Although cheap, it's not a throwaway product, but it's also not UV resistant plastic, so do store indoors, out of direct sunlight. Remember plastic will absorb odours and colours over time, so if you're not going to use yours for a while, store it empty. I wouldn't be leaving fertiliser in here long-term - which might not be safe for your plants anyway no matter what you water with - especially DIY and organic mixes (find out how long each type of fertiliser stays fresh once mixed). First, there is no need for hanging baskets and containers to drip after watering: bedding plants performed well when watered little, but daily. It took 160ml (about 6fl oz or a teacup) of water each day to saturate the compost supporting each petunia, but only 80ml was needed to grow a good plant. In neither case did compost drip after watering. Perennial hanging baskets need to be repotted once per year in early spring or before major growth occurs. This will loosen compacted soil and roots, giving better growth and moisture management, as well as introducing nutrients to the plant. Tube stays put in any direction or angle you choose; Allows you to direct water right where you want it - between the leaves and to the root base The table shows the different applications used and how they were expected to affect growth of petunias. Watering method

Doubling the amount of water applied did not double the amount of flowers produced. Only 8-15% more flowers were produced when the water volume applied was doubled for manually watered baskets. The self-watering basket (SW) produced a similar number of flowers as the manually watered high rate basket (TOPM Hi), but it received about a third less water. This was not intentional, but the water was added to the reservoir which, at times, was not large enough to hold the full high rate dose intended. The questionnaire results confirmed that very few gardeners, even the expert ones, have given any thought to how much water their soil is capable of holding, and therefore how much might be draining away out of sight. This confirms the need for training expert gardeners as well as improving advice to members and wider horticultural community.Irrigation systems automate the delivery of the water, saving time and labour, but they still need intervention to maintain and optimise. They are not a 'fit and forget' solution, and if treated as such are likely to perform worse than a manually watered basket. Scientist Tijana Blanusa and a team at the School of Biological Sciences, University of Reading, with funding from the RHS, set up experiments using petunias and busy lizzies to monitor amounts of water take-up by the plants. Every week or so, fill your soda/water bottle with water. The water should slowly drain out of the holes you made and keep your plants healthy. Instead of watering my hanging baskets every single day, I’ve found I can get away with nearly once a week. When it’s really hot and humid it may need more water. But overall it’s a great and FREE solution to the frequent watering needs that hanging baskets require. One month later Isn’t that gorgeous? The method you use will vary, but often it is sufficient to use a good long handled water wand. Use a light delivery setting, avoiding “jet” as a rate of delivery. Gentle soaking will allow water to penetrate and expand the soil capillaries, keeping moisture in longer so plant roots can uptake water. Again, crowded plants or heavy water users may require watering daily in summer, as there is not sufficient space to store moisture.

baskets with 6 petunia plants that were given one litre water per day on average, produced a similar amount of flowers as baskets given 300 mls water per day on average with most of the excess wasted. I love these for watering baby plants and succulents, keeping moss poles moist, and cleaning dust off leaves. I keep mine on handy for refilling all my propagation vases too. It gives you a steady, fine, thin stream of water for very accurate watering for plants that don't like their leaves or crown getting wet, and watering delicate jungle members. The stem on the spout means you can direct water in between leaves down to soil level easily too without spilling water everywhere. Using double the amount of water also doubled the amount of water wasted, but produced only 8-15% more petunia flowers. Allowing the surface of the compost to dry out isn’t a problem and can actually be an advantage in reducing water lost from the surface. The most efficient system in terms of the number of flowers produced per litre of water applied was the self-watering and low dosed, manually watered baskets. This is because they also had the least wastage draining from the bottom of the basket, the self-watering baskets capture the drainage in their reservoir and there is less run-through using smaller doses of irrigation for manually watered baskets.

Save rainwater rather than using mains water because plants prefer it. All the drip irrigation systems in the trial needed mains pressure to work apart from the solar powered pump system, which used water from a water butt.

Hanging baskets are notoriously difficult to water. A recentRHS surveyfound three quarters of respondents wanted advice on how to water baskets and containers. Janet Manning, former RHS Water Management Specialist, trialleda variety of watering methods to find the best one.

This creates a thrill, fill and spill effect that will make your basket look awesome. The trial results can be used to describe the summer and winter differences in the water cycle at a scale that many gardeners can relate to, ie when there are winter rains, the water is best captured in below-ground reservoirs to be used later. Having the surface of the compost bone dry isn’t a problem, and probably helps to reduce evaporation from the soil, reducing water loss. When the compost is very wet, plants help to dry the compost by evapotranspiration, making space in the root zone to capture the next rain when it comes.Rather than overwatering, just because you can only water at certain times of the day, (which will encourage your plants to use more water), you can fill the reservoir anytime and know that you haven't saturated the compost.
