The Ultimate Buying Guide for Grow Bulbs
Grow bulbs are the start of beautiful flowers and plants. Choosing the right ones can make your garden thrive. This guide will help you pick the best bulbs for your needs.
Key Features to Look For
When you buy grow bulbs, check these important things first:
Size and Firmness
- Size Matters: Bigger bulbs usually grow into bigger, stronger plants. For tulips or daffodils, look for large, plump bulbs.
- Feel the Bulb: Good bulbs feel firm and heavy. Soft spots mean the bulb might be rotting inside. Avoid any bulbs that feel squishy.
Appearance and Health
- Skin Intact: The outer papery skin should mostly be covering the bulb. Minor scrapes are okay, but large breaks can let in disease.
- No Mold or Sprouting: Do not buy bulbs covered in white or black mold. Also, bulbs that have already sprouted long green shoots indoors might struggle once planted outside.
Important Materials and Types
Grow bulbs are living things. The material they are made of (which is mostly stored food) determines how well they grow.
Bulb Structure
Most garden bulbs are true bulbs, like onions. They store energy underground. Some popular types include:
- Spring Bloomers: Tulips, daffodils, crocuses. These need a cold period (winter) to bloom.
- Summer Bloomers: Dahlias, gladiolus. These need warmth to grow well.
Packaging Quality
How bulbs are sold affects their quality. Good packaging keeps them dry and cool until you plant them. Bags or boxes that let air circulate are better than tightly sealed plastic if the bulbs are stored long-term.
Factors That Improve or Reduce Quality
The quality of your bloom depends on what happens before you buy them.
Factors That Improve Quality
- Proper Curing: High-quality bulbs are dried (cured) correctly after digging. This prevents rot.
- Right Storage Temperature: Bulbs should be kept cool (but not freezing) before sale. Heat damages the inner structure.
Factors That Reduce Quality
- Damage During Harvest: Bulbs that were roughly dug up might have internal bruises. These bruises can lead to rot later.
- Too Much Moisture: If bulbs sit in wet conditions, they will surely start to rot before you ever plant them.
User Experience and Use Cases
Think about where and when you want flowers. This guides your purchase.
For Beginner Gardeners
Start with easy-to-grow bulbs like daffodils or grape hyacinths. These are very forgiving. They provide a great early spring show without much fuss.
For Container Gardening
If you use pots, choose smaller varieties or mix different bulb heights. Ensure your containers have excellent drainage. Poor drainage is the number one killer of potted bulbs.
For Long-Lasting Color
To enjoy flowers for many weeks, mix early, mid-season, and late-blooming varieties of the same type (like mixing different tulip bloom times).
10 Frequently Asked Questions (FAQ) About Grow Bulbs
Q: When is the best time to plant most spring-blooming bulbs?
A: Plant spring bulbs like tulips and daffodils in the fall, usually between September and November, before the ground freezes hard.
Q: Do I need to fertilize my bulbs when planting?
A: Often, you do not need fertilizer right away. If you use it, choose a low-nitrogen bulb food mixed into the soil below the bulb.
Q: How deep should I plant a bulb?
A: A good rule is to plant the bulb about three times as deep as the bulb is tall. Pointy side up!
Q: What should I do if my bulbs have already started sprouting?
A: You can plant them carefully. Plant them slightly shallower than normal, and make sure they get enough sunlight once they emerge.
Q: Can I leave my bulbs in the ground year after year?
A: Some bulbs, like daffodils and crocuses, return reliably. Others, like tulips, are often treated as annuals and need to be replanted yearly for the best show.
Q: What does “naturalize” mean for bulbs?
A: Naturalizing means the bulbs will multiply and come back stronger each year without you needing to dig them up.
Q: How much sun do most bulbs need?
A: Most spring bulbs need at least six hours of direct sunlight during their growing season to bloom well.
Q: How do I stop squirrels from digging up my bulbs?
A: Plant bulbs in wire mesh cages, or cover the planting area with sharp gravel or cayenne pepper mixed into the soil.
Q: What is the difference between a bulb and a corm?
A: A bulb (like an onion) grows from layers. A corm (like a gladiolus) is a solid, rounded base that stores food.
Q: Should I water the bulbs right after planting?
A: Yes, water them in well after planting. This helps settle the soil around the bulb. After that, winter rain usually handles the watering.
