Dune Marsh-ElderIva imbricata

Water regularly when the top 2-3 cm of soil are dry, especially during establishment and dry periods. Iva imbricata, being a coastal plant, tolerates some dryness but performs best with consistent moisture.

Avoid waterlogged conditions, as this can lead to root rot. Reduce watering slightly in cooler months.

Prune in late winter or early spring before new growth begins. This helps maintain a desirable shape and encourages denser foliage. Remove any dead, damaged, or crossing branches.

Light pruning can also be done after flowering to tidy up the plant and promote a bushier habit. Avoid heavy cutting back into old wood.

Propagation is typically done by semi-hardwood cuttings taken in summer or by seed. Sow seeds in autumn or early spring.

Cuttings should be placed in a well-draining potting mix and kept moist in a warm, humid environment. Seeds may require stratification for optimal germination. Both methods are effective for increasing plant numbers.

Repot young plants every 1-2 years in spring as needed, usually when they become root-bound. Use a well-draining potting mix, incorporating sand or perlite to improve drainage.

Mature plants generally prefer to be slightly root-bound and may not require frequent repotting. Choose a pot only slightly larger than the current one.
