Hi Trellum, yes it is difficult to get some garden products as well as plants...you can imagine how much harder it was 8 years ago. But i have good news for you! There are many products, plants, & seeds available on
www.mercadolibre.com.mx. That's one of the ways i know that the younger generation is getting involved, because of the demand for more gardening products and plants and seeds is getting the attention of some vendors. I find food quality Diatomaceous Earth there, organic wasp traps (i have an abundance of wasps and just pulled down some nests from the Dalechampia vine the other day so i need to reduce the populations because they are eating all my caterpillars). I found some molasses there for use when highly diluted to amend the soil and add minerals like potassium, calcium, iron, and magnesium. Unfortunately the molasses was not refined and fermented in the bottle which blew up when i opened it and covered me and the utility room with a thick gooey mess

. I had to clean it up in a hurry before the ants found it. So, for now i order organic, unsulphured molasses from the US, but i expect mercadolibre to have some good molasses in the near future. I also found rain barrels there so i can collect water during the rainy season. Colima does not have a water problem, but the world has a water problem and that means a problem for everyone so i am feeling really happy about these additions to my garden. Also, i find mercadolibre an excellent site to do business with, very well run and organized and trustworthy. So there you go, products at your fingertips.
Yes, i agree completely that the older generation (and growing middle class) want to distance themselves from their farming roots and the poverty associated with that lifestyle. This has occurred in many newly industrialized countries, including the US with people born in the early 1900's.
All of the native plants are my favorites and there are too many to mention, but if i had to say or go to jail, i would say Pseudogynoxys chenopodioides (aka Senecio confusus aka Mexican Flame Vine) native to the El Tejin region of Veracruz. Ruellia, Asclepias c., Ixora coccinea, Justicia brandeegeana (Red Shrimp Plant), Cosmos...all of these plants i have a great fondness for.
When i was 10 years old, i remember traveling in the car with my family, and thinking that i would like to retire abroad somewhere to learn another language, another culture, as an adventure to keep my life rich for as long as it lasts. I did not find it odd that i was thinking these thoughts at the time, but looking back on it, i find it extremely odd

. So this was rolling around the back of my mind for many years. I did not know where, some time later i decided it would have to be warm. I did research on a variety of places and for a number of reasons, decided on Mexico. At some point i suggested this to my husband as a courtesy more than any thing else because i knew he would not be suited for this kind of change. At some point later, after both of my parents had passed away, my husband and i had separated, my other relatives were grown and independent, i found myself free and took care of some business, and up and moved to Guadalajara (5years prior to generally accepted retirement age). I was in Guadalajara for 5 years having the rich, lively, and learning experience i anticipated and found many friends there. But Guadalajara is a mile high city and when the sun goes down it is very very cold, after 5 years i moved to Colima and started a garden. It was so much exactly the right decision for me. It has been and remains to be an adventure so full of life experience and learning and miracles. That's kind of a long reply, but it really is the short version. And, what about you? What brings you to Mexico?
