During the cold season, gloxinias need a lot of attention. Because only those who hibernate them properly will enjoy the plants for a long time.
Gloxinias (Sinningia) are cultivated as houseplants and delight in the flower window with abundant bloom. The garden gloxie in the flower bed performs the same task. So that you can enjoy your plants for a long time, you have to hibernate them properly. This is the only way they won't break in the cold season. We have listed here for you how to proceed correctly during wintering.
Hibernate gloxinias in indoor culture
From September onwards, the abundant flowering will be over. The plants are then often disposed of lightly. It is quite possible to hibernate the plants and bring them back to flowering successfully next year. Because it is in the nature of the plant to withdraw into the tuber after the flowering phase. The leaves gradually turn yellow and the leaves die off. However, this is not a concern, but a completely natural process.
At this point, you should leave the bulb in the plant pot. The leaves should then die off as quickly as possible. This is important for the flowering next year. The plant should therefore no longer receive any nutrients when the leaves begin to wither. The tubers then only dry and dark overwintered at temperatures around 15 degrees.
The tubers of young plants in particular tend to dry out and should also be watered weekly in winter. For older plants, it is enough to give them some water every 14 days so that the tuber does not dry out completely.
❍ The wintering of the Zimmer gloxinia in brief:
- The plant retreats to its tuber from September
- Remove dried plant parts
- Reduce pouring slowly
- Stop pouring after yellowing
- Overwinter the tuber dry and dark at around 15 degrees
- water occasionally so that the tuber does not dry out
Hibernate garden gloxinia properly
The garden gloxie is quite robust. It is therefore possible to leave the bulbs in the ground. You only need to cover the ground with leaves, brushwood or compost. If the soil is light and permeable, the garden gloxinias spend the winter outdoors without any problems. With heavy soils, however, there is a risk of waterlogging. So there is less risk that the garden gloxia freezes in the bed. If the plants do not form new shoots in spring, it is more likely that waterlogging has formed in the soil and the gloxinium in the soil has rotted.
If you want to dig out the tubers in winter, you do this in a similar way to what is common with dahlias. The tubers are first removed from the ground and then left to dry in the fresh air for a few days. The tubers are then packed on straw in boxes or crates and hibernated dry, dark and cool.
❍ The wintering of the garden gloxie in brief:
Light and loose soils:
- Bulbs can be left in the ground
- Cover the ground with leaves, brushwood or compost as frost protection
Heavy floors prone to waterlogging:
- Dig up tubers
- leave to dry in the fresh air for a few days
- bed on straw
- hibernate cool and dry in boxes or boxes
What happens after winter?
Gloxinias in indoor culture:
In spring it is time to get the tubers out of the winter quarters. Houseplants are now a good opportunity to be repotted. To do this, remove the tuber from the planter and largely remove the old substrate. Then choose a slightly larger plant pot so that the roots can spread well. However, the plant pot should not be too big, because too large pots encourage the gloxinia to expand its roots. However, this is often at the expense of flower formation.
If the root system has not completely penetrated the soil, you can use the old planter again. In any case, you must completely replace the earth. So the plant is again supplied with sufficient nutrients. Then put the planter back in the old place and slowly get used to the warmer temperatures. Now you can slowly start watering again and administer a liquid fertilizer for flowering plants (e.g. available from Amazon) during flowering.
If you have left the bulb in the ground, the first shoot tips should appear in spring. If this does not happen, there is a suspicion that the tuber has roted in a soil that is too wet and heavy. This can be checked by digging out the tuber and examining it. It can often be helpful to place the tubers in fresh, well drained and dry soil.
Bulbs overwintered in the house can be released from the winter quarters in late winter. Put the plant pots in the warm and give the plants a growth advantage. Then it has already sprouted and may already have buds if you plant the gloxinia in the field in May.
Wintering of the gloxinia: advantages and disadvantages
If the plants are overwintered, with a little luck they will sprout again in spring. So you don't have to buy new flowering plants. In addition, the tubers hardly need any additional care during the cold season and only need to be watered occasionally.
First of all, you need to find a cool, dry and dark location for the tubers. Furthermore, overwintering is often not worthwhile for small plants, as the tubers dry out quickly or rot. If you overwinter the tubers outdoors, there is also a risk of the tubers rot- ing due to contact with waterlogging.
