March into Spring: Essential Garden Tasks & Greenhouse Jobs for a Thriving Season
March is a pivotal month for gardeners, a time of transition where we bid farewell to winter’s chill and eagerly anticipate the vibrant growth of spring. For those with greenhouses, it’s a particularly busy period, brimming with opportunities to nurture seedlings and prepare for the season ahead. Whether you’re a seasoned gardener or just starting out, mastering these key March gardening tips will set you up for a flourishing garden.
This article will guide you through essential garden tasks and greenhouse jobs to ensure your plants are healthy and productive. Let’s delve into five crucial activities to tackle in your greenhouse this March.
1. Natural Aphid Control: Protecting Your Greenhouse Treasures
As temperatures rise, aphids become more active, posing a threat to your delicate seedlings and emerging shoots. A key greenhouse job in March is to proactively manage these pests without resorting to harsh chemicals. Consider introducing natural predators like ladybugs or using a gentle soapy water spray. Regular inspections are crucial to catch infestations early. We also recommend wiping aphids off new shoots by gently running your fingers over the aphids to remove and kill them.
- Tip: Encourage beneficial insects by planting companion flowers near your greenhouse entrance.
2. Rot Prevention: A Clean Greenhouse is a Healthy Greenhouse
The damp conditions within a greenhouse can create an ideal environment for fungal diseases, especially in the cool conditions of March. Regularly inspect your plants for signs of decay, such as wilting leaves or mold. Promptly remove any affected plant material to prevent the spread of rot. This simple greenhouse task can make a huge difference to your plant’s health.
- Tip: Improve greenhouse ventilation to reduce humidity and minimise the risk of fungal infections.
3. Hardening Off Tender Plants: Preparing for the Outdoors
With the days growing longer and warmer, it’s time to acclimate tender plants to outdoor conditions. This process, known as “hardening off,” involves gradually exposing plants to sunlight and cooler temperatures. Start by placing them outside for a few hours each day, gradually increasing the duration over a week or two. This is a vital garden task for transitioning plants from the protected environment of the greenhouse to the open garden. Beware, the nights can still be frosty so remember to move your tender plants back indoors before the temperatures drop.
- Tip: Choose a sheltered spot for hardening off, away from strong winds and direct sunlight.
4. Sowing Long-Season Seeds: Getting a Head Start
March is the perfect time to sow seeds for plants that require a long growing season, such as chilies, peppers, and tomatoes. These greenhouse jobs ensure you have robust seedlings ready for planting out when the weather warms. Start these seeds inside to give them the best head start.
- Tip: Use a heated propagator to maintain consistent soil temperatures for optimal germination.
5. Pricking Out Seedlings: Encouraging Strong Growth
If you sowed seeds earlier in the year, March is likely when you’ll need to prick out the seedlings. This involves carefully separating individual seedlings from their crowded trays and transplanting them into larger pots or modules. This crucial garden task provides each seedling with the space and nutrients it needs to develop strong roots and healthy growth.
- Tip: Handle seedlings by their leaves to avoid damaging their delicate stems.
