive colours and patterns are quite sought after and some varieties are grown for the leaf shade alone.
Pelargonium House Plants
- If you are worried about frost, geraniums make fine house plants. They can be kept in flower throughout the year and the flowers can be picked for a small vase. If you time it right when several ‘pips’ are showing full colour they can last a couple of weeks as the other pips keep opening.
- Regular weekly feeding of high potash feed with an occasional nitrogen booster will grow a substantial specimen.
- Pinch out the growing tip in April and June to get bushy plants with more flowers.
