The temperature condition that is best for spiraea bumalda growth is between 68 and 77 degrees Fahrenheit. This plant prefers moist soils and does not tolerate drought well. If the temperature gets too hot, the leaves will start to wilt and the plant will go into dormancy.
Ideal humidity condition for this plant is between 40 to 50%. If the humidity level drops below 40%, the leaves will begin to turn brown and crispy. If the humidity level rises above 50%, the leaves will begin to yellow and drop off.
For the fertilizer, this family of plant prefers a 10-10-10 fertilizer with micronutrients. The amount of fertilizer will depend on the size of the plant. For a small plant, use 1/4 teaspoon of fertilizer. For a medium size plant, use 1 teaspoon of fertilizer. For a large plant, use 1 tablespoon of fertilizer.

If the soil is too wet, the roots will rot.
Pruning your Spiraea bumalda regularly will encourage fresh growth and maintain its compact shape. To prune, simply cut back any shoots that are longer than youd like them to be. You can prune in early spring or late summer/early fall.
Propagation is typically done by rooting softwood or semi-hardwood cuttings taken from the tips of new growth. The cuttings should be 4-6 inches long and taken from healthy, disease-free stems. Before planting, strip off the lower leaves and dip the cuttings in rooting hormone. Plant the cuttings in a well-drained potting mix and keep the soil moist but not wet. Place the pot in bright indirect light and wait for the cuttings to take root, which usually takes 4-8 weeks. Once the roots are established, transplant the seedlings to their permanent location.
Usually, the plant growth rate occurs in the spring and summer. However, the plant can grow and bloom sporadically throughout the year in warm climates. The plant produces pink or white flowers. It can grow to a height of 6 feet and a width of 8 feet.
Common problems for this kind of plant are powdery mildew and leaf spot. These can be controlled with fungicides. Other problems include aphids, scale, and Japanese beetles. These can be controlled with insecticides.
