Can you grow plants in aluminum containers?
Aluminum – aluminum pots are non-reactive, which means they won’t leach chemicals or harmful substances into the soil or the plants. This can be particularly important for plants that are sensitive to certain chemicals or minerals, as well as for those that require specific pH levels in the soil. At neutral or alkaline pH, it’s not a problem for plants. However, in acid soils, the main form of aluminum is highly toxic to plants.Al is considered a major limiting factor restricting plant growth and productivity in acidic soils. It instigates a series of phytotoxic symptoms in several Al-sensitive crops with inhibition of root growth and restriction of water and nutrient uptake as the obvious symptoms.We need to apply lime (calcium carbonate) which will react in the soil increasing the pH and neutralizing the aluminum.
What is easy to grow in a container?
Lettuce, spinach, arugula, and other greens are a perfect choice for small containers (2 gallons or larger). Most greens have a small root system and grow quickly.

How to keep tin cans from rusting?
SPRAY SILICONE: A light coating of ordinary spray silicone may be used to deter rust. Spray lightly, allow to dry, wipe gently with a clean cloth to remove excess silicone. Spray the can with a clear polymer sealant if you like the look of naked metal but don’t want rust. If you’re feeling especially arty — and you have some time on your hands — you can use a power drill with sanding disks and a wire brush attachment to create a brushed metal look.Apply a protective coating: A bit of WD-40 or a similar rust-resistant spray can add a protective layer to the outside of your metal can, avoiding the interior as this could cause issues to plants you water in the future. A rinse and wipe would be advisable come spring to ensure any residue is removed.
