Planting instructions for bare-rooted succulent plants
Q: I would like to order a few Adeniums from your selection. You website says "shipped barerooted". What do I need to know about potting these plants before I order?
A: Adeniums do not require much soil; large 4-5"wide caudex plant can be grown in 1 gal pot. After unpacking the plants, position it in a pot, size of root system. Use only well-drained soil with high content of perlite and/or sand. Cactus mix can be used too, although we recommend using our special TopTropicals professional soilless potting mix. Water once and keep in warm (75-80F) place in filtered light. Do not water again until soil dries on surface. Once the plant is established and starts growing new leaves (may take a few weeks), gradually move it into brighter light. Then you can start fertilizing it. You may place shells and lime rocks on top of adenium planting, as these plants benefit from slightly alkaline soils.

Growing gardenias indoors
From Brian B, WI: Just wanted to share this photo of one of the plants my parents got from you 3 months ago.
Q: Gardenia taitensis is my favorite gardenia. I would need to keep it indoors under a grow light. Is it worth trying to grow indoors or is really difficult? If so, can you recommend and indoor plant that has big fragrance and blooms often?
A: When growing gardenias indoors, four most important factors must be taken in consideration:
1. Bright light (Southern window and/or proper lighting set up)
2. Proper watering (gardenias love water, but roots are very sensitive to excessive water)
3. Rich organic soil with perfect drainage characteristics, regular feeding with high phosphate component and micro-elements containing Iron or Ferovit.
4. Insect control (inspect underneath leaves regularly and apply systemic or on-contact treatments as needed). See Top Tropicals video on easy insect control.
We definitely recommend Gardenia taitensis (both single and double flower varieties) for indoor culture. Another species, Gardenia vietnamensis, is even easier in cultivation as it takes wide range of conditions and may tolerate slight overwatering (unlike other varieties which are more sensitive). These three mentioned gardenias are somewhat tolerant to low light conditions. Under a proper care, they will grow successfully even in bright shade, however for blooming they require as much light as you can provide. Properly adjusted growing light may be helpful. You may refer to our article about indoor plant lighting in our magazine Tropical Treasures, Issue # 15, or website page

Seeds germination in summer
Q: What is the best way to germinate seeds in summer? Should I keep trays indoors or put them outside?
A: Summer is the best growing season for plants, and for their propagation. Seed germination process of tropical plants usually benefits from warm, and even hot temperatures, so keeping pots with seeds outside in full or partial sun can be the best way. However some seeds may be more sensitive than others, or require slightly cooler or higher temperature for germination. These are a few tips that may help:
- For seed germination, use only well drained mixes, containing either peat moss or coconut fiber to retain moisture. Some succulents may require adding sand to the germination mix. You may also try our Professional Formula Seed Germination Mix.
- Large tropical seeds, like palms, or seeds of Fabaceae (Bean) family, can be grown in full sun. Their germination will benefit from higher temperatures (up to 90-95F). Make sure to keep soil moist. Cover them well, with 3/4 to 1 inch of soil.
- Fruit seeds (large size) should be germinated either in individual cells or small pots (3-4"diameter).
- Small to medium size seeds can be grown in so-called community pots. Seedlings can be separated after they establish their first roots.
- Tiny seeds should be planted closer to the surface, covered with only 1/4-1/8 inch of soil; some seeds require bright light for germination, so full sun will be a plus. Some small seeds like Ficus for example, prefer to be broadcasted on the surface, uncovered. Put containers with such seeds in bright shade, as you don't want the surface of the soil to dry out.
- Once your seeds sprouted, move them in filtered light - bright to medium shade depending on tenderness of the species. (Gingers prefer shade, while succulent sprouts can stay in brighter light). Regardless of water/sun needs of the species, all young sprouts and first leaves are sensitive to hot sun and may get burned or even killed. Once a baby plant has a few leaves and well-branched root system, you may start moving trays into a brighter light.
- Do not overwater young seedlings, keep soil slightly moist but not soggy.

New video: Cheena
Jackfruit x Chempedak Natural Hybrid - Jackedak
Jack-edak is a highly recommended variety grown in TopTropicals garden from a seedling of Cheena (Jackfruit x Chempedak) that fruited for us within 3 years from planting. The fruit (20-25"size) is probably the best we ever tasted! It is super sweet, crunchy and has a rich, pleasant, excellent flavor. It has very little latex which makes it easy to handle when cutting up. The tree produces at the very base of the trunk, so you can prune it as short as you want. Our tree survived light frosts as well as 48 hours of 3 ft flooding, with no damage! Cheena is a natural hybrid between Jackfruit and Chempedak. The tree has an open, low and spreading growth habit and can be maintained at a height and spread of 8 ft with annual pruning. Cheena is a consistent producer. The fruit are up to 25 lbs, long, narrow and uniform in size and shape. The skin is green, with blunt spines that yellow and open slightly upon maturity. Comes true from seed.
