Irene, I'd like to send you a personal message, but your settings don't allow. Maybe you'd consider sending me your email addy in a Houzz message? Sometimes explanations get lost in the back and forth between people with different viewpoints, but the fact is, soils with a large % of fine particles are always going to pose limitations that result from too much water retention. Even though that fact is carved in stone and can't be argued (because it's governed by predictable laws of physics), there are those very few that insist on arguing the point over and over. Any roots existing within the perched water column will be deprived of O2 for the duration of the saturation. I made that last period bold, but you probably didn't even notice. ;-) The question isn't whether geography or hot dry hurricane windy conditions lift the limitation imposed by the saturation, they don't; the only question is, "How long will the limitations last". In many cases, the answer is measured in weeks, in some cases, in days. A good guess about how a soil like Mg amended with some bark & perlite (let's say 5 parts soil, 1 part perlite, and 1 part pine bark) performs might go like this: Day 1, grower waters established houseplants heavily, to beyond saturation, so water exits the drain. At that point, limitations are most severe. Day 2-5, the degree of limitation gradually decreases until day 5 when the soil is reasonably well aerated and the plant is pouring energy into replacing the fine roots killed by the soggy conditions. Day 5-6, The plant has grown at it's best these 2 days because the soil is moist and about as well aerated as it can be. Almost all the roots killed by saturation have been replaced at a considerable cost in terms of energy outlay. The plant is pretty happy, but the soil is now becoming too dry for the plant to efficiently take up water and the nutrients dissolved in water. It's on the verge of suffering drought stress. Day 7, the grower waters, cycle begins anew. That isn't an exaggeration. It describes a soil that needs weekly watering. Now, a soil in a soil that holds little perched water. The soil is based on a very high % of coarse material (pine bark, perlite, peat or a water retentive bagged soil). NOTE that the ingredients are the very same ingredients as the soil discussed immediately above. The ONLY difference is the ratio of ingredients used. Day 1, grower waters established houseplants heavily, to beyond saturation, so water exits the drain. At that point, limitations are most severe, but still minimal because the soil is designed so the ht of the perched water column and saturation is minimal. Day 2, Perched water is gone, the plant is enjoying a well-aerated soil from top to bottom. Fungus gnats on notice to find more favorable accommodations. This continues until day 4 or 5. Day 4 or 5, fungus gnats have sent out scouts. Other's making preparations to leave this God forsaken place. Plant still happy, but need to water growing imminent. Day 5, grower waters & cycle begins anew. The only price paid for the second scenario is the need to water more often. The first soil was 'amended' with pine bark and perlite, so those would have been on hand anyway. Some might say I'm not going to water 100 plants every 4th, third, every other, or even every day. That's fine, but that convenience demands a soil with enough water retention to get you through whatever interval is desired by the grower. The grower might like the respite from frequent watering, but the plant won't. Convenience very often comes at a price to the plant. That's not judgmental, it's simply how things work. The gritty mix you mentioned holds no perched water if made correctly, so plants are happy from watering time until such time they need another watering. Again, because we've moved away from a perched water table entirely, the need to water the gritty mix comes more frequently than say the 5:1:1 mix, and much more frequently than a soil like you're using. It's also sometimes a challenge to find the exact ingredients, but because the gritty mix recipe I offer as a starting point is nothing more than 1 way to embody a concept, it can be worked around fairly easily. I'll watch for a message with your address. Al

If you don't have a bottom on your container then why don't you just double dig down? Free dirt and all that -- yes, it is work -- trust me, I know! If you decide to buy topsoil here's a word of caution -- most "topsoil" is actually not topsoil. Read the ingredients before you buy! Most "topsoil" ingredients are "forest products, peat, compost, etc.". Black Kow (as in Black Kow compost) does sell topsoil but I only found it at a small feed & seed. Remember your results depend upon your prep work -- If you do it right the 1st time all you should need to add is some good compost along & along. Good luck with whatever you decide!

Hi aptosca - It said - for potted plants. How are you to know that doesn't mean house plants? That was one of your questions. The terms potted plants and house plants are often used interchangeably, but there is a difference. All houseplants are potted, but not all potted plants are grown in the house; many people have potted plants outside, on patios and porches, or summering their houseplants outside, or just growing-on plants for size or whatever - many reasons. Plants grown outside in pots tend to dry out faster than plants grown indoors, and that's why some people prefer "water retentive" soils for outdoor potted plants. But one thing is true outdoors or indoors - wet soil that never dries out makes for wet roots, and wet roots make for dead plants. As you can see from reading all of this thread, there's a lot of 'different strokes for different folks.' It's one reason that you find so much conflicting information if you do much research. One thing that's absolutely true, though, is that if roots stay too wet, plants die. But... That's not always true, either, because many plants are incredibly, amazingly adaptable. Species that are known to hate "wet feet" sometimes adapt to living in a constantly wet - I mean soaking wet - pot. I know, I have one. This is another source of much conflicting information. My advice to you would be to try what seems reasonable to you, what seems to fit your own requirements best. If things don't work as well as you would like, try something else. Even if you are satisfied with results, go ahead and try something different, just as an experiment. That's one reason you never get tired of working with plants, once you get into it.

Eeeek, not a good idea, brink. Mothballs are highly toxic...not just to wildlife and pets, but you! They are not intended to be used other than in an enclosed area to kill insects. Actually, the fact that they can be deadly to non target animals that may ingest them is why they need to be removed from public use. Holly, my favorite tip is to sprinkle cayenne pepper liberally where those critters dig. I buy a big canister of it at Costco every year and use it generously. It helps keep them out of seed beds, new garden plantings, and my containers for cuttings and flowers. Has no effect on birds, so you can even use cayenne in birdseed to keep the squirrels at bay. I have a couple of wooden propagation boxes that I use for cuttings and divisions and I don't want anything walking around in there! I lay hardware cloth on top of the box and weight it with heavy rocks! So, yes.....wrangling the squirrels and chipmunks are an annual event for me.
