Drip Irrigation of roses.....

Post by DD » Sat, 21 Feb 2004 09:34:19



        I have a drip irrigation system to water my roses, each rose has two 4
litre/hour drippers. At the moment I am leaving the system running for
an hour in the late evening each day. The ground seems damp enough and
the roses are flourishing but it seems a lot of water for each rose. Can
anyone give me an idea how much water a four year old [or older], bush
rose, would need?
        I live in Sydney [Aust.] and we are in the middle of a severe drought
so any possible savings without compromising the plants is in the
general interest of the community.

Last year I didn't use my drip irrigation at all: here in North
Florida it either doesn't rain for months or it rains to the point
of flooding.  Anyone growing any crop apart from pine trees
for lumber pretty much has to have some sort of irrigation on
standby: either it'll barely be used, or it'll be essential to
keeping the plants able to produce any crop at all.

I found a couple years ago that during a drought, an hour with
one 4 liter/hour dripper daily was about right for my (slightly
younger and smaller than yours, then) bushes, but my soil holds
moisture well even though it's largely sand (the rest is clay,
with pure clay underneath for quite a depth above limestone).
My guess: you're giving them about what they like, but they'd
get by on less: roses are greedy for water and so long as the
drainage is good they'll take whatever you give them.  I'd try
cutting back a little (maybe 45 minutes a day instead) for a
week or so, and seeing how they fare.

Again, this was a couple years ago in Florida, where the air
is rarely dry, and when even during droughts a foggy morning
is likely.  I didn't have mulch either.

Good luck!

It was good to have your confirmation on the amount of water though I
should point out that the weather here at the moment is hot and humid
and has been since December [Blackspot is rampant]. It will likely
continue this way until early March.  I have Lucerne hay mulch round my
roses and the soil is pre***ly clay but it has been tempered by
constant additions of mulch .

Thanks for your answer.............

I use 8 gallons a week per rose.At 1 gallon per hour.
I water more than 1 time a week though. I live in California.

Hoe! That seems excessive.

My drippers are typically set to provide
about 1 Gallon twice a week during a drought.

Water them during the early morning 5:00 AM ish
That way the sun will quickly burn away any moisture
before disease sets in.

Ground should not be 'damp' it should be just moist
to the touch. Cut down on you number of waterings to
2 per week and see how they perform. If they are wilting a
bit and the soil is drying out increase to 3 times a week.

Roses typically are not daily watering plants but like a
heavy soaking 1-2 times a week.
