Sometimes, Plant Adoption is the Best Option

By Jane Malec, EMGV

Long before my master gardener journey began, I loved bringing plants into my home. Quite a few years ago while passing by an apartment building at Michigan State University, I saw a dwarf leaf schefflera (Brassia actinophyllia) sitting on the front stoop.  There was a note attached reading “please give me a good home!” So, what was I to do? I officially adopted my first houseplant out of which grew a long habit of picking up plants and bringing them home. Some were gifts, others found like the first one and some were purchased with lunch money during lean years!

To this day, I always have plants in my home. I believe they make rooms more interesting by bringing in life and color. Foliage is the primary draw for most indoor plants I purchase. Unusual texture, shape or color starts my imagination working. Hmm … where could I put this little beauty? So, it stands to reason that while shopping at a favorite garden center a few years ago, a little Philodendron bipinnatifidum, or tree philodendron, caught my eye. It was no more than two feet tall and the foliage was very interesting.  I knew I had the perfect place for this tropical beauty.

 

 

Tropical landscape plants

Philodenron bipinnatifidum is in the Aracea family and is native to Brazil. It grows naturally in hardiness zones 10-12 especially along the edges of rivers in the tropical rain forests and in other areas such as Paraguay. It can also be found in the landscape of more tropical areas of the United States particularly in Florida were many landscape architects feature it in their designs. They are also popular indoor plants both in homes and commercial buildings.

The tree philodendron has a single and unbranched four-inch diameter trunk which and can grow up to 10 feet tall when planted in the ground. A plant grown in a container will  achieve a height usually less than six feet, directly correlated to the container size.  The foliage is unusual with its dark green and shiny leaves.  They can get really enormous growing up to 30 inches or more.  The dark green shiny leaves are enormous — growing to 30 inches or more. Each half of the leaf has eight to ten lobes each of which each can be 20 or more inches in length.  The leaves grow at the ends of the plant’s slowly elongating trunks and are held up on long petioles.  This feature also seems to be fascinating to golden retrievers!

Another interesting characteristic of this plant is the long dangling roots that grow up and out of the soil. They become more noticeable as the plant matures and may not even be present when you purchase a young plant. In fact, I didn’t notice them in my plant until I had it several years and it had grown at least a foot. Growing up to eight feet, these aerial roots anchor to the bark of tree philodendrons growing outside and will provide some light anchorage for the plant. There will still be roots in a container habitat but they will wind through the stems creating a spaghetti look which is really eye catching.

 

This philodendron will flower growing in a container but the plant needs to be 15 to 20 years old before it comes into heat. It is a beautiful petal-less flower which only lasts about two hours. Although it seems like a short life span, it would be amazing to see this unique flower.

Most pests and diseases tend to be caused by an overcrowded environment and/or over-watering. It prefers bright light but will tolerate lower light during winter periods. Also, as a container plant, it thrives outside during our Durham summers and it isn’t particularly fussy about humidity. I had my plant in quite a number of locations over the last few years. It wasn’t until recently that I situated it in a very sunny room of our home. Wow! It took off! The leaves started growing so fast that I could have sworn it was noticeable over night. I had to move all the other plants out of the area to give it room and, of course, it kept growing.

A New Home

About this time, I noticed that my church had a tree philodendron growing in nearly the exact conditions as mine and it was much larger! This wasn’t a good sign for what was ahead for my little kitchen corner. What to do?

For the answer I circled back to the beginning of my journey as a gardener of houseplants. I needed to find this plant a new home. Another bright yet empty corner in the church revealed itself. So, I convinced the church’s plant crew to adopt my tree philodendron and now I can visit whenever I want.  I love happy endings!

Beware of Potentially Harmful Additives in Glyphosate Spray

poison-ivy
Glyphosate spray can help control poison Ivy, but beware of sprays with additives like diquat.

Glyphosate (sold under the trade name Roundup) is one of the most effective, widely used, and safest herbicides in the U.S.

But beware—always read the label. Ready-to-use herbicide formulations of glyphosate often contain diquat, a quick acting nonselective herbicide that may be harmful or fatal to humans if swallowed, inhaled, or absorbed through the skin. Skin absorption is particularly dangerous. In animal testing, prolonged exposure to diquat was shown to cause cataracts. It can also poison some species of fish and harm waterfowl.

The theory behind adding diquat to glyphosate is that it “makes the glyphosate work faster.” Ironically, a 2008 Study in Weed Technology showed that while the glyphosate-diquat formulation appeared to more quickly injure greenhouse plants, glyphosate alone had better long-term plant growth suppression.

I think I will stick with good old glyphosate—it’s been around since 1974.

