Watering is one of the biggest problems for me. My garden, here in Tuscany, Italy, is a 20 minute drive from my home, is without running water or electricity,in the midst of woods, so only new implants recieve artificial irrigation-the rest all have to get by on rainfall.I harvest rain water or else have to bring it in from a fountain in a town . Most roses do splendidly,though only recently have I begun to try floribundas, for example; I have yet to see if these will accept this regime as well as OGRs, climbers,etc manage to do.
This year we've been very lucky here, weather-wise. June was really nice-it rained on a regular basis,and I never had to water at all. But that all stopped recently; it got hot. The last day of rain was June 17th.
Yesterday I went out there with my moisture-measuring meter,and tested the soil around the new implants (about 25 roses and 5 trees, etc). Only 8 registered as being on the dry side-4 of these were trees and a clematis Montana,so I watered these. The rest registered as being damp, and many as actually wet,though as usual the soil surface is hard as a brick and dry-I have a lot of heavy clay, which tends to do this as soon as it gets hot out. I don't know how accurate these moisture meters are, but I must say that the appearance of the plants did tend to confirm what the meter read-i.e., one of the roses that registered as dry had, in fact, dropped many of it's leaves and seemed headed for dormancy. I must emphasize that I do NOT expect or even desire that my plants bloom once the typical Meditteranean summer drought hits-in fact I de-bud all the new implants . I want my plants to root deeply and learn from the start how to resist in drought. Most of these plants had been planted outside last October/November,so they've been in the ground at least 7 months already.
So now I'm wondering how to act. Last year, I did start watering at the beginning of July, even though most of the new implants did register as having damp soil -BUT the weather was vastly different that year. May had been pretty cool and rainy, but June was totally dry and extremely hot. Furthermore,I had put out those plants in mid-to-late December,so it seemed wise to start watering. I am planning to measure the soil moisture again next week,of course, but I'd really like to hear other gardeners' opinions on how they might regulate themselves if they were in my position...
