Garden Cleanup - It’s never too early to begin!

Fall Garden Cleanup

•Work while the weather is pleasant

Some of us who have seen a few more winters, appreciate warmer soil under the knees or the opportunity to spread chores out over a longer period of time. On the home farm, we do not generally clean up the garden until after our fall bulb harvest and shipment is completed in early November, but we do start by cutting back any lily stem that has completely browned by early September. When lily leaves have turned from green to at least yellow-green over most of the stem, you can safely cut them back to just above ground level. Do not pull stems out of bulbs as you risk doing serious damage to the bulb. Until stems are fully brown and crispy, there is enough moisture in stems to tear tissues within bulb centers, opening up the possibility of rot over winter.

• Reduce the possibility of spreading fungus spores

Some areas of the US have been very wet and cool this spring and summer (us included) and the pesky fungus Botrytis has been a concern for more than one gardener this year. Any stems/leaves/flowers that show tell tale brown spots should not be tossed into the compost this year, but rather sent to the trash. Fungus spores typically are not damaged by the low heat of compost piles and could still be active should you spread the finished product in your garden. Fungus spores tend to live on top of the surface over winter, so it is a good idea to clean leaves from not only lilies, but also roses and peonies at summer’s end.

• Removal of spent blooms helps bulbs to grow larger next season

In commercial production, the bulbs are planted in long rows. The last 3 feet of each variety is allowed to open flowers for photos and to check the planting stake is correct, then the flowers are removed to encourage the largest growth possible for the season. Everything a lily bulb needs for flowering in a given year is already present, and as the stem elongates, the scales that make up a bulb are slowly depleted. Once flowering is completed, your lily begins the task of rebuilding itself for next year’s growth, the reason why you do not want to allow seed pods to develop (which saps strength) or cut off too many green leaves needed for photosynthesis.

Bob personally checks all our lilies at least once a week during the summer and rogues out any, which may have accidentally been mixed into the row during planting. Not only does he compare photos, but he also looks at the growth habit of individual stems, looking for anyone “out of place” in the row. Most lilies we sell are kept down for three or four years before they are sold, so any less than perfect stems/bulbs are removed before harvest.

• Freshens the appearance of your garden

Simply removing faded flowers once a week can lift spirits and improve the look of your garden with very little time or effort. Cutting off the top of each stem, leaving all leaves below where the bottom flowers helps to camouflage maturing stems very neatly and directs attention to other shrubs and perennials nearby. Again, when the leaves have lost their green color, you can safely cut them back to the ground.
