I use it regularly on outdoor stuff - have for years. I like it, though I really couldn't say I find it to be head & shoulders above stuff like Osmocote or MG. Though it makes no difference to plants where they get their nutrients from, in the back of my mind I have this feeling that the lower the concentration of fertilizer salts in a container, the less the likelihood of problems with water/nutrient uptake. Frequency of applications vary by plant. Because I am a bonsai grower, I often fertilize at and above recommended doses, but there are plants whose development I want to slow, too. In actuality, the best fertilizer program for best plant health doesn't usually include the inducing of the most robust growth. Heavily fertilized plants will usually be found to have less energy in reserve to fight off insects & infection with various pathogens. In addition, the highly succulent growth produced by heavy applications of nitrogen is favored by insects, making them a more likely target for infestations. Though some might argue the point, it is near impossible to keep containerized plants happy without supplemental nutrients (except for the small percentage that prefer a very spare soil). For most container growers (and I'm talking about the average Joe/Jill) a good policy would be to watch leaf color carefully. If you see signs of chlorosis, or venation, give the plant a half dose of your favorite balanced fertilizer. If, in a week or so, color doesn't improve, another dose is in order. Though the minors (micro-nutrients) are beyond the scope of your question, scarcity of certain elements, particularly in containers, can be a problem. I use a micro-nutrient frit in all my container soils, but as of yet, I have only found it in 50 lb bags & it is expensive (but dosage is small & a little really goes a long way). There is a major producer of fertilizer that has a liquid product on the market that advertises it contains the minor elements. Though I haven't tried it, I would really recommend you try it for containers & houseplants. I'm not sure, but I think Schultz makes it. Perhaps some one can help me here? Good luck. Al

I sometimes add a few ounces of smelly fish products like fish emulsion, fish meal, catfish feed, etc. to my 5-20 gallon aerated compost tea recipes. If you have enough rich aerobic mature compost, and a few ounces of molasses products, and plenty of constant aeration in your brewing container, you can aerate fishy compost tea with no problems. The right aerobic microbes can overpower the stinky anaerobic microbes in the aerated liquid. I do it a lot, and my finished brew smells like a pleasant, yeasty wine. Happy Gardening!

Depends how much fertiliser is already in your soil. Many perennials will not need additional fertiliser for several months in a potting soil. If your potting soil is free of fertiliser then they might need some as soon as the seed leaves start to dry up or drop off. Aim for about 100ppm of the big three nutrients, you can double the strength when they get beyond the seedling stage. Annuals, especially modern hybrids, usually need more fertiliser.

I've got a hose end sprayer like that too but until I have to water every day in the summer I use the bug sprayer. Also some of my plants are too small to hit with the hose end one yet. Most of my pots are 11 in. X 14 in. I use the hose with the long handled shower head type end that doesn't let the water dig up my pots. I read that bugs don't like the seaweed extract.I hope it's good info-true. Looks like I'm lucking out in the Aphid Dept. this year so far. I had tons of Aphids but they are now just mummies. I didn't think the wasps (Golden Chalcid)I let go last year were supposed to overwinter but it seems like they might have. Lots of hard light brown dead,hollow aphid mummies on my plants in the last few days. YEEE HAAAAAAAAA!Eat um up.Get um boys... Even the aphids I have inside are getting mummified. Now if the Green Lacewings come back I'm not going to know how to act. Grasshoppers are allready out though.The big brown suckers. I'll find something to fix their wagons soon.
