About this plant
A small tree or a large shrub from the Kermadec islands, New Zealand. It is a rather solid-looking tree with a rounded fan shape when mature. It maintains a shrubby habit for some years before attaining a state of tree-dom. The leathery leaves are oval, smooth looking, coloured dark green with a paler midrib. It flowers on and off for much of the year so there are usually some blooms. which form a fan of lively red bottlebrushes with many slender petals. The nectar is held at the base of the flowers, in small cups, and is drunk by birds. It can be pruned to size for growing in containers. It is found growing naturally in coastal regions, taking salt spray and dry and poor soil, though does suffer from frost damage when young. General care: If grown in a greenhouse or conservatory prune to size if needed. Feed monthly whilst in growth with general purpose fertiliser. Water regularly in summer when in growth, but just give the occasional watering in winter to prevent the soil desiccating.

Spring
Spring - late · Outdoors
Feed with sequestrol
If plants are acid loving and grown in soil with little acidity, or in a container, or are watered with limey tap water an annual feed with sequestrol (iron chelate) is highly beneficial. Follow guidelines on the packet. Will also 'blue-up' hydrangeas.
For hydrangeas that have good blue flowers in acid soil, this product can be used with alkaline soil to turn the flowers blue. This is most effective when the soil is neutral or just slightkly alkaline.
Spring-Autumn · Outdoors
Water until well established
Until well established, plants in the ground should be watered deeply at regular intervals after a dry period. This is likely to be 1 and 2 weeks without rain. Check plants in pots more frequently, especially in hot weather.
Summer
Summer - early · Outdoors
Feed a general fertiliser
Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.
Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.
Planting & general
Outdoors
Water with rain water
This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
Compost · Planting
Ericaceous compost
This plant requires acidic (ericaceous) soil. Where the soil is not acidic, or when planting in pots, use an ericaceous compost.
