Rodd's Seeds of Wisdom Horticultural tips and tricks from Rodd Moesel

Spring grows ever closer and there are an increasing number of things we can do in the yard as the temperatures march upward.

If you want to control crabgrass, goatheads, sandburs, and other summer weeds you should apply a pre-emergent weed killer right away to your lawn areas.  We have been warmer than normal and many trees, grasses and even weeds are budding or germinating a couple of weeks earlier than normal.  You need to apply and water in your pre-emergent herbicide soon, but for sure in the next couple of weeks, to make sure it is an active prophylactic ready to kill your crabgrass and weed seeds as they germinate.  Visit with your local nurseryman for help in selecting the right pre-emergent for your lawn grass and the weeds you want to control.  You can apply the pre-emergent alone or in combination with a lawn fertilizer as a weed and feed type product.

We can now plant virtually all of the cool season vegetable crops.  Most of these crops will do better, the quicker they are planted, to allow a full crop before our summer heat arrives.  It is best to have these planted by St. Patrick’s Day, March 17.  Cool season veggies would include plants of cabbage, broccoli, cauliflower and  onions, onion sets, and seed potatoes.  Early veggie planting could include seeds of beets, carrots, swiss chard, Kohlrabi, the many varieties and colors of leaf and head lettuce, peas, radish, turnips and spinach.  It is a great time to select and plant crowns of asparagus and rhubarb.  Even though some days feel warm, like spring, it is still to early to plant warm season outdoor veggies like tomatoes and peppers as our last average freeze date is around April 7.

There is increasing interest in home grown berries and fruit trees as more people discover the many health benefits of fresh fruit and berries.  Now is the time to plant bareroot strawberries, grapes, blackberries, raspberries, gooseberries and blueberries as well as fruit trees.   If you want to plant the less expensive bareroot berries and fruit trees you need to visit your local nursery or garden center in the next couple of weeks and select and plant those right away.  Berries and trees are also available growing in containers that you can plant anytime through the spring, summer and fall.

This is the best time to prune your rose bushes and summer flowering shrubs and to prune and shape your hedges and trees.  This will allow the plants to produce new shoots and branches with their spring growth spurt positioned and shaped where you want the plant to grow.  Prune to just above a bud pointing the direction you want the new growth to go, usually out from the center of the bush or tree.  The new growth will almost always sprout from the first bud below the cut, heading in the direction of that bud.  Have fun pruning, feeding and planting and there will be even more we can do in a couple of weeks.

Tomorrow is one of those special days where beautiful flowers and horticulture add to the celebration.  Flowers have played a key role in showing love for centuries.  Beautiful cut or potted flowers are a great way to say “I Love You” to your favorite Valentine.  Whether it is long stem red roses, a pot of blooming tulips or daffodils, a cute African Violet or a mysterious and enchanting orchid or bromeliad let flowers help you express your love and affection on Valentine’s Day and throughout the year.

The days are growing longer and the early signs of spring are all around us as the yellow forsythia flowering shrubs start to bloom. The daffodils have already stretched from the ground and are getting ready to unfurl their yellow trumpet flowers to announce the early arrival of spring.  We are running a couple of weeks early at this point but still have a high risk of hard freezes for about another 8 weeks.  If you want to do some food gardening you can already be planting cool season veggies like seed potatoes, onion plants, onion sets and many of the green leafy crops like cabbage, cauliflower, spinach, swiss chard, kohlrabi and lettuce or root crops like radishes, turnips and carrots.  This is a great time to plant asparagus, rhubarb and horseradish as well as strawberries, blackberries, grapes, gooseberries, raspberries and blueberries.

For those of you that want to control crabgrass, sandburs, summer grasses and broadleaf weeds this is the optimum time to apply the pre-emergent herbicides or weed killers.  You can get these products as a weed killer only or available mixed with lawn fertilizer as a weed and feed type product. For years we have advised to apply these from when the forsythia start to flower to when the Redbuds are done flowering. The forsythia are in bloom and spring is running early so you need to apply these products sooner rather than later as most will only kill the weed seeds as they germinate.  Once weeds have germinated the pre-emergents are not effective except for formulas that contain Dimension or Sulfentrazone that are still effective on some weeds after germination while the weeds are still very young and small.  In a normal year crabgrass and summer weeds will germinate from mid March to early May so applying your pre-emergents from now until mid March will allow the products to provide the most effective “birth control” for crabgrass and weeds.

Look for a herbicide or weed and feed product that contains prodiamine (Barricade), Dimension, Team, Balan or Treflan to give you good control of crabgrass and most weeds in your lawns.  Versions of the Dimension, Treflan and Gallery can even be applied to ornamental flowerbeds and container gardens to give pre-emergent weed control in those areas.  Remember to read and follow the directions and not to use a herbicide any place you plan to plant new seeds for at least the next 6 to 8 weeks.  Visit with your local nurseryman for help in picking out the right pre-emergent for your lawn and flowerbeds.

