Vine maintenance

Today it seems B... and Curator J... had not planned anything for me to do. So we all scratched our heads, so to speak, for a few minutes while Al and B considered the possibilities. Finally, we decided there are several plants, particularly on the vine bench, in need of cleaning. The scale insects and subsequent black sooty mold collect on the leaves and decrease the plant’s vigor. And, the black curled leaves are unsightly.

I collected three of the vines and brought them outside to the little courtyard next to the workroom. Outside I was able to freely move around the plants scrubbing off the mold and the scale insects. The most affected vine was the Thunbergia mysorensis. The other two vines were Euphorbia heterophylla (Mexican fire plant) and Tetrastigma voinierianum (chestnut vine).

After cleaning, pruning, and repositioning the vines, B mentioned the Zamia plants across from the vines were also heavily infested with scale insects and sooty mold. I spent the last half hour cleaning two of the small plants. But, there are more on the bench in need of cleaning. I will add them to my list for next week.

Meanwhile, spring continues in the greenhouse. These plants are all located close to the vine bench. Two of them are close to my heart:

On the left is Medinilla magnifica from Asia; on the right is Begonia brevirimosa from Malaysia.

Sidenote: B told me that the new student-worker V... had caught a cockroach in the hall. He brought it into the greenhouse and fed it to one of the pitcher plants!

Rebuilding the support for vanilla vines

Raining in February The morning began with a walk in the rain from my car to the Conservatory greenhouses - in the month of February. According to the calendar, we should be in the depths of winter. The precipitation today should be snow not rain. The storm system that we're experiencing is probably related to drenching rains moving inland from the west coast. I met Coordinator A... at the door of the Conservatory. His office desk faces one of the main doors to the building. He cannot escape observing everyone who enters...poor guy, it must be distracting for him. Anyway, as soon as I entered the building we started to discuss his plan for my activity of the morning. He offered me the project of rebuilding the support for vanilla vines which have been suffering from overexposure to sunlight and dry air. A bit of background The vanilla plant (Vanilla planifolia) is in the orchid family. It is native to Central America and Mexico. The seed pods were used by the Aztecs to flavor coc

Frankincense and Myrtle: Fragrant Treasures

If you were raised in the Christian religion, you've probably heard of frankincense and myrrh. But, do you know much about them, beyond being fragrant commodities as precious as gold? Until today, I could not have described frankincense, myrrh, or citronella. But, by the time I was finished with my volunteer shift at the U of M Conservatory greenhouse I knew more about them. However, I will have to wait for another time to actually see a myrrh tree. I'm not sure if the Conservatory has a myrrh tree. I do know myrrh is in the Burseraceae family, the same family as the frankincense tree. They are not in the myrtle family as the name would suggest. The myrtles (or Myrtaceae) are the gum trees of the Australasia, one which gives us citronella (see below). Maintenance of small trees The day's duties assigned to me were to provide general light maintenance to a group of small trees located in the desert and subtropical rooms of the greenhouse. Maintenance included pruning and mak

Infection control in the Conservatory, from mundane to amazing

Volunteering at the University of Minnesota's Conservatory Greenhouse As mentioned in prior blog posts, for the past three years I've been volunteering for a few hours a week at the Conservatory greenhouse at the St. Paul campus of the U of M. This blog is about activities there, and the many fascinating and beautiful plants in the collection. A little background about plant infections Everyone who has cared for a plant, from houseplant lovers to professional nurserymen, has learned the hard lesson that plant pests and diseases are an inescapable fact of life. All plants, domestic or wild, are susceptible to the infectious agents and parasites. Plants in their native habitats are largely protected by the ecosystems surrounding them, where pests do not have the luxury unfettered consumption. Plants grown indoors have been removed from their ecosystem and they are sitting ducks for parasites to proliferate unchecked. Indoor gardens rely entirely on pest control methods with var
