Gardening Know How has published a practical guide to growing plants from fruit seeds and vegetable scraps on a sunny kitchen windowsill. It describes methods for citrus, avocado, apple and pear seeds, plus regrowing edible leaves from cabbage bases and carrot tops; results and timelines vary, and seed-grown fruit trees may not produce good fruit.
Gardening Know How has published a guide to growing plants from fruit seeds and vegetable scraps on a kitchen windowsill, with instructions for citrus and avocado seeds, apple and pear seeds, cabbage bases and carrot tops. The advice offers readers a low-cost way to try indoor propagation, while warning that seed-grown apple and pear trees generally will not produce familiar, good-quality fruit.
For citrus seeds, the guide says to wash away pulp, sow the seed about one-third of an inch deep in moist potting soil, and cover the container to retain warmth and moisture. It recommends placing the pot in a bright, sunny spot and removing the cover after growth appears. The report says citrus seedlings can reach about a foot tall by their first birthday under suitable care, but fruit may take around a decade. It presents citrus chiefly as a foliage houseplant, with glossy, fragrant leaves.
For an avocado stone, Gardening Know How recommends suspending its broad lower end in water in a bright place with indirect sunlight. The water should be changed every two to five days and kept at a level that covers the base of the stone. After the seed splits and develops roots and a stem, the guide says to move it into potting soil. It notes that sprouting can take up to two months and that pruning the stem can encourage branching.
The report advises cleaning apple and pear seeds, then chilling them in a sealed bag with slightly damp paper to simulate winter. It says roots may appear around the sixth week, but cautions that trees grown from these seeds usually produce small, acidic fruit rather than the parent variety. The guide also suggests shaping them as bonsai trees. For edible regrowth, it describes cabbage bases as a source of cut-and-come-again leaves and carrot tops as leafy herbs for uses such as pesto, alongside tips for saving seeds for free plants.
A Low-Cost Indoor Growing Project
The methods make use of seeds and scraps that many households would otherwise discard, giving readers an accessible way to experiment with plant propagation at home. They can also produce leafy indoor plants or small quantities of edible greens without buying established plants, though results depend on the seed, growing conditions and care.
The guide distinguishes between growing a plant and growing a reliable food crop. Citrus and avocado seeds can make attractive foliage plants, but their lengthy timelines and uncertain fruiting prospects matter to anyone expecting a quick harvest. Apple and pear seedlings are particularly unsuitable as a dependable route to familiar fruit, according to the report.

Different Seeds, Different Timelines
The report frames windowsill propagation as an indoor gardening activity that can be tried with children or adults, particularly when outdoor gardening is less appealing. Its recommendations vary by plant: citrus seeds go directly into moist soil, avocado stones are started in water, and apple and pear seeds need a period of cold treatment before sowing.
These are practical instructions from Gardening Know How, not reported results from a controlled test. The article’s timelines are presented as expectations rather than guarantees. The supplied source does not provide a publication date, independent trial data or a comparison of success rates among methods.
Success Rates and Harvests Vary
The source does not quantify how often the seeds or scraps successfully grow, or specify the exact light, temperature and watering conditions needed in every home. Its timing estimates—including citrus reaching about a foot in a year and apple or pear roots appearing around week six—should not be treated as guaranteed outcomes.
It is also unclear how much edible produce cabbage bases or carrot tops will yield, or how long regrown leaves remain productive. The guide warns that apple and pear seedlings are unlikely to match the fruit of their parent trees, and it does not promise that citrus or avocado plants grown indoors will bear fruit.
Try One Method at a Time
Readers can follow the relevant method using clean seeds or vegetable bases, a suitable container and the light available in their home, then monitor growth rather than assuming a fixed schedule. For avocado stones, the guide calls for regular water changes; for apple and pear seeds, it recommends checking the damp paper weekly during refrigeration.
No follow-up study or additional development is identified in the source. The immediate next step is simply to test the methods and see which plants establish under local indoor conditions.
Key Questions
Can I grow a lemon plant from a seed?
Yes. Gardening Know How says to wash the seed, sow it about one-third of an inch deep in moist potting soil, and keep it warm and covered until growth appears. The guide says fruit may take around a decade, so the plant is better treated as a foliage houseplant in the near term.
How long does an avocado stone take to sprout?
The timing varies. The guide says an avocado stone can split quickly but may take up to two months. Keep its lower end in water in a bright spot with indirect sunlight, and change the water every two to five days.
Will an apple tree grown from a seed produce the same apples?
Usually not, according to the report. Seed-grown apple and pear trees generally produce small, acidic fruit, so the guide suggests growing them as ornamental trees or bonsai rather than expecting familiar fruit.
Can vegetable scraps produce edible leaves?
The guide says cabbage bases can regrow leaves for salads and stir-fries, while carrot tops can provide foliage for uses such as pesto. It does not give a yield estimate or guarantee how long the regrowth will continue.
