Garden Sanitation

After cold temperatures set in, most gardeners are nestled in their warm homes thumbing  through gardening magazines and dreaming of next years’ garden.  If good sanitation is not done this fall, the nasty’s that are left in the garden may come back to wreak havoc next planting season.  Pull on the thermals and get your garden in tip top condition by giving it a good cleaning .

When I say the nasty’s I am talking about plant diseases, like potato late blight, which can threaten crops next year.  This disease overwinters in the live tissue of potato tubers and infested potatoes left in the soil, covered with snow, are protected from the freezing temperatures that would normally kill it.  Make sure all potatoes are dug up.  Diseased material should be disposed of but not placed in the compost pile.  Compost piles act as insulators during cold weather and throwing diseased material into it will cause contamination.  Early next spring check the area for volunteer potato plants and dispose of them.  It is recommended to buy clean, certified seed potatoes, rather than planting potatoes saved for seed.

Late blight is spread through the air and from plant to plant under favorable weather  conditions.  It can affect tomato plants and the same sanitation rules apply-clean it up to prevent problems.  Clean up any dropped tomatoes.  Not only are they a potential harbor for disease but if left in the garden, all those little tomato seeds will sprout next spring causing you to have to pull them all out.

Some insects hide under debris such as boards or bricks left in the garden or surrounding area.  Eliminate such debris that might provide shelter from the weather.

The same kind of “clean up” applies to an orchard.  Remove fallen leaves and fruits at the end of the season.  A clean orchard floor is an excellent way to prevent future problems.

Another thing to keep in mind is the possibility of disease carry-over from garden to  garden.  Let’s say you lend a helping hand in Madge’s garden for the afternoon and you use some of your own garden tools.  Soil borne diseases can be transferred between gardens if contaminated soil is left on your tools.  As a preventative measure clean your tools as you use them.   When trimming your woody plants clean your loppers and pruners with isopropyl alcohol after every use to prevent the transfer of pathogens from a sick plant to a healthy one.

Use the gardens down time to research and maybe reconsider the plants you have used in the past.  Many vegetables and flowers offer disease resistant varieties that will stear clear of some of the more common problems.

Preventing a disease before it becomes a problem is easier that trying to get rid of it.  If in doubt, throw it out!

As always, Happy Gardening!
