Planting Guides

Planting Tips for Zinnia grandiflora

These plants won’t begin to grow until warm summer weather has arrived. The long thin string-like roots are brittle and do not like to be disturbed when transplanting, so don’t scratch out the root ball. When transplanting while it is still cold, water the plant thoroughly only once. Continued watering during cold weather will rot the roots. Don’t start to water regularly until the weather warms and the plants begin to grow.

Comments about High Country Gardens Zinnia grandiflora:

I had high hopes for this plant but it arrived dormant and never grew. Perhaps it will show up next spring?

      Comments about High Country Gardens Zinnia grandiflora:

      Unfortunately, this Zinnia did not make it out of the gate. I was perplexed why it did not survive the initial season of planting. We did have a wet spring and early summer that year, so possibly that was the problem.

      Q & A

      USDA Hardiness Planting Zones

      To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

      • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
      • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
