Growing protea

Protea plants are not for beginners and not for every climate. Native to South Africa and Australia, they require heat, sun, and extremely well-drained soil. If you'd like a little bit of a challenge, though, protea flowers are beautiful and very unique.

How long does a Protea take to grow?

Growing proteas is a long-term investment. The initial selection of species is critical, since substantial product will not be harvested until two or three years (leucadendrons) to three to four years (proteas and leucospermums) after planting.

What zones can Protea grow in?

The protea plant is hardy and evergreen with USDA hardiness zones between 9 and 12. This makes it ideal for warm climates where it can thrive in just about any soil.

How long does it take for Protea to bloom?

Also, Protea take 5-6 years to flower from seed or cutting, so we usually suggest buying a 1 or 5 gallon size Protea from a nursery. Keep seeds in a cool, dry place until Autumn as planting seeds in fall ensures they grow strong enough to withstand summer heat.

Where do Protea grow best?

For growing, Proteas must have a full sun location with good air movement around the plants. The single most critical factor in growing Proteas is to provide adequate water drainage; if the soil drains well, good results will usually be achieved.

What is the lifespan of a Protea?

The spe- cies grows into a tree, 3–8 m in height, with a stout trunk and a crown 3–10 m in diameter with individu- als having a maximum lifespan of 50–70 years (Rourke 1982).

Are proteas hard to grow?

They are tough and hardy evergreen plants, will thrive in exposed positions with poor soils, and are also both heat and cold tolerant (from -6° to 40°). In terms of their preferred climates, they'll grow in most regions except for the more humid zones.

Do proteas grow well in pots?

Smaller variety Proteas are ideal for container gardening It is possible to grow the smaller varieties of Proteas in containers using a coarse, well-drained native potting mix. Keep the plants in a sunny position with plenty of air circulation. Avoid over-fertilising or letting the container dry out.

Why do my proteas keep dying?

Most diseases that impact Protea are fungal infections typically due to a lack of air circulation, over-watering or high atmospheric humidity. Telltale signs of fungal infections include leaf spots, brown or black leaves at the tips of a stem, flower discoloration or rapid plant death after a heat spell.

How do you prepare soil for proteas?

Proteas prefer a nice sandy loam or open soil. Some Proteas are less fussy and are quite happy in a heavier soil although they will not survive in heavy clay soils. If you do have heavy soils it will be necessary to first mound the soil to improve it and then dig in compost and gypsum to break up any residual clay.

How do you make soil acidic for proteas?

It might be a good idea to amend the potting mix with aluminum sulphate to lower the pH. Proteas like very well-drained soils with a pH of 3.5-6.5. A good mix would be 1 part bark, 1 part pumice, 1 part sand.

Can I grow proteas from cuttings?

Proteas can be propagated from seed or cuttings. Only healthy plants not subject to stress may be used for cuttings, and no cuttings may be harvested from plants that display any symptoms of disease.

Should you cut dead flowers off proteas?

If the flower is left to die on the plant most gardeners will just remove the spent flower and leave these stems to grow. This is the fastest way I know to finish up with a straggly bush. Cut off the dead flower by all means but leave only 10 centimetres of stem on the plant.

Do proteas need pruning?

Regularly tip prune in spring and late summer for the first two years. The plants should flower in the third year and additional pruning should be done after harvest.

Why isn't my Protea flowering?

Why won't my Protea flower? Some possible reasons are: – It's too young – some take 3 years, and the king protea up to 6 years. – It's in the shade – proteas need sun all day to flower.

What fertilizer do proteas need?

We recommend Cactus Mix or Planting Mix. Refraining from fertilizing is a good bet. These plants have evolved to thrive in inferior soils. If needed, gardeners should use fertilizers with almost no phosphorus and low potassium.

Do proteas have deep roots?

Proteas live in very nutrient-poor soils - so there are very few minerals and elements to be had. That's why the first thing a baby protea does is grow its tap root deep down to where the ground water is.

Do proteas like Fertiliser?

It is best to plant proteas as small plants at the time of the first heavy autumn rains. Likewise it is best to plant proteas in an open position in slightly acid soil where the drainage is excellent. Do not fertilize them.

How do you maintain proteas?

Potted Proteas require daily watering during summer. IN THE GARDEN – Generally it is not necessary to feed Proteaflora plants planted in the garden unless your conditions are extremely severe, like in a sand belt. If so, adding compost and a slow release fertiliser, described as suitable for natives, is a good idea.

How many flowers does a protea plant produce?

Large, vigorous plants produce six to ten flower heads in one season, although some exceptional plants can produce up to forty flower heads on one plant. The colour of the bracts varies from a creamy white to a deep crimson, but the soft pale pink bracts with a silvery sheen are the most prized.
