About soil condition, Grevillea Scarlet Sprite prefers well-drained soil in an open, sunny position. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This plant will require occasional maintenance and upkeep, and is best trimmed in late spring after flowering.
Just like other Grevilleas, the Scarlet Sprite does best with full sun but will tolerate some light shade, especially during the hotter months of the year. It's a tough little plant that's drought tolerant once established.
The temperature condition that is best for the growth of Grevillea scarlet sprite is between 50 to 70 degrees Fahrenheit. This plant is not tolerant to cold weather and should be protected from frost.
Ideal humidity condition for this plant is around 50%. If the humidity gets too high, the leaves will start to turn yellow and fall off. The plant will also start to produce less flowers. If the humidity is too low, the leaves will start to dry out and the plant will become less vigorous.
Regarding fertilizer, this type of plant does best with a low phosphorus fertilizer, such as 8-8-8. You can apply this fertilizer once a month during the growing season. Be sure to water the plant well before and after applying the fertilizer. As for the roots, they are generally not very deep, so you don't need to worry about digging too deeply. Just be sure to loosen the soil around the plant so that the roots can spread out and the plant can get the nutrients it needs.
Pruning is an important part of keeping your grevillea healthy and looking its best. You should prune your plant every few months to remove any dead or dying leaves or branches. You can also prune to shape your plant or to encourage new growth. To prune your grevillea, first, remove any dead or dying leaves or branches. Then, cut back any branches that are longer than you want them to be. Finally, shape your plant by trimming any branches that are too long or that are growing in an undesirable direction.
Propagation is best done from cuttings taken from new growth. Cuttings should be taken from the current season's growth and should be approximately 10-15cm long. Use a sharp knife or secateurs to take a clean cutting just below a node. Remove the lower leaves from the cutting, leaving 2-3 leaves at the top. Dip the cutting into a rooting hormone and plant into a well-drained propagating mix. Water well and place in a warm, protected position out of direct sunlight. Keep the soil moist but not wet and in 4-6 weeks the cutting should have rooted. Once rooted, pot into a well-drained potting mix and continue to grow on in a protected position.
Usually, the plant growth rate in the landscape is 1 to 2 feet per year. However, in optimum growing conditions, such as those found in Southern California, rates can approach 3 feet per year for a period of time. Once they are established, they will continue to grow and bloom for many years.
Common problems for this kind of plant are that it is drought tolerant, and it can be difficult to find in stores. Also, the flowers may not be as vibrant as they are supposed to be. The leaves may also be droopy and the plant may not bloom as often as it should.
