Fall is for Planting

Fall will probably always have a hard time competing with spring when it comes to generating gardening enthusiasm. I guess there is some natural rhythm that encourages us to plant in spring.  But fall planting has many benefits.

ü  Soil is warm... warmer than in the spring. Roots continue to grow in the fall well past the time that leaves are shed.

ü  Moisture is usually plentiful and reliable in fall. And, deciduous plants that we establish in fall lose their leaves, reducing demands for moisture. Fall planted trees and shrubs have a ‘leg-up” on the spring planted ones regarding root growth and are better prepared for the likelihood of summer droughts. 

ü  Plants are cheaper! Every garden center I pass has some incentive for fall tree and shrub sales. Take advantage of it. You have nothing to lose and lots to gain. Do check plant quality before buying.

Fall is a perfect time for lawn care.  As a serious Philadelphia Phillies fan I have been listening to one of the major turf product suppliers telling me to “feed and seed” my lawn in almost every radio broadcast since March. Well, as the old saying goes, “Even a stopped clock is right twice a day." That fellow was on target in late spring… and again now.

September might be the ideal month for new lawn seedings but Penn State guidelines say seeding until October 15 is fine and we can stretch this deadline to late October successfully in Southeastern PA . One of the best reasons to establish new lawns in fall is to avoid the competition of summer annual weeds such as crabgrass. Crabgrass germinates and competes with spring seedings but not in the fall. The warm, moist soil is ideal for germination and root growth. Spring is a poor second choice when it comes to lawn establishment. A word of advice: simply tossing grass seed on the soil surface will not result in germination. That seed needs to be in the soil, not on it.   See this Penn State publication for details on renovation seeding.

Weed control and fertilization are two maintenance tasks that are best done in the fall. Weeds translocate herbicides very well as they approach dormancy. This means good weed control because the root systems of perennial weeds are killed. Controlling weeds is the fall means virtually weed-free lawns in spring.   Clover, dandelion and other broadleaves weeds are pretty easy to control with modern chemistries available in the garden center. October is a great month to go at it. Weed and feed products can kill two birds with one stone. But generally, sprayed on herbicides provide better control of broadleaved weeds.

If you have not applied some nitrogen fertilizer this fall, do it ASAP. You’ll be rewarded with good plant response this fall as well as next spring. Fertilization may be the best weed control practice you can perform. Dense turf competes with weed invaders. How much fertilizer should you apply? Label instructions will get you in the ball park. For a more precise approach, you can get a Penn State soil test kit here and follow the recommendations.  Ever applied lime to your lawn? If not, there's a good chance that this cheap pH adjuster will pay off. Soil tests will advise on this, too. If you are guessing… 50 lbs of ground limestone per 1000 square feet is a starting point.

Plant bulbs now. This is certainly a case of practicing delayed gratification. It will be months before you see the fruits of your labor. But, you can’t have that glorious spring display of daffodils and tulips if you aren’t willing to go to work now! Plants lots for best  effect. Think in terms of 25, 50 and 100. 

Not into flowers? How about garlic? October is garlic planting month. I use Columbus Day as a reminder to plant garlic but there is plenty of leeway on this. A local farmers market is a good place to find locally adapted garlic varieties and you can find one by looking at our Fresh From Bucks County Farms Directory.  Growing garlic is very easy. Check out some highlights here in one of my previous blog posts. 

Odds and ends. What better time to be in the garden than on a cool sunny day in fall? Here’s a list of some other tasks suited to the season:           

            Kill perennial weeds. Canada thistle, bindweed, poison ivy. As long as they have green leaves they are great targets for translocated herbicides such as glyphosate (Roundup, etc).  

            Start a compost pile. Tree leaves, brush, garden clean up stuff.. they all make great ingredients for a compost pile. For the basics check out this publication from Illinois Extension. This cool Cornell University video goes into details and this Cornell publication has even more good composting information.

Winterize garden equipment. Why not put all of that summer garden gear to bed in good condition? Clean and sharpen shovels, hoes and other hand equipment. Rub some linseed oil into wooden handles. Service power equipment. Drain and hang hoses. Empty and store flower pots and other containers. 

