Title: Planting and caring for crocus bulbs correctly
The size of the tuber depends on the size of the plant
The shape of crocus bulbs is reminiscent of kitchen onions. Just like this, the upper end, from which leaves and flowers will later sprout, tapers to a point.
The size of the bulb indicates how big the later plant will be. The bigger the bulb, the bigger the flowers.
Unpack and plant crocus bulbs immediately after purchase
Crocus bulbs do not tolerate long storage well. If you're buying crocuses for the garden, you should unwrap them immediately and get them into the ground within the next three days. Keep the poisonous tubers out of the reach of pets, especially rabbits.
If you want to care for crocuses indoors, immediately plant the bulbs in a suitable soil-filled planter. Keep it dark and cool.
Crocus bulbs from specialist shops are pre-treated and do not necessarily need a cold phase. Nevertheless, you should set up the planter in a cool place and only bring it into the room after it has sprouted.
The best time to plant crocus bulbs
Varieties that bloom in the spring go into the ground in the fall. The flowers develop in the following spring.
Autumn crocuses are planted in August. They grow very quickly and bloom as early as September. The flowering period lasts until October and in good weather even until November.
How to plant the tubers correctly
- Dig a planting hole
- Add some mature compost if necessary
- Place the onion root-side down
- Fill the planting site with soil
- Enter easily
The depth of the planting hole depends on the size of the bulb. It should be no more than twice as deep as the tuber is long.
Do not plant the tubers too deep or too high. If the ground cover is too thick, it will take too long for the soil to warm up and for the bulb to sprout. If the bulb sits too high, the crocus will easily topple over later.
Crocus bulbs do not need to be overwintered indoors
Crocuses are fully hardy. They survive even very low temperatures without freezing to death. Without a longer cold phase, the tubers would hardly or not at all sprout anyway.
tips
A flower bulb planter is very helpful when planting crocus bulbs. The soil is lifted out by means of the tightened lever and poured back into the planting hole when the lever is released. The markings on the edge are practical, with which you can dig out the planting holes at the desired depth.
