Every year around this time, people ask me why tulips that have been in the ground for two years look unkempt when they were so pretty and colorful the spring before, why they aren’t naturalizing and blooming like the daffodils, and why despite all the care they received, only a few weak, spindly leaves have emerged from the masses of bulbs. Tulips, however, are native to regions with cold winters.
For bulbs to store enough nutrients to nourish and repair the plant, it must be consistently cold. Here, it is a requirement that cannot be ensured. Therefore, you will be let down if you plant these recently bought winter-conditioned bulbs and count on them to come back every year. For those of us who have been gardening in the Bay Area for some time, providing tulips with the chilly temps they demand is the only way to treat them as the perennial perennials that they are.
Our work entails:
— Remove any spent flowers as they wilt to prevent the bulb from wasting energy on seed production. So that their nutrients can be returned to the bulb for the growth of the following season, allow the stalk and leaves alone to wither naturally.
— After that, take the bulbs in their containers to a storage area or dig up the bulbs (don’t worry too much about their roots). Remove and clean the bulbs after the leaves have become brown and dried, then let them air dry for about a week.
— It has always been difficult to store the dormant bulbs, but a reader provided this helpful advice: Put them in cardboard egg cartons with labels and a few holes poked in them. The bulbs will remain separate and receive enough air as a result of this. After that, store the cartons somewhere dim and dry.
— Start storing the bulbs in a cold place from the beginning of August for three to four months. 40 degrees or so in the refrigerator. Flowers will produce poorly or not at all at higher temps.
— Plant the bulbs with their noses up in rich, sandy soil in a place that receives full sun in the spring in late November or early December. Plant them 8 to 10 inches deep to achieve the coldest winter soil temperatures. When bulbs are planted deeply, they are surrounded by the chilly soil they need to grow strong roots. Additionally, it helps springtime plants produce big blooms. If there isn’t any rain, be sure to water.
When can tulips be planted in California?
The planting zones in California actually span from 5a to 10b, however we’ll divide the state into Northern California and Southern California. Northern California has its first fall frost around the end of November. Southern California can occasionally experience frosty conditions. If you are unable to identify a frost period, pay attention to your local weather and record when it begins to get cooler. Take advantage of your soil thermometer in this situation!
In all of California, chill your tulip bulbs before planting. The cooler soil temperatures in this region can be adapted to by chilling bulbs in the refrigerator. Before planting, bulbs should be chilled in the refrigerator for four to six weeks.
In Northern California, you should ideally plant tulip bulbs between the months of September and December.
Plant bulbs in Southern California between the middle of December and the first few weeks of January.
Which month is ideal for tulip planting?
- Use chicken wire to cover planting holes, a fence, repellant spray, or container gardening to keep animals away.
Is there anything happier than a large tulip field blooming in the spring? The profusion of vibrant blossoms is a sight for sore eyes after a protracted winter of cold and snow. You may build and enjoy a robust tulip show in your own yard with these tactics and pointers.
How to Choose Tulips
Hybrid tulips make up the majority of the tulips you see in landscape plantings, as well as those offered for sale at garden centers and home improvement shops. For the greatest impact, hybrid tulips normally need to be replaced every year. (We’ll cover how to persuade them to return below.) When given the proper growing circumstances, species tulips will return year after year in zones 4 to 7. These have smaller flowers and pointier petals than hybrid tulips, and they are shorter.
Individual tulips don’t flower for very long, especially the hybrids. However, there are types that bloom in the early, mid, and late seasons at various periods. When buying, choose a couple cultivars from each bloom time category for a long-lasting display.
Where to Plant Tulips
For the best show, tulips need full sun, which entails at least six hours every day of bright, direct sunlight. They are also great additions to rock gardens since they favor quick-draining soil.
When to Plant Tulips
Fall is the best time to plant tulip bulbs. Prior to planting, the soil must have cooled from the summer growing season, which could occur in September in cold regions (zones 3 to 5), October in transitional temperatures (zones 6 to 7), and November or December in warm areas (zones 8 to 9). Use a soil thermometer to measure the soil’s temperature, and plant when it reaches 60 degrees F at a depth of 6 inches.
For tulips to bloom, they need to be chilled. Buy pre-cooled bulbs and plant them in December if you intend to grow tulips where the soil temperature won’t fall below 60 degrees for at least 12 weeks.
How to Prepare the Soil for Planting Tulips
Use Miracle-Gro Garden Soil for Flowers to prepare the planting space for tulips by incorporating 3 inches of garden soil into the top 6 to 8 inches of native soil. Tulips will develop a strong root system in the fall thanks to the nutrients provided by the soil, which is necessary for a significant spring bloom. However, to get the best results from your tulips, you must combine the strength of excellent soil with just the appropriate plant food. For details on what and when to feed tulips, see “How to Feed Tulips” below.