Seed cover crops into vacant vegetable garden beds. Rye is probably the best all around winter cover for our area. Find it at farm supply stores. Rye can be seeded until the middle of November and makes a dense, winter hardy ground cover. Spade that overwintered rye into the soil in early spring before it gets too tall. You’ll be amazed at the massive root system it creates.

Fall is for Planting… Trees, Shrubs, Bulbs and Vegetables

Yea, I know. I blogged about this last year. But this message is worth repeating because fall is such an outstanding time to plant trees, shrubs, bulbs lawns and, as I wrote in mid August, many vegetable crops, too.

OK, the basics one more time, then some particulars… the reason fall is such a good time to plant: soil temperatures are warm which is good for root growth; air temperatures are cooling and rainfall is usually plentiful which reduces the need to do maintenance irrigation; deciduous plants are dropping leaves but roots remain active long afterwards which allows for establishment; winter dormancy is followed by Spring, another season of cool, moist weather that aids establishment before the stresses of summer; plant material at nursery/garden centers is plentiful and often a bargain as retailers try to shed inventory.

This was such an outstanding year for turfgrass growth that the number of people feeling the need to re-seed is probably lower than normal. However, if you want to re-seed a lawn, Penn State has outlined the steps is this publication. The key is to suppress the weeds, raise the fertility and then seed the correct species by lightly incorporating the seed into the soil. A “slit seeder” available at most good rental places is the ideal tool. It cuts a small groove into the soil and drops seed in one operation.

Penn State has dozens of publications on lawn management that deal with fall lawn care. Besides planting, there are other chores that are best performed in the fall such as broadleaf weed control, liming, fertilizing and aeration. Check it out.

Penn State Master Gardeners will be planting trees in our little Almshouse Arboretum at Neshaminy Manor Center in November. We’re hooked into the Tree Vitalize program that provides” bare root” trees to public areas in an effort to re-vitalize tree cover in Southeastern Pennsylvania. We’ve planted more than fifty trees, both spring and fall, with a one hundred percent success rate. Here’s a link to specifics on tree planting instructions. Buy good quality plants and you, too will have great success.

Finally, back to the vegetable garden. Last night I seeded spinach. I was waiting for soil temperatures to cool down a bit because spinach germination is adversely affected by high soil temperatures (above 85 degrees). Some of that spinach will be harvested this fall. Some of it I’ll allow to overwinter, providing an early harvest next spring.

There are still about 6 weeks until our first frost and we often experience a long warm period of growing weather after that first freeze. That’s what make the fall vegetable garden so nice and productive. The leafy vegetables, root crops and cole (cabbage family) crops all thrive in the cool fall air.

My first broccoli is ready for harvest and a bunch more is on the way. Brussels sprouts buds are beginning to swell, lettuce plantings are up and more are on the way. Broccoli rabe always germinates in about 3 days and I look forward to my own sausage sandwich, South Philly style in a few weeks with that rabe on top.

Fall Flowers

Spring flowers are a nice thing. Maybe seeing bright colors after a drab winter is the reason that spring flowers are so memorable. But right now I am enjoying fall flowers…. Goldenrods (Solidago), Asters (Aster) White-snakeroot (Eupatorium rugosum) and Beggar-ticks (Bidens) are just a few of the beauties that are blooming now. September is a good time to appreciate them. Fall leaf color is not competing for our attention yet.

I had to get out my plant references to identify the White-snakeroot that is blooming (white) along the 611 bypass near Danboro. It wasn’t in “Weeds of the Northeast” so I went to “The Plants of Pennsylvania”. I like “Weeds of the Northeast” because it lists several hundred common weedy plants and has lots of color pictures. “The Plants of Pennsylvania” doesn’t have color pictures but lists several thousand species! It helps to have a rough idea of what you’re looking for when consulting it. So, as I was researching the White-snake root I learned that there are 18 Euparoriums, 45 Asters and 26 Solidagos in Pennsylvania.

Besides the colorful show that fall blooms provide, many of them provide forage for insects, including honey bees. If you are near a bee hive in September, the fragrance of goldenrod and aster nectar is unmistakable.
If you enjoy identifying local flora, the two books I mentioned are excellent references. You can find both of them at on-line book sellers.

Bowman's Hill Wildflower Preserve in Washington Crossing, PA is offering guided wildflower walks this fall, daily at 2 p.m. for a small fee. A great way to learn the names of more fall bloomers.
