Small pots will dry-out faster than larger pots because they have less soil. Watering will be your biggest challenge in maintaining your hanging baskets. Choosing a larger pot now, can make maintaining your basket much easier.
In general, water plants in hanging baskets when the soil surface becomes dry to the touch. On hot, sunny days it may be necessary to water once a day. When watering hanging baskets, be sure to apply water until water begins to flow out the bottom of the container.
If a plant is overwatered, it will likely develop yellow or brown limp, droopy leaves as opposed to dry, crispy leaves (which are a sign of too little water). Wilting leaves combined with wet soil usually mean that root rot has set in and the roots can no longer absorb water.
Too little, and they're drooping like a wilted teabag. Too much, and they get a soggy bottom and grumpy leaves. Overwatering means yellowing leaves, a general feeling of flop (science calls it wilting!), fuzzy soil, and a pot that feels like it could double as a weight.
Be careful not to overwater, as these can succumb to root rot fairly easily if kept too wet.
Check your hanging baskets every day and water if required. This is vital if you want big, healthy baskets filled with flowers. Water early in the morning to help your plants cope with the stress of very hot days. In a heatwave, you may need to water again in the evening.
Feeding. Types of feed you may need to use: high nitrogen feed for growth; tomato feed for the flowers; and a balanced feed Miracle Grow for an all-round feed.
Water potted plants
Water pots well. Put saucers beneath them to collect water and increase humidity. Move them to a shady spot where they will dry out less quickly. If you can't move them, cover with shade netting or fleece.
Caring for Hanging Baskets
Soil: Fill with a commercial potting mix, as garden soil is too heavy and dense. Potting mixes include materials that hold water and improve aeration and drainage. They will be sterile and free of the soil pathogens that can be found in garden soil.
It should be damp, but if you grab a handful you should not be able to squeeze out much water. Step 3: Once you have the soil moist, it is time to line your baskets with plastic. I have been using plastic bags to line my baskets for several years.
Watering petunias
Watering should always be from the bottom, so that the leaves do not become stuck with the glandular hairs located on it. If the water from the tap is too hard, it helps to boil it for a few minutes before watering. This causes the minerals that make the water hard to be precipitated.
Along with fertilizing, watering is the other biggest reason why hanging basket plants struggle. Or more to the point, inconsistent watering. Whether you are watering your plants too little or too much, both will cause big issues for your plants. Over-watering plants will cause problems with a plant's roots.
Yes, you can absolutely waterproof a wicker basket if you want to use it outdoors all year round. You'll need to apply two layers of waterproofing varnish or sealant and wait for it to dry completely before using your basket. This will protect it from water damage, mould, mildew and dry rot.
They're prone to drying out in hot weather, so will need regular watering to prevent the plants from losing too much water.
Petunias do best with consistent water. Hanging baskets dry out quickly, so it's important to check them frequently. If the soil feels dry 1-2 inches down, then it's time to water. During hotter weather, this may mean watering once or twice a day.
Some times these baskets have dried out in between waterings, so there are some leaves that are brown and dried. In other cases the soil has been kept too wet and the plants are yellowing from over watering. Some annuals slow their flowering because they haven't been deadheaded…
The good news is that most plants will bounce back between 7-14 days if they're given proper care (which includes rehydration). If this isn't possible because major damage was done or little healthy root system exists then expect about 2 weeks until improvement can be seen.
How to check for root rot. The main signs to look out for are: yellowing, wilting leaves, wet soil that isn't drying, black, wet roots, quickly declining health, and stunted growth.
Using a coconut coir liner helps with water retention. Using good quality compost will help and many are created to help retain moisture. There is also the option to mix in vermiculite or perlite, which can help and incorporate some worm compost. Covering the soil with a mulch such as grass clippings can also help.