That said, all herbicides carry risks—some studies have linked prolonged glyphosate exposure to non-Hodgkin lymphoma. Always read the label instructions and use herbicides with care. I use them only as a last resort. Avoid windy days, wear skin protection, goggles, a safety mask, and foot covering. And be careful with pets—they shouldn’t walk in any herbicide that hasn’t fully dried. Exposure to wet glyphosate can cause pets to drool, vomit, have diarrhea, lose their appetite, and seem sleepy.

It’s cold now, but gardeners will be battling weeds again before we know it!

To Do in February

by Gary Crispell, EMGV

It’s February!! Those of us who are die-hard just-can’t-help-ourselves gardeners are

bluebird and box

nearly beside ourselves—right? I mean, we can do stuff! We can dig in the dirt (well, at least the dirt that isn’t moisture-saturated or frozen)! YEA!! Besides, it is almost March when we really get to do stuff. In addition to breaking out the shovels, rakes and hoes the chem-heads out there can start spraying and fertilizing. So, here goes. A prelude to Spring in the key of D# major.

Lawn Care
Cool season grasses (i.e. fescue and bluegrass) should be fertilized with a slow-release fertilizer following the recommendation of your SOIL TEST.

Late February/early March is the best time to apply a pre-emergent crabgrass preventer. There are several easy to use granular products on the market. Be sure to read and follow the directions on the label for safe and proper handling and application. Calibrate your spreader to ensure accurate application amounts; Too little will not give you effective control and too much may damage the turf.

Fertilizing
See Lawn Care above and Planting below.

Planting
And so it begins: The vegetable garden. The reason for some gardeners’ existence, for frozen fingers in February, summer sunburn and the endless supply of liniment in the medicine cabinet.

It is time for root vegetables and salad (and beef Bourguignon—which you can’t grow in the garden).  Plants that can go in the ground in February include cabbage, carrots, leaf lettuce, onions, potatoes, radishes, rutabagas, spinach and turnips. Work a little fertilizer into the soil that was tested in October (while it was still free to do so) following the recommendations of said SOIL TEST.

Be cognizant of soil moisture levels. It appears that Mother Nature is going to maintain that for now, but she can be really fickle.

Pruning
If you have been ignoring previous posts, now would be a good time to prune bunch grapes and fruit trees. Also due for judicious trimming are summer flowering shrubs and small trees.  That list includes Rose of Sharon (Hibiscus seriatcus) crape myrtle (Lagerstroemia species), butterfly bush (Buddleia davidii), and hydrangeas that bloom on new wood (Hydrangea arborescens & H. paniculata).

While you’re out there, whack back the ornamental grasses, too. The new blades haven’t emerged yet and the plants are looking a bit tired anyway.

Got some overgrown shrubs that you’ve been meaning to (or reluctant to) prune heavily? Go for it now.  I understand that if you’ve never done it before it can be a bit intimidating, trust me. The plant will almost always not only survive, but thrive. I am aware of the never-more-than-a-third rule, but sometimes that is not enough. If it needs to go back to 12”-18” … go for it.  Chances are, you and the plant will be glad you did.

Spraying
The orchard needs attention. Peaches and nectarines should be sprayed with a fungicide to prevent leaf curl. Spraying a dormant oil on the fruit trees will help control several insects later in the year.

Other fun stuff to do outside in February
– Perennials can be divided if the soil ever gets dry enough.

– Many landscape plants can be propagated via hardwood cuttings this time of the year.  Some of the plants in the category are crape myrtle (Lagerstroemia sps), flowering quince (Chaenomoles sps), junipers (Juniperus sps), spiraea (Spiraea sps) and weigelia (Weigelia sps).

– Bluebirds will be most appreciative of a thorough house cleaning before the spring nesting season. Remove all the old nesting materials and let them start afresh. It’s like clean linens for them.

Oh, yeah. Lest we forget … order flowers or other living things from the plant kingdom for your significant other. Just for the record, guys like flowers and plants, too. Happy Valentine’s Day y’all! Think positive thoughts about an early Spring and no late freezes.

Ten Lessons Learned

By Kathryn Hamilton EMGV

As master gardeners, we learn things. But we don’t learn everything, and because we are human, we often forget what we learn or think we are so smart that we are smarter than what we learned. I find each growing season to be a lesson in humility, but also an opportunity to learn … sometimes it’s something I knew, sometimes it’s relearning what I’ve learned. Here are 10 things I’ve learned or relearned in 2018.

