Plant my lily of the valley

Lily of the valley likes cool undergrowth! You can plant it in a pot or even with exposed roots outdoors, but it might come to please you eventually indoors. If outside, choose a semi-shaded to shaded location, in fertile, cool soil rich in humus. Don't bury the roots too deeply, which will them be impenetrable to water, so arrange them horizontally, letting the buds remain higher. Finish with a good watering – that's it! If indoors, you may repot the rhizomes in autumn and keep them for a while in a dark place so they can develop a new system of stems. When the new petals appear, place them in soft light and remember to water regularly — Groww will remind you!

Water my lily of the valley

In any case, don't get the leaves get too wet, favourable conditions for fungus growth. If you plant outside in autumn, there won't be a lack of moisture in the soil, so only water in case of spring dryness during the first year and summer dryness from this point on. If you've planted after winter, keep an eye out for watering during the first couple of months. Indoors, water at least once a week.

Mulch my lily of the valley

A light layer of mulch over the soil with correct drainage will limit evaporation and much of the need for watering. Dead leaves and little broken branches work perfectly! Spread out in November, and resume if necessary in April-May. 3-4 cm of mulch should be enough.
