Citrus Cultivation Guide

Intro
Citrus plants have become a popular choice in the UK over recent years. But be aware that success depends on suitable surroundings. A conservatory or greenhouse is a must for winter.

Light
Citrus plants require very good light levels at all times. During summer, be aware that young foilage will get scorched unless the plants are placed in a lightly shaded area. During winter they must be placed in a greenhouse or conservatory.

Temperature
In general Citrus plants prefer a cooler period in winter, so very little growth takes place.
Avoid night time temperatures falling below 7 degrees C (45F).

Watering
Summer: Water freely.
Winter: Water moderately.
Hard water can cause leaves to yellow. Occasional feeds with sequested iron will sort this.

Feeding
Citrus plants are heavy feeders. Seaweed based feeds are great.

Compost
Citrus plants like soil based compost like John Innes number 2. Add perlite or bark for good drainage.

Humidity
Mist the leaves in early morning during summer months.

Pests
The following pests can be controlled with the application of insecticides;

Blackfly and Greenfly : These will attack young leaves and the stems.

Red Spider Mite : You can detect the presence of these by yellowing leaves, fine webbing between leaves and mottling of leaves.

Scale Insects : look like brown scales on the leaves and stems.

Repotting
Its best to repot your Citrus plant between April and June.
Always use the next size up.
Do not feed for 5-6 weeks after repotting.
Replace the top 2 inches of compost on the years when you dont repot.
