Lavender in the Subtropics

Maybe it’s my French heritage but I just love lavender, but in subtropical climates it can be tricky to work out which ones are the most successful to grow.

Here in this segment of Blooming in Brisbane from Season 3 I talk about what lavenders are worth growing. From Italian to French I have look at different varieties and their cultivars, their cultural care, pruning and what are some of the benefits of growing lavender.

Lavandula dentata ‘French Lavender” is by far the best performer in locations where hot humid summers are the norm, it’s fat blue/mauve flowers are magnet for bees and butterflies and they also can picked as fresh flower for vases and or dried as well, for a longer lasting posie.

For those that have dreams of replicating the fields of English lavender Lavandula angustifoila as seen in Tasmania and northern hemisphere gardens, dream on, these lavenders will only cause disappointment due to their disposition for dying off in sections and a serious lack of flowers, due to a sever dislike of the combination of heat and humidity.

Top Lavender Tips in the Subtropics

1: Full sun
2: Good drainage
3: Sweet soil pH 7-7.5
4: Prune little but often is best in place of one big prune
5: Choose appropriate varieties and species
6: Use a fertiliser high in potassium and phosphorus for good flowering
7: Dust foliage with dolomite during extended periods of rain and humidity to prevent sweating off occurring throughout the bush. (dying off)

dried lavender
Dried lavender will last for ages and can be used in drawers and cupboards to scent clothes and ward off moths.
