Lime trees are a type of citrus related to lemons and oranges. They grow on ornamental evergreen trees usually spanning between 1.5 meters and 1.8 at full maturity. Lime trees are not particularly resistant to the cold weather of Britain so they work best when grown in pots and containers so that you can put them outside at the end of spring and summer and then bring them inside your home or heated a greenhouse for the winter.

It is important to note that most lime varieties are significantly less tolerant of cold than lemons or oranges. You will need to provide a bit more warm in the winter for limes. That said if you are willing to go the extra mile, your lime trees will produce white, fragrant flowers as well as aromatic citrus foliage. These trees are self-fertile, so you only need to invest in one to get delightful limes.

Limes need a lot of sunlight just like any Citrus plant, but they dislike central heating and as a result, do best when grown in pots and positioned in a bright position such as a windowsill but not above a radiator which is a common mistake.

How to Grow lime trees in pots

Lime trees, as mentioned, need a warm, sunny place outside starting from the middle of June throughout August. They need a sheltered location what prevents damage from severe wind. In the autumn and winter, they need a well-lit position indoors, and they do best if you bring them in a conservatory or a greenhouse.

Ideal temperatures range between 10 degrees and 13 degrees in winter

Ideal temperatures range between 10 degrees and 13 degrees at a minimum. Temperatures below 10° Celsius can cause damage to your lime tree so try and position in a nice bright warm room. If for some reason you have them outdoors and the temperatures look like they are going to reach those levels, you can add a layer of horticultural fleece around the plant to protect it, especially at night but they should really be indoors before this.

Choosing the best compost for limes

The compost you should use is a potting compost such as John Innes Potting Compost mixed with 30% grit got improved drainage, or a ready to use citrus compost if you want to take the easy route. When you first plant your lime tree, you want to find a container which is twice the size of the root ball. The material is not of particular importance. Plastic works just fine and is much lighter than wood or ceramic, which makes it easier to move in and out throughout the seasons.

Planting the lime tree into its new pot

When you plant your lime tree, fill the container with the citrus compost or the potting soil around a third. Carefully remove the plant from its container to expose the root ball and put it in the new container so the top of the root ball is where the compost with reach. Only plant them to the original depth they were in their original pot.

Next back still the container with the remainder of the compost and firm around the edges of the pot to remove any air gaps but be careful not to compact the soil too much.

Citrus lime tree care

General lime tree care

It is best to purchase a new citrus lime tree in spring or summer so that it has time to acclimate to your conditions before the onset of winter temperatures.


You should water your lime tree freely during the summer but be careful not to let it sit in water. Standing water in the container can lead to root rot. When autumn starts, reduce the frequency of watering, allowing the compost to dry out partially on the surface in between each water.

One of the most common problems people have with lime trees in pots is over-watering, especially in the winter. If possible use lukewarm water, as cold water can shock the roots, it is best to water early in the morning or later in the evening to prevent evaporation.

Feeding limes

Lime trees like all citrus trees are voracious eaters, so they need good food. When you first plant your lime tree, you should add fertilizer and then water immediately so that the fertilizer doesn’t burn the plant. Between March and July, you should use a high nitrogen liquid feed and then switch to a balanced feed until October.

You can also buy citrus feed of which you can get both a summer and winter feed so its important to use the right feed.

Pruning lime trees

How to prune citrus trees. Most <a href=citrus trees only require minimal pruning by removing overcrowded branches and leggy plants can be pruned hard by up to two thirds. learn more pruning now” class=”wp-image-33109″ width=”500″ height=”260″/>

Lime trees can be reshaped in the winter to thin away overcrowded branches or to cut back tall stems to encourage bushy, lower growth. But other than this, they don’t need a lot of pruning on a regular basis. Once you have your lime tree for a while, you can prune back the tall, leggy portion by up to two-thirds to help encourage stronger, leafy growth. Remember though that many lime trees have vicious thorns, so it’s best to wear a good quality pair of gloves.

Repotting lime trees

Every three years or so, you might have to repot your lime tree if it starts to outgrow its container. Only repot once it outgrows the existing container and repot it into a container that is just slightly larger than the one it was in initially. If you have to repot do it in the spring so it got plenty of growing time to put out new roots before winter.

During the years that you are not repotting, you can remove the top 4 centimetres of compost and replace it with fresh compost on an annual basis.


Your limes will be ready to pick when the skin has reached a deep colour. If worth noting they can also be left in the tree for longer if you wanted for a more ornamental feature.


Like most other citrus trees, limes also have their fair share of possible problems from aphids, to diseases and even problems caused by overwatering.

  • If the soil lacks proper nutrients or remains excessively wet, it can cause the leaves to turn yellow. We recommend feeding with a citrus feed and reduce watering allowing the surface of the soil to dry out between waterings.
  • If you are over-watering, you have high temperatures in the winter or otherwise low temperature throughout the year it can cause the leaves to fall off. Again reduce watering and ensure they are not being exposed to cold such as next to an outside door or near a window you have open in winter.
  • If the flowers are falling, it could be the result of low temperatures, lack of nutrients, erratic watering, or low light levels. Again these are all problems that can be controlled through proper care.
  • If you aren’t getting a lot of fruit, it could be the result of dry compost or low humidity.
