OK to transplant seedlings into pots w/Miracle Gro potting soil?
Comments (7)its a little early for my zone 5 ... to be putting out tender annuals ... so... work in the garage .. today .. and do one pot.. and see what happens to the babes in the next few days/weeks ... experiments are always better than the thoughts of peeps all over the country .... i presume you have a few to spare.. and if the media is so volatile that it will kill them.. i presume it will do so within the next 2 weeks.. until the last frost date ... so give it a go ..... ken...See Morepotting soil, cheapo stuff or the miracle gro?
Comments (44)Not all is as you might imagine it to be. I save a lot of the stuff I write as a document when the question comes up over & over. Coffee & tea as plant 'tonics' is a frequent topic. Here's what I discovered: Forum discussions frequently center on the question of adding dilute coffee/tea or grounds to plants as a 'tonic', but Arabica (coffee) and Camellia (tea) are known for their toxic alkaloid (caffeine) content and their allelopathic affect on plants as well as autotoxic (poison to their own seedlings) effects on future generations. Caffeine interferes with root development by impairing protein metabolism. This affects activity of an important bio-compound (PPO) and lignification (the process of becoming woody), crucial steps for root formation. We also know that the tannins in both coffee and tea are known allelopaths (growth inhibitors). There are ongoing experiments to develop herbicides using extracts from both coffee and tea that cause me to want to say they might serve better as a nonselective herbicide than as a tonic. I would not use either (stale coffee or tea) by applying directly to my plants - especially containerized plants; nor would I add tea bags/coffee grounds to my container soils. Rob - you can use white vinegar or citric acid (and other acids, but stick with the safer stuff) to lower the pH of your irrigation water (for the acid lovers) to about 5.5. Note how much acid is required per unit (like a gallon or 5 gallon unit) and repeat as needed. Note that pH of freshly drawn water rises as the dissolved CO2 gases off over a 24 hr period, so let the water you'll use rest for a day before adding the acid (first time only) for an accurate read. You'll need some pH paper - like what is used for ponds or aquariums. Al...See MoreOpinions On Miracle Gro Rose Soil
Comments (11)Miracle Gro soil mix has earned a reputation for being toxic to young roses whose root systems are still developing, because its nutrient content is overly rich; too much nutrient available immediately. I suspect it appears to be effective because it pumps a lot of Nitrogen into the plants instantly, giving the impression it is beneficial in the long run. Chances are, the N supply will be exhausted fairly quickly and then you will see what the actual soil components are capable of. If you want something to amend your existing soil with, this is likely a waste of $$$; stick with the amendments you already have at your disposal. If you want a good potting mixture for container grown roses, look to a brand that has a lot of organic nutrient components (manure, cottonseed meal, green sand, alfalfa, fish meal, etc) which will release nutrients as the components break down, slowly, over a long period of time. A steady, slow supply of Nitrogen is much more beneficial to the plant than is a sudden burst of intense nutrient....See MoreMiracle Gro organic potting soil -- needs fertilizer?
Comments (2)Very interesting, I have had problems with Miracle-Gro seedling mix go mouldy-green on me before. I now buy other brands, and don't get the GREEN. I'm not sure of the exact "type" of Miracle-gro product I used at the time, and I can't say the green was detrimental to my seeds....but it kinda grossed me out! good luck and good growing to you...See MoreAlwayzbgrateful