How to Plant Tulips
Tulips should be planted in bunches of 10 or more for the best display. The pointed end should be facing up as you plant each bulb 8 inches deep (measure from the bottom of the bulb and add the depth of any mulch on top of the soil in your measurement). It is possible to place bulbs close to one another. Thoroughly water.
How to Grow Tulips in a Pot
In pots, tulips are simple to grow. The bulbs should be buried at least 8 inches deep, much like with in-ground plantings, so measure from the top of the container to a depth of about 9 inches, then fill the pot up to that point with Miracle-Gro Potting Mix. Put the pointy end of the bulbs in the pot (you can pack them tightly together). After thoroughly watering, cover with the potting mix. Move the container to a cool, dry spot that stays at or below 40 degrees Fahrenheit during the winter before the first frost in your area. Bring the container outside to a sunny area when you notice tulips budding. Water the soil there. Once you notice green growth, start watering often.
How to Water Tulips
When you plant tulips, make sure to thoroughly water each planting space. After planting, give the plants one watering each week for the first month. Then, leave them alone until spring. When the leaves come out in the spring, start watering once more.
How to Feed Tulips
Apply Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food in accordance with the instructions on the package once the flowers have faded. In order for the bulb to conserve nutrients for the following growing season, this will aid in promoting leaf growth. Every year in the late fall, feed for the final time (around the same time as you would plant new bulbs).
How to Cut Tulips to Enjoy Indoors
When the buds are still tightly closed, cut tulips. You should be able to identify the hue of the blooms despite the petals’ possible greenish tint. Put inside a spotless vase with room temperature water. Once cut and brought indoors, tulips will continue to “grow” (the stems extend). Simply trim a few inches from the bottom of the stems every few days if they start to get unruly. If you mix Miracle-Gro for Fresh Cut Flowers into the water and replace the water every few days, cut tulips will stay longer (compared to water only).
What to Do After Tulips Bloom
The best tulip flower display will typically occur in gardens in the spring that immediately follows the fall when the bulbs are planted. Once the petals have faded, trim the flower stalk back to the plant’s base to encourage species tulips to return year after year. After the bulbs have gone dormant, cease feeding them as previously mentioned, stop watering them, and trim back the foliage once it has completely turned brown. Simply pluck up the bulbs from hybrid varieties (which are not perennial) and compost them.
How to Protect Tulips from Deer and Other Pests
Preventing deer from eating tulip blooms is the biggest obstacle in tulip gardening, closely followed by preventing chipmunks and squirrels from digging up the bulbs. Planting holes or trenches should have chicken wire surrounding them on all sides to prevent bulbs from being dug up. (If you’re planting large sweeps of bulbs, which is how to get the best show from tulips, this is most useful.)
Deer are another matter. Installing a long (8 feet or more) fence is the greatest approach to keep deer out of the garden, but most people cannot afford to do this. Daffodil and Crown Imperial bulbs are not consumed by deer, so interplanting tulips with these varieties may help deter them. Alternatively, you may try misting a deer repellent on bulb foliage. In light of this, it is preferable to grow tulips in pots on a screened-in porch if deer are a significant issue where you live. This way, the deer can’t access to the flowers.

Tulips can be planted in Northern California, but how?
The largest bulbs (such as tulips or daffodils) should be arranged in a layer at the bottom, facing upward. They should be roughly 2 inches apart. Add 2 inches of potting soil on top. Leave about 2 inches between each bulb when you plant a second layer of hyacinth or allium bulbs.
When ought I to purchase and plant tulips?
Tulips and other spring bulbs already contain an embryonic blossom. Just waiting for this embryo to start growing. Make sure the tulip bulbs you choose are sturdy and plump. Avoid any bulbs that are flimsy, moldy, squishy, or losing their papery cover.
You should wait until mid-autumn to plant your tulip bulbs, which you should buy in late August or early September (late summer/early fall). If you reside in a region with moderate winters, sometimes even early winter (December) works the best.
Tulips are so anxious to expand that they will immediately send their leaves up if you plant them too soon. Only in the cold will this cause them to freeze. Tulip bulbs should be kept in a cool environment and stored in paper bags rather than plastic while you wait to plant them.
Care of Tulips During Storage
Tulips must be handled carefully and stored correctly before being planted. Tulip bulbs should be kept in the crisper drawer of the refrigerator if you have the space.
Keep them separate from apples and other fruit. Apples and bananas release ethylene gas, which speeds up fruit ripening but destroys any bulbs’ bloom buds. Tulip bulbs shouldn’t be placed in the freezer if you don’t have room in the fridge; doing so will destroy them. The tulip bulbs should be kept dry and in a cold, well-ventilated space, such as an unheated garage.
Can bulbs still be planted in Northern California?
Winter bulb planting for later blooms You might think that your days of planting bulbs are finished after the first frost or snowfall. But you can plant bulbs as long as the ground is usable! If you can dig a hole deep enough to plant, you can plant bulbs as late as January.
