This Lomandra cultivar is a low-maintenance garden lover’s dream. It’s hardy, easy-care and looks stunning with its lime green strappy leaves and attractive flowering seed head spikes.

The flower spikes usually appear in summer and are fragrant.

Lime Tuff is a hybrid between three different Lomandra species that has been bred for its toughness and compact growth form. It will only reach a height and width of around 0.6 metres.

Light requirements

You can plant this Lomandra either in full sun or part shade and it will thrive. This means that you can even grow it under taller trees as an understory plant.

Temperature and humidity

This cultivar will grow in almost any climatic zone around the country. This includes cool, cool temperate, warm temperate, Mediterranean, semi-arid and sub-tropical zones.

Once established it can easily withstand heavy frosts and is also drought resistant. It even does well in coastal areas.

Soil requirements

You don’t have to worry about any special soil preparation because this plant will grow in a range of different soil types including both sandy and clay loams. It will even adapt to growing in poor soils.

Water requirements

Once your Lime Tuff is established, it shouldn’t need any supplementary watering except during long periods of very dry weather. However, young plants should be given a drink at least once a week for the first 12 weeks.

Fertiliser

I have a couple of standard Lomandra longifolia growing in my garden and never fertilise them.

However, young plants will benefit from a low phosphorus slow-release fertiliser after planting to help them become established fairly quickly.

Pruning

While no pruning is required, I do like to tidy up my plants once a year after the flower spikes have finished. I just remove the spent spike and any dead foliage from around the base of the plant.

As these plants grow from underground rhizomes, they will spring back if you have to cut them back quite heavily. However, in most cases, this is not necessary.

Mulching

Mulching the soil around your Lomandra is a good idea because it will help to conserve soil moisture. Ideally, you want to use a coarse mulch such as wood chips or stones but keep this back from the base of the plant a little.



Problems, pests and diseases

‘Lime Tuff’ is an extremely hardy cultivar and not prone to any pest attacks. However, in damp and humid regions, the plant might be susceptible to Phytophthora root rot.

This is a fungal disease whose spores can live in the soil for many years. It’s more prevalent in sub-tropical and tropical regions that receive a lot of summer rainfall. 

This disease can kill your plants if it takes hold. The first symptoms you’ll notice are leaves turning yellow after which your plant will die.

Making sure that the soil is well-drained is a good way to avoid any plants succumbing to this disease.

Common landscaping uses for Lomandra ‘Lime Tuff’

Lime Tuff is fast becoming a favourite with landscapers because it’s such a low-maintenance plant. It can be used as a border along driveways and paths. Space your plants around 60 cm apart for a nice dense coverage.



Apart from border planting, this cultivar is also handy for planting under taller trees in your garden as it doesn’t mind a little shade. This can help to create a pleasant understory planting to help suppress weeds and add another dimension to the garden.

Lime Tuff is also at home when planted in a rockery and surrounded by other drought-tolerant plants such as the huge range of succulents available at nurseries.

Can you grow Lomandra ‘Lime Tuff’ in pots?

Thanks to its compact growth habit, this plant is ideal for growing in pots and would make an attractive addition to your outdoor spaces.



You could use it to section off an area of your outdoor entertaining space or as a couple of feature plants next to your barbecue.

This plant can also be planted around your pool area. Or, select a couple of large attractive pots to position around the perimeter of your pool.

To grow ‘Lime Tuff’ in a pot, make sure that you select a large pot with a diameter of at least 30 cm. However, one twice that size will allow your Lomandra to reach its full size.

Make sure that the pot has a good amount of drainage holes so that your Lomandra doesn’t end up sitting in water.

Choose a potting mix that is made specifically for native plants as this will ensure that it doesn’t have a lot of phosphorus fertiliser in it. 

Once your plant is in the pot, give it a good drink and sit back and enjoy.

Potted plants will benefit from an annual application of fertiliser as the potting mix can become depleted of nutrients over time. Make sure that you select a native fertiliser that is low in phosphorus and apply this in spring to give your Lomandra a little boost.

If you’ve chosen a smaller pot to begin with, you can easily repot your ‘Lime Tuff’ if it looks like it wants to escape the pot. For this, choose a pot that is a couple of sizes larger than the current one and use a premium native potting mix.
