 4 Questions to ask yourself when deciding what to grow:

  • What do you buy from the grocery store on a regular basis? 
  • What meals show up on your family’s menu each month?
  • Which foods provide the highest value? What vegetables are expensive to buy?
  • What will make you happy to grow in your garden? 

 Top 5 tips for a successful season:

  • Stop tilling your vegetable garden. You should have a permanent design of beds and paths in your garden.
  • Don’t shop at the big box store for seeds or seedlings.
  • Reduce weeding with mulch. The secret—keeping your soil covered.
  • Keep garden records.
  • Make a map of your garden, put it in a binder and then write down everything you plant and when each season.
  • Join a community & share information with other gardeners. Gardening is more fun when it’s a shared with a community of equally passionate gardeners.

  • Gardening from seed has several benefits. With seed gardening, there are more varieties available to you, you know what's going into your food because you are growing it, and you'll save money in the long run, not to mention the great satisfaction that comes with starting from seed.

 

Botanical Interest philosophy:

       Why start seeds indoors?

  • Some varieties are best started indoors because they need particular conditions, and you have more control over the growing conditions.
  • Starting seeds indoors extends your gardening season, allowing you to grow varieties that require longer growing times than your area's natural growing season allows.
  • In the case of perennial flowers, an early start can reap first year blooms.

 

       When is the correct time to start my seeds indoors?

  • Botanical Interests uses the average last frost date as a guideline for when to sow seed. Your average last frost date is usually defined as the first day of the year when there is less than a 50% chance a frost will occur. It's also helpful to know your average first fall frost date so you can determine the number of days in your growing season as well as plan your summer and fall sowings.
  • What types of plants should be started indoors?
  • Plants that require a long growing season to reach maturity.
  • Perennial flowersthat you want to encourage to bloom in first season.
  • Sproutsand 
  • Here are some examples of varieties that would benefit from a head start indoors:

On the inside of every Botanical Interests seed packet you will find the best              growing conditions for the variety.

  • We provide information about special care, organic gardening methods, and tips to improve your garden throughout the seasons.
  • All that's left to do is watch your seeds grow into beautiful, healthy plants!”

 Variables to consider in selection process:

  • Disease resistance
  • Days until harvest

Look at the seed packets  loaded with information

Variables to consider in selection process:

  • Disease resistance
  • Days until harvest
  • Germination time

 Starting from Seed:

  • Let There Be Light: For seedlings to grow properly, they need light. And lots of it.
  • Use Self-Watering Seed Starting Systems: I will never start a seed in a small peat pot again. They just dry out too fast.
  • Use a Good Seed Starting Medium
  • Feed Your Seedlings: Most sterile planting mixes don’t have any built-in nutrients at all.
  • Ventilation and Wind
  • Read the Seed Packet: Most seed packets have a wealth of information

 Recommended Supplies:

  • Soil-less planting mix or seed starting mix
  • Wooden stakes to label trays or rows
  • Seedling flats or pots
  • Thermometer for soil & air temperatures
  • Top soil, peat moss & perlite to transplant
  • Water soluble fertilizer or transplanting solution
  • Artificial light in early season
  • Sunlight – minimum 6 hours

To start from seed or transplants?

  • SEED
  1. More variety
  2. Control of growing environment (organic)
  3. Control of timing
  • TRANSPLANTS
  1. Instant gratifiction
  2. Quality
  3. Available at proper planting time

 Improve success using these tips:

  • Seedlings need light and lots of it
  • Use self-watering seed starting systems
  • Use a good seed starting medium
  • Feed your seedlings
  • Ventilation
  • Read the seed packets
  • Benefit of artificial lights

 A Good Seed Starting Medium

  • Espoma brand
  • 80-90% Sphagnum Moss
  • Perlite
  • Limestone for pH
  • Yucca juice to hydrate and re-hydrate well

 Alternate Option – Self Watering containers

 Seed starting trays and cell packs

 Benefit of Artificial Lights

LED lights are the way to grow

  • LED  technology is continually being developed to address these difficulties. LED Grow Lights have been designed to maximize spectrum and coverage, while minimizing wasted energy and dangerous heat. These lights meet the needs of the crops, not the other way around.
