After planting Calla Lilly bulbs in ground how long does it take to sprout? I planted 4 separate bulbs 6 weeks ago (approx. 80 degree weather) and so far no signs of sprouting. I have been watering every day and dahlias planted same time are flourishing.
Your calla lily should be up by now. Were the rhizomes firm and free of soft spots and mold when planted? They can develop rot in soil that is too wet. If you have heavy clay, amend with peat, coarse sand or perlite to improve drainage. Calla are planted shallowly unlike most other bulbs/rhizomes. I would carefully try to dig one up to see what is going on.
