The most cheery and bright blooms that give the first notice of spring’s arrival are the tulips. As spring rolls around, you will first notice green shoots emerging from the soil that later grow to produce showy blooms in different colors. You may be wondering, ‘when to plant tulips in Oregon?’
If you want to incorporate the beauty that comes with tulip blooms into your garden, it is imperative to do proper timing, however.
Knowing when to plant tulip bulbs can make the difference between having a beautiful tulip garden or an open garden with no blooms.
If you wish to add tulips to your flower garden in Oregon but are unsure when to plant them, this article will help you determine the right time to plant and how to do it.
When to plant tulips in Oregon?
For a beautiful Oregon flower garden with tulips blooms in spring, tulip bulbs are best planted in fall, particularly when the soil temperature drops below 50 degrees Fahrenheit.
The main reason why tulips are planted in fall or winter is to give them adequate time to establish and harden in the cold soil condition.
To be precise, plant tulip bulbs in late September, October, or early November, depending on your USDA gardening zone. Oregon is in USDA zones 4b to 7b. Plant tulips bulbs within 6 to 8 weeks before a hard ground freezing frost.
At this time, the soil is still workable, so tilling and planting won’t be a challenging task. Always check on your presumed average frost dates to be sure of the correct planting dates.
Generally, the overall planting rule is to plant tulips when the night temperatures are between 40 to 50 degrees Fahrenheit. For the colder zones, bulbs are planted in September through October, while for the warmer zones, the bulbs can be planted until late November.
Notably, the fall of the first frost doesn’t automatically mean that planting time is over. Tulips are not like seeds that will fail to germinate due to extreme cold conditions. You can still take chances and plant in winter as long as the soil is workable.
When the soil is still warm, do not plant tulip bulbs too early because they will presume the condition to be spring and start sprouting or even produce short blooms that will eventually be killed by frost. Planting late in the winter is also discouraged as it enhances the rotting of the bulbs before they establish roots.
Planting tulips
After noting the right time to plant tulip bulbs, it is also important to know how to plant them. Planting in the right way is also key to having beautiful tulip blooms in your flower garden.
First, you need to identify a planting site that receives at least 6 hours of sunlight every day. Tulips do well in a sunny area which encourages them to produce adequate foliage and showy blooms in early spring through summer. Prepare the planting spot by tilling and removing all the unwanted weeds.
In most cases, bulbs are planted at various depths based on their species. Plant bulbs three times deeper than the length of the bulb, most likely 6 to 8 inches deep.
Make sure the growing tip points upside down for easy sprouting. Space the bulbs to about 4 to 8 inches apart to give each bulb adequate growing space.
After planting, add organic manure to the soil you dig out before filling it in the holes. If possible, excavate the planting bed to the level at which the bulbs should be planted.
Add and amend the soil with phosphorus-based fertilizer to be used by the roots while establishing since phosphorus does not go through the soil, and applying it later after planting may not be of any importance to the bulbs.
Water the bulbs to ensure the ground is moist. When the ground gets adequately frozen, add about three inches of mulch to p bulbs from thawing.
Dust the flower bulbs with sulfur fungicide before planting the bulbs to help curb fungi and pests that may attack the tulips.
Aphids feed on flower buds and destroy the blooms, while slugs damage the emerging tulip shoots. However, when you apply pesticides and fungicides early enough, the bulbs will germinate and grow healthy, producing showy and colorful blooms when spring comes.
