heaving ground???? What causes it & what does it cause????

When I planted bulbs in the fall, I eft the ground level. Now it is anything but; I think this is called heaving ground.
I planted these bulbs: daffodil, tulip, hyacinth and crocus. Did I cause it by planting too many bulbs?? Will my bulbs be effected (ie die)??

Does the ground freeze in your area?

Otherwise, it might be the earliest of the bulbs growing, and breaking through the ground, lifting it as they grow.

I don't know if the ground actually freezes. . . air temps get below freezing and it snows occasionally (longest time of snow on the ground was 3-4 days in the last 10 years.)

This area is my layered spring bulb trial, all planned to sprout/bloom sequentially. Right now, crocus, daffodils and one other kind are sprouting - all at once! But not in the entire section or all together...scatterted around.

Moles? Phenom called plowing soaks up moisture, freezes and softens ground, wouldnt explain heaving - try tamping the ground, or researching for air spaces near the bulbs as moles will leave. Also, you may have chipmunks in that area that love to rearrange bulbs, as well.

The word " Heaving" would normally be used for soil movement on a far more (almost industrial type of movement, maybe in farming or new building areas,
When you get frost/freeze, this can lift the soil or when thaw starts, you may see the soil drop slightly, it's perfectly natural however, IF your talking the soil raised by around 5/6 inches, that's the start of soil Heaving.
Yes you get moles causing soil movements BUT these are normally mounds and are little heaps of soil scattered over a wide area. Voles can do the same but on a smaller scale.
As mentioned before, the bulbs also need to move the soil as the bulbs expand from winter sleep, they are growing greenery, flower buds and taking up moisture/food from the soil way under the soil and this all happens usually before we notice any green shoots peeping through the soil.
My own oppinion would be to leave well alone, allow the bulbs to grow on and show off there beauty,UNLESS you notice disease, any other problems with the bulbs.
If the small raised parts in the soil are annoying you, your best bet would be to GENTLY hand fork over the soil taking good care Not to step on any bulbs still hidden UNDER the soil as the don't all peep through at the same time BUT you find they ALl catch up with each other by flowering time.
Hope this helps alleviate some worries for you and you can sit back and enjoy the fruits of your hard work for many years to come.
Kindest Regards.

Gently remove one or two of the heaved bits of soil. See what is under it.

It's been a week or so since I checked this section and noticed the bulging hill. I re-checked todayl and this area is now level again. . . I did nothing, so I won't weorry about the soil haVing a "hiccup". . . LOL

Ghosts!

There truly are times when doing Nothing is the best way to go. Us gardeners kill off more plants through kindness than neglecting them,
best of luck. WeeNel.
