Gardening sample collections -

The sample must be collected properly or the resulting report and recommendations will be meaningless. There are no shortcuts, but essentially it boils down to this: pull 10 to 12 soil cores from an area of interest, mix them thoroughly in a plastic bucket, then place about a pint of the mixed soil into a soil sample box to send to the lab.

Again, there are no shortcuts and heeding all of the information that follows is crucial to ensuring that sample collection is not a waste of time. Samples may be collected and submitted any time of year.

However, sampling would be strongly beneficial in the following scenarios. The starting point of sample collection is defining the area of interest.

This will be an area in a yard or garden with uniform soil that is planted or will be planted with same or similar plants e. vegetables, shrubs, or flowers. The area of interest could be as small as a raised bed, or as large as an acre lawn. Regardless of the size of the area, the sampling procedure is the same.

In a typical landscape, a comprehensive sampling plan might involve pulling samples from several different areas. In example below, there are ten areas of interest that might be sampled, as follows:.

The first step is to collect the cores again, 10 to 12 from the area of interest and mix them thoroughly. A core is a slice of soil from the surface to the desired depth. Within the area of interest, the cores should be pulled from random locations.

A good strategy is to zig zag across the area, stopping every few feet to pull a core and drop it in the bucket. Sampling depth depends on the plants growing or to be grown in the area of interest based primarily on the rooting depth. Here are some general guidelines for sampling depth:.

The cores should be well pulverized using a gloved hand is sufficient and mixed thoroughly. Remove roots, rocks, vegetation and any other non-soil debris. The sample about 1 pint is then pulled from the mixed soil.

Choose an identifier that will help you remember the area represented by the sample, such as FLGA1 flower garden number 1 or BBER1 blueberry row number 1. Curation of the Spirit Collection was made possible through a grant from the National Science Foundation NSF DBI Botany Marie Selby Botanical Gardens.

The label is placed in the lower right corner of the sheet. An envelope for small loose parts or seeds may be folded from a quarter sheet of acid-free typing paper and glued anywhere it will fit. We usually use the "glass plate" method of mounting plants. A thin layer of glue is spread on an aluminum cookie sheet traditionally a sheet of glass.

If using white glue, some water can be stirred in to dilute it to the consistency you want. The specimen is first arranged on the paper as it will be glued, and all necessary cleaning and trimming is done. Piece by piece the plant is placed into the glue, making sure all parts have touched down and picked up glue.

It is then lifted and blotted on newspaper, and placed on the paper. A paper towel is gently pressed against all parts of the plant to squeeze out and blot up excess glue and to push the plant against the paper. A thin layer of glue is spread on the back of the label with a palette knife, and the label smoothed into place and blotted.

Another method of gluing is useful for tricky specimens like wispy grasses, which may gloop together in glue or recalcitrant parts such as roots or fuzzy leaves, which often seem glue-repellant.

The specimen is arranged on the paper and held in place with weights. Then, working from the roots upward, the weights are removed and glue painted gently on the under side of the plant with a palette knife, and then blotted.

The weight is then replaced before moving on to another part of the specimen. The weights are removed before placing the specimen for drying. The specimen is covered with a sheet of waxed paper so the glue won't stick to anything else.

A square of cardboard is placed over the label to hold it flat while it dries. Padding may be added to press down the flatter parts of the specimen if there are bulky parts like stems or fruits. A sheet of cardboard may be placed between specimens to distribute the weight.

A board and a weight we use a rock top off the stack. The plants are left to dry overnight. Specimens that are well mounted using archival materials will last essentially forever, but only if protected from "agents of destruction" such as molds, light, and insects. They should be stored in a tightly-sealed box or cabinet.

No pesticides need be used if no insects can get into this space. Insects can be killed by freezing the specimens after the plants are dried, but either before or after mounting at a temperature of ° F. for three days or longer, preferably in a freezer that is not self-defrosting since these have cycles of warm temperatures.

Specimens should be placed in a plastic bag first, and left in the bag until they reach room temperature after coming out of the freezer. Everything should be frozen before being placed in your storage space, and if an infestation is found, everything should be removed and frozen, and the space thoroughly cleaned before replacing the specimens.

The specimens of Calochortus albus pictured at left were collected in The same techniques we use in the museum can be used for projects like decorated notecards and framed arrangements of flowers and leaves. Such projects typically use separate small flowers and leaves, which are easier to press and dry than bulky scientific specimens are.

They may be successfully dried between the pages of an old phone book. Press them inside a fold of paper as described earlier, so that you have a way to handle the flowers after they are dry. You can lay dozens of small flowers or leaves on a page.
