It wasn't until autumn that you put wonderfully plump crocus tubers in the ground. But now it is February and the flowers in purple, white or yellow are missing. What could be the reasons behind this?
Why isn't my crocus blooming?
Crocuses cannot bloom for various reasons, including incorrect planting depth, nutrient-poor or compacted soil, temperatures that are too low, frost damage, rodents or the planting of autumn crocuses. To promote flowering, these factors should be considered and appropriate solutions applied.
How can planting depth prevent crocuses from blooming?
If the crocus tubers were plantedtoo deep in the soil in autumn, the flowers may not appear in spring. The reason behind this is that the tubers are reluctant to push the leaves and flowers more than 10 cm through the soil. In addition, the risk of root rot over the winter is greater this far down in the ground. Therefore, only plant each crocus tuber between 7 and 10 cm deep.
When does the soil stop the crocuses from blooming?
Soil that is toonutrient-poorandcompacted soil can prevent the crocuses from blooming. If the soil is too nutrient-poor, it is recommended to fertilize it, for example with compost (€43.00 on Amazon) or another organic fertilizer.
If the soil is too clayey, compacted and heavy, crocuses will have problems sprouting flowers. Then you should dig up the tubers and plant them in loose, well-drained soil. If the substrate tends to be too wet, waterlogging can occur, which can cause the tuber to rot.
Does too low a temperature stop crocuses from blooming?
In order to produce flowers, crocuses needwarmandbright Sunshine makes the flowers of the early bloomers shine. However, if it is too dark and cold, the crocus flowers will only appear reluctantly or not at their usual flowering time, but rather late.
Did frost freeze the crocus flowers?
The crocus flowers can also freeze due to frostfreeze If the winters are too mild, the flowers emerge prematurely, for example in December. If extreme sub-zero temperatures prevail again, the flowers freeze and do not sprout again at the true flowering time in February/March.
Could animals have stopped the crocus from blooming?
Rodents such as squirrels and voles like to dig up the tubers of early bloomers such as crocuses andprevent the plant from blooming. The animals nibble on the tubers, causing the crocuses to die. Even deer don't like to stop in front of crocuses and feast on their flowers.
Have you planted a different type of crocus?
If you have planted aautumn crocus such as the so-called magnificent crocus or the saffron crocus, you should not be surprised if no flowers appear in spring. The autumn crocus blooms between September and October and not again in spring.
Tip
Be careful when mowing the lawn in spring
If the crocuses are in your lawn and you mowed it in the spring, it may be that you also eliminated the leaves from the crocus. Then the flowering stops due to lack of strength.
