One of the easiest ways I have found to create holes for plants is to use a battery powered drill with an auger.
I have tried two sizes, a 1.75″ diameter with a short shaft and a 2.5″ diameter with a two foot shaft. The smaller shaft works well if you are sitting down, but does not leave a clean hole. You need to use one hand to clean it out before putting in the plant. The advantage is that the hole is smaller. The drill does have a tendency to get dirty as a result of having a shaft which is so short.
The 2.5″ diameter auger makes a clean hole, but the hole is larger. This is my favorite since it is easier to make a clean hole and easy to just throw in the plant and fill it in.
I have had good luck using an auger in good soil and bad. The auger will break up the soil into small pieces and will make it easy to fill in when the plant is in the hole.
If you have a basement with a south facing wall, then you are in luck. I have a couple of different plants that wouldn’t live if they were just out in the garden alone, but with the extra heat, they can over-winter and come back every year with no work on your part.
Here are a couple of plants which have come back reliably for the last five years.
For schools, try and use a south wall for the garden and put the more tender plants up close to the wall.
With Solidago or Goldenrod you have lots of different choices when you go to the nursery and it’s hard to know which variety to buy. I have bought many, if not all local varieties and most of them look like the type below. I don’t know exactly which species this is, but I do know that the school kids and myself have a lot of work to do. You not only have to dig it out, but also make sure that you don’t leave any runners or pieces of runners in the ground. This is a good reason to be very careful when you buy plants for a school garden. Don’t put in any plant which is aggressive and will take over an area.
Many varieties of solidago in a home garden will take over an area and spread via runners and rhizomes which grow at a prolific pace. If you look at the size of the stalks left behind, these plants get at least five foot tall and many times will flop over. Nothing else has a chance when it has taken over an area.
I have finally found a nice variety that stays in place and looks gorgeous in the fall – Solidago sphacelata – Golden Fleece.
This variety only gets 24 inches tall and grows at a slow pace.
It’s April 21st and in St. Louis we have just been visited by our first Monarch butterfly. This was a female looking for milkweed to lay eggs on.
What is interesting to note is that just six days ago, we had frost yet the cooler temperatures have not hurt the monarchs or the milkweed.
Unless you have started milkweed from seed, most people won’t have any milkweed to provide the visiting monarchs.
Swamp Milkweed is one of my favorites in spring as it has a lovely form and beautiful flowers.
The problem we have is that it only lasts three or so years before it dies off. The problem is probably the hot dry summers we have, which is not conducive to any plant with swamp in it’s name.
To avoid having to buy new plants every year, make sure you collect the seeds when they ripen on the stem, put them in a paper bag and then plant them in late fall where you want them to grow. Next year you will be rewarded with lots of new plants free of any cost. You can also buy seeds online and plant them outside in the fall.
Another trick I have learned is that your can dig up plants early in the spring and divide them. This way you may end up with six plants instead of one.
If anyone suggested putting in a garden in a baseball field, people would think you were nuts. We just had a similar situation where 1700 plants were put in a playground last year and a year later they are almost all dead and gone.
Kids running around in a limited area, playing soccer, tag, etc. are going to run right through the gardens and trample all the plants. That’s what happened in this one school garden. Do the math on buying 1700 plants and the effort involved in planting and you realize how much was wasted on that one garden.
One solution in a limited playground area is to put out a few large pots which are out of the way and can stand up to soccer balls. Large pots do need more frequent watering than plants in the soil.
