Best Conditions to Planting Grevillea Ivanhoe
Soil & Drainage
Grevillea Ivanhoe grows best in well-drained soils and really doesn’t like to be waterlogged, so make sure your garden soil is free-draining to prevent the possibility of root rot. Sandy loam is the ideal soil structure for Grevillea Ivanhoe (which will briefly hold its shape when squeezed in your palm, and crumble back out when released).
If you’re stuck with clay soil, you can dig your soil to 45 cm deep, and 3-4 times the width of the root ball, and backfill with sand, grit, compost, or a mix of your heavy soil and soil improver.
Light & Temperature
Grevillea Ivanhoe grows best in full sun, so try to find a spot with at least six hours of direct daily sunlight. While it can withstand cold snaps, strong chilly or salty winds are challenging for these native shrubs, so avoid planting them as a windbreak, and find shelter for these shrubs if you live near the coast.
Water Requirements
Grevillea Ivanhoe is drought-tolerant so it’s essential that you avoid overwatering. Rather than watering weekly, or on timed irrigation, only water Grevillea Ivanhoe manually when the soil is visibly dry on the surface, and avoid watering altogether through winter.
Propagating Grevillea Ivanhoe
Propagation from seeds
Grevilleas can be propagated from seed, but it can be a slow process, and Ivanhoe is no exception. If you fancy a challenge, start by sowing the seeds in a well-drained soil mixture in the autumn (sieved garden soil or a sterile seed compost will work well).
Keep the soil moist and warm. Your seeds should germinate after about 4-6 weeks.
How to Propagate Grevillea Ivanhoe from Cuttings
The quickest way to propagate Grevillea Ivanhoe is from cuttings, and even if you’ve never tried growing plants from cutting before, it roots reliably. Take semi-hardwood cuttings (young semi-green stems from last year) in the spring, and strip the lower leaves so you’re left with a clean 15-20cm twig with a couple of leaves at the tip.
Dip the base of the cuttings in rooting hormone powder and plant them in a 50/50 mix of perlite and compost. Keep the soil moist and warm, and the cuttings should root within four to six weeks.

Mulching Needs
Mulching Grevillea Ivanhoe can help to retain moisture and suppress weed growth. Use a coarse mulch such as bark chips for a generous and affordable mulch around the base of each plant, making sure it isn’t in contact with the stem.
Refer to our comprehensive guide on mulches to discover more types and their uses.
Grevillea Ivanhoe fertiliser
Grevillea Ivanhoe doesn’t require regular fertiliser, but an annual application of slow-release native plant food has a big impact on flowering later in the year.
Grevillea Ivanhoe Pests & Diseases
Grevillea Ivanhoe is a hardy plant that rarely succumbs to pests or diseases. Like nearly all Grevilleas, its most regular problems are caused by overwatering, and if you spot signs of wilt or bud drop, just slow down on water, try to regulate feed, and most pest and disease problems will balance out with time.
