A Guide To Growing Plants In Your Orangery Or Conservatory

If you have a bespoke orangery or conservatory, it might be in need of some extra interest at this time of the year. One of the best ways to make use of a glazed extension in all seasons is to return to its original purpose: cultivating plants. 

As the name suggests, orangeries were first built to grow citrus fruits in cooler climates, and conservatories are designed to conserve heat and maximise light exposure, which are ideal plant growing conditions. However, if you are new to the world of houseplants, getting started can be a rather daunting prospect.

Here’s a guide to help you transform your orangery or conservatory into a beautiful and tranquil oasis of greenery and flora. 

Low maintenance plants for complete beginners

If you are new to indoor plants or haven’t had much success with them in the past, then succulents and cacti are a good place to start. These species of plants are very low-maintenance and love sunlight, making them ideal for conservatories or orangeries. Look for options such as aloe vera and barrel cacti. 

They just need occasional watering to prevent the soil from completely drying out, but even if you forget to water them for several weeks they will generally be fine. Succulents are very popular and you can often find them for sale in supermarkets. For the best quality species, go to a dedicated plant nursery or garden centre that specializes in indoor plants. 

Citrus trees

Citrus trees are a classic choice for an orangery, as the name suggests. Orange, lime, and lemon trees will thrive in a bright sunny spot, and can be moved outside in warmer weather. Fiddle fig trees are another popular option, producing attractive large leaves.  However, the leaves are toxic to pets, so if you have an inquisitive cat or dog, they are best avoided.

Mature trees will take up some headroom, so they may not be an ideal choice for smaller spaces. Make sure the trees are planted in good quality soil, which should be kept moist but not overwatered. Rotate the plant regularly to ensure even growth, and avoid cold draughts or very direct sunlight. 

Healthy citrus trees not only add beauty and interest to the space, but will also bear delicious colourful and fragrant fruits in season. 

Orchids

If you are looking for a flowering plant, orchids are an excellent choice. They produce vibrant flowers in a variety of colours, and have elegant glossy leaves. They prefer bright light but not direct sunlight, so they are ideal for a north or east facing conservatory. 

Water them regularly with boiled water or rainwater, as tap water contains harmful chemicals. Keep the soil moist but not saturated, and do not leave the plant standing in pooled water. Moth orchids are considered the easiest variety to grow if you are new to this type of plant. 

Further considerations

Before purchasing any plants, assess orientation and light levels of your glazed extension. If it is south-facing it will be warmer and sunnier for example. Most conservatories will have good natural light, but if you have a smaller space or prefer to keep the blinds partially closed, this will affect the light levels. 

The general humidity and temperature of your extension is also important. Consider the levels of insulation and ventilation, and how you heat the space in winter and keep it cool in summer. 

Speaking to Good Housekeeping, Guy Barter, Chief Horticulturist at the Royal Horticultural Society says: “Conservatories work best if they don’t overheat in summer, so south-facing orientation needs ample ventilation installed and also external blinds that can be rolled down in bright weather from April until September.”

He adds: North-facing conservatories are better in summer, but the plants must cope with low light levels in winter. When it comes to conservatories, volume is important – the bigger the volume the more equable the conditions, meaning fewer fluctuations or extremes of temperature, which in turn means happier plants.”

When curating your plants, aim to have a mixture of tall and shorter plants, and make use of decorative pots, basket weave, and hanging baskets to create an interesting and harmonious visual arrangement. This will create a calming and inviting environment to enjoy nature all year round.
