Planters Matter Part 5 January 15, 2015 Growing Tips Planters, often used synonymous with pots, play a big part in the world of agriculture from home gardening to commercial greenhouse growing. Whether you have one large terracotta planter sitting outside to accentuate your front stoop or you have a thousand small plastic planters in your greenhouse out back there is something here you probably didn’t know. Before you start growing, know what planters are best suited to your chosen plant. This next series of posts will highlight individual styles and materials most commonly used and some that aren’t so common. Today we discuss : Metal Pots Metal pots like all other planter styles have their pros and cons. Much like black plastic pots, metal pots generally heat up very quickly in sun and can cause damage to your plants and micro-organisms if exposed for too long. This can cause the interior soil to dry extremely fast resulting in extensive root damage so if used be sure to use a clay or plastic pot liner as insulation. But on the positive side the direct sunlight will not degrade your pot in the same way that sun exposure does to plastic and they are much less likely to chip or break. Drainage can be a large factor in deciding whether to use a metal pot or not but if you’re okay with putting a couple holes in the bottom yourself that’s no longer an issue. Rust may also be something to consider, in sub-tropical and rainforest climates it would be wise to apply a rust inhibitor or keeping them under cover. This leads nicely into our next point; consider the type of metal used. When re-appropriating an antique be sure to check that it isn’t made of lead or lead-coated as it could cause significant damage to your health and your environment. Some heavier metals may not be appropriate for balconies or ledges where weight restrictions might apply so keep that in mind as well. Although the cons seem to outweigh the pros in this circumstance, it should be noted that we here at Growing Society are big fans of metal pots as Cachepots for their old-timey aesthetic.
