First Frost/Freeze of Season Due this Weekend in D.C. Area

Right on time, the first frost/freeze of the season is due this weekend, here in the Magical Mid-Atlantic, specifically Friday night.

With the turning of the seasons comes a list of things to do to put your garden to bed for the winter season so it can rest:

  • Without delay, bring your tender houseplants and tropicals inside. Check for insects and spray accordingly, if you believe in spraying. Once inside, I give them as much light as possible and only water enough to keep them alive. I could care less if they grow over the winter…the only reason I have them inside is to decorate the rooms and keep them alive until I can put them out again the following April. By then, they are beyond ready to go back outside.
  • ***Continue watering, as needed, until you put the hoses away for the winter. Fall can be sunny with very low humidity, and very dry. Please be sure to lay the hose down at the base of the plant—water on a slow trickle—and allow the water to seep in slowly. Larger plants have big, deep rootballs and the water must get into the ground deeply so the plants don’t die. DO NOT depend solely on irrigation systems during the first couple of years—monitor your plants for water. Remember that newly-planted items do not have the means to absorb water from surrounding soil, until they root. The bigger the new plant/transplant, the more water it’s going to need. I cannot stress this enough.
  • Once the hard freezes arrive regularly, be sure to turn off your outdoor spigots from the inside and store your hoses for the winter, out of the harsh weather.
  • Check the batteries in your smoke alarms (the twice yearly time changes are good seasonal reminders). And check your dryer vents, too. You’d be surprised how many people forget to check their dryer vents—they can get clogged and become a very big fire hazard. There are companies out there to clean the vents for you, if you are not into doing it yourself. And don’t forget to clean out your gutters, too.

Other Fall Gardening Notes:

  • It’s a great time to plant new plants and to transplant shrubs that might be in the wrong place. They will spend the winter rooting while the tops of the plants go dormant, and they will be ready to grow in the spring. I think that fall planting is the best-kept secret in the gardening world. There are exceptions: certain plants don’t establish themselves in the fall, for whatever strange reason; and things that are marginally hardy—at the northern limit of their hardiness range where you live–should not be planted in the fall because they might not have time to root well before the cold weather sets in. They have a better chance of surviving the first couple of winters if they are well-rooted.
  • I don’t like to fertilize shrubs in the fall—especially broadleaf evergreens–because it promotes new growth during the remaining warm days of fall—only to be frozen off when the hard freezes come in. It’s best to let your plants go dormant naturally so they can withstand the winter cold more easily, especially if the winter turns out to be severe. It’s a great time to fertilize deciduous (leaf-losing) trees, however, as they go dormant.
  • No major pruning should occur now; new growth should not be promoted due to the coming hard freezes. Plants should be allowed to go dormant. Minor trimming and shaping are fine; just no major pruning unless you absolutely have to do it. A great time to trim evergreens is during the holidays, when you might want to bring in some greens to decorate.
  • Get the weeds out now! They are all setting seeds and those seeds mean many more weeds next year. Save some time, in advance, by weeding now when the weather is nice.
  • Seasonal color—pansies, etc.,—can still go in now. Pansies should make it until spring and should revive after any winter dormancy.

  • Bulbs—this is the time to plant, now until the ground freezes hard. Remember to buy the best quality tulips and hyacinths you can afford…they decline after a few years in our hot, summer soil. Think of tulips as a present to yourself and buy them fresh every year to get the best show. If you love tulips, it’s worth the money. And remember: deer love tulips, but won’t touch daffodils.

Let me know if I can help you with anything this fall. We are winding down our planting season soon, except deciduous and evergreen (not broadleaf) trees. Maintenance, clean-ups, stone work, fencing, lighting, etc., can continue until the weather shuts down the work.

Happy Fall and I’ll have more in my Holiday Newsletter right before Thanksgiving. Hope all of you are well and happy.

All the best,
