Indoor plants are like a potting mix that is sandy and well-drained. Their rich flowers are produced by bright, indirect light and temperatures from 65 to 75 degrees Fahrenheit (18 to 24 degrees Celsius).

As previously said, the most important aspect of Leucospermum plant care is to keep the plant properly drained and aerated. Despite being drought-tolerant, the plant benefits from regular watering during hot, dry weather. Water early in the morning so that the plant has the whole day to dry before the chilly evening temps arrive. Keep the leaves as dry as possible by watering them at the bottom of the plant. 

You might wish to apply a covering of mulch to hold the soil dry and weeds at bay. Keep the mulch out from the plant’s base, though, to avoid rot and other issues caused by excessive wetness.

Indoor plants should only be watered extensively when the planting mix is completely dry. The foliage, like that of outside plants, should be maintained as dry as possible. Make sure not to overwater the pot, and never leave it submerged in water. flowering

Pruning a Leucospermum

Leucadendrons flower in the spring and continue to produce new growth all summer. It’s a good decision to remove spent blossoms when the plant is blossoming to maintain it clean and stimulate fresh blooms. Pruning back a leucadendron is best done after all of the blossoms have faded.

Pruning Leucadendrons isn’t a precise science, and the plants are tolerant to a lot of shearing. The most important thing to remember is that a wooden stem with no leaves will not produce new growth. As a result, it’s critical to leave some new, green growth with each cut when pruning leucadendrons.

Remove any wasted flowers from your leucadendron plant once it has finished blooming for the season. Cut back all of the green stems until there are at least four sets of leaves left. If you cut back too far, the stem will become woody and leafless, and no new growth will occur. You may trim the plant down rather significantly as long as there are still leaves on each stem.

Your trimmed leucadendron will put forth a lot of new growth in a more appealing, denser form during the growing season, and it should produce more blooms the following spring. The plant should not require pruning for another year, at which time you can repeat the cutting procedure.
