How to Plant Your Tulip Test Garden 

   
What to Plant
All Journey North Test Gardens are planted with RED EMPEROR tulips. The garden must be planted with new bulbs each year. Red Emperor tulips are an early-blooming variety that can be purchased in your local garden center or through an online source.

When to Plant
Plant before deep frost hardens the ground. As a rule of thumb, tulips should be planted when the soil 7 inches down is 60° F or lower.

When you plant will depend on where you live. Use the USDA Plant Hardiness Zone Map to determine your planting date.

  • Zones 2 and 3: Plant in September
  • Zones 4 and 5: Plant in October
  • Zones 6 and 7: Plant in November
  • Zones 8-11: Plant 1st week of January after pre-chilling bulbs. See instructions.

Where and How to Plant
Because this is an experiment, all gardens must be planted in the same way:

  • Depth and Spacing
    Bury bulbs 7" deep, at least 4" apart, with pointed side up.
  • Exposure
    Plant in an open area to avoid microclimate affects (avoid courtyards, foundations and pavement).

Sites must be selected according to protocol. See criteria in Garden Site Selection Checklist.

Gardening Tips
Plant your tulip bulbs in a common garden bed, or dig individual holes. A garden trowel or a bulb-planting tool is useful for planting bulbs individually.

  • Watering
    Moisture is necessary for root development before winter. If dry weather persists, water thoroughly.

  • Fertilizing
    All bulbs benefit from mixing bone meal with the soil in the planting hole.

  • Predators
    Protect the bulbs from squirrels by securing chicken wire over newly planted gardens. Bent wire hangers will hold the wire at the edges. Deer - and moose - will eat your tulips when they emerge. Protect the growing plants with more chicken wire.

  • Mulch
    You may mulch the garden after the ground freezes. Remove in the spring as bulbs emerge.

Some schoolyards do not have a site that fits the planting protocol. If you plant in a courtyard, near a foundation, etc. you must include this information about your site in your planting, emergence, and bloom reports.
