Embrace the Power of DIY Seed Starting
Seedlings can be expensive, especially for uncommon or heirloom varieties. Unleash your inner plant whisperer by starting your own seeds in your greenhouse! Here's how:
- Gather your supplies: Recycle plastic containers (yoghurt cups, milk jugs) with drainage holes for pots. Use a seed-starting mix specifically formulated for optimal germination.
- Sow your seeds: Follow seed packet instructions for planting depth and spacing. Aim to start seeds 6-8 weeks before the last frost date.
- Provide ideal conditions: Maintain consistent moisture with a spray bottle to avoid overwatering. Use grow lights or position your seedlings near a sunny greenhouse window for at least 12-16 hours daily.
- Harden off before transplanting: Once seedlings develop a few true leaves, gradually expose them to outdoor conditions for a week before planting them permanently in your garden or larger pots.

Propagate Like a Pro

Did you know, you can create new plants from existing ones? Plant propagation lets you multiply your favourite plants for free! Greenhouse conditions are ideal for these techniques:
- Division: This works well for clumping plants. Carefully dig up the parent plant and divide the root ball into sections, each with a growing eye or shoot. Repot each section and treat them like new plants.
- Stem cuttings: Choose healthy, non-flowering stems from your favourite plants. Remove the lower leaves and dip the cut end in a natural rooting hormone (cinnamon powder works well) before planting in a pot with a well-draining mix.
- Leaf cuttings: Certain plants, like African violets, can be propagated from a single leaf. Cut a healthy leaf with a petiole (the stalk) and plant it in a moist, sandy medium.
Natural Pest Control Takes Center Stage
Chemical pesticides can be costly and harmful to the environment. Luckily, your greenhouse can be a haven for natural pest control solutions:
- Companion planting: Attract beneficial insects like ladybugs and lacewings by planting herbs like marigolds, dill, and chives alongside your vegetables. These beneficial insects prey on common garden pests.
- Neem oil spray: This organic oil repels and suffocates a wide range of soft-bodied insects. Mix neem oil solution according to package instructions and apply it directly to affected plant parts.
- Diatomaceous earth (DE): This natural powder dehydrates insects with exoskeletons, such as ants, beetles, and slugs. Sprinkle a thin layer of DE around the base of your plants or on walkways within your greenhouse.
Bonus Tip: Utilise Recycled Materials

Get creative! Repurpose old windows, doors, and even plastic sheeting to create a budget-friendly greenhouse. Old wine bottles, colanders, and hanging baskets can be transformed into unique planters.
