I disagree about deadheading. I do it to all my petunias regardless of the type. I have to do a haircut to all my petunias. I feed once a week, but as the summer is moving on (2022) I think I may do it twice. I have a large number of potted petunias so a lot of work ahead of me. This year I am trying rain barrels, so I am trying to always water with rain water.
Could you please advise as to why my petonias wilt away as soon as I water them. Excessive sunlight or excessive water seems to wilt them away and being from a sunny climate, it is very difficult to grow these plants, Although I assumed that here in Colombo , Srilanka with its bright sunshine in the morning hours that the petunia's would bloom well with its bright colours. But I keep buying new plants and all of them withers away after a few days. I love these flowers and simply cannot understand what I do wrong. Does it need a shady place to grow and how often do you have to water them ?
Try putting a tablespoon of Urea 46-0-0 fertilizer in every gallon of water every time you water. Poke your finger in the soil and make sure it’s beginning to dry before you water. Keep them in the sun
Plants will survive on city tap water (chlorinated) but they won’t thrive. Rain water is always the best but summers are so dry lately (Ontario) that my rain barrel never fills. Thunderstorms don’t count as the ground or planters seldom absorb such fast moving water. I try and water everything long and deep once a week. Planters when they are dry to the touch. Watering short and often is not a good idea. Ready made baskets are soon root bound so putting together your own baskets works well but not instant. I am not from Heemans but I drive two hours to shop there:) This was a very informative video. But pruning won’t help if your plant is root bound. Root bound plants have nowhere to grow. Last year the hybrid petunias I bought did better in partial shade.
Here in Ontario we have few options so EndAll is the strongest spray you can use (soap plus pyrethrum). Using soaps or products that can increase phototoxicity (burning under suns rays) should be used on cloudy days or just before sundown so they can go to work, dry off and minimize the impact on the plants/flowers.
That was ok. The only thing was...well how do we know what petunias we have at home and different in every country? So we don't know which ones to deadhead or not to deadhead. Also it would've been helpful for newbies if you went in closer to show us where you went and cut. Those are my comments. Thanks
Great questions. We made this video to help our loyal gardeners here in London, Ontario, Canada (and area). We're happy that it's been helpful and viewed by gardeners all across the world. I would suggest that if you aren't sure that your local garden centre is a great resource to ask what type of petunia you have and if it can be trimmed. I don't know of a petunia I wouldn't feel could benefit from pruning back to stay bushy. Varieties that are sold for more $ are often the premium kinds that don't require deadheading. Things like Wave petunias, Proven Winner varieties and petunias sold in single pots are almost always (at least here) premium varieties you don't need to deadhead. Unless they're a double petunia, they do need deadheading. Hope this helps! ~ Will
Those petunias don't have the same habit (those are more upright and these are much larger/faster growing). With those you would be deadheading each petunia after it's finished whereas these are self-deadheading. If you look at the video we're about to share on pruning coleus, that would be a more appropriate pruning style for garden petunias. :)
That is a water soluble fertilizer we use here - it's similar to an All Purpose Miracle Grow. The formulation is 20-20-20 and it's just called that. We offer it at a very affordable price in the greenhouse as it's professional grade and we want people to use it make you happy with your plants (and us) ;) ~ Will
We use two blends, one for small potted plants is 75% peat, 15% perlite 10% vermiculite. The baskets, a larger pot for mature plants, we use a 85% peat, 15% perlite. We find they like that very much but there's lots of similar mixes or ones with substitutes (including some with coir, hemp and bark) that could work too. They do like a low pH from their water/fertilizer if you can give them that. Reduces the risk of leaf yellowing from iron deficiency.
@@WendySS22 You can use iron chelate if it's actually an iron deficiency (yellow leaves is lack of N, not Fe) on most plants. If you have lime-coloured leaves with dark green leaves and it's sometime like million bells or petunias, then you could push more fertilizer generally as they can be hungry in summer. Iron + more fertilizer is the most ideal combo to perk up these two plants.
The trick to that is to cut them back more aggressively. Petunias can focus on new growth at the tips more and develop bald spots in the centre of the container or planting in a garden. Cutting the ends back more aggressively will trigger more new growth in the centre/middle to continue to have a full, thick plant. :) ~ Will
Yes, they're best planted in October/November and grown over the winter if you're in Florida. gardeningsolutions.ifas.ufl.edu/plants/ornamentals/petunia.html
I'm not personally familiar but a quick search shows yes, you can. timesofindia.indiatimes.com/life-style/home-garden/six-easy-maintenance-plants-you-can-grow-in-winter/articleshow/50636568.cms
Fertilizer is not harmful to bees, it's still N-P-K in a different form that's applied to the soil for the plant to take up via the leaves. No pesticide properties. Using an organic or synthetic is a personal choice but both will help the help and either harms pollinators :)
I'm sorry, we're a retail greenhouse that sells the plants to our local community. You'd be best to contact a seed seller who exports with this request.
