Growing Proteas In Pots

Growing proteas 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.

What is the best potting mix 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 often do you water proteas in pots?

Water your established plants every two to three weeks. If your plants are just starting out, water them more frequently. Proteas can stand a range of temperatures, from 23 F.

How long does proteas take to grow?

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.

Do proteas have deep roots?

Proteas can be staked but prefer to spread naturally (often growing on their elbows). Prune plants back as you cut flowers. Proteas have fine roots near the surface, so be careful not to cultivate too deeply.

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).

How do I make my soil more 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.

Is Epsom salt good for Proteas?

Proteas originate from South Africa. They have a low tolerance for artificial fertilizers. Applications of superphosphate will kill proteas. However, they require magnesium, and this can be applied as Epsom salts, scattered over the root areas and then watered in well during spring.

Is Seasol good for Proteas?

PowerFeed is safe to use on all Australian native plants and Proteas. It provides the perfect balance of essential nutrients and amino acids to boost growth, health and vigour, but is low in phosphorus to cater for the needs of phosphorus sensitive plants. www.seasol.com.au.

Do proteas like fertilizer?

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.

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.

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.

What month do proteas flower?

Species	Production period
Species Protea compacta	Production period May to October
Species Protea repens^a	Production period February to July
Species Leucadendron daphnoides	Production period May to July
Species Leucadendron discolor^b	Production period July to November

What fertilizer for proteas?

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.

Are proteas hard to grow?

They do well in poor soils, and they don't mind salty, coastal areas. But the humidity will knock them around. If you are north of Brisbane it will be difficult to grow a Protea. But they'll do really well anywhere else, as long as it's not too frosty.

Do Proteas like full sun?

To grow proteas you need full sun and reasonable drainage. If you have clay soil, plant on a slope or a raised bed and add gypsum.

Can Proteas be cut back hard?

Proteas will tolerate severe pruning, but generally only cut back to wood with green leaves. Severe pruning usually affects subsequent plant growth and flowering may be restricted for one to two years.

Do Proteas transplant well?

They have surface, matting roots that are easily damaged. This makes them very unlikely to survive transplanting, so choose your spot carefully. – Proteas are pretty tough once they're established.

Will proteas grow in shade?

While they perform best in full sun, Proteas can handle light shade.

Can I grow Protea from a cutting?

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.
