Do you have plants that need extra water this summer? 
Many of us have a few plants that aren’t connected to an irrigation system. Some people don’t have an irrigation system and use a hose to water plants, which is time-consuming and inefficient.
 
While you can certainly haul out your hose and water each of your thirsty plants, it is not the best way. The main problem is the hose puts out water quickly and the soil can’t absorb it fast enough. As a result, much of the water runs off and doesn’t benefit the plant as much as it should.
So, if the time-consuming task of watering plants by hand isn’t your cup of tea, I’m here for you. You can make life easier by creating your own portable drip irrigation system with a recycled milk jug
This solution is very easy and will have you digging through your recycle bin collecting your used milk jugs.

To get started, you will need an empty plastic milk jug and a nail.

1. Heat the nail using a lighter or stove burner. Then use the nail to pierce 3 – 4 small holes in the bottom of the milk jug.
2. Fill the milk jug up with water, put the cap on and carry it upside down to the plant. Turn it right side up and set it down to the plant that needs irrigation. *You can also set the empty milk jug(s) next to your plants, bring the hose to them and fill with water that way.
3. Slightly loosen the cap, which will allow the water to drip out of the holes at the bottom – this allows the water to penetrate the soil slowly, instead of running off.

Once the water has drained out of the bottom of the jug, pick up your milk jug and move it to the next plant. After you are done, bring the empty jugs inside and store until the next time you need them.

If you live in a windy area and worry the milk jug will blow away, weigh them down with an inch of small rocks in the bottom of the jug – the rocks won’t interfere with the water dripping out.
I usually recommend this method of irrigating cacti monthly in summer.
This portable drip irrigation system is a great aid for those who live in areas that are suffering from drought or where an irrigation system may not exist.
**A semi-permanent variation of this method is to create holes along the sides instead of on the bottom. Then bury the entire jug next to the plant, leaving just the top exposed. To water plants, remove the milk cap and fill with water and replace the cap.

    I was thinking one would have to put stones inside to stop it blowing away but burying it would solve that problem – as well as one of sightliness. However, I suspect those of us plagued with slugs might be giving them a congenial home underneath.

    LOVE this idea! I don't have an irrigation system, and this is a great way to water some of those plants that are further out and don't often see my hose during dry times!

    Hi Noelle, yes we do that here too. We only have dry and wet season, so during the dry we do that for our most cherished plant. When plastics are not yet available, the old people use bamboos with small holes at the bottom and it keeps small seedlings withstand the dry season.

    Love the idea! I might even set up a five gallon bucket in this way. We just returned from our house in Lake Havasu, AZ. I will keep this idea in mind for our next visit. Didn't need it this time around because of the nightly rains.

    Excellent tip. I've done something similar with buckets but milk jugs are MUCH easier to come by and more suitable for smaller plants than 5-gallon buckets. Instead of a heated nail, I use an icepick. But I'm not sure how many people have icepicks anymore :-).

    Have too many jugs to refill by hand (15 or more per row, 5 rows) so I strung a hose with a “T” leading off into each jug much like a used car lot string of lights or banners. problem is first few jugs overflow while last few jugs get little or no water. how can I solve this?
    thank you

    I bury terracotta ollas in these plant beds – easy to fill and totally hidden, except for their tops, so not unsightly.
