Large & In-Ground Plant Care Kits

Feeding for big trees, in one simple routine

Once a tree moves into a large container or goes into the ground, it feeds from far more soil than a patio pot, and the small kit that kept it fed before runs out long before the season does. An underfed tree shows it plainly: pale or yellowing leaves, thin new growth, blossoms that drop instead of setting, and fruit that never sizes up.

These large and in-ground care kits are built for that stage. Each one carries enough season-long feeding, micronutrient support, and bloom and fruit support for a big tree, applied as one simple routine instead of four separate products. Same proven approach as our container kits, scaled up to match a larger tree's appetite.

How the kits are sized

Every kit is sized by total soil volume rather than by a single pot, which is what lets one kit cover several arrangements. A large kit feeds roughly a single 30-gallon container tree, two 15-gallon trees, or three 10-gallon trees for a full season, or a young to mid-size in-ground tree. A mature standard tree with a wide, established root zone will take more than one kit to cover the full area under its canopy.

If you are feeding a single small tree in a 3-gallon pot or under, you want our container care kits instead, which are portioned for that smaller root zone.

What is in every large kit

• A controlled-release granular feed that releases over six to eight months, matched to how trees actually grow, so nutrition arrives steadily instead of washing straight through.
• A micronutrient spray that corrects the iron, manganese, zinc, and other trace-element shortages that show up as yellowing leaves.
• A calcium and boron feed that supports blossom quality and fruit set, for more and better fruit.
• A pre-measured schedule with a size chart, so there is no guesswork about how much a given tree needs.
  

Choosing your kit

Pick the kit that matches your tree, and feed to its size. The plant-specific formulas, citrus, fig, olive, avocado, berry, and fruit tree, each carry the nutrient balance that plant needs, so the large citrus kit is tuned for oranges and grapefruit while the large fruit tree kit suits apples, peaches, and the rest. Match the kit to the plant, then feed to the tree's size using the chart inside.
