Propagating Grevillea ‘Coconut Ice’

You can quite easily propagate your own Grevillea ‘Coconut Ice’ from semi-hardwood cuttings that have been taken towards the end of summer. This type of cutting would be a section of the plant where the new growth for the season has started to firm up.

The base of the cutting should ideally be hard, and then the tip soft. When taking your cuttings, aim for a length between 10 and 15 cm and be sure to cut just underneath a node.

Take off the leaves on the lower part of the cutting as well as the tip, and then make a cut about 2 cm long on the side of the base of the stem. Dip this cut end into rooting hormone and then plant your cutting into a container with any normal cutting compost.

Offer the cuttings enough water and ensure the compost stays moist until the cuttings have rooted themselves. In the winter time you can get rid of any dead leaves and only water the cuttings if the compost feels dry.

When spring arrives, you can then start hardening off your Grevillea ‘Coconut Ice’ cuttings.

How to Care for Grevillea ‘Coconut Ice’

Sunlight

Grevillea ‘Coconut Ice’ can grow in full sun or part shade, but you’ll see the best flowering in full sun.

Watering

You can water your Grevillea ‘Coconut Ice’ regularly for the first 8 to 12 weeks while the shrub is establishing itself. After that period, you can then move to occasional watering. This grevillea doesn’t enjoy lots of rain or roots that are wet.

Soil

Grevillea ‘Coconut Ice’ can be flexible when it comes to soil type. It just needs to be well-draining. A clay loam or sandy soil will work well and aim for a neutral pH. If you’re dealing with a heavy soil, you can add in perlite or vermiculite to help air circulation.

Fertiliser

We recommend using a native or low-phosphorus fertiliser for your Grevillea ‘Coconut Ice’. A good time to do this is when you see buds starting to form. Fertilising after pruning the shrub also helps recovery.

Pruning

Grevillea ‘Coconut Ice’ can handle quite a bit of pruning. The best time to do this is after flowering has finished. The pruning process helps to stimulate new growth.
