Pruning can be a bit tricky with Nandinas, but it's a great way to encourage new growth. Most varieties will sprout new shoots when cut right back, even to stumps at ground level.

However, this relies on the plant having healthy stems at the outset. If the stumps have any dead wood or they're too old (more than five years), they may not shoot or may only shoot on one side.

Severe pruning is best done from late autumn until early spring, and you can expect multiple shoots to grow from each stump. This is a great time to prune, as the plant will have a chance to regrow before the heat of summer.

Nandinas grown in heavy shade environments may struggle to re-establish when cut back severely, so be gentle with them if they're not getting enough sunlight.

Growth is a crucial aspect of Nandina care, and understanding the signs of growth issues will help you keep your plant thriving. Stagnation, lack of fruiting, leaning, leggy, and etiolated growth are all signs of underlying problems.

Regularly checking soil moisture is key to maintaining healthy growth. Adjust your watering schedule based on these readings to ensure your plant gets just the right amount. Fertilize during the growing season to provide essential nutrients that promote healthy growth.

If your plant isn't getting enough light, consider relocating it to a brighter spot. In partial shaded conditions, Nandinas tend to become less colourful and more open in their growth habit. They may also drop their central leaves, resulting in a plant with mostly exterior foliage only.

Here are some common growth issues to watch out for:

Each of these symptoms is a piece of the puzzle, indicating potential issues from water stress to nutrient deficiencies. Monitor your plant closely and take action if you notice any of these signs.

Propagation is a crucial step in plant care, and it's essential to understand the different methods and techniques involved.

You can propagate plants through stem cuttings, which is a popular method for plants like succulents and cacti. This method involves cutting a section of stem, allowing it to dry for 24 to 48 hours, and then planting it in well-draining soil.

Some plants, like African violets, can be easily propagated through leaf cuttings. Simply snip off a healthy leaf, remove lower leaves, and plant it in moist soil. Water thoroughly and keep the soil consistently moist.

Rooting hormone can be used to increase the chances of successful propagation. It's a powder or liquid that's applied to the cut end of the stem or leaf, helping to stimulate root growth.

For plants like roses, propagation is often done through grafting, which involves joining a piece of stem from one plant to the root system of another. This method is commonly used in commercial rose production.

Pruning Nandina varieties can be done right back to the ground level and they'll still sprout new shoots, but only if the stems are healthy to start with.

If the stumps have dead wood or are too old, they may not shoot or may only shoot on one side. This is especially true for stumps that are more than five years old.

Severe pruning is best done from late autumn to early spring, and you can expect multiple shoots to grow from each stump.

Nandinas grown in heavy shade may struggle to re-establish after severe pruning.

A common mistake with Nandinas is trimming them to shape, which can result in an imbalanced plant and lose their delicate appeal.

Cutting a single cane will only result in one or two more canes growing, making for a flimsy and weak plant if done with shears.

Suggestion: Cutting Back Nandina

Watering and soil are crucial factors in maintaining the health of your Nandina. Nandinas prefer a soil pH within the range of 6.2 to 7.5, which means they can tolerate both acidic and semi-alkaline soils.

To ensure the optimal soil pH, it's recommended to do a test before planting, and adjust the pH accordingly. If the pH is too low, dolomite lime and shrub fertiliser should be applied, while a pH that's too high requires small amounts of soil acidifying fertiliser.

Use only potting mix when growing Nandinas in a container, as soil and mixes containing both soil and potting mix can cause poor results. A generous watering every second day during summer, or every third day if the soil is heavier, will keep the foliage fresh and promote active growth.

Nandinas prefer a soil pH within the range of 6.2 to 7.5, meaning they can tolerate both acidic and semi-alkaline soils.

If your soil pH is too far from this range, it can lead to nutrient deficiencies and toxic levels of other nutrients, causing the plant to become sick or even die.

A pH less than 6.2 requires sparing amounts of dolomite lime to be applied, along with shrub fertiliser.

A pH above 7.5 needs small amounts of soil acidifying fertiliser to be added, which should be thoroughly mixed into the soil before planting.

It's essential to test the soil pH before planting to avoid any potential issues, and a retest should be done after four weeks to make any necessary adjustments.

Using shrub fertiliser is sufficient once the pH is in the optimum range.

A fresh viewpoint: Nandina Planting

For container plants, only potting mix should be used to avoid poor results. This is because potting mix is specifically designed for containers and doesn't retain too much moisture.

People often try to cut corners by using soil or mixes with both soil and potting mix, but this can lead to compacted soil and weeds.

Soil is not suitable for containers because it tends to become compacted and contains weeds. Planting with compost is also not recommended as it holds too much moisture.

The Plant Company's nursery grade potting media is a good option, as it's pre-loaded with the correct amounts of fertiliser and micro-nutrients to keep the plant sustained for 12 months. After 12 months, simply add a couple of fertiliser tablets to keep the plant fed.

As you're dealing with nandina problems, it's essential to consider a few special factors. In areas with high humidity, nandina's invasive roots can cause significant damage to nearby plants and structures.

Nandina's invasive roots can also outcompete native vegetation, leading to a loss of biodiversity. This can have a cascading effect on local ecosystems.

If you're planning to remove nandina from your property, be aware that its berries are toxic to humans and pets. This makes it a significant concern for families with pets or young children.

Nandina can form dense thickets in southeastern forests, displacing native plant communities.

This invasive plant can be particularly problematic for birds, who will gorge on its berries if no other foraging options are available.

In fact, research shows that multiple bird species, including cedar waxwings, have died after eating too many N. domestica berries.

The berries are also poisonous to people, pets, and wildlife, making Nandina a hazard in areas where it's not supposed to be growing.
