Drought!

20 years ago

A friend forwarded this post to me.

Friends:


The American Horticultural Society (AHS) issued a significant drought advisory yesterday for our region. This is the *first* time they have ever issued a significant advisory at this time of year (September/October) for our region. This time of year is a bad time for drought, because plants need to store up energy now to make it through the coming winter, and they need water now to do that. We're about 7 inches short of rain the past two months (we've had barely an inch of rain in the last 8 weeks). I've excerpted the following 10-step action plan from the AHS.


Prioritize your watering as follows:


1) New plantings  anything you've established, transplanted, or divided in your garden in the last 12 months is particularly susceptible in this drought; water these plantings thoroughly once-a-week.

2) Don't *feed* any of your plants right now with soil additives  plants need water to process soil additives (like Espoma's

"Hollytone" or "Miracle Grow". Adding these products to your soil right now will just add stress to already weakened and water-starved plants. ((Note from Eric  you really shouldn't be using these products anyway, regardless of growing conditions.))

3) Broadleaf evergreens  they are desperately in need of water right now; give a once-a-week deep soaking ((Note from Eric: at least I or 2 minutes at the base of the plant with hose turned full-on  larger, older plants will need a bit more water)) until the drought ends. These are Rhododendrons, Laurels, Azaleas, Camellias, Hollies (English and American), Arborvitae, Leyland Cypress, Leucothoes, and broadleaf ground covers like Pachysandra. If their leaves are curling, water them twice a week until leaves unfurl.

4) Broadleaf deciduous trees and shrubs - if they are already turning color and dropping leaves, it's probably because of the drought. Water once-a-week; pay particular attention to the shallow-rooted trees like Maple (American and Japanese), Willow, Clump Birch, and Witch Hazel.

5) Narrow-leaf and needle evergreens - don't overlook these  they can tolerate drought better than broadleaf evergreen plants, but they don't "show" signs of drought sometimes until it's too late  these are Yews, Pines, Boxwoods (American, English, Korean) Spruces, Cedars, Tiny-Leaf Hollies, Cryptomeria, Etc. ((Note from Eric  I just lost a dwarf pine and a tiny-leaf holly in the last two weeks - by the time they outwardly showed signs of stress from drought (yellowing/browning), it was already too late for me to save them, so do take heed.))

6) Don't bother watering the earlier season perennials (like Daylilies or Hostas) - they are already naturally going dormant at this time. Most fall blooming perennials (like Asters and Mums) are fairly drought tolerant.

7) Don't bother watering the lawn - it's okay for it to turn brown; it will green up again, although perhaps not until next spring.

8) Don't bother watering your annuals - frost will kill them off in the next few weeks anyway.

9) Don't rake away your fallen leaves - just run over them repeatedly with the lawnmower and mulch them into the lawn; this will help feed your lawn, help to keep your lawn from drying out, and will help it to winter over more successfully. Leave the leaves in your flower beds; they help keep the soil underneath moist, so let them gradually decompose in place over the winter and do not remove them next spring.

10) Finally, don't plant anything new right now - October is usually the best time to plant new shrubs, but not this year, it's just too dry.

    Thanks for the tips. I hope no watering bans are enacted. I'm worried about all the trees not just mine.

    Thanks for the information. I've been wondering what to do with my dry garden. Think I'll send it on to my neighbors and friends in the mid-Atlantic region. Happy

    Thanks for posting this information. We've had so little rain locally (southwest of Richmond) that our dogwoods are dieing. I've lost one in the yard, one other looks very bad (we're watering that one,) and those in the edges of the woods are dieing. My brother in King William said his are dieing, too. (Dead trees have brown leaves just hanging on them. If the leaves have fallen then there's a good chance they will survive.) These are not new plantings but established trees. And the oaks are in real distress around here, too, but there's really nothing we can do about them, just too much water required to keep them alive. The lawn is toast! Most yards here are brown, brown, brown! Only those with very good irrigation systems look decent. I only hope it is dormant and not dead but I've never seen mine look this bad before.

    Most counties around Richmond are on voluntary water restrictions but if we miss the rain predicted late this week that may become mandatory. Several years of drought followed by two years of too much rain followed by drought again... a sure recipe for trouble.

    "anything you've established, transplanted, or divided in your garden in the last 12 months"

    That seems to apply to just about every thing in my garden!