We have been blessed with great winter weather, however, with shorter days and cooler temperatures most all of us spend more time inside.  The cabin fever and longing for spring seems to grow in each of us, as this winter season stretches out.

Houseplants can lift our spirits, give us hope for spring,  and add fresh oxygen to our enclosed homes and offices.  House plant sales are always highest during this season when we are “cooped up” inside so much more.  Not only do houseplants add color, life, beauty and interest to our home but numerous studies by NASA and others prove their value in cleaning our air of pollutants while producing the fresh oxygen we mammals require.  Plants and humans as well as other animals were designed to function or work together.  Plants need the carbon dioxide we give off and that can poison us when levels are too high and we need the clean, fresh oxygen that plants produce whether outside or inside.  That oxygen is important outside for our whole biosphere but it may be even more important inside the closed up spaces of our homes, offices and even spaceships.

All plants have this natural ability to filter our air, cleaning up carbon dioxide and other pollutants but studies show some plants are especially effective like chlorophytum or airplane plant, members of the Dracaena family, and spathphyllum or peace plant.  There are hundreds, probably thousands of different plants which can grow well inside.  Their success will vary depending on your light levels, the temperature you maintain, air drafts, humidity levels and your watering habits.  The early plants grown inside by our grandparents were ficus or rubber plants, philodendron ivy, golden pothos ivy,Boston Fern,  and growing out sweet potatoes or avocado pits in the kitchen or bathroom window.

Today, there are many new selections of ficus, dracaena, philodendron, and pothos that make very successful houseplants.  For very low light you can use the traditional Sansevaria or snake plant, Aglaonema (Chinese Evergreen), or Aspidistra  (Cast Iron plant).  When placed in better light the spathphyllum will periodically produce white “flag” type flowers to add a beautiful contrast to their bright green shiny foliage.  There are several palms that do well indoors including the dwarf Neanthe Bella, Ponytail palms, Rhaphis, Bamboo, and if you have better light Areca and Majesty palms.

Numerous other great house plants include Bromeliads, Crotons, Calathea, Hawaiian Schefflera, Bird of Paradise, selected ferns, Dieffenbachia, Nepthytis, Anthurium and many others.

Remember most all plants will perform better and be healthier with more or better light but many will tolerate and hold up in lower light.  The more light, the more water most plants will need.  Let house plant soil get dry to the touch and then water.  Our home and office heating systems tend to dry out the air, so it is always a good idea to mist the foliage of your houseplants from time to time to raise the humidity around them or you can put the plants on a saucer of gravel filled with water.

Select a few houseplants to add to your space and enjoy the fresh air and beauty they can add to your life.

Welcome to the fresh new year of 2012, just waiting for you to define it and give it character and memories.  This is a special season as we recover from the excitement and intensity of the holidays while getting back in rhythm for a new year.

This is the season when we traditionally reflect on our life, the year gone by and plan or think about the year ahead as we set new goals and plot new directions.  This process of review and planning can also be beneficial when you are thinking about your yard, landscaping, and gardening efforts.  Do you want to create a new flowerbed, do you want to plant more trees or shrubs?  Do you want to add an automatic drip or sprinkler watering system?  Do you want to grow your own fresh vegetables? Do you want to add and landscape a porch, patio or outdoor living area?  Do you want to add a hobby greenhouse?  Do you need to prune and shape your trees and shrubs?  Do you want to add a water garden, a butterfly or wildlife garden?  Do you want to add more garden benches in your yard, start an orchard or vineyard, plant an herb or kitchen garden?  There are so many fun things you can do to improve the appearance and add value to your home or property while getting healthy exercise and enjoying time outside that your yard deserves consideration as you set your goals for the New Year.

We humans are tempted to want to do all these things but if you will focus on a couple of garden or horticultural projects you want to tackle this year, you are more likely to get them accomplished.  Winter weather keeps us inside a lot more and that gives us a little extra time to research your projects in newspaper or magazine stories, in books, seed and garden catalogs, or over the internet.  You can attend classes or workshops at your local OSU County extension office, Oklahoma Horticulture Society or participate in local garden clubs and plant societies.  Don’t forget that one of your best resources is often a good visit with your local nursery or garden center.  Their local knowledge, experience and input can dramatically increase your chances to be successful in your landscaping and gardening efforts.

2011 was one of the most difficult years of my lifetime, for those raising crops or plants.  We had an exceptionally cold winter last year that set all kinds of record lows followed by a summer drought and heat that tested the very will to live of many trees and plants.  Hopefully we got those extreme weather challenges out of the way last year!  We hope and pray that we can all relax and enjoy a more “normal” year ahead and give all our plants from tomatoes to trees a chance to really perform and enrich our life experiences.  We hope that 2012 is your best year yet and produces great satisfaction and happiness as you become more engaged with nature in your very own yard.
