Spiraea 'Magic Carpet' problems — and how to fix them
Spiraea 'Magic Carpet' (Spiraea japonica 'Magic Carpet') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Loss of orange-red spring colour
Insufficient light is the primary cause. Ensure full sun; shade turns the vibrant foliage colours to flat green.
Leaf tip scorch
Colourful foliage is susceptible to tip-burn during drought. Water consistently and apply mulch to buffer soil moisture.
Powdery mildew
Favoured by dry roots and high humidity. Maintain consistent soil moisture and ensure good air circulation.
Aphids
New growth in spring is vulnerable. Monitor closely and treat with insecticidal soap or a water jet at first sign.
