Timing  

Lily of the Valley plants flowers in the summer so you want to time your planting around this. The plant should be in a dormant state, which is why fall is an ideal time.

However, you can get away with planting in the spring, especially if you are transplanting established flowers. Lily of the Valley starts as bulbs, or rhizomes, which then go into the ground.

These underground tubers will spread out and while the plant will be dormant over winter, it will erupt into growth in the spring before blooming in the summer.  

The perfect place  

Unlike other flowers, Lily of the Valley actually prefers full shade. If you need to, partial shade is ok, and while the flower may be ok in full sun, it’s best to keep it cool.

One thing to really keep in mind is that Lily of the Valley can spread quickly. In fact, if left on its own, it can actually take over most of your garden.

Unless you want this to happen, you should only plant Lily of the Valley in a closed-off section of your garden, or even in a container. This way the roots can’t grow un-impeded.  

Soil  

One great benefit of Lily of the Valley is that it is fairly versatile. While it does prefer soil that drains well, it is quite hardy and you can plant it in a number of soil conditions, and don’t have to worry about the pH level.

You may be tempted to add fertilizer to the soil but Lily of the Valley doesn’t actually need any. As long as your soil isn’t terrible, you don’t need to add anything to it.  

Dig the hole  

The hole for your Lily of the Valley plants does not need to be deep as the soil only has to lightly cover the bulb. So, once you have your plant bulbs, simply dig a hole that is as deep as it is.

Place the bulbs, or rhizomes, in the hole. If you want to increase the rate of moisture intake, you can snip off the edge of a rhizome.

Cover the rhizome with soil so that it is just barely covered. Then, give the area a good watering.

If you want to plant more than one Lily of the Valley, spread them out by 4 inches. Remember that the plants will quickly spread out so you don’t need to plant too many rhizomes.  

How to Water Lily of the Valley  

Lily of the Valley prefers moist soil when growing. However, like most plants, you don’t want the soil to be soggy, or else the roots can rot and die.

Planting your Lily of the Valley in a shaded area means the soil shouldn’t dry out too easily, so you won’t have to water too much. If the temperature rises and it isn’t raining a lot, you should then hand water your plant to ensure the soil remains moist.

Division  

Lily of the Valley is a prolific grower, sometimes too much for its own good. If you let it be, the plant will take over as much space as possible.

Obviously, this might not be ideal for most gardens. The good news is that Lily of the Valley is easy to divide.

Even if you have room for this plant, you might still want to divide it periodically. If you notice the flowering is less robust as your plant ages, this is a sign it’s time to divide.

Wait until the plant is dormant, in either spring or fall. Under the ground, you will find a network of bulbs and roots, called rhizomes.

Dig up these rhizomes and then separate them out. You can then plant these rhizomes in other parts of your garden, in containers, or gift them to neighbors.

Plant the rhizomes in the soil as if they were new plants. Give them a good watering and they should take hold fairly soon.  

Leave the foliage  

After your Lily of the Valley blooms, you may be tempted to clean the plant up. However, while you can remove the spent blooms, you should keep the foliage in place.

This foliage will keep producing energy through photosynthesis, which is then stored in the bulb underground. The more foliage there is, the healthier your plant will be the following year.  

Add compost  

Lily of the Valley can live for a very long time. And, while it doesn’t need a lot of help, you can still add a bit of compost to keep it going.

Once a year, in the spring, add compost to the area around your Lily of the Valley. Gently dig it in around the plant but be aware of the network of rhizomes underneath.

You can also add a layer of bark mulch around the plant. This will prevent weeds from growing as well as keep the soil moist, which the plant loves.
