1 There was a lot of work going on in the head house of the main greenhouse. All these beautiful begonias were just repotted.
2 Many more needed rehoming, and a large number of these plants had not been repotted in several years.
3 It's good to repot or change the soil every couple of years - potting mix elements break down over time and lose draining qualities and airspaces to hold oxygen.
4 This is begonia 'heirloom' with dark green foliage. Begonias actually like to be dry - only water when the top inch of soil is dry.
5 Begonia 'Silver Sheen' has a compact growth habit which easily adapts itself to windowsill settings. The medium sized leaves are so eye catching with its iridescent silver frosting color.
6 Begonia 'Othello' is a rhizomatous type with medium spiraled leaves.
7 Begonia 'soli-mutata' has copper textured foliage with silver-green striping.
8 Begonia 'Madame Queen' has large, ruffled-edge leaves that rise up from the pot in an impressive manner. The olive-green color boasts a rich red underside.
9 Wilmer placed a begonia into a pot to ensure it was the right size. Don't repot into too big a container - best to go up only one size.
10 Place a clay shard over the hole in the bottom of the pot to help drainage. I also like to use clay pots. They allow proper aeration and moisture to penetrate through the sides and to the plant.
11 For growing begonias indoors, use a soil-less mix - one that is mostly peat-moss based with additional perlite and/or vermiculite to improve aeration around the roots.
12 A sprinkling of Osmocote fertilizer mixed into the potting mix after it's in the pot will provide a good supply of nutrients to the plant for a few months.
13 Wilmer scooped a bit of the potting mix into the pot.
14 He gently gently removed the begonia from the old pot.
15 Loosened the roots with his hands, and placed it into the new vessel.
16 Try to plant it slightly deeper than it was before.
17 More potting mix was added around the plant, and patted down.
18 Any viable leaves that fell off during repotting were saved for future rooting purposes. Begonia leaves root easily. All you need to do is push its stem into potting soil, and keep it moist. After a few weeks, or more, you should start to see new leaves emerge. When the roots are fully established, you can pot up the new plant.
19 Begonia 'acetosa' has velvet cupped leaves with red undersides. It tolerates lower humidity than most, but needs a lot of light.
20 Begonia 'River Nile' has vibrant green foliage with chocolate brown around the edges.
21 Wilmer moved onto the next begonia.
22 He loosened the root ball by hand and gave the roots a slight pruning to encourage new growth and aeration.
23 Wilmer chose a taller pot to accommodate the plant's exceptionally thick hanging stems.
24 It looks much better after being repotted.
25 The next begonia was smaller, and only needed a little loosening of the root ball.
26 Wilmer placed it into the new pot.
27 And then packed the soil down around the plant to remove air pockets which could fill with water.
28 Begonia 'carolineifolia' is an exotic looking begonia that has large, glossy leaves divided into leaflets joined at their bases.
29 The stems of the begonia 'carolineifolia' are exceptionally thick, and show the scars of felled leaves.
30 While Wilmer held the pot, my head gardener, Ryan, pulled the plant out.
31 Carefully, they scratched and loosened the roots.
32 And, a new pot was prepared with a shard at the bottom and a layer of potting mix with Osmocote.
33 A beautifully repotted begonia.
34 My collection is massed together on one of the long sliding tables in this main greenhouse. After repotting, Wilmer returned all the begonias and arranged them so there was ample space in between each pot.
36 Wilmer positioned a few pots on top of other upside down pots to add texture and make use of the vertical space.
37 They all looked so beautiful.