  1. You can start tomatoes too early. Last year, I started my tomato seeds on Christmas day. In a sense it was a gift to myself, but I was also determined to have the biggest, strongest tomatoes to put into my garden in May. Although I planted, and transplanted, and have a south-facing location for them, I got leggy tomatoes that didn’t necessarily grow into the big, bad boys I’d hoped for, and I didn’t really get a jump on the season.
  2. Take the time to keep track of what you’ve planted. Last year, I planted two different kinds of cucumbers. General Lee, which is recommended for the South, and Tokiwa, “Tokyo Green” which was researched by a friend of mine. By the time I had gotten my “started-too-early” plants to the garden, I’d lost the markers and decided I’d be able to tell which cuke was which. Fat chance. Too bad, because one of them produced fantastic, sweet cucumbers well into August. I’ll have to try again this year.
  3. Plants need water to thrive. My first home had a well, which continues to make me inordinately careful about how much water I use, even though today I have city water. Someplace in the middle of last summer I realized I could capture the condensation from my air conditioning unit which gave me 10 “free” gallons of water a day. (Rain water collection is not permitted here.) After watering my rose bushes, my trees, my hydrangeas, and cleaning my patio, I began to toss the excess water onto my gardenias. Although they had been planted in the right location in terms of sunlight and we had quite a bit of rain, in three years, they hadn’t really blossomed, and I didn’t have the time to figure out why. Suddenly with regular water, I had flowers. Said a friend: “They were using whatever water they had to survive, they didn’t have enough to bloom.” And he wasn’t a master gardener.
  4. It’s not necessarily wise to be greedy. I had

    four beautiful heads of red sail lettuce and refused to pick the outer leaves in quest of the biggest head I could grow. In the end all four matured at the same time and were on the verge of bolting. Yes, I had some heads to share with my neighbors, but I also missed those fresh leaves every day and was forced into several days of red leaf lettuce salad. Not necessarily a bad thing … but I could have enjoyed it all season

  5. Know when it’s time to “fold ‘em.” A plant that’s at the end of its life and is literally hanging on by a few thready stems isn’t going to produce any good fruit. Doesn’t matter that there’s an heirloom tomato “on the vine.” Still not going to taste very good.  I had a similar story with eggplants. Rather than pick them mid-sized, I pushed them to the max and had seeds.
  6. DO NOT over-plant your tomatoes. I know VERY experienced gardeners who still do this. The tomatoes will compete for food, water, and air. You are not likely to have a bumper crop.
  7. Plant your spinach in a hurricane. Spinach is one of those crops that has thwarted me at every turn. No matter what I do, I can’t get this vegetable to start from seeds. This past summer out of desperation, I threw a bunch of seeds into a planter during the hurricane. Within a handful of days (poor record-keeping again), I had spinach. At first I thought it was the wet, wet, wet conditions. But other spinach seeds sown under the same wet conditions went nowhere. I haven’t done a full set of experiments on this, but I’m thinking it’s a combination of wet and warm that helps the seeds jump start. The conundrum around starting spinach seeds in the summer is that they like cool growing weather. I’m sure we ate the spinach that sprouted … but then again, no records.
  8. Start your lettuce on sponges under lights.

    Cutting the sponges into smaller sections allows you to start a variety of seeds in a small space. Growing here: Two romaines and a red. Photo: Kathryn Hamilton

     

    Starting lettuce from seeds has been another stumbling block for me. One day I decided to experiment by growing them on a sponge. I put the soaked sponge in a cleaned out (10% Clorox solution) plastic domed container (you can often get them when you buy cooked chicken at the super market but be SURE to sanitize them). Under grow lights (no heat on the bottom), I’ve seen the lettuce sprout in 2 – 3 days, compared to “never” before. This lettuce is nine days old. I also buy new sponges whenever I grow lettuce. If they are thick I cut them in half lengthwise so they are not so deep. If I’m planting several varieties at once, I cut the sponges into little cubes, one for each variety. A friend, who is not a master gardener but owns a garden shop, says he mixes his seed with packaged cow manure and broadcasts it. In addition to providing nutrition, he says the cow manure also holds moisture.

  9. Pay attention to soil temperature. Even if against all conventional wisdom, you start seedlings like peas indoors, without the right soil temperature they will struggle at est. (And don’t forget to water.)
  10. If you get into a battle of wills with Mother Nature, she will likely win. I have a history of trying to grow things in the wrong spot … simply because I wanted to them to go there. Of course, I had minimal luck at best. How rewarding to know that the gardener’s mantra: “the right plant for the right spot” can be a very rewarding rule of thumb. (And don’t forget to water.)

This winter, take time to reflect on your last year of gardening and consider what changes you can make as you begin anew in 2019. Happy New Year!
