Fall Flower Bulb Planting!

Sean MurphyComment

Fall creates a second season of planting for spring blooming bulbs. Planting in the fall allows a jump start to spring growth. The cool weather helps to make a more enjoyable experience for working outside in the garden and requires less watering. The cooler weather allows spring blooming bulbs to winter over, this is important in order for bulbs to provide beautiful spring cheerful blooms.

  • When bulbs arrive. Bulbs should be planted as soon as the ground is cool, when evening temperatures average between  40° to 50 deg; F. You should plant at least 6-8 weeks before the ground freezes. This is most common in cold climates (zones 1-7). You can, if necessary, store bulbs for a month or longer, if you keep them in a cool dry place. Planting fall bulbs in warm climates (zones 8-11) such as Tulips, Daffodils, Crocus, Hyacinths, Grape Hyacinths, Scilla, and Snowdrops, require pre-chilling in order to bloom. To pre-chill, leave bulbs in their bags and place in a refrigerator for 6-10 weeks. Be careful not to store bulbs near fruit, especially apples, all ripening fruit give off ethylene gas. Ethylene gas can damage and or kill the flower inside the bulb. Once bulbs are chilled plant them at the coolest time of the year. Most importantly bulbs won't last till next season, so make sure to plant them.

  • Read the label. Try to keep the label together with the bulbs until planting. Without the label, you can't tell the red tulips from the white ones just by looking at the bulbs.

  • Where to plant. You can plant bulbs just about anywhere in your garden as long as the soil drains well. The Dutch say, "bulbs don't like wet feet." So, avoid areas where water collects, such as the bottom of hills. Bulbs like sun and in many areas the spring garden can be very sunny, since the leaves on the trees are not out yet. So keep in mind when planting in the fall that you can plant in many places for spring blooms.

  • Prepare the planting bed. Dig soil so it's loose and workable. If it's not an established garden bed, chances are the soil could use the addition of some organic matter such as compost or peat moss. These are available at most local garden retailers

How to Plant Bulbs – Step by Step Instructions

Step 1: Loosen soil in the planting bed to a depth of at least 8”. Remove any weeds, rocks or other debris. You can mix in compost, other organic matter or slow releasing fertilizer if your soil lacks nutrients.

Step 2: Depending on the bulb, follow the recommendation on the label for planting depth. As a general rule, plant big bulbs about 8" deep and small bulbs about 5" deep. Set the bulb in the hole pointy side up or the roots down. It's easy to spot the pointy end of a tulip; tougher with a crocus. If you can't figure out the top from the bottom, plant the bulb on its side, in most cases, even if you don't get it right, the flower bulb will still find its way topside.

Step 3: Now that the bulbs are planted, back fill with soil over the hole, lightly compress the soil but do not pack it. Water to stimulate root growth. There is no need to water continuously unless you live in an area with low precipitation in the winter months.
