Hebes are plants that come from New Zealand, but most plants nowadays come from South America and Australia. They are showy plants best displayed in a predominant position.

People want to grow Hebes for two reasons; the colourful leaves that they have and the mid to late summer flowers that they produce. The flowers are produced en masse but they come with a price that most of them are borderline hardy, taking a temperature no lower than minus 5 degrees Celsius.

It is advised to grow small-leaved varieties in containers, but if you grow large-leaved species that you cover them with horticultural fleece to protect them from cold frosts in hard winters.  Most container-grown species will not grow more than 90cm in height.

 HOW TO GROW HEBES IN CONTAINERS

You can pot Hebes in containers any time of the year, but it is better to plant them during the growing season. This will allow ample time for the Hebe to form a strong root system before it is exposed to the cold and will give it a chance to form a strong and sturdy plant.

Use a 30cm diameter container or more depending on the size of the plant will get to and fill it with a mixture of 70% multipurpose compost by volume and 30% by volume of horticultural grit. This will ensure that the growing media is free-draining, avoiding potential loss due to overwatering.

Dig a hole that is twice the size of the original root ball and place the plant in it.   Start to backfill, ensure the level is the same as the level it was in the original pot- not shallower or deeper.  Fill any gaps with more compost and firm the plant in. Water it in and make sure that in the first year of growth that it is well watered. This will make sure that the plant will establish quickly and healthily.

As they tend to be quick growing, you may need to repot every year or two, depending on the species that is planted.

Every spring give a feed of slow-release fertiliser to give a boost for the forthcoming growing season. Keep well-watered, especially so in hot summers, but make sure the growing media is never soggy. Water when 5cm below the top of the surface of the compost feels dry to the touch when you stick your finger in.

HOW TO PRUNE HEBES

Hebes shrubs will grow leggy over time, which will give an unsightly look. This is why you will need a regular pruning regime in mid-spring.  At this time, you will need to shear lightly to improve the look and to help it bush out and produce new, healthy shoots.

Hebes, in general, are short-lived, lasting no more than 10 years in pots. This is why pruning is essential, as described above. It is also important to deadhead the shrub as this will help to extend the flowering period. If your Hebe has become too straggly, you can cut it to within 30cm of the ground as this will lead the plant to rejuvenate and have better new growth.
