Convallaria japonica

The watering

As with any variety of Convallaria, also for Convallaria Japonica it is necessary to provide for the administration of the correct dose of water. A general rule has it that this plant does not particularly love too humid soils, so it is absolutely necessary to pay attention that particular water stagnations do not form which can seriously damage the root system of the plant. Normally watering can take place once a week, making sure that the soil is really dry between one operation and the next. In winter it is preferable to stop watering, since in this season the Convallaria Japonica goes into vegetative rest. After planting, it is necessary to water more to favor the

Cultivation and care

There is no type of Convallaria that is not extremely simple to grow. Convallaria Japonica is certainly no exception. Its cultivation starts from a good tilling of the soil and the integration of the latter with a good mature manure. The seedlings should be placed in small holes, about ten centimeters deep and with a density of about 10 specimens per square meter. The roots of Convallaria Japonica are quite fleshy. This is the reason why, in order to favor its taking root, abundant watering immediately after planting is essential. Given the very slow growth of the plant, maintenance is practically equal to zero. It is sufficient, more or less every 5 years, to provide for the thinning of the tufts,


Convallaria Japonica is certainly a very rustic plant variety which, for this reason, lives very well in full soil even without the need for continuous fertilization since it finds the necessary elements directly from the soil that hosts it. In other circumstances, however, proper fertilization is essential, which can be divided into various phases. In spring, between April and May, a granular fertilizer specifically designed for flowering plants should be administered. At the end of the autumn season, however, it is better to integrate the soil with a soil improver that reinforces the plant in view of the cold winter. Immediately after flowering it would be important to administer a phosphorus-based fertilizer, an indispensable element for the plant at this particular time of year.

Convallaria japonica: Exposure and diseases

The Convallaria Japonica, as happens for any type of Convallaria, prefers the location in particularly shady areas. It is no coincidence, in fact, that it grows very well under trees of considerable size and which certainly create a not indifferent shade. The Convallaria Japonica, however, does not suffer particularly if placed even in sunny areas, as long as the heat conditions are not excessively exasperated. In very hot areas, therefore, it is better to provide a position sheltered from the sun’s rays during the hottest hours. Diseases and parasites in general infest the Convallaria Japonica very rarely. The only annoying animals for this plant are the snails that can feed on its leaves, and which must be eradicated using special snail killers or traps with beer.
