Ideal for gardeners and flower-farmers alike, Pre-Cooled Professor Rontgen Tulip Bulbs are ideal for bringing a burst of bold color to your yard. Their tall, thick stems support jumbo-sized blooms, featuring a blend of unforgettable orange, apricot, yellow and green colors featuring lightly feathered petals. Perfect for spring blooms, these bulbs are an excellent choice for both enjoyment in the landscape and as a cut flower.
Quantity: Each order contains 20 pre-cooled bulbs.
Packaging: Carefully packed in breathable and reusable cloth bags.
Sourcing: Sourced from the Netherlands.
Shipping Restrictions: Ships within the United States only.
In The Garden: With a shovel, dig out a hole about 6-12 inches deep. You can also use a bulb planter, but this can be very tedious if you have more than one or two dozen bulbs to plant. Tulips can be planted very close together, about an inch apart, pointed side up, nestled like eggs in a carton. In the garden, it’s nice to see clusters of tulips all together for the most dramatic impact. We recommend groupings of 10 to 20 bulbs planted in a circular shape or cluster. Once you have placed the bulbs in your planting hole, cover them with the soil you removed and some aged compost if desired.
In A Trench: Flower farmers or cutting garden enthusiasts growing tulips for cut flower production may want to plant using the trench method. Dig out a 3- to 4-foot-wide trench to a depth of 6 inches in your native soil. Set aside the soil you removed to cover the tulips after planting. Place the bulbs in the trench pointed side up, like eggs in a carton, about 1 inch apart. Fill the trench with bulbs and cover it with the native soil you removed.
In A Raised Bed or Pot: Similar to the other planting methods, remove the soil from the bed or pot to a depth of about 6-12 inches. Place the tulips pointed side up like eggs in a carton, one inch apart. Cover them with the removed soil or new potting soil.
Final Steps: Regardless of your planting method, after the bulbs are planted and covered, water them deeply. Continue to water weekly or bi-weekly if it does not rain.

Tulips are spring-flowering bulbs that need a prolonged period of cold temperature to grow and bloom properly. In most of the United States, this cold period is provided naturally by a winter spent planted outside in the ground. However, bulbs planted in warmer regions of the country in growing zones 11-7b including the Deep South, the desert Southwest, and most of California do not get the cold temperature they need because the outdoor ambient temperature and soil temperatures in the winter are warmer than what the tulip bulb requires for proper bud and flower development.
To reach their proper flowering development in warmer regions, they must be given time pre-cooling at (34-45 degrees F) for 6 to 12 weeks before planting. Bulbs that don’t get sufficient cooling will have stunted growth, shorter stems and deformed flowers. We’ve done that pre-cooling for you here on our farm in our temperature and humidity controlled coolers ensure optimum health and viability of the bulb.
Our bulbs have received the minimum amount of chill time for successful flower development. It's best to plant immediately upon receipt of your order to ensure bulb viability however if you need to store them to plant at a later date, you can place in a cool, dark well ventilated location (34-50 degrees F) for an additional few weeks. We recommend planting no later than January 1st.
Don't live in a warm growing zone? You can still purchase bulbs from us too! As long as your ground isn't frozen you can plant our pre-cooled bulbs.

SHIPPING: Our 2024 Pre-Cooled Tulip Bulb Collection pre-orders will ship the week of November 25, 2024. Please note that your order may leave our farm any day from Monday to Friday that week, so your bulbs could arrive the following week, especially if you choose ground shipping or live on the East Coast. You will receive an email notification with tracking information when your order ships. We recommend planting your bulbs upon arrival, so please ensure you have time to plant in late November and December, as we cannot hold orders for shipping at a later date. Shipping fees are calculated at checkout; preview your shipping cost by visiting your shopping cart after adding items. Due to restrictions on the export of plant materials, we do not ship tulip bulbs outside of the United States.
You can order other products like fertilizer, shovels, gopher baskets, and more with your tulip bulb order. Keep in mind that if other products are purchased along with your tulip bulb order, ALL items will ship together with your tulip bulbs this fall. If you would like items to ship separately to receive them sooner, you will need to place a separate order for any items you wish to receive immediately and not with your tulip bulbs.
