HOW TO SELECT QUALITY FALL-PLANTED BULBS

To get the best results in your garden, always start with premium quality bulbs and plants.

Most people use the general term "bulbs" when referring to true bulbs, corms, rhizomes and tubers. Here's how they are different and how you can recognize quality.

 

TRUE BULBS AND CORMS

Tulips, daffodils and alliums are "true bulbs." Inside the bulb is a basal plate with roots, layers of leaves, and one or more buds. True bulbs are measured in centimeters around the widest part of the bulb. Larger bulbs produce bigger flowers with stronger stems, so a 12cm tulip bulb will give you better results than an 11cm bulb.

Crocus and freesia grow from corms, which are similar to true bulbs, but contain stem tissue rather than leaves. As with true bulbs, corms are measured in circumference, and bigger corms produce the best flowers.

RHIZOMES AND TUBERS

Rhizomes are enlarged stems that grow close to the soil surface. Bearded iris and cannas both grow from rhizomes. Like bulbs and corms, rhizomes contain stored food energy. Large, grade #1 rhizomes are heavier and have more growth points or "eyes" than #2 or #3 rhizomes. 

Tubers are another type of enlarged stem. They are typically graded by weight, with #1 being the heaviest, best quality tuber.

FIRMNESS
Bulbs should be firm to the touch. This tells you they have been properly stored and are in good condition. It is normal for fall bulbs to show some surface mold. This does not affect performance.

If you are purchasing bulbs in a store, press them gently to make sure they are firm and not mushy. When you purchase bulbs from Longfield Gardens, we guarantee they will arrive in excellent condition.
