Transplanting/caring for young Hepatica seedlings 

We talked about seeds and  Hepatica germination – we need to have patience. Not only the seeds may germinate in the second year after sowing even if they were kept moist, also the seedlings, in most cases, are not very fast to develop.  Some will remain at the cotyledon leaves stage in the first season, others will grow one true leaf. In either case, they can be quite tiny and intimidating.

Let’s see about transplanting.

When to transplant?
One feature of Hepatica is that they put up a good growth in the spring through summer (roots, leaves, seeds, future flower buds) and then they take a ‘break’ until next year. For this reason I like to transplant in early spring or if not, in the fall; at least, the young plants will start the next season already well prepared.

What potting mix to use?
There are various recipes recommended by Hepatica growers. Unfortunately, most are not easy to reproduce exactly here. I’ve tried to mix various products available in the last years and some were better than others. What I want in the end is to have an easy to reproduce recipe using soil brands anyone can buy (in Canada).

I came up with this mix, which I think is pretty good: mix all ingredients in equal parts (1:1:1)
Perlite
Pro-mix potting soil
All-purpose potting mix:  Fafard brand is a good one. Unfortunately this sector of the landscape industry is non-regulated and most brands don’t specify the contents of the potting mix, plus, in almost in all cases they contain too much peat.

As a rule, as long as good drainage is ensured all should be well, so other combinations could be tried.

 Pots

Taller pots are preferable. You can basically use any type/size of pot proportionally sized in regards to the seedlings size and transplant 1-2 seedling/pot.
To avoid handling many individual small pots one can also use a rectangular planter instead. Another option is a compact-tray with a good height.

Transplanting
Remove the seedlings from the sowing pot and carefully separate them. As seen in the pictures, Hepatica seedlings have a fine root system.
Transfer the seedlings in a new pot, add mix and take care to press only around the roots. The watering will settle down the mix well (add more mix if necessary).

Location: same like for adult plants, keep the pots/trays in a location with plenty of sun in the spring and shade starting summer. If necessary cover them with a plastic mesh. Water when necessarily (deep watering and let dry between) if the pots are not exposed to rain; a light fertilizer during the spring growth is beneficial.

Planting in the ground:
Usually in the third year the seedlings  can be planted in the ground.
To continue growing in pots transplant again to a larger size pot/container. Hepatica species are fitted for container growing if you have a small garden, or unsuitable soil conditions. You can easily provide sun in the spring and shade starting summer by moving the container in different spots.

Most often also the first flowers will appear in the third year to reward your efforts!

*I referred in general to Hepatica because in the end there is no difference between various species when it comes to germinating the seeds and transplanting (H. americana, H. acutiloba, H. nobilis, H. japonica and H. henryi).
