Rolly pollies

220px Armadillidium vulgare 001 Rolly polliesRolly pollies look like a miniature armadillo that rolls up into a ball when disturbed. The scientific name of their family is “Armadillidiidae,” for obvious reasons. While often thought of as pests, they are actually rarely harmful to plants. They mainly feed on decaying matter on the soil surface. However on occasion, they feed on young, seedlings. Discourage them by sprinkling washed and crushed eggshells, corn meal or diatomaceous earth around the base of your seedlings.220px Armadillidium vulgare 000 Rolly pollies

People are surprised to learn that rolly pollies are not insects, rather they are crustaceans. They are related to shrimp and crayfish, breathe with gills, and need humidity or moisture to survive.

Biodegradable pots

Peat pots (pots made out of peat moss) are a product that people like because they are told to simply plant the pot with the plant.

In theory, peat pots and other biodegradable pots are a great idea and there are many options similar biodegradable peat pots (pots made out of coconut fiber and even processed cow manure). However, we find that it is a bad idea to simply plop these pots into your garden. The problem is that if the edges of the pot stick up above the soil level and the wind h100 4911 640 300x225 Biodegradable potsits the edge above ground, then it has the potential to  wick all the moisture out from the whole pot and can kill or stresses the plant.

So, if you want to use a peat pot or other biodegradable pot, be sure that just before you set the plant in the soil you rip off the exposed upper edge above the pots soil line so that the edge is even with the soil line in the pot. This will prevent the moisture from wicking out of the pot. Also be sure that none of the pot is exposed to the air after planting.

Often our alkaline soils slows down the ability of the roots to escape through the pot so it helps to poke some holes in the bottom of the pot to insure the roots can escape from the pot into the surrounding soil.

It has fragrant leaves (when brushed against) and it produces sprays of Rock Spirea 1962 Rock Spirea for your xeriscapesmall, white flowers at the ends of arching branches. After the flowers fade, the seeds are also ornamental, producing pinkish seed heads. Rock Spirea does best in full sun to half shade and may decline if watered too much.

Basil likes it warm so wait to set plants out in early June. Regularly pinch the tips to get a bushy plant and always prune flower stalks. Basil is best used fresh as dried basil loses most of its flavor. It can also be frozen for storage.

Time to cut back ornamental grasses

A fast, easy way to cut the ornamental grass is with a small folding pruning saw . Use the cut grass as a mulch on your perennial bed or add to the compost pile. The most dependable ornamental grasses you can grow on the High Plains include Karl Forester (all types), blue oat grass and blue fescue.

Dwarf Iris time

What’s blooming right now in Cheyenne? Dwarf irises!IrisRet2 Dwarf Iris time

These dwarf irises come every year with little care and they each year they come back more plentiful than before. They bloom through the unpredictable weather of spring and do fine in the snow and cold of early to late March. They can be planted in a lawn (even dandelion killer won’t hurt them) or a in bed. These dwarf iris go by the fancy name of “Iris reticulata,” for the bluish/​purple ones and “Iris danfordiae,” for the yellow ones.  They’re among the first to bring color to the garden at the beginning of spring.

They come from small bulbs planted in late summer or early fall and you can often find them sold as a mixture of yellow, blue, dark purple and light blue. Look closely at the bluish shades and you’ll see an intricate little pattern that attracts bees like a lit airplane runway.
