One thing I’ve found helpful when transplanting seedlings is to use a seaweed-based fertilizer. It helps reduce transplant shock and promotes root growth.
The article didn’t mention the importance of pruning suckers on indeterminate tomato varieties. Pruning these excess shoots can help improve airflow, reduce disease risk, and increase fruit production.
I’m afraid I disagree with the idea that leggy seedlings should always be buried up to their first set of true leaves. In my experience, burying the stem can sometimes lead to rot, so it’s better to stake the seedlings for support.
While the article provides some good tips, it’s essential to mention the role of mycorrhizal fungi when transplanting tomatoes. Inoculating the roots with these beneficial fungi can greatly enhance root growth and nutrient uptake.
While I appreciate the recommendations for fertilizing tomato seedlings, I caution against overfertilization, as this can lead to excessive vegetative growth and delay fruit development. It’s important to follow the package instructions for any fertilizers used and to monitor the plants for signs of nutrient deficiencies or excesses.
I agree that we should harden off tomato seedlings gradually before transplanting, but protecting them from the harsh sun and wind is important during this process. You can use shade cloth or row covers to provide protection until the seedlings acclimate to outdoor conditions.
I disagree that all seed-starting mixes are created equal. Some mixes may contain high levels of nutrients or moisture-retaining materials that can lead to problems like damping off. It’s important to choose a high-quality, sterile seed-starting mix specifically formulated for growing seedlings.
While I agree that seed-starting trays can be a good option for starting tomato seedlings, using individual cells or pots can be even more effective. It allows each seedling to develop its root system and reduces the risk of transplant shock when moving them outside.
I disagree that we must start tomato seedlings indoors in all regions. In warmer climates, such as in the southern United States, it may be possible to start seeds directly outside. However, it’s important to wait until the soil has warmed up sufficiently and all danger of frost has passed.
