A Beginner’s Guide To 13 Types of Daffodils

At the end of summer, daffodils are rarely top-of-mind. But this is precisely the time when you should be ordering them. And this is especially true for the more sought-after, unusual varieties. Why stick with yellow trumpets when daffodils come in so many other colors, shapes and sizes? See below if one or more of these different types of daffodils wouldn’t be the perfect fit for your 2021 spring garden. Continue reading

When To Cut Back Daffodil Foliage

I know you don’t want to, but you must. You must wait to cut back your daffodil foliage until it yellows. Removing leaves prematurely may neaten things up, but come spring you’ll have far fewer flowers. And everyone knows daffodils look best in big numbers. Continue reading

Daffodil Bulb Care: The Top 5 Things You Need To Know

Recently my email box has been overflowing with questions from readers worried about the unusually warm winter we’ve been experiencing. Many of the questions center on daffodils, in particular, what to do with unruly bulbs. In replying, I first spoke with a few of my local nursery experts to gain their opinion. Following are five of my readers’ top concerns about daffodil bulbs and what to do about them. Continue reading

Spring-Flowering Bulbs: 10 Great Varieties

Spring bulbs in a formal garden setting

Yesterday I supervised the planting of two thousand spring-flowering bulbs. We laid them individually in patterns and dug them one-by-one into the earth. When we were finished, we dressed the bulbs with mulch and stepped back to admire our handiwork. You could almost feel the energy emanating from all those future flowers tucked so snugly underground.

What To Do If Your Spring Bulbs Come Up Too Early

(Last week it was 70 degrees, now it’s 20)

Let’s face it. It’s hard not to stress when your daffodils start popping up mid-winter. As weather becomes more unpredictable, early growth is becoming more and more common in spring bulbs. Not to worry, though. Your plants have seen it all before. Moreover, they’re built to handle a few temperature swings.

THE UNDERGROUND WORLD OF BULBS

To understand why spring bulbs can weather a little premature growth, it helps to take a peek underground.

Botanically speaking, a bulb is a short stem surrounded by fleshy leaves that store food during dormancy. As soon as you plant it in the fall, a spring bulb starts growing.

Each bulb has five major parts:  a basal plate, scale leaves, protective tunic, a flowering shoot and lateral buds. The action begins in the basal plate. During the winter months, roots emerge from this modified stem to penetrate the soil.

As they develop, the roots absorb water and other nutrients that they store in the scale leaves.

In some flower species like alliums, a thin papery covering called the tunic keeps the scales from damage or drying out.

The scale leaves provide food storage, and they also protect the flowering shoot. This vital part of the bulb contains all of the future leaves and flowers. During the winter months, the flowering shoot slowly grows upwards within the bulb, eventually developing into a stem.

Finally, at a pre-determined time in the spring, the leaves break through the soil. Then, approximately one month later, the flowering shoot begins to appear.

At this stage in the process, the key thing to remember is: the flowers develop independently of the leaves. 

This means that even if your bulbs (specifically, leaves) come up early, the flowering shoots still need time (between 5 and 7 weeks) to develop. And before that happens, your bulbs have most likely weathered the warm spell and resumed dormancy.

So if you see leaves poking up out of the ground too early, don’t worry. A cold snap may cause them to yellow and die back, but the bulb will wait things out and send up new growth once things warm back up again.

WAYS TO STOP YOUR BULBS FROM COMING UP TOO EARLY

There are a few strategies, however, that you can implement now to slow things down while providing an extra layer of protection to the flowering shoot.

1. COVER YOUR PLANT

Covering the soil around your spring bulbs will help insulate them against extreme winter weather like frigid temperatures and drying winds. Try mulch, straw, bark chips, leaves or pine needles.

Or, if the plant is budding too early, try draping a cloth over it (securing it above the plant with stakes.) Remove the drape during the day so the foliage can absorb sunlight to warm back up.

2. WATER DURING DRY SPELLS

If there’s been a dry spell for an extended period of time, a little extra water during the day helps bulbs grow. However, make sure your soil has good drainage. Bulbs can rot if they receive too much water.

3.  IF FLOWERS START TO APPEAR

If the weather continues to stay unseasonably warm, your spring bulbs may start to produce flowers. Don’t worry. Even if frost kills off some of the initial buds, it usually won’t affect flowering in the coming months. And it won’t destroy your bulbs. They’ll still flower next year.

4. PLANT BULBS LATE IN THE FALL

The later in the fall you plant, the longer the bulb will take to sprout come spring. Wait until the temperature is cold enough (40°F or below at night) to plant your spring bulbs to ensure they’re fully dormant. Here in Maryland, I plant my daffodils in November.

Finally, make sure to plant your bulbs at three times their height in depth with the base down and the bud up. Planting bulbs too shallow makes them vulnerable to frost heaves and can lead to premature growth. And planting them upside down can stunt their growth.

Author’s note January 2020: According to Science News, there is growing evidence that, in general, warmer springs are bringing earlier spring flowers. This in turn will result in longer growing seasons and drier summers. (This does not, however, mean daffodils in January.) 

Here in Maryland we are having an unseasonably warm winter. In fact, it’s 65 here today on February 3. Below is a photo illustrating the state of my daffodils. (The leaves are about 3″ tall.) I’ll keep you posted as to their development.
