You can use Osmocote Plus on all these plants with confidence. When you use Osmocote on houseplants use half the recommended amount for outdoor plants as houseplants grow much slower. The amount to use is always listed on the Osmocote label. The Osmocote contains a combo of macro and micro nutrients to satisfy all plants and what the plant does not need it will not take up. The slow release formula also eliminates the danger of using too much plant food and burning the foliage of your plants. The granules release the fertilizer as the plant needs it and will last up to six months to slowly feed your plants. Keep growing, Marianne Binetti
