Edgeworthia chrysantha

How much to water

Edgeworthia chrysantha is a plant which in the vegetative period should be irrigated often in order to keep the soil moist, ensuring correct drainage as it fears stagnation, therefore, for those in pots it is advisable to eliminate the saucer; for those in the ground it is advisable to form an insulator made of stones, shards and sand on the bottom of the hole to facilitate the filtering of excess water. It is sensitive to limestone, so it should be watered with fresh, rain or acidulated water. To avoid water stagnation, sand or pumice stone can be mixed with the earth, which will ensure good aeration of the soil. The plant should be watered when the soil is dry and regularly in dry periods, sprinkling water on the leaves to keep the foliage always moist and fresh.

It must always be remembered that its roots cannot withstand displacements, therefore its final position must be carefully decided at the time of implantation. More than the cold, it fears the icy currents, which is why it prefers sheltered locations, with abundant but not direct light in the hottest hours of the day. The ideal soil is for acidophilic, soft, rich in organic substances such as humus or mature manure, or based on peat, mixed with sand to ensure good drainage and avoid root rot. The substrate suitable for its cultivation is variable, those that ensure the best results are of the following type: chalky, fat, sandy and clayey.

How and when to fertilize


Let’s fertilize the Edgeworthia chrysantha frequently. We can administer the fertilizer by enriching the soil with manure, at the end of winter; or we can provide you with a fertilizer for flowering plants, every 20-25 days, with watering. If the shrubs are large, or cover a large area, we can use a slow release granular fertilizer for acidophilic plants every 3-4 months. In spring we prefer fertilizations rich in nitrogen and potassium, to facilitate the development of new vegetation and flowers. In late autumn or early spring, give some manure or slow-release granular fertilizer. The soil can be prepared by mixing two parts of soil rich in organic substance with a part of coarse-grained sand and a part of non-chopped peat.

Edgeworthia chrysantha: Exposure, diseases and remedies


Edgeworthia is a rather resistant plant to parasite attacks; more than anything else it fears the rotting of the roots caused by water stagnation and does not tolerate displacements from the place of planting. Often manifests a greater sensitivity to temperatures, very high or very low; for example, the spring climate, with a high temperature difference between day and night hours, and fairly frequent rains, can favor the development of fungal diseases, which must be treated preventively with a systemic fungicide, to be used before the buds become too much large; at the end of winter we also recommend a broad-spectrum insecticide treatment, to prevent the attack of aphids and scale insects; these treatments should be done when there are no blooms in the garden.