    A holly that I planted last fall died recently. It seemed to be doing fine all winter, spring and early summer. Some leaves started to brown and then it went down hill fast. I guess I did not water it enough. It was in an area with a lot of competition from trees. Also the drought seems to have done in an established pine tree...Scots Pine I think. It was not that healthy of a tree but the stress seemed to put it over the edge and turned it into food for borers. The thread linked below has some pictures of my ailing Scots Pine.

    I see plantings of Viburnums along the road side that look to be on their last leg and many trees are looking very stressed. I am pretty sure that large areas of my lawn are dead. Yep, it has sure been dry.

    "Finally, don't plant anything new right now"

    Opps! I just planted a few shrubs and trees last weekend. How is a gardener supposed to resist?!?

    There *is* something you can do - put the plug in the tub and use graywater from showers and baths, assuming your family is basically healthy. (Just don't put it on things that MUST have acid soil or else.) I've been lugging buckets of water out to my big oak for 3 or 4 weeks now, and also dousing my Japanese cherry and its underplantings. If you don't have a good back, don't do it - I use cat litter buckets, and carrying two at once, I'm lifting about 45 pounds at once.

    However ...
    10) Finally, don't plant anything new right now - October is usually the best time to plant new shrubs, but not this year, it's just too dry.

    So where does this leave something like the exchange? I'm loath to even try to dig stuff when the ground is baked hard, and if it has only a poor chance of survival over the winter with all this stress ...? Right now I'm considering bringing only items that are already in pots and needing to be gotten out of my yard.

    Thanks Anne!

    I'm in central Maryland and my dogwoods and viburnums are looking pretty rough at the moment. This spring I planted 5 blueberries, several evergreens and a large ash tree. I have other plants still in pots. I've kept them watered by using gal size containers, milk/juice whatever works. I poke a tiny hole with a straight pin, sometimes more than one...and I place them around the plants. It can be a lot of work, especially if you have a lot to water. Having a helper makes it go a lot faster. Everything I planted this spring looks great. Once when I took my recycle to the collection center I snagged a bunch of milk jugs. (I came home with more recycling than I took.)

    BTW, it's drizzling here now and there's rain in the forecast for tomorrow but I doubt it'll amount to much.

    Good luck to all~

    Rain oh the glorious rain. I can't tell you how happy I am.
    I hope it continues.

    It's been so long that I've forgotten how to drive in the rain. Didn't even remember the wipers for about 5 minutes, puzzling over how I'm supposed to see through all that.

    The weather people are talking about lots and lots of rain and flooding. I think they said 1-2" East and South of DC, 2" in DC, 2-3" in the Western 'burbs, and more as you go further towards the mountains, with spots here and there getting 6-8" of rain. This is so timely; I was starting to wonder how I'd ever dig anything out for the fall swap.

    Have to admit I have started small patches of new lawn in the last few weeks, and planted a couple of things the other day. So do as the AHS says,not as I do!

    But now it is pouring!!! Yippee!

    is there any thing special I need to do for my curly willows. They are newly planted and despite me watering (apparently not enough) they have lost all of their leaves! The trucks are still green?

    *sigh*

    Eureka! The rains have nourished the earth and it was a good soaking rain. Thank goodness, I was getting tired of lugging all those gal containers.

    I recommend the following web pages for drought information and forecasts. The forecast page is especially useful for gardeners because it gives the outlook for the season ahead. For example, the forecast for the mid-Atlantic region was changed for the better on Oct. 6 (solid green on map = previous drought condition improving or ending).

    G'Day!
    We finally got some rain too! About 2". All summer, i have been thinking. "Thank goodness for soaker hoses!" If i knew who invented them, i would send a thank-you card.

    i think most of the plants i put in after the Spring Swap will make it. The only ones that none survived are the the birch and Carolina Allspice. Half the azaleas didn't make it - but half did. Same with asters and mums.

    Garden looks pretty ratty just now - no second strawberry crop this year - so i'm glad to have those cosmos in.

    Harvested a record crop of basil; made over a dozen quarts of pesto. i think my mum is coming down from NH to swap half of that for blueberry jam.

    Guess she's got some rain now too.

    Happy gardening,

    Man, you should see the bar graph on the Washington Times' weather page! It shows the normal/actual amounts of rain for the past 3-4 months. Obviously, the acutal amount shown in Sept was really short, but this month? Wow! That bar looks like a skyscraper!

    Yeah, today's the 21st, and it's kinda raining, but we're well over the rainfall amount for this month now anyway. It's feast or famine....
