Raised beds and drainage. Keeping the soil hydrated...
Comments (6)...but I do not have any in the rows since I do not want to rot the herbs and carrots. If mulched properly, you won't. I did dig down a few inches tonight and my soil is very moist, so thankfully that is the case. Then don't over water which is what I suspect you may be doing more than you think. And your statement is proof positive that just because it appears dry on tip doesn't mean it's dry underneath. Watering too frequently and too heavily is actually harder on plants than too little water. Roots require oxygen just as much as they require water and nutrients. You will have to adjust throughout the season and be attentive to the amount of rainfall you receive each week. There are two schools of thought on watering. Frequent shallow waterings or less frequent long, deep waterings. The general rule of thumb is that mature plants need 1-2 inches of rain per week in summer. You should provide whatever portion of this moisture is lacking. One inch of rain equals 65 gallons per 100 square feet of garden space. But this is just a guide. Time of the season, stage of the plants, soil composition, and many other factors affect the amount of water required. Be consistent during fruit production. If the plants are young or new transplants, they need time (2-3 weeks) to develop an established root system depending on the plant. Mulched beds require far less water than plants that are not mulched. Raised beds require more than non-raised beds. If a good amount of compost is incorporated into the soil, less water is needed. Compost holds 6-30 times it's weight in water. Dry winds dehydrate plants. Cooler temps require less water. Those using drip irrigation whether from a soaker hose or milk jug are likely getting the best use of their water which is going right where it needs to go and the ground has time to absorb it. There are hundreds of methods of watering. Whatever you do, just be consistent. Roots require oxygen equally as much as they require nutrients and water. I personally believe in a couple of deep waterings per week with the use of 2 inches of mulch to reduce evaporation and maintain a more stable soil temperature....See Moreneed help with building a raised bed
Comments (14)Hey Tammy - well we finally (on June 7!!!!) got all our plants in the pots on our deck! We just had to draw a line in the "frost" and take the chances that the weather was going to improve. Overnight lows have been +2C to -3C and my back has been killing me lugging around heavy terracotta pots full of "stuff!" I finally introduced some mini roses, herbs, and gerbera daisies into my greenhouse, as well...I relocated my greenhouse last year to a shadier spot at the bottom of my garden - with the temp now balanced better, I can introduce more things. I had it in full sun in the previous years and it was a struggle to keep the temp below 35C - nothing lived!!! I also started some sweet peas, freesia (I try every year), and evening primrose - so we will see what happens! If we have an Indian Summer, my growing season (in the greenhouse) can be extended into mid-October. While it is a bit late to start some seeds and bulbs, I always remain hopeful (and am occasionally rewarded with success). I will be working on my raised beds this weekend, and will be introducing some perennials (Golden Creeping Jenny, various thymes, etc) to give some colour amongst the roses and ninebarks - all 38 of my roses survived their wintering, but I may have to replace a few that went a little wild near the end of last summer (some stalks had thorns that would have rivalled medieval war clubs!). Now that I am finally getting into the spirit of things this season, I will be updating photos (on my blog and uploading some here) - I will gladly share photos and exploits with you! Your raised bed looks great - and I love hostas, astilbe, coneflowers, clematis...sounds lovely! This weekend I will perhaps be buying a clematis or two - perhaps a honeysuckle and virginia creeper to grow up and over a pergola I built last year - so many things, so little growing season!!! : ) I may even be brave and try some coral bells this year! There are so many beautiful types (see link to a nursery that shows many examples). http://www.daytonnursery.com/Encyclopedia/Perennials/Heuchera.htm You might have more success than I because your zone is a little more forgiving!! More later, Tammy! Take care... Stuart......See MoreStagnant clay soil, poor drainage question
Comments (7)Hi Y'all, Clay, hmmm, imagine finding clay in Edmond, Oklahoma. I thought ALL the clay in Oklahoma was here at my house. :) It seems like you face dual issues: soil improvement and drainage, although they are related. DRAINAGE: Do you know how quickly that stagnant clay does or does not drain? Does it hold water for days? Weeks? Does it EVER dry out completely? And how far down is the sopping wet soil? If it is just a few inches down, say 4" or 6", I don't think I'd try raising veggies there without a raised bed. On the other hand, if it is 18" or 24" down, you can probably amend the upper layers of clay enough to raise veggies without building a raised bed. And, no, excavating the clay and dumping good topsoil into the "hole" left behind isn't really a great ideal. When you do that, you are essentially raising a garden in a non-draining "container" full of soil, 'cause that clay is going to hold the water and keep your topsoil wet for a long, long time. It is better to keep the clay you have and amend it. Clay is very fertile and rich in minerals. It makes great soil once amended. And earthworms love it once it has organic material in it for them to munch on. SOIL IMPROVEMENT: If you buy a load of topsoil, be careful. A lot of people sell junk clay and junk sand that aren't good for anything and call them "top soil". I wouldn't buy "topsoil" from anyone who couldn't tell me approximately how much of it was sand, clay, silt, organic material, etc. I have bought a 50/50 mix of native soil/compost (but down in Texas and not here in Oklahoma) and it was incredibly good veggie growing soil. You will have to add lots of organic material the first year: peat moss, compost, manure, finely shredded bark, etc. After that, though, you can maintain the bed by what I call "lasagna mulching"...just add whatever you think the bed needs each year to the top of the bed, cover with something like hay, straw or shredded bark mulch that won't wash away, and let the worms do their thing. Some people add sand to clay, and it is a matter of hot debate on the Soil Forum as to whether or not it is a good idea. I did add some sand to improve drainage, but I wouldn't have added a little sand had I not added a LOT of organic material. RAISED BEDS: I prefer them, especially for tomato plants. However, if you add 6 or 8" of organic material to the area where your mom wants to have her herbs and veggies, you will find that all the material HAS raised the level of the soil above the existing grade and you've basically created a raised bed, although I guess it is really just a mounded bed. And there is nothing wrong with that. BTW, I prefer the "lasagna garden" method for building raised beds too. I wish Pat Lanza had written her 2 books a couple of decades ago before I spent all those years double-digging and amending soil at my previous home. Finally, if all your mom wants is a small number of tomato and pepper plants, there is always the option of raising them in large containers, and putting clay-loving herbs in the ground.

Comments (30)Not to sound like an a-hole, but rather to illustrate the practical implications of what I wrote above, this from another thread: In spite of placing the bed on top of good gardening dirt, plants would often only root in the looser soil of the raised bed and not go any deeper. There is a reason for this. It is well known, among many groups of gardeners and farmers (that I pulled out above). What didn't get discussed in-depth upthread due to prolixity avoidance is what I hinted at with the tree planting hole point. I recommend reading the entire comment.
