If you see any warning signs, start spraying your succulent leaves, especially the undersides, with water and insecticidal soap or neem oil. WD-40 or other oil can be used to protect your tools, as most gardeners do not keep them in their original packaging. * It is also a good idea to wash pots and other gardening tools with bleach. If you're interested in fairy gardens, terrariums, or decorative arrangements, then you already know the importance of putting figurines into pots. If you're not familiar with rhizomes, they're like roots, except they grow horizontally.
